Hello everyone...:)

I recently had some issues with my 01 750iL...:-(

Car started smoking(bluish smoke) and developed a rough idle plus tons of ECU codes...:-(..Engine cylinder misfire etc..

I did some research and found that the OSV valve might be the issue..

So I took the intake manifold off and discovered oil in the intake was pouring out.... I also removed all the cooling components (radiator, waterpump etc...)

Question...I am thinking of changing the head gasket while I have everything apart..Is this a big job(special tools etc) ..
I am on the fence over this since the somke was probably related to the oil in the intake..?

Any one do a headgasket on a V12?
