Have found a small amount of mayo inside the coolant cap

And the engine oil level is slightly low

Will check compressions ASAP

Have a nasty feeling that the well known top of cylinder problems are starting

10-40 or 50W is more suitable.

Using light oils to reduce rolling resistance to the min Lauren

I have Mobil1(0w30) in it at the mo.

Perhaps that is escaping round the piston rings more

oil getting past the rings result in mayo in the cap?
Any excess oil bypassing the rings would simply be burnt off and you would have blue smoke from the exhaust.Mayo in the cap is the result of condensation due to short journeys, frequent short starts and lack of getting up to temp etc.
If your oil is normal colour in the sump then the Mayo is just condensation, although i have to say running the incorrect oil and also automatic transmission fluid in your gearbox is madness, you're just asking for trouble.
But hey, we've been here before and not a single word i or anyone says will change your mind.

Mayo is a mixture of oil and coolant![]()

Probably the result of the well known top of cylinder damage to which the 4AGE is prone
10 mile test run today at town speeds:
About a pint of coolant disappeared
Fully heated engine failed to remain running each time foot removed from throttle
Any ideas?

Peter I hate to say this but this eventually happened to my race engine..
.
It blew up spectacularly as I had cylinder no 4 pitting.
I only found out i had Mayo after it blew up on a very brisk drive.
It kept cutting out up to temp etc
