I bought a cheap bore scope off amazon. just under $150. let's me see into the cylinders to see the condition of the top of the pistons, I can stick it down the intake to look at the intake valves, and to better examine the valves up close. you can pull the distributer and insert the bore scope to look at the cam and lifters, and you can drain the oil and put the scope up in the pan and look at the rods and mains to see if there is any color change (bluing) on the bottoms of the rods. or look for broke main caps. I have also used it to look inside manual transmissions, and differentials. it also saved my wallet when I accidently dropped a carburetor nut down an intake port since it comes with a magnetic tip you can attach to it. I highly recommend one, I have also used it to look a brake pad without taking the wheels off, and up under the dash to find squeaks and rattles and to look into gas tanks to see if they are rusty or if they still have gas in them.
They have an understanding, hey if this is real bad it isn’t worth fixing because I have an alternative, or fix it but no reason to give it any extra. People have different ways of expressing have a budget.
Thanks Billy, no that's my fault for not expressing it properly. All my customer asked for was to diagnose the problem and estimate the fix. i just didn't want to spend too much on the estimate if it might be a minor problem. Turns out it wasn't. AG
Nice. The new borescope inspection cameras are really cool - especially the ones that give you side view. You can look at the valves, cylinder walls etc. via the spark plug hole and see how they're doing. Also an oil filter cutter is a must for any shop.
292 "Turbo" heads were Chevrolet's first race heads dating to the 1970's, notice the lack of the heat crossover to the intake. I had a couple of pairs of them at one point and used them drag racing, although they were intended originally for NASCAR they found their way into all kinds of race cars, especially those required to use cast iron heads. The angle plugs required some tool hacking to install and remove with most headers. One would not normally expect them to be used on a street engine, but probably four or so decades past their prime anything is possible in a mix and match SBC. Bill Little could probably fill you in on the pluses and minuses of those castings. (-;
Thanks Marcus. It also looks like they have been ported some anyway. Angle plugs can be a problem, sometimes you need "shorty" spark plugs which are expensive. AG
Thanks John, well the engine is disassembled and i can tell you that its not a wrist pin anyway. I have made a follow up video, next in the series. It should be published soon.AG
The first thing I noticed was the crappy orange oil filter, but then I saw that the oil pan has been off not long ago.. someone has already been in there. It has been 30 years since I saw a set of 292's, but just last week I saw a set of 492 angle plug heads, on my uncles 62 Impala which I restored for him.😉
with 40% leakage you may listen where the air is going could be something under a valve or broken valve spring may be a bent valve or at lest point you where to look first top or bottom or both. I enjoy your channel.
Thanks Walter, pretty sure it is all going into the pan. i have already disassembled the engine and made a follow up video, it should be published soon. AG
I am really looking forward to seeing the teardown video. I completely understand not wanting to pay for a full inspection but putting eyes on the internals is the only way to know for sure what all is going on.
Thanks Ronnie, the initiative to minimize the tear down was mine, not the customers. I was just hoping to find something minor and save a big repair. It is disassembled now and the second video will be published soon.AG
it has been determined there is a nose running could make it unrepairable. I was working in a shop a corvetet came in with a ticking noise bbc 427ci while we where listening it dropped a valve took out the block one head hindsight being 20-20 we should have stopped removed the valve covers and found a broken valve spring easy fix, not so much after that. $$$$ I see that more often the not.thanks
It will be interesting to see what you find. Btw, did you get to see #7 blast furnace? I was a mechanic @ 5 boiler House, expander turbine and pollution control?
Thanks Greg. Are you referring to #7 at Algoma Steel? I have been to the top of it many times, it is one of the tallest, 316" to the bleeder deck, as I recall. The elevator goes about half way. I also spent a few Christmas days on it trying to get it running again. Why did we have down days on Christmas eve? I have also been in the boiler room many times, once during a black out. Thanks for bringing back the memories. AG
I’d be interested in seeing the spark plugs out of each cylinder. Maybe detonation is the culprit? Was it knocking, or detonating?? Can detonation also not affect the connecting rods from the heat?
Well, a knock isn't someone selling amway - that much we can be sure of. Forgive me, but I couldn't help but have a little fun since teardown is yet to happen. Just for the heck of it, I am guessing we have a damaged piston and the rod bearing spun on account of initial event. A valve getting tulip'd is going to seal poorly, but the knock is something else. The 4/6 pairing of leakdown results? Head gasket inspection time - #4 just maybe got hydro'd and lands are partially busted out.
Thanks for watching and commenting guys. The spark plugs were gone when i received the engine, so i never saw them. I have since disassembled the engine and made a follow up video, it should be published soon.AG
Every small block anyone has ever tried to sell me have all come out of a Corvette!! ROFLMFAO!!
Thanks for watching and commenting Patrick. AG

Thanks Shadvan, i have one also, but i didn't think to use it on this job.AG
You don't want customers that say "do it as cheap as you can". What they are really saying is "I want something for nothing"
Exactly! Cheap skates

Thanks Jeffrey, just trying to capture the moment and keep the ball rolling while Alex is away.AG
I'm gonna use my crystal ball @ 2:10. Gonna be a broken skirt. I hear peeps forever tell me "It's A Writspin" -It;s Never a wristpin.
Thanks John, well the engine is disassembled and i can tell you that its not a wrist pin anyway. I have made a follow up video, next in the series. It should be published soon.AG
@@goldsgarage8236 Can't wait- BTW. It's Almost Never a wristpin. Just like "carburetor problems" - Most times Thats "Dirt Problems" !!

Getting a reading of 5% is normal if it has gapless piston rings which could be purchased for your engine from Total Seal Piston Rings !
Good info, thanks John.AG
Maybe it has forged pistons in it, they will knock till the engine warms up
Good point Doug. They sure do. Watch for the second video int eh series coming soon.AG
Hey up mate this is going to make for an interesting strip down
Thanks John, the second video is recorded already, it should be published soon.AG
@goldsgarage8236 sweet looking forward to seeing your findings
Cool ! Thanks man!
Thanks for commenting Bill.AG
Strip it completely and actually see what it needs.
Someone has already had a ‘play’ with it noting the difference in color of sump to engine.
thanks Big Al. Yes it is stripped now and the second in a series of videos will be published soon. AG

Thanks Gordon, that is a heartbreaking story. Lesson learned but "experience is expensive." AG
My guess is seized/stuck piston rings and stiff wrist pin
Good guess Ronnie. Watch for the second video.AG

Interesting. Want to hear the knock.
Thanks Speed, I didn't get to hear it myself, the engine is disassembled. The next video will be published soon.AG
Maybe a cracked flex plate. Be the cheapest fix. Fingers crossed 🤞
Thanks Eric, No, not a flex plate. I have disassembled the engine and made the next video in the series. It should be published soon.AG
@goldsgarage8236 I can't wait!!
It’s a knurled piston, lol. Let’s watch.
Thanks Doomman, The engine is now disassembled and I have made a follow up video. it should be published soon.AG
Something tells me you have 2 separate problems with this engine.
Thanks Steve, you could be right. The next video will be published soon.AG
Them exhaust ports look like someone has opened them up a little bit. Maybe stock?
Thanks Jeffrey. Yes, i think you are correct, you can see right into the valves. AG
😊💪🏽
Thanks Paul.AG

I have a pair of them heads
I have a set I ported in the 80’s I dug one out recently and took pictures, I sent it to AG Facebook
Just bought a set of those heads this summer
I'm sorry! lol
