So I bought a 07 g35 sedan 6mt and ever since I�ve bought this damn car I�ve had nothing but problems first the ac compresser went out then the car had this weird uncomfortable shake to it my father said probably needs a clutch so he said you can drive it for a few hundred more miles the next day I was just cruising and the whole car was smoking there was a whole puddle of oil underneath the car I shut off the car and got it towed back home just to find out there oil everywhere underneath the car on the tranny the catalytic converter everything and I can�t locate this leak I will upload a few pics.

 

Just start the car and look for the oil leak with an inspection mirror and a flashlight. With that much oil it should be obvious, don't let the crankcase run dry.

 

The thing is that it�s going everywhere people are telling me rear main seal is that common?

 

Let me repeat what I just said.

WHERE EXACTLY is the oil coming from, with that much oil it should be VERY OBVIOUS because it's going to be pouring out of something somewhere.

 

I'm not trying to be an ******* about it but you need to TROUBLESHOOT THE PROBLEM. There's a lot of reasons a car can be dumping a lot of oil.

You could have a hole in the oil filter

You could have a hole in the oil pan

You could have blown a big chunk out of a valve cover gasket

You could have thrown a rod and have literally a hole in the side of the engine

You could have a loose drain plug

You might have a bad RMS?

Get an inspection mirror and a flashlight and look to see EXACTLY where the oil is leaking from. Don't just automatically assume that it could be something, especially not something as labor intensive as a RMS, troubleshoot that ****!

And a loose oil filter or a defective oil filter gasket?

 

Just like I suspected you need up being RMS but now my car is making a weird rattling sound my mechanic is telling me it has rod knock and that I need a new engine. When the car is idling it doesn�t make the sound only when I rev the engine it makes that sound I suspect the catalytic converter or heat shield anyone else have this problem?

 

Take a video of it with the hood open and try to get a good capture of it making the sound.

Rod knock is pretty unmistakable and you can usually tell from a video.

 

Why did you purchase the vehicle without having it inspected by an Infiniti dealer?
