Default Sell 335 or replace seeping head gasket? - 10-29-2015, 09:10 PM

My car is a 2008 n54 335 and I have a seeping head gasket. The car has 133k on it. Would you sell the car or replace the head gasket? Everything else on the car is well maintained. Is it possible to replace the head gasket without removing the engine? Dealer wants 6k to replace head gasket. Any advice is greatly appreciated!

Ummmmm 6k to replace the head gasket?? LMAO Find a guy or a DIY. I don't remember what the head gasket costs but it would maybe be $100 more than that to have it done. First rule of BMW club is DON'T USE THE STEALERSHIP!!! Really though, it depends, do you want the car? If so just replace the gasket and call it a day. If not, perfect excuse to get rid of it!

How are you able to tell that you have a seeping head gasket? Do you have oil in your coolant or coolant in your oil? I have an oil leak on the exhaust side of the engine that I cannnot tell where it is from.

Thanks

I have a small amount of oil bubbling out of the head when the engine is at operating temperature. I know its not the valve cover or OFHG because it is right where the head meets up. And I can physically see the head bubbling oil when the car is running. I do not have coolant in my oil or oil in my coolant. Internally everything seems fine. It's just the head is seeping oil externally. Sounds to me like you have a Valve cover gasket leak. Oil runs down the block on that side and lands on the exhaust. There is DIY's all over the forums. My leak is on the intake side.

While I agree that $6k is excessive (it's supposed to be) replacing the head gasket can be a pretty big deal since the turbos have to come off and you have to re-time the engine which requires renting the special tools as well as knowing how to use them and the knacks associated with it. For these types of jobs, you're better off using the Bentley Manual to wipe your @ss with. And yes, the head gasket is about $100 but you'll also need new head bolts and vanos bolts and they all require torque and angle.

I don't think it is my VC gasket. I see oil where the head meets the short block and not above it. I am hoping it is my OFGH where I had a leak and the oil may have went down and around the side of the engine. I have no way knowing since the turbos are in the way during inspection (my ** install).

How are you able to see where the head meets the short block on the intake side? You had your intake manifold off?

I could see it in between the intake manifold. So I then decided to walnut blast the car and while taking the intake off I could see where the oil was leaking at the seam.

Dont drive it. Find an indy. 6k is twice as expensive as it should be.

It's not easy but it's not 6k difficult either. 20 hours at 100 an hour is 2k labor . Head gasket should take about half that time. Now once it's apart and they start checking you may end up finding out the reason your leaking : Warped head, block damage, or 'hopefully' compromised hG

Did you overheat it?
Are you over boosting ?

If the car is at stock boost levels and hasn't been overheated, aside from a defective part from the factory, that's an unusual failure at your mileage.
.

:: Edit :: Just saw your signature line. You probably overboosted and compromised the HG or warped the head. Speed is just a question of $$ you gonna pay one day one way or another.
