Pics.. are my valves bad?

Post by RockyMtn96XJ »

This is a Pic of before lapping, then after about 1 minute of lap with purple tube permatex valve grinding compound, and a final lapping on a non-pitted valve.
Half my valves have "spots" as I like to call them. Makes me feel better than saying "pits".

Maybe these are toast to the point I've not come across this amount of toastness....

Verdict?

Wow .... I didn't realize how much my old flip phone camera could really bring out the texture in my photos. I call that either bad, or a shart ton of "buildup deposit crap" that needs to come off.

If you're doing a budget build, get a machine shop to reface them. There will still be visible pits, but you may get sufficient sealing. Of course the right answer is to replace them. Either way, I suggest having a machine shop reface the seats in the head for proper seal.
