intake/exhaust valve appearance?
I just pulled of the intake/exhaust manifolds to weld up some holes in the header and was noticing the valve stem appearance. What should they look like on an engine that has about 100k? It doesn't burn excessive oil and runs fine, just curious about what they should look like. This is on a 258 I-6 by the way. The exhaust valve stems look yellowish tan, and the intakes look black and oily looking? The intakes look like they have some oily/grimmy buildup on them. How can I clean them off? Can I just spray a degreaser on them and then crank it out the engine? Or is there a better method to do this? Thanks in advance for any help!
