This numbers matching Mopar deserves a chance to run again. But first, Nick has to see if he has fixed the oil leak that stumped the engine builders who tried before him.
PLUS! We are excited to welcome our new sponsor to the channel.

Watching Nick working on that 383 makes my older brother and I miss our Roadrunners. His was a 1969, 440, 4 speed hardtop. Mine was a 1968 , 383, 4 speed coupe. We pretty much ruled Athens, Texas back in the 1970s.😃
Got to be so happy when finally defeating a demon like that!
Good job, Nick. I’m 69 yr old, those 13 hour days make my bones weary, and I’m not up and down on concrete floors all day like you are.
What Nick did was a very well-known technique to repair big block rear main seal leaks by old school Mopar mechanics. Taking a bit off the rear seal retaining block to provide a tighter clamping force is the solution used for decades.
Just a question, do you need to be concerned about premature wear on the seal if it’s clamped tighter?
@@Mr1965impalaIt just restored the tension on the lower seal lost to the higher crankshaft height due to the line bore.
@@Mr1965impala Dale. Nick was following the crankshaft by adjusting the retainer. It 's not about "clamping force" It's about geometry. A circle being placed "uniformly" outside of another circle. You have to think 360 degrees with regards to the seal relative to the crank journal. The seal has to be correctly positioned. Not crushed. Too much force on the seal will hasten the demise of the seal, or destroy it outright.
@@victordjinn632 thank you for a great explanation!
When I did my first engine assembly a couple years ago I did my first rear main seal. It didn’t leak. Want to know why? Because Nick walked me through it. And he told me to sand down the retainer ends a bit to ensure I got a good seal. My stuff is far from perfect, but most of my “wins” are because of friends like Nick. Thank you!
Taking notes. Hello Ante.
That's a real nice testimonial there!
So why didn't he do that this time?
Rebuilt a 400 out of a 72 charger a couple years ago with a friend of mine, same problem, we tried 2 Felpros a rope seal and a one piece seal, couldn't cure the leak, after extensive investigation the crank was turned 10 thousands under and we checked the runout of the end of the crank compaired to the main journals and it was 5 thousandth out, hard to get a crank turned true nowadays, they turn the main journals and each end of the crank is off. We put in another crank and it cured the leak! Please check the runout on each end of the crank Nick, I bet it's off. 005 or so.
After I have a crank reground, I measure it on the counter in front of the machinist.
Also, I don't like using a crank after it's been used in a stick shift car.
They always have more end play wear.
That was my first thought, bad Crankshaft, I'd be interested to see what He does
When I'm grinding the mains, I don't even bother indicating the end journals until I get the crank sprocket shaft and rear seal surface under .001" total runout, then I'll indicate the end journals and center journal.
You deserve to have a company sponsor you. You're one fantastic automotive engineer.
Very kind. Thank you.
Now we know the rest of the story, if it continues to leak at the rear seal after turning the crank, shave a little off the seal block. Not something you want to experiment with in your home garage but for someone like Nick "the GREAT" to perform in his shop, because he is professional and knowledgeable with all the years of experience. great to see that K-tools and Atlas lift systems has chosen Nick's Garage to sponsor
Thank you!
Others have made the comment, and let me add my .02 cents to it as well. There are other blogs on RUclips with dyno runs, and it seems they never have problems, or at least no problems that they show to the viewer. NOW, everybody on this blog has worked on engines, and we know for a fact there is no such thing as "no problems" when running an engine that just got rebuilt. I admire Nick for showing when he runs into a problem, and how he solves it. He doesn't hide anything from us, we're there living and sweating out the problems with him. This oil leak on a 383 was a tough thing to work through, but the problem got solved. He showed us that if we hang in there, the solution will come to us. What he did was ask the question, "what got changed on this engine?" and one answer was, "it got line bored." which moved the crank centerline up by a couple thous' of an inch, and that led to the solution to the problem. I respect Nick to a tremendous extent and I'm sure many others are just like me.
What makes a world class mechanic.
Perseverance
When I decide to build an engine.
