    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.

    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"

      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. (-;

    • @goldsgarage8236
      @goldsgarage8236  3 дня назад

      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

    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.

    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

      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?

    • @flinch622
      @flinch622 4 дня назад +1

      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.
