It wasn't overheating at all, the smoke continued as I drove (was really bad at acceleration), no CELs, and I'm not losing coolant. Thanks for the help so far

Also it did not smell sweet at all, it was very much the smell of partial combustion, nauseating and odorous

Well a quick test to see if it is fuel, is to look at your catalytic convertors. They should BE RED HOT with that much fuel going in them. That is what they do, they pretty much burn up the extra hydrocrabons before they exit your exhaust. But I am betting that you have a blown headgasket, which is letting oil and coolant go into your cyls.

Thanks

Power steering fluid is leaking through your power steering valve which would be ATF. Check your power steering fluid level. Replace valve.

Hey everybody, an update, that intake repair didn't end solving all my problems, and my car began smoking heavily. I've since taken the head off to do the headgasket and valve stem seals, and it seems that it was indeed a blown HG on cylinder number 6:



Sooo thanks for the help, good diagnoses, and again thanks Joe for the ECU

Bonus pics...my nice clean head (still needs to be milled):

Thanks for the update.... I think mine is blown too, I was looking back, searching headgasket issues and remembered this thread. Your latest post erases the sliver of hope I had that it wasn't my gasket.

Pull your dip stick and see if you smell fuel. Mine did that but not as bad and was an Injector . Also do a compression and leak down test I'm Sorda thinking its a head gasket .

Thats interesting still though, good to know. If I get her all bolted back up and the smoking continues, Ill know where to look next. Do you know how I could check my injectors while I have my intake manifold out?
