I have had an annoying oil burning issue that I have chased down to what looks like a few of the inner springs on my roller cam breaking and chewing up the valve guide seals. I have taken off the passenger side valve cover only so far and here is what I found.
In this pic you can see the worn valve guide seal and one of the broken inner springs. Both these seals were firmly on the bottom where they belong. Only one was chewed up. I didn't notice the inner springs were broke until I removed them.
In this pic you can see the other inner springs look good except for the first one the spring is broke and the seal is way up on the valve.
I'm not real sure where to go with this, I am still looking for my cam spec sheet but if I remember right it was an ATR 215/210 roller from Cottons. Motor was assembled with this cam like 8 years ago. The car sat for a long time and only a few thousand mile are on it so far.
I will obviously need to get some new springs and seals but I don't really know what to get for either. The heads are old Champion irons bought in the late 90's. Any thoughts?
