So i bought this sc300 last week for 3k with 270k on speedo but he got a different cluster so he says it really has around 180 but thats not my problem. When ever i drive the car for a long period of time or rev it high theres this bad burning smell...could be oil because i found a leak on my garage floor and ill raise the car to find it but i need help and ohh theres a rattle noise after i go in reverse duper stumped on that but please help.

 

What does the bad burning smell actually smell like

 

Like burning oil and i just changed the oil and oil filter and its not coming from the head either :/ its bugging me

 

What "leak" did you find on your garage floor? Motor oil? Transmission oil? Power steering fluid? ...etc. That should help determine the issue a little bit more.

Oil pan leaks but wont give a burning smell. Valve cover gaskets leak as well.

 

It was golden so motor oil i suppose and what could the smell be? Oil pump? Gas filter? Its only high revs

 

Start by tracking down the leak. The burning is likely from the leak hitting something hot and burning. While its sitting whatever is leaking probably just drips till it hits the ground. Also what to you is high revs

 

Hmm..ok and around 5k

 

By the way my car is lowered a lot lol this is my semi daily car and drift car

 

Standard or auto?

 

Standard

 

Ok the leaking oil went away for some reason but the smell is still there
