Head gasket?

[anonymous-user]

Just had a head gasket repaired on a 330ci. Done about 200 miles since it was repaired and I now have "custard" under the filler cap and the oil is now getting right to the top of the engine when it never used to. I also topped the oil up before the 200 miles and the level is now down at the minimum mark. However, it has not used any coolant, there is no white smoke and there does not appear to be any contamination of the coolant (no residue under the coolant filler cap)

I appreciate these things are not easy to diagnose over the internet, but anyone got any ideas why there would be such drastic changes since having a head gasket repaired?

Any advice much appreciated.

get the car up to temperature without the coolant cap on. top the coolant up to the top and watch for bubbles coming up. there shouldn't be any. if there are, its usually a sign of exhaust gas getting into the coolant via a blown head gasket or cracked head / block.

how many miles has it done and why was the head gasket replaced?

Will give that a go. It's done 96000 and the gasket was done as the head was pourous at the front and coolant was leaking out.

Hmmmm ok !

I'd suggest you do nothing and return it to whoever did the work, and explain things still don't seem to be correct.

Having just looked at your profile to see where you are, do you have a reme unit around ?

If so, I'd have a chat with them.

My 530i gets custard under the filler cap every winter and has done for the last 5 years. It's condensation formed on the short journeys I do. Goes away after a long blast.

Strangely it seems to have rectified itself now - I will just monitor the coolant and oil levels and see how it goes. The custard has all but gone.

Might give it a flush and oil change if the levels remain constant for a week or so.
