I've noticed some creamy goodness in the oil filler cap of late which signals either HG or cooler.

I've been reliably informed that the MV6 engines had steel HG and are unlikely to fail and on finding the mayo first thing to check/replace is the oil cooler.

I see that it is situated inbetween the 'V' and is quite small in size, has anyone upgraded to a Mocal oil cooler kit for instance?  Is it possible to do?

I've had a quick look for a guide and found nothing.

An intersting conclusion.....wrong but, interesting none the less.

Care to clear up where i've gone wrong then?  :-?

Mayo in the filler neck & cap is normal on the V6`s. Usually due to short journeys, engine not reaching max optimum running temp causing condensation in filler neck resulting in said "mayo"

Simples...oil pressure is huge with engine running so if the oil cooler fails you get loads of oil in the water.

The water pressure will remain moderate after engine turn off so you may get a small amount of water in the oil.

The issue is the filer neck, its long and gets cooled, it also does not get oil spashed round it washing it down from the cam rotation.

As a result the water in the crank case (present in the blowby gases etc) condenses in the filler and causes a mayo.....this is worse with certain oils (like shitty castrol) and short runs.

Ooooooooooh my bad!

Sorry chaps for the confusion!

A very thorough explanation tho, thank you
