ask that friend if he has ever heard of a thing called piston slapjdmsr20 said:i hear an annoying sound comin out... i thought it was pistons but my same friend said pistons can never be heard. so he said it it could be my cam gears BUT .... i learned it had cam chains... never heard of that. when and how do i change/upgrade chains? are there performance parts like the cam gears???
From the SE-R.Netjdmsr20 said:i don't know lowport or highport...
The Nissan Primera (Infinity G20 here in the US) has the same motor ,SR20DE, but with (so I have been told)higher compression pistons 10:1 vs 9.5:1.and what is a primera engine?
Like I mentioned before, someone could have replaced the valve cover with an Ininiti one.my engine has a nissan valve cover but marked with "inifiniti g20" because it was replaced. and i believe da noise is comin from the chain area.
