Changed oil today and noticed bronze metal shavings in the oil!! 2005 g35 30k miles ...

 

You been hittin the rev limiter alot lately? only thing I can think of that's bronze is the valve guides.....but if the metal was burned, then it could be anything.

Metal shaving is normal in a new motor.....you kinda have me scratchin my head now.

 

I have 30k on the car i find it strange for metal to be in the oil . i hope its not my bearings!

 

yea, saw your mileage....that's what makes me scratch my head....new motors its normal.

Save em and take it to the dealer....maybe you can get a new motor if it turns out to be your bearings. If you're heavily modded, you might be SOL.

 

Sounds like you are getting ready to shoot a rod through your block. If you are modded take them all off (includes intake, valve cover even different caps). Warranty will void you for whatever they possibly can. I had metal in a my pan on a few cars and boy oh boy talk about bad news!

 

Take a sample and send it to Blackstone Labs N-O-W!

 

Bronze? What in the engine would be bronze Silly question, but if you have a 6MT, are you sure you sure you drained the engine oil and not the transmission oil?

 

DaveO I mean DaveB, I think bronze is used under the top coat of the crank/rod bearings.

 

Metal shavings? OOoOHHHhH Damnnn, i think you might be running metal against metal and most likely is the bearings, same thing happened to my F-150. Better return to stock ASAP and take the car to the dealer and if they repair it, you need to re-evalute what mods you have and what they are doing to the engine....30K miles is wayyyy to early to be having those type of problems....keep us updated!

 

wow that is crappy def bring it in to the dealer

 

Very strange. If it's bad enough to see chunks of metal, you should have been hearing unusual things under the hood. Especially upon startup.

Any low clunk or knock that repeats every half second or so when you start in the morning? Ever overheat or have the oil light come on? Did you notice this upon draining it or was it on the dipstick or something? If upon drain, cut open the oil filter and see what is in there. That will tell you a lot.

 

My guess they were metal shaving, but looked bronze because of the oil coating them.

 

Rod and main bearings have a high amount of tin in them. Bronze metal in the oil would make me think of the thrust plates, washers behind the cam sprockets. If the camshafts are walking around in the block this would be the cause. Still very scary finding metal in the oil. You could find that in the transmission very easy.

 

Has anyone inspected the timing chain tensioner. Could it be brass or bronze?

 

Nissan has traditionally used plastics for the tensionor guides and for the end of the tensioner itself. But I haven't seen one for the VQ35 specifically
