I pulled the head on my '89 Toyota Cresidda and in a moment of ignorance, I laid the head on a wood dolly that had a towel on it valve-side down. Didn't realize at any given time a couple of the valves weren't going to be below the surface of the head. It was laid down gently but for a few minutes it sat that way until I realized this after examining it and started laying it on the side.
Yes, dumbass, ignorant amateur mistake but that's what I did. I advised the shop I took it to, they said they didn't see any obvious problems with any of the valves when they surfaced it, but is there a way to check the valves for leakage - i.e. bentness - myself? I thought about filling the individual chambers with oil and see how rapidly it oozed out, if there was any of them that displayed more obvious leakage than others .
Thoughts, advice?
