Yes, but they're still bigger than the RB20 portsCjmartz2k wrote:?? RB25de's had VCT also. You mean this is an early RB25de head out of an R32? I know those didn't. The ports on the head were smaller too on those.
Yes. I've since spoke to a machine shop, and several of my other buddies who build domestic engines and they say getting some, if not lots, of metal particles at the beginning of a rebuild is normal, like Carl mentioned.Cjmartz2k wrote:Intersting......
Post some pics of the oil when you change it. are the metal flakes coming out magnetic?
I've actually got two friends over here that have spun main bearings in GTR's from trying to gymkhana them. Crappy oil pan design gets all the oil stuck away from the pick up, sucks dry, spun main (#1 both cases)Carl H wrote:a dyno is a better way to do that then to sit on the car...just sayin lol.
never really heard of nissans spinning main bearings, this isnt a DSM car.
have you ruled out the possiblity that something is hitting once underload?
my wastegate dump tube would randomly rap against the frame rail under load but loosening and pushing it over some solved the problem.
That's actually awesome news man. Congrats. Now about your shop mistaking that sound for rod knock................ST240 wrote:You guys are going to hate me.
Lol.
I decided to check the wastegate. After I disconnected the wastegate, that changed where the sound was heard. Upon closer in-f**king-spection, I noticed the turbo inlet flange was loose! My god.
Its been emotional.