I'm going to make sure you're the man who does it.
nick you are a genius you figured it out and none of the other mechanics had a clue
I have been waiting for the second part of the 383 video to see if Nick cured the oil leak on the rear main seal. I'm betting on Nick and his 40+ years of engine building experience. What you see is what you get on Nick's Garage the bet channel on RUclips hands down!!! A little late to the party this afternoon.
Thanks for the vote of confidence, sir. Much appreciated. And, we're glad to see you here, no matter when you have time to visit. ❤️
@@NicksGarage I just want to give a big Texas Thank You to Atlas Equipment, and K Tool International for coming on board to sponsor Nick's Garage. You couldn't have picked a better person to sponsor. You guys rock!! From what I have seen in the video their products are first rate, and I would be proud to have them in my own garage. I really enjoyed this video George! I couldn't believe it when I saw the rear main oil seal leaking again, and the devastated look on Nick's face. But Nick's out of the box thinking made sense considering the engine had been aligned bored. I was very happy to see that Nick's fix of taking some material of the bottom of the rear main oil seal solved the oil leak problem. Well done Nick!!!
@@eugenecastles7475 well said Eugene.
Fun to see a victory - it shines all over Nick's face.
Thank you to K Tool! You just sponsored a very good man and his legacy! This is special 😃👍
Thank you, Lee. That is very kind. We are glad you are with us on this big step.
Nick have you thought about using a bore scope to look for the leak gunsmith's use them to see inside the bore of a rifle I think it would be just the ticket to look at the leak from a distance
Hello Mr.Nick!..I had a continuous problem with a rear main leak on my 71 challenger 383.When I went with a after market,Rear main seal retainer my problems stoped.I used a billet seal retainer. After questioning some of my friends who are early Mopar engine overhaulers such as yourself. They told me after countless heat cycles the retainer can become warped, and will no longer seal.Not a common problem, but as you know anything is possible. Keep doing what you are doing, I enjoy every minute of it!
What an emotional rollercoaster on this one! Nick took a step back, put his brain into high gear and Voila, problem solved..
Nick is “The Oracle of Engines.”
Congratulations on the K Tool sponsorship. Very well deserved
Thank you John.
@@JohnRoberts71 Nick your moparman
Mechanic tips that saves time!! Rear main Seal
Before mounting the rebuilt engine in the dyno or in the car and before mounting the gearbox
1. Temporary seal with tape and cover the openings on both valve covers
2. Apply a little air-pressure (just a little pressure!!) in the oil check tube from a air compressor
3. Spray a little soap+water mixture on the rear and front seal, oil-pan, valve cover, front cover and check for leaks
Regards
Peo from Sweden
Mr Nick, I just knew you would sort out the leak. If anyone was going to work it out it would be you. Well done. Cheers🙂
Nick having Atlas and K-Tools being a major supplier to you, is wonderful. Christmas in May. Congratulations!
We could not agree more! Thanks for helping us make them feel welcome at the shop.
That’s what I call a consummate professional, no quit in this man, old school all the way! It’s a very hard quality to find now a days, to many keep throwing parts at it, till they throw their hands up and quit. 👍👌👍👍👍👍
That's computer controlled crap.
Ah that sweet taste of victory after going through the depths of defeat (initially) - been there many times with old mopars
Dr. Nick, your new sponsor has picked the right shop, and well done on the 383, cheers.
Thank you Eric.
I feel Nicks feeling of satisfaction !
There's nothing like solving a problem that's been a real pain in the you know what !!
I'm not a mechanic, I'm a carpenter but take great pleasure in watching another tradesman that knows his stuff share his wealth of knowledge and "tricks of the trade". Not only does he share his experience but also his success! Thank you Nick!
Thanks for watching!
If you take the rear retainer off again try put a dial indicator on the crankshaft on the seal journal, I'm prepared to bet a coffee it's got some knarly runout.
First
thanks, KTools, for sponsorship to one of the last great old school engine builders. Second, I knew Nick could fix it. That's why sponsor him buy it, love it , wear it I do.
Well done Nick ! Glad we were able to share in this triumph with you! Nobidy better !
