yeah they are LT4 Vette, but I just notice more when I use GC 0w30. I know that ordering AMSoil is easy doing it online but its really expensive plus shipping. Trying to pay same as I do with GC
well the valvetrain noise has some or alot to do with LongTube headers and cam(918 comp cam springs to go along). I just seem to notice the noise more with the GC oil.
Whats up guys?! Ive been using the GC 0w30 oil in my LS1 Camaro, but it tends to have a lil more valvetrain noise when i use it. I was wondering what other oils would be better to use to eliminate the extra noise. I would rather stay away from the Royal Purple or AMSoil simply b/c i dont want to...
