Help! Is my head gasket blown?
As Tom and Ray Magliozzi, better known as "Click & Clack" the Tappet Brothers of Car Talk would have put it: "The mechanic must have had a boat payment coming up" or in this case several boat payments.
getting heat/cooling system to work properly is a bitch from hell on infiniti..........mechanic has done everything but shoot it with a .50mm Barrett weapon................now we think may be a head gasket......K seal in it now and so far so good
Man I have the same situation with my G coupe. The same day I bought it there was an issue already happening. I went to put gas in the, drove off and five minutes later the car shakes like crazy during low speeds and stopped twice at a red light. Smoke came out of the passengers corner side of the engine. And after I added some more coolant, light white smoke started comming out of the exhaust. Mechanic said it's just coil pack/ sparks but I think it's the HG.
Well the conclusion to this matter was a $4,300 bill from garage. I personally think the garage (Who has good reviews) raked me over the coals. I was originally quoted $3,200 for the overhaul but there were "other" things that needed to be replaced (water pump, extra gaskets, hoses, and catalatic coverter had some holes in it) The motor of course runs great and seems to have all the power. (I think it should I could have replaced whole motor for this price). The guy who sold me the car gave me $1,000 and says he would get me more later (Anyone besides me think he will?) Grateful for the help he gave but still with this amount of money I could have bought a nice 2008! Oh well the moral of this story is that I will never buy another used car without a mechanic close by giving it a go over even if it cost me a couple hundred bucks its better than thousands.

If he (mech) went factory Cats, there $%^&ing expensive. And if it has been pumping heavy antifreeze vopor through it for any length of time it would not shock me they were eatan all to hell.
The rest of your bill is labor.. taking the heads off for someone super efficient is something like 5 hours .. having to refurb them adds on.
yeah in hindsight, once you heard 3200$ ... it aint much of a stretch to go for along block.

Because all the symptoms that happened to my G pretty much relates to a HG issue based on the research I've done in the forums/threads. But I'm praying that's not the case, if the mechanic was working from Nissan/Infiniti I'd be more optimistic about it but idk who the mechanic is all I know is that I towed it back to the dealer so he can fix it and the dealer brought it to a mechanic. Benefits of a warranty I guess
