Bad Head Gasket or PCV issue?
Bad Head Gasket or PCV issue?
Well I'm pretty sick to my stomach, but I'm not positive and need input. Bad head gasket, or could this be a PCV issue? 05 Limited coupe, 55k miles. As you guys know I've been working for a long time trying to get all the quirks out of my crossfire and get it back to decent shape... just when I think its finally done... This morning I happened to check my radiator cap and its covered in a milky substance, I have no signs of a bad head gasket from what I can understand. I just changed my oil no milky substance, no milky substance around oil cap etc eveything looked normal. The car does not overheat or loose radiator coolant, and when it is up to operating temperature there is no smoke out of the exhaust. If I remember correctly I did a radiator flush & fluid exchange last year and don't remember seeing this. I know its coming back fast because I just wiped off the cap and reinstalled. Any suggestions?

Re: Bad Head Gasket or PCV issue?
From what I understand, you don't really know the history of the car. If it were me, I'd flush the system once or twice more. I'd use distilled water, GALLONS of it. Then, the third time, I'd add distilled water and coolant and see if it comes back. Perhaps there is contamination from a past 'incident' and all ya gotta do is flush/clean it out.
I sure hope thats what it is. Is the oil looking OK? If it looks ok, seems to be it's something with the cooling system, but if the oil is contaminated, then I'd think about a head gasket, etc. a
I dont know how else to deal with it.

It's an automatic and It's funny you say that because I was suspecting the same thing.. There is zero milk substance inside or on the oil cap.

Re: Bad Head Gasket or PCV issue?
Yeah that's a no go on the cars history I just know it came from FL. I'll go head and flush the system again and see if this happens I sure hope that's what it is to pizza... yes the oil came out how it typically does a hair dirty but other then that no milky substance at all decent viscosity.. thanks for the reply
Re: Bad Head Gasket or PCV issue?
Yeah true I should probably get around to doing that I’ve just done some much general maintenance that everything’s taken care of so I never bothered.

Sorry to hear that what a nightmare. Yeah at this point my stomach is in a knot wondering what it is, hard to believe at 55k it’s a head gasket but I’m leaning towards tranny oil, it’s hard to tell but I’m not losing oil, and I’m not losing coolent, I’m not over heating there’s no milky substance in oil. I guess at this point I’m going to try and do a flush again as pizza suggests and go from there, not getting my hopes up because if I remember this was already done last year, say it is an internal leak somewhere in the tranny cooler I just replace the whole radiator?
Re: Bad Head Gasket or PCV issue?
Just did a transmission flush a week ago but looks like this is my only option.
Re: Bad Head Gasket or PCV issue?
TIP: The one time use cap that covers the trans fill tube CAN be use over and over again. The trick is to snap off the rectangular piece on the top of the cap and then use a small screwdriver or whatever and push the remaining part of the “lock” down through the cap. Keep the “lock” part, yer gonna reuse it.
