I have a pair of GM performance chrome valve covers and they take the push in style oil fill cap. I have tried several different caps, each one fits tightly at first but after a week or so it gets loose enough to just fall out. Has anyone else had this problem?

 

i did not have that problem yet. i went to the store and there like we dont carry ones like those and the stupid guy told me to cut my valve covers, i was like hell no, and found one that was way too big but for it and noticed that there was a sleve of rubber and if i took that off it would fit perfect so i got it and cut the sleve off and it fit perfect and never gave me a problem yet.

 

Has anybody else had this problem?
