I had my headgasket go on my 4runner.
Sooooo I replaced head gasket and installed a new head becuase of issues with the exhaust manifold holes on old head. Truck is driving fine, but the exhaust smells pretty bad. I cannot place what kind of smell. Just smells like something is burning, not antifreeze, doesnt really smell like oil. Just cant place it.
I did take the cat converter off because i though the issue was originally a clogged cat. Anyway, my question is with the removal of the cat, did the cat converter scrub away alot of exhaust odors when installed? I am not blowing any smoke, nor have any engine codes. Truck drives fine, just smells at times. I cleaned the outside of the motor but that didnt clear up the problem. Just trying to find the stink on my rig.

Thanks

 

thats probably just because of no converter.it typical.

 

I may have found the problem. or a contributer. I went to look and saw i was dripping oil. Was scared it may ahve been head gasket. Looked around and my frickin oil sending unit is leaking oil. I turned the engine on and drip drip drip coming from it. Never seen that before.
