Update: I replaced my spark plug gaskets that were only 6 years old. But I had about 120,000 on them. Yes I drive the truck alot. They didnt leak but were brittle and hard just like the old ones i removed 6 years ago. The valve cover gasket was still supple but it obviously got replaced again. It is surprising but I have to realize I might have to go back and redo some of the stuff I did as a "baseline". 6-8 years ago. Almost like a 2nd baseline. I also redid fan clutch oil which I did 150,000 ago. Things like my oil pump seal are doing well which I did 150,000 ago. But it should be on my raidar. Distributer o ring has oil "film" in the area and should be replaced soon. I have one of the last new oem distributers but it is living on a shelf right now since my original is going strong. But I could put that in.
Trivial question. How often do we need to change the spark plug tube gaskets? Every time valvecover comes off?
I installed new oem about 6 years ago 120,000 miles ago when I did the top end rebuild. Yes I drive it a lot.
No leaking that I have seen but valve cover is comming off and will get some other new gaskets like valve cover, pvc, throttle body and distributer o ring that are all also 6 years old. But I didnt know if I should do the plug tube gaskets again as well.
