Hi all,


I took my cylinder head out and had it resurfaced at a machine shop. The machinist did a pressure test and mentioned that the valved are in good condition and don't need a valve job and so the head just got resurfaced.

I took it back home and spent sometime cleaning up the head at where the intake and exhaust ports are...and used some brake cleaner to clean off the carbon. I noticed that one of the exhaust valves was leaking the brake cleaner while all others seemed to have a tight seal.

This is rather obvious of a valve problem?!, but does it mean I definitely need a valve job and should have taken it back to the machine shop for a complete valve job?

Thanks.
