Wow - No one with advise !!. Well a friend has suggested I seafoam the valves. Anyone agree on this? Any advise on how to do it right. ? will it clean out the exhaust valves?

Sea foam is an awesome cleaner. I use it every oil change in all my cars (2 currently) and it works great. search the org for it and you'll find your answer.

What makes you think it's sticky valves? What does it do? When I had carboned valves on my MR2 that caused pinging, the only thing that worked was Chevron Techron engine deposit cleaner.

I thought seafoam did exactly that - remove carbon from the valves. Same problem , pinging and high nox - after cleaning out the totaly blocked egr tube and egr. given the amount of carbon there I am sure my valves have a bunch of carbon too.

I would try auto-rx. Most people on BITOG recommend it highly It is also safer to use than seafoam. I've also read mixed reviews on seafoam.

I've never heard of seafoam but the oldschool way to do it is to drip water in the intake in short intervals and it will steam clean the cylinder and/or valves.