Hello Nick and your family of workers and to all the fans,,,,, having owned many 383, car's and having worked for Chrysler as a mechanic for them,,,, built many motors and I have yet to have a rear seal leak, except on an engine with a great need for overhaul,,,, I remember one 62, model with over 300,000, miles,it barely leaked at the rear of the engine,, mostly the oil pan,,,,, but there's always a first time for everything,,, good luck Nick.
My good friend bought a 1970 Road Runner. 383 4 speed.....all black. I did some work on it and we raced it at my local drag strip in NJ. Went 13.87 100+ and got a trophy that day. I had zero experience with Mopar engines but it ran pretty well for a big car......The shifter was really long but I never missed a gear.....Slicks and open headers at the track.....street driven....
Nick I had a miserable leaker once . I was able to install a flex plate for an automatic transmission on the engine ,it had lots of big holes in it . Then while it was running I aimed the timing light at it like a flash light . The strobe action allowed me to see through the holes while running
This engine came seen The wizard of Mopar!
Wow how awesome is that!!!!??!? A couple of great new sponsors with some some excellent useful tools and devices that can go right to work for you on the spot!!!
Good on you Nick!!!!😁👍
Big blocks Mopars are great, thank you Nick
Nick just simply refuses to give up until a problem is solved. I have so much respect for you Nick and your talents!
Easy with the engine not in a car.
@@jesse75 , Let’s see you do it all then, smart ass. Start a channel and do exactly what Nick does every day, 12, 14 hour days. Come on let’s see.
Appreciate it !!
Personally, I like the rope seal. I have had very good results with them.
experience and dedication MATTERS the most another awesome job well done nick
The old Mopar rear main leak. Built a few. Always went with the roap style. If done correctly, always worked.
Thank you so much for ATLAS & K TOOL for having the back of such a great wrench and fine man as Nick and his entire crew. His fans will not forget your companies ,I can tell you that for a fact.
Proof to never give up!
A dry pan is a good job done. Get some rest Nick💪
So cool to see the new lifts come into the shop , plus K-Tools for a sponsor!!!! That is great and they couldn't find a more better man then Nick and his shop to sponsor!!!!!!! So many beautiful Muscle Cars in the shop and engines !!! Peace Love & Muscle Cars !!!!!!!!
Thank you kindly, Sarge
I believe the Big Man upstairs cracked a smile when He put Nick to *this* test. As anticipated, Nick did not disappoint. Great video.
...at first I though the camera guy dropped a little oil there as a joke....
Nick, Congrats on the sponsorship and newly
acquired equipment! Well earned with hard work, dedication and tenacity!
I've learned a few things from Nick, but one of the most important has been the advancement of the distributor to get the vehicle to fire off immediately! I've always thought that you need to move it every once in a while. He says to point the rotor at 5pm always... my truck starts right away!
WHAHOOOO!!!!
Would love to see a pistol grip on the dyno console
That is such a cool idea.
Oh, yeah!
Justin Trudeau wont allow it
@@bendover6987 🤣
@@bendover6987 Does he have any authority over anything? Don't bring the clown into a serious discussion please.
This is old school stuff like when me and Nick were growing up doing it by ear.
Old school for the win!
St Nick of the MoPaR!! Well done on the leak and you're patience. Congratulations with Atlas and K Tool sponsorship! The lists look awesome. Great video George 😁👍
Thanks very much, Simon.
The oil leak on the 383 was a bugger, I am glad you showed us how one could fix a leak of our own. Great show, Thank you
very much
Pretty darn impressive numbers since the old 383 magnum was factory rated at 335 hp - I had an old motorhead pal back in the 70's who had an all original 383 magnum in a 69 roadrunner, that was a great running engine and lots of fun with a four speed behind it, lots of torque and tire smoke to be had - though at times it was hard on motor mounts and clutches.
The Australian Made Holden 253 308 and 304 Engines with a rope seal have a machined groove for the rear main seal cut similar to your American big block Mopar, Chrysler 383. The Holden Engines originally had the 2 piece neoprene seal from the small block chevy on earlier models, but then changed to a rope seal. Alot of people have difficulties installing these but, when done correctly "It Won't Leak leak with a Rope Seal".
