How is the center port rich/peripheral ports lean issue on this?

I had several of those but never a need to work on them... Redone a lot of the Chevy 6 cylinders. Using a 230 head milled down and valve job , on a 250 block was a favorite... Don't know but I'm guessing you can't put a 170 head on a 200. Or a 200 head on a 250... ? I wasn't doing it for power , I was doing it , chasing 40 mi per gallon....

Were did you buy your transmission line spacers...

Looks like I am not... the only one. Has anyone replaced vacuum pump? Will that change anything if there no boost?

Can a 4l60 bolt up to this ?

Drunk shopping strikes again lol ;)

I am updating mine to hei distributor. Which one are you using?

Awesome!

My mechanic charged me extra 75$ to remove the freon.

Also, what would the horsepower Be

What would that sell for?

Just got a pair of proforge Taller upper ball joints. For $60 a pop they better be as good as they claim.

What kind of fitting do I need to help the flared end seal

Everything from seed master batter is all JUNK CHINESE Garbage stolen from people that actually know how to design and build real heads

comp cams makes a top end kit with screw in studs ,guide plates ,push rods and i also use the magnum roller tip rockers . ive built three 455 engines using the comp valvetrain parts and im very happy with the results and its easier to purchase all the matching parts than to piece it together hoping the various manufacturers parts will work well together

My pipe has the same movement but no leak at all?

I know this is 3 years old, but this was my problem. I must have pulled a vacuum line off while changing the thermostat housing. Thank you!

I need tork line oil mini cooper

That big boy turns 6500-7k easy. That valvetrain is on point whats that engine making hp and trq?

Dad had a 442 with a mildy done 455. That car would destroy my cousins efi fox...

I bet it’s slow 😒🙄😒🙄😒🙄😒

Heat shield bolts😢.

0.006 valve rock lol that junk 0.0013 too 0.0015 max valve guide ,thats a smoker for sure

to suit Culatas.......enough said, just crap. It's an alloy casting, at what point is a helicoiled thread not expected?

Do you remember the name of the part because I am on rock auto and I do not see a crossover hose?

Red 455? Factory red was high compression.

BUT what are the valve sizes?????????? Oldsmobile used 2.07 inch Intake valves and exhaust was around 1.64 inch if I recall correctly!!! This meant Oldsmobiles had amazing flow!!!

I'll take it!

What kinda car.

Way to go Eric nice 👍

sounds like a healthy half dozen!

Sounds Great! What vacuum reading did you see with the isky cam?

With that cam....what psi is your compression cranking? Thanks. If it goes in car and you ever time it on a dragstrip let me know...thanks.

Ooooooooweee an oldy but goody. Sounds good

Are these the heads you looked over in your last video? I’m looking for a set for my 400 BBo.

Love that sound. I have a mild 350 rocket in my ride. Oldsmobile. Keep them on the road...

Did you install headers while installing motor? From the bottom or the top? What is the difference between 350 and 455 motor mounts?

Good job buddy

Yeah mine went into safe mode after the blow off stopped working so I assumed it’s somewhere along the lines of the boost pipes. I’ve been looking for ages. Thank you very narrowing down where to start looking.

Tell Jeff to get some cotton balls and peppermint oil,mice will relocate!

😭

This is a fantastic video and I am going to check a few things when I get home. I did want to tell you what mine is doing. It’s an R60 and engine light comes on and the turbo kicks off. But if I am running down the road, put the clutch in, and turn the car off and then back on the turbo will start to work again. Any thoughts on that one?? :)

I think you may just saved me from replacing a turbo! I just got a mini s and the guy said the shop told him the turbo was bad, but after looking at the turbo, no shaft play and no wastegate play and wastegate closes with around 7 of vacuum. After looking at the vacuum lines under the manifold, I noticed one of the lines was disconnected, I reinstalled the hose. Still no boost, after finding this video, I realized that the shop or the previous owner has the vacuum lines completely backwards…. 🤦‍♂️ Time to pull the manifold again and fix it. Thanks for posting this video!!!! Must appreciated!

Thanks for the video 👍🏼

yet more reasons to not get a Bimmer. I'm a good wrench and keep thinking 'I could work on it', but like Audi and others, you gotta do catortions for every little issue.

Well you tried to prevent the mess from the supply line lol

My 2003 acura mdx /after long drive over 400 miles ,next morning started up/smell burning,stopped engines and checked noticed burn smell,then re start,but unable to re start,no luck/got new batteries starting up good now got a lot smoke near the alternator battery wire connector.wolla its a bad alternator,notice battery picture on dashboard, but for weeks, there was a maintenance light blinking and disappeared,now I understand why/ cost $340 in a shop my family known,part if i buy at auto zone $79’ hopefully this will help people have the same issue.

But it's not clear which pipe I have to fix in vaccuum tank , which one is in line and which one is out line !

Is this A body car or a G body car with those headers

What engine code was popping on you ? I have a p115C and 115D up on mine. I havent finished taking a look at everything, but Im going to check what have shown here. After a little research, if you hear a small bang and lose all boost, engine light comes on, apparently a hose connected to the intercooler may have popped off. Its under the rad in a tight location and a pain in the butt to get to (have to do it from under the vehicle). Between your video and what else I found I hope that fixes my problem atleast. 2010 r56 is what Im working on fixing.
