Hey guys recently I've been driving around and get the smell of exhaust and maybe antifreeze smell through my heat vents and the car has been blowing white smoke at times and I took it to the local mechanic and he said a few hoses were mixed up when he put the skunk2 intake manifold on and that should fix it. well it did for a little while and now its back and he says its cause I have a dc header and test pipe cand cat back exhaust but I am thinking its my head gasket. Any suggestions?

 

headgasket.

what color is your coolant? dark?

i blew my headgasket, and everything was the same as what you're experiencing

 

its still a bright green that hasn't changed but awhile back my oil was a cappicino color but that has been fixed and its driving me insane wonder if the car is running rich?

 

cappicino color oil = FAIL!! fix that HG before the coolent ends up killing the main bearings and rod bearings then p00f byebye motor. Any kind of water in the oil will kill a motor quick,then you midswell use the short block for a boat anchor.

 

so you think my mechanic is waiting for that to happen so he can milk me for money?

 

It's possible.
Check your oil again and see if it has water/antifreeze in it.

 

Wait so you smell gas through your vents? If it is check your O-rings on all 4 injectors and replace them.

 

do you smell fuel or exhaust? they are two different smells. exhaust smells are usually leaks. fuel could be a host of things. the o rings..however you normally have a vacuum leak if this is the case. a bad o2 will have the car running rich thus creating a heavy exhaust odor.

 

question: whats the problem when you smell gas through the vents?

 

the thought of it being my o2s has crossed my mind cuz at one point a little antifreeze was burnt through the exhaust and could've ruined the sensor on the o2, idk but the car is currently for sale now so have to be figured out by next owner
