Hey, I think my headgasket is blown. Please confirm anyone. White smoke coming out of tailpipe, eating coolant, it bubbles if I dont put the cap on.

When I start the car it feels like it missfires for 2-3 second and then runs normal. After I shut it off smoke is still coming from tailpipe. However there is no coolant in the oil.-- which is a tipical sign of blown headgasket. Could it be just untorqued Headstud?

Any ideas pls. Thanks

 

Yep. Your headgasket is blown.

Don't even bother re-torquing them.
Just pull the head and have a machine shop inspect it.

Pull your plugs out . Tell us how they look like.

Yes your head gasket is blown. I just lifted the head on mine last week. Didn't burn any coolant but I still went ahead and replaced the headgasket to be safe even tho it looked fine.

 

Thanks guys that what I thoght too. What is the tipcal time to replace it that shops charge 3-4hrs?

 

It will be a good bit more than 3-4 hours I imagine. My best time for a HG swap is nearly 2 hours IIRC, and that was on my 2g which was built to practically fall apart as soon as I even showed it a wrench The first time on the EVO, with all the useless brackets and other BS in place, took closer to 4 hours, including the ARP stud install (takes at least 30 minutes to do it right). Shops usually over bill by a couple hours. The dealer would probably charge out something like 8-10 hours.

Is there any oil in the coolant? This, in my experience with the EVO and DSMs, is much more common than coolant in the oil. Oil pressure is higher than coolant pressure, so that's what determines the direction that it moves. I had completely filled my recovery tank with oil in the EVO over the winter when the HG went. Since oil floats on coolant/water, it ends up being pushed into the overflow when the motor warms up, then when it cools coolant is pulled in from the bottom of the overflow replacing it continually, until the overflow is all oil anyway Check it out, it's pretty obvious when you see it.

It could just be stretched/loose head bolts, which was what started the process on my car, but like others have said it's best to take it apart and fix it right.

 

Is your overflow bottle full? Check each plug one by one, shine a light down at the piston in each cylinder?

If you need someone to fix it, give Lucas a call. If you need his number let me know.
