Great Video! Is the decompression valve closed at TDC or does it have to be manually closed? I'm getting leakage so not sure if I'm at the wrong mark on the cam gear or?
I'm I hearing this wrong? Or are you adding the letter H to the word "used" ? Lol it's your vision of Will Wheaton....cool whip..it gets me every time :) great videos thx for info and reviews
Can you tell us what leak down tester your using please? The standard ones that use 100 psi, always move piston down when you connect them or are too low pressure. I have two, but they’re both for automotive. I believe the piston doesn’t move in your case because you’re applying the pressure slowly or did you have a way to hold the piston in place at top dead center?
A leak-down test will not check your valve stem seals. It would test your valve seats, but not the seals. If valves were leaking past the seats, the pressure would escape through the intake & exhaust ports on the head before reaching the stem seals. Not writing this to be a dick, just don't want others to think they are testing something that they're not & waste time/money.
I believe his logic is; if it’s not compression related then it must be the seals. If it is compression related then do the rings and cylinder and seals when he pulls the head.
Did your leak down tester have small enough 10mm adapter to seal against the head? The one I bought off amazon won’t thread in but one thread before the adapter is bottoming out before reaching the O ring.
@@ExtremeSportsWannaBes I figured out both leak down testers I bought had too wide of 10mm adapters to seal against the head. Once I got a narrow adapter it worked great.
How did you hold the engine at TDC?
There's a screw on the engine that you take off, take the washer out and reinstall it and that keeps the piston at TDC.

Perfect break down and explanation

Maybe, lol. My mom was from the Midwest so I'm sure I've got some accent that I don't notice 🤷♂️🤔😀

I threaded into the spark plug hole. Sealed great

What kind of oil did you run in your 500?
The stock stuff, Motorex 4t 10w-50
