Weird smell???
So basically I get this weird smell that's smells like freshly cut grass but slightly pungent. It happens only after I've been driving my car for a couple hours. And just before it starts I get that egg smell ( catalytic converter smell ) and it becomes consistent then that weird smell starts. No smoke, no lights on dash. The smell IS in fact coming out of my exhaust too as well as thru my vents. Smells around my engine block too I think but not completely positive. Background info that might be relevant, I had an oil filter gasket leak and the oil sat on everything under my hood for about 6 months (I know stupid) and i got it replaced professionally and had my tensions and pulleys replaced. Also when I'm driving for not 2 hours it works just fine!! No smells no nothing. Maybe a small egg smell rarely if I punch the gas really hard but still not every time like 1/20 times I punch the gas (I drive a lil reckless) so I punch the gas a lot. My mechanic friend said to put some fuel injector cleaner in and see if it still does it (he said it probably will) but he also said the only real way to figure out what's wrong is to wait til it gets a lil worse and throws a light

I believe your evaporator has a leak. It's located under the dash. Coolant has a very distinct smell, sort of a pungent sweet smell.
Any good shop should be able to diagnosis it. |

If you trust these 'mechanics' then why turn to the internet for advice?
Personally, I feel these mechanics are not worth a shit. Find better ones. And the comment about it possibly being a heater core leak (not evaporator, that is for the A/C system) could be spot on. It might just be a pinhole and it'd take some time for pressure to build and it to spray and smell. When you do get the smell next, park the car, running, and see if a puddle develops under the car. If it's the heater core it should run out the drain and make a puddle of coolant. But could also be a pinhole in the radiator. Generally though that will be more noticeable, smoke and such. |

Correct, I meant to say heater core. Of course, the evaporator could have a leak too, but then the A/C would slowly die.
Also seafoam in the oil will do a good job of loosening up all the sludge and moving it around to places you don't want it. Can I say catastrophic engine failure? BTW, just why do you have any sludge to begin with? Using a synthetic oil even if it isn't changed that often, will keep the inners of your engine clean. |

Look why are you here bothering us? Just take the advice of those "mechanics". After all they certainly have more expertise than any of us could ever possibly hope for!