The only other option would have been casting porosity and I have dealt with it. But when you mentioned the deck height divergence, I thought BINGO! Well played.
Mikel
Really enjoy seeing the 383 on the dyno. Keep up the great work!
In the 70es my dino was the track and my problem solving skills taught to to me who took me under their wing and taught me they didn't have to but they did and I thank them all for it!
Great work on the 383, Nick!! Love the sponsor goodies, well-deserved. Cheers!
Heck yeah mr nick !! Old school is were it’s at !! Really love this show !!
So this is why I kinda like the old rope seals. They're a bit of a pain to install, but they end up beings the "size" they need to be.
They find a way.
Nice save, Nick! I was impressed that you noticed 0.020" change in deck height, and kept wondering, "How's Nick gonna fix this one?"... I thought you'd try a rope seal next, but I like this solution even more. I hope it works for the long term, carry on!
One of those miniature cameras on a long flexible neck (endoscope) which also can be used to inspect cylinders through the spark plug hole would be handy for these things as well.
Great question 🤔Australian 🇦🇺 muscle.Adelaie S.A.
Great work Nic, we were all rooting for you to figure this mystery out! So exciting to see the conclusion of this engine series :)
Congrats Nick! Wow, that is huge to get a company to want you to use their stuff on your channel. That means you are doing something right for sure. Yeah, they get to be seen by a lot of viewers but you get the tools you need and save a ton of money. Win-win. Good for you and the crew. Nice simple solution to the oil leak.
I've been lucky with my cars over the years as I haven't had to deal with oil leaks. My current apartment building has some of the leakiest vehicles I've ever seen, and they're not all junkers. Would drive me nuts if I owned one like them.
The experience and dedication fixed the problem. Another fantastic show Nick and crew thank you.
You're the MAN Nick
Makes sense, especially when the seal retainer doesn't share the same centerline as the crank after line boring. Great fix Nick!
Problem solved and a new sponsor with goodies for you Nick. Awesome!
Thank you!
That is so awesome those company's stepped up for you Nick, Because you have a great channel and should be recognized for it! ALLWAY'S WATCHING💯
Thank you!
I’ve learned quite a bit watching this channel. It takes a ton of skill and experience.
Happy to help!
Those Mopar dual plane intake manifolds look pretty good.
All of us mechanics are the same,,,, we just can't walk away till it's fixed!!
Glad it worked out for you Nick, have an ice cold beer and get some sleep.
YAY K Tool. I will remember you after my garage is done.
I bet the knurling on the crank was to blame initially. You FN did it though! It would have become one of my failed projects in the back. I'd like to see you fix a '96 Park Avenue that the A/C won't change from going from the floor and the defrost. AArgh. Also without a fine lift as you have it's hard to reach for this 'ol man. . I see your determination and am inspired.
About 25 years ago I was working with a GOSS electrician (Newspaper) and suddenly there was a flash that came from an electrical panel that was giving us issues. Surprisingly, everything started working the way it was supposed to do. I asked the GOSS tech what happened, and he said it was FM. I asked him what FM was and he replied: "Fu*king Magic, you don't ask why it happened, and you don't try to figure it out either." Paraphrasing of course!!
I was the Boss of electrician Kobenslauge. 1/2 Germ 1/2 Japanese. Raised in deepest darkest S.W. Florida in Florida, I called him a CrackerJap. He'd smack unruly electronic units, unyielding to diagnosis of the problem(s). I'd say," Don't do that!", ( Like that would have stopped him), but on further experiences, it was sometimes effective! I adopted his approach. Sometimes it would lead us to a concrete solution.
@@eugenetalley7447 This is hacking, doing something that should not be done to make something do what it was not supposed to do or to fix it. This guy had that kind of mind. Big memory about technical stuff, curiosity, able to see it's world and the stuff he was working on in 3D, not just visual 2D.
I did a lot of that on Roland printing presses and twice as much on Royal Zenith Planetas. When all else fails hit it with a wrench and look out!
