hey guys, i have an r32 gtr thats always run well, that is untill now.
i started it this morning to move it out of the driveway and theres a massive knock coming from what sounds like the top end.
it gets faster if you increase the revs and sometimes seems to go quieter for a second or two.
the car seems to run fine still, although i havnt gone out and flawed it because that could only make things worse.
i thought it could be a valve, a spring or a lifter but im not sure.
the car is very stock, still with airbox and all. no boost or turbo work.
ive searched for a while and havnt come across anything usefull too.
any help would be greatly appreciated!!
ill record what it sounds like and post it also.
thanks heaps guys!
