Cylinder #7 down on compression
Happy to report i did a wet leakdown test on a few cylinders and they all held fluid overnight. #5 being one of them.I've had the car for more than 8 years and know now the engine is .30 over with cylinder walls that look like they were machined a week ago. Both heads are now at a local machine shop and I even took my manifolds o be sandblasted and powder coated. It was recommended to me to go with thinner head gaskets. The ones that were on my car , Felpro 8553' are like $14 a piece. Cometic .27 are $98 a piece....Thats a **** ton of a difference. Would it be worth it?
Really happy to hear. Now you know the rings aren't washing that piston head.
That will tell him absolutely ZERO regarding ring seal since they have gaps. They are not made to HOLD fluid or pressure for any length of time past the explosion of combustion. The results will mean not one thing.
It's a comparison between cylinders, if all but one hold fluid for a reasonable amount of time while one drains in 10 mins, as I have seen many times, that's significant.
It's a tool, Rusty, - and of course, like many tools, if you don't know about it, it's of no use to you.
It's your untested opinion, vs my tested one, which was passed on to me, and I have passed on to you and others.
Nothin worse than doing a valve grind on a vehicle, have it come back a few months later running shitty, puffing smoke cuz you didn't know a way to test rings, when a leak down test had leaks everywhere.
A splash of solvent in cyls, a few seconds, while scraping gaskets.
The things you learn from mentors and on the job, - - experience .
