Where Did All My Oil Go.?

[mook1]

hey guys. got a r33 gts-t and every time i check the oil its below the low mark.. i dunno if thats a good sign but im guessing not. i last did a oil change 5k ago and since then i have added 1lt of oil and its still below the low marker. its not blowing smoke from what i can tell. its had this problem for a couple of oil changes now, but seems to be getting worse. any one have any idea's.?

i also think i just blew my turbo but yet to confirm that, it makes an awfull grinding noise in high boost so i guessing its F*!@# This just isn't my month.

Ohh yeah besides the noises and oil it still goes hard.

Any advice on either issue would b great.?

Have a leak down test done.

Are you checking the oil on flat ground and once the engine has been stopped for a minute or two?

Are there any bubbles in the radiator? Is the oil milky under the oil cap?

Can you see oil in the intake pipes near the intercooler?

if you said that happened on your LS1 commodore, i would say thats normal

however on your RB, to use oil like that you have a serious problem somewhere.

Goto something not quite right there..

Since I got my car the oil hasn't gone down a mm at all..

i had this same problem, in my case it was ringlands & an engine rebuild. with any luck its your turbo... first thing would be compression/leak down tests, as '3lit3 32' said.

OK first thing i would do is use my EYES... yes that's right. jack it up and have a look. if you suspect turbo problems, oil pissing out of the turbo/everywhere in that are could be a good indication that a seal has blown etc. oir oil line split... If the engine was burning that much oil i'd say it would run like a bag of shit anyway, but you say it is ok..? but if you wanna check the way i have been told by my foreman is ; hold the revs (neutral) at about 3k back off, quickly stab accelerator again.. iff you have blue smoke you have problems, then i would suggest compression check etc.

Now i'm no albert einstein but i'd say looking for the leak first would be the best way to go... come on guys.

Unless he's a complete idiot, I think he would notice an oil patch of the proportions required and, therefore, mentioned it. For it to lose that much oil in 1000 kms and the cause to be a leak from the turbo or lines it would be dripping on the ground fairly heavily. Not to mention the smoke in the engine bay where the oil would be burning on his turbo housing or blowing back onto the manifold.

But then again...I did take for granted that he would check obvious shit first before posting on here. I have made that mistake of assumption before.
