I have been looking for a vacuum for awhile and this one is hard to find.
Any idea as to why the 2 plugs on 5 & 6 are the only ones getting build up?
The other 4 look great?
Yes, the new plugs get gummed up pretty quick.
The thing is it is not burning any oil, I thought it might be burning coolant,but after replacing the valve seals it no longer has any smoke on start up.
I will check again for vacuum leaks this weekend
