M30 head gasket
Discussion
Chaps,
I seem to have identified the coolant leak on my E32 as there is some emulsification on the oil filler cap.
How much am I looking at to get the head gasket changed?
I'd normally take it to CPC to get it done but as it would involve me driving it 400 miles I'd rather not.
Is it easy to do or is it a world of pain?
TIA

What are the chances it's cracked the head too?
It's running fine, it's just got the tell-tale mayo under the oil filler cap.
I hate cars right now.
It could just be condensation this weather...It's running fine, it's just got the tell-tale mayo under the oil filler cap.

Are there any green coolant stains?
The coolant loss is about 3/4 of an inch in the expansion bottle every 4-5 days.
There are no stains on the inlet side and i can't see on the exhaust manifold side.
Oil is clean at the dipstick, just under the cap has the emulsification.
If you have a coolant pressure tester, get the car hot and remove the rocker cover then pressurize the system and check the head around cyls 4-6 under the camshafts for beading of water if they go porous that tends to be where they go.
Alternatively get the head to an engine builders and get it crack tested.

It's been suggested that due to the cold weather and short trips could have contributed to the mayo under the filler cap.
Temp stays solidly at the midway point and there is heat from the vents.
If you do short journeys and there is only a little bit under the cap it's probably normal condensation.
Try and get a pressure tester and leave it over night, check the water pump, heater valve by the bulkhead and heater matrix behind the dash for leaks. They are the usual suspects for slow leaks.