Great job, it takes a lot out of anyone trying to solve these problems. Sometimes a bit of rest and fresh eyes on the problem helps to solve these things. Well done!
Like Christmas at Nick's Garage!
Sometimes you just have to throw the box out. .020” that was a bit of back and forth. Very glad you figured it out Nick. Hope when I get to the rope seal on my 215, it goes together well. Biggest thing holding me back, the oil pan looks like the one you peeled off of this 383 few episodes ago. 🤯. We’ll get there. Congratulations on the sponsorships. Hi George.
Awesome show I knew from watching your videos if anyone could fix the oil leak it was you Nick good job. And all the new tools and car lifts that should help the shop a lot they are investing in a very awesome shop and a very cool person. Keep them coming and see you Monday
Boatloads of respect to Nick! He shows the successes, as well as the, , , not-so successes!
Ahhh, OK, a MOPAR does NOT incorporate the rear main crank seal in the rear crank main bearing cap like a SB/BB Chevy!!!!
So that block you sanded down was strictly for the rear main oil seal?!?!
Great Job Nick. Love my 4 post lift able to have my three cars all in the 24x32 pole barn at the same time
Great job Nick. Happy for you. Keep on smiling.
Well done Nick just shows that you can"t beat experience!
Thanks for that!
I was watching as the engine was leaking. I’m going Nick put engine oil dye in it! Taking .022 of the seal retainer that genius!
Pretty stout 383. Atlas tool and K tools wow that’s a fantastic sponsor! It’s great advertising for them too. People who watch may inquire about there tools. I like the green tool cart in the dyno room!
Some times you get an engine that will always leak and nothing you do can stop it !
That block could've been cast on a Friday, when they were in a hurry to get the work day over and enjoy the weekend. It could've been cast on a Monday and the weekend could've been a long party one and the guy may've been a bit hungover. Or the block mold could've been on it's last leg and ready to get retired at the end of its life.
Any number of possible reasons why she's a leaky.
We've had them before over the years too. Oh well, like you said. We do the best we can.
Thanks again guys!!!👍
It's about experience, persistence and skill. Well done Nick. Thanks for the great video George
Nick wins again! What did you expect?
Great job Nick, love you have great sponsors. I'm sure it will help you get things done.
We know if Nick can’t fix it, NO one can!! Great job Nick!!!
Such a quirky quick little fix! Wow! Well done Nick! It pays to just stop and sleep on it! Tomorrow is always another day! :) Sometimes the little fixes are the best! It was just one of those engines! LOL!!!
Well deserved Nick! You've got the coolest garage on the internet and the best camera man on the internet too! Awesome job George! Keep up the great work guys :)
Thank you for watching !!
Mood lighting for the 383. Perfect
Sweet! New lifts & tools! That eases the pain of the 383 leak!
Congratulations on the sponsorships and the oil leak!
It's good to have to think outside the box keep ya on your toes. Glad you figured it out
Great job Nick, I was thinking of doing the same thing, but was unsure if it was " proper practice" you proved me right, thanks for the re-insurance, I haven't lost my reasoning on my engine building.
With all the content on RUclips Nick's Garage is some of the best.
I also like Mustie 1, Diesel Creek and Hamiltonville Farms.
They are all grand entertainment for an old guy.
Reoccurring oil leaks can be so frustrating, I think you got it Nick, congratulations on the new lifts and tools 😁👍
That was incredible. I can't believe you found the solution Nick. Speechless to say the least. . .
That's a fine 383 Mopar and you fixed it good.
I have built B blocks since returning from Vietnam, 361,
383 and 440. Never had a a rear seal leak. A friend of mine in Killeen Texas had a shop and went out of business/retired and had a large pile of b blocks, heads cranks cams etc and he gave em to me. I had a 1/2 Chev pickup and took me 9 days hauling. Yes I had adequate MTL for my 63 Dodge bracket car. Yes they were also lots of TF and associated cases and internals.
🎉 good job nick ..nice numbers for a stock 383!
Really enjoyed the show! Thanks guys! Get some sleep Nick!
