Valve Seal Checking Tool for DIYer's.
Valve seal checking tool for DIYer's. Thanks to my buddy T-man and Jafro for the ideas, inspiration and component list! This is such a useful tool and I recommend it to you DIYer's. I already relapped the one cylinders 2 exhaust valves and gained 2" of vacuum, which matched the other 3. This was all bought on Amazon and assembled this morning in about 30 minutes for under $120.00.

Do you have a list of the parts? for this tool?
Hey bud, best way I found with these is to shut the valve and time how long it takes to lose that vacuum. If valve stem seals arent in you can put temporary ones in using a bit of latex tubing cut and slipped over the valve and valve guide. Nice work.

Reason is because these vacuum pumps are powerful they can pull a decent vac on a leaky valve! The pro ones use very small CFM so no need to isolate. But with a pump like this you want to be shutting that valve I think so you can isolate the pump from the system.

Yeah I played around like that too but didn't really "time" them. It was interesting and FUN to check my work. I posted a before and after picture of the #2 cylinders exhaust valves when I got finished with the video and gained 2" of vacuum just lapping a little more. The leak down you are talking about is a good test of the wear of the guides and any bad valve stem seals, which were old on that head. I appreciate the tip and thanks for just tagging along this adventure that seems to repeat itself because I drive pretty dam hard but know who to blame. 😊👍 Also, I intentionally got THE CHEAPEST, LOWEST CFM pump I could find for this experiment. It will double as my vacuum pump for my personal a/c jobs that I have been using a venturi style pneumatic pump for. 😎
Your cutoff valve should be between the pump and the gauge, not the gauge and the head....it. will allow you do the leakdown test.

That's awesome! What's the block?

4G63 running 40lbs of boost in my 1990 Eagle Talon with a HX40 Holset turbo. She is one fun car and a scary one also. Thanks for asking 👍 I should have some pictures up later today of the motor. I am waiting on a good front cover and she is about done!
