370Z oil consumption

zilent_jay · 05-21-2010, 04:13 PM

Just when I thought I was in the clear after the engine swap... (1200 miles)

Driving home from work... I notice smoke coming from under the car. Since I was a mile from my house I came home to check it out. The underside of the engine is covered in oil, and this is what the engine bay looks like:

Lucky me!!!!!!!!!!!!!!!!!!!!!!!!!!!!

What is Nissan's measuring stick for excessive oil consumption? Is it X mm on the dip stick per 1000 miles,etc?

Unlike some manufacturers, it is not documented in writing.... Seems guys who have had a consumption test done and are burning MORE than a quart per Thousand are in line for new engines....

I just got my car back after having the longblock changed out. It was consuming about 1.5 qts every 1000 or so. It feels so much different now!! Just be patient with the dealerships and everything should work itself out.

So it looks as if the OIL SPEWING issue was a result of a damaged part, probably in shipping/installation of the replacement longblock. I think he called it a intake valve timing solenoid... it sits right there on the front of the engine... they actually let me in the shop (thought that was an insurance liability, but I'm not complaining).... every time the guy revved the engine oil would shoot out.... directly onto the belt.... which in turn flung oil everywhere... even the inside of my tires are coated in oil along with the entire engine bay...

The guys at the service department have been really great in taking care of me.... not a single complaint there. But... that doesn't change the fact my car ONCE AGAIN.... is sitting at a ******* dealership with no part availability and no ETA while I'm making payments on a $35,000 PAPERWEIGHT.

Irritated.

Sorry to hear about your oil issues Zilent_Jay I hope they get it back to you completely fixed in a timely manner.

I posted earlier that my Z also consumes what some would say is a ok amount of oil 1qt 3-4k. So I decided to check my 2008 Trail Blazer SS (LS2 Corvette motor) and guess what seems to have lost a 1qt it has been 4k miles since the last oil change. So got the oil changed yesterday and transmission fluid it just hit 50k miles. I will be watching the TBSS now to ensure it has the proper amount of oil in it at all times. I did some more searching and it’s not uncommon for the LS2 engines to consume 1qt every 3-5k or so. And people have suggested if you really get on your vehicle a lot then you can bet it will consume a bit of oil. I wonder if the high compression of these engines has something to do with it. Or it is possible every car I owned consumed some oil just never checked those vehicles to know if that was the case.

How did you get that much oil sprayed around the engine bay? Source?

By the time I got it to the dealer (3 miles) it was even worse... I didn't have my camera with me or I would have taken pictures... the insides of my front tires were coated in oil....

I think the guy called it a intake valve timing solenoid.... it's a little part on the front of the engine that controls the timing and is oil actuated... every time you step on the gas... (wouldn't do it at an idle) oil would spray onto the nearby belt and get flung all over the place.... the part was physically damaged at some point because you could wiggle it around freely... my guess is it happened during shipping/handling of the replacement long block. The guy who did the install did a fantastic job otherwise and I don't think he had anything to do with it... the problem wasn't present/obvious directly after the swap... Coincidentally, it started directly after the point I started revving to 5k instead of 4k during the break-in process. Once I felt the motor start to loosen up my plan was to work it at 5k for a while and then get the oil changed before going all out. Guess I get my oil change now.
