Well, I worked in an auto machine shop for a while. So I'm familiar with heads. Although they were big block v8's, not that it's like comparing blue to green or anything.
I know I would at the very least need a valve spring compressor. However, Doing it with out removing the heads sounds......very intriguing.
I'll have to do some sleuthing around google I see.
They make fittings you put in the sparkplug hole that connect to compressed air. The air pressue holds the valves shut. You have to have a stud mounted spring compressor though. Pretty easy to do, it just takes time.

yup a simple cylinder leak detector can be used to pressurize the combustion chamber , but you gotta watch the pressure and be quick , because i can see that pressure slowly escaping thru the piston rings....

What does it matter if you are quick or not? Pressure is always blowing by the rings. What would compressed air hurt anything?

he's worried that if you're not fast enough the pressure will drop and the valves will fall into the cylinder and then you're up shit creek

Ahhhh, Ok. Guess you better be using a big compressor then, OR better yet, HOPE you dont have a lot of leakdown LOL

I hate to go against advice of people I trust and respect but I went ahead and bought those seals after researching Viton. If it comes back to bite me I'll post the info.
