Thanks for the second opinion my nephew feels the same way. He thinks its a multitude of leaks like the flex pipe flange, and the cross pipe I think he called it which was near the EGR valve and of course the EGR valve line leaking. All that he thinks would have made the symptoms of a leaking manifold.

I am still p*ssed that the garage would tell me "You'll feel air in that area". I was like REALLY its a sealed exhaust system or its supposed to be why and how would I feel air in there? Then he tells me "Well I mean heat". LOL Yeah big difference there. Needless to say I won't be back to that garage now that it has changed hands. I don't deal with people that are crooked like that.

Plus my PCV valve is not sealing because of the rubber O-ring being worn out. So I bought the kit from Autozone and its supposed to be in I think they said tomorrow. So I'll get that changed out and see if that maybe helps my gas mileage.

My nephew said the fuel trim data showed that it was dumping a little excess fuel into the system and he's not sure why but that it might be from that PCV valve not sealing.

Might need to use some PB blaster on the crossover also. Just a heads up.

Technically speaking there's still LH and RH exhaust manifolds on FWD applications.. but I'm not going to start an argument.

LH would be front and RH would be rear. I have to deal with stuff like that at work all the time. They don't list parts by front or rear but most of the time the parts department knows what you're talking about.

I understand what you're saying, it's easier to call them front and back with a FWD car though IMO. Since the engine is mounted transversely and all that jazz. Thanks for bringing that point up though.

I noticed in looking at them they were labeling them "RH" and "LH".

Thanks for all the advice guys.

Watsup so I'm trying to do something similar i want to swap a header set and want to change my rusted bolts. Anyone one where I can pick up a set of bolts or what there called? In having trouble finding them online or part stores and I'm trying to avoid going to the dealer that quoted me 62$
