I got a hawkeye sti and think the head gasket gone. Oily gunk on rad cap

Going to get a sniff test done today but does any one know any body around north London, Hertfordshire, Essex area that are good and well priced to do it

Cheers

highly unusual IMO for the head gasket to fail and blow into an oilway, generally they blow from head into combustion chamber and you see water problems

possible its simply condensation which is common at this time of year in particular if the car is used for short trips

did you check the oil cap in the morning before driving?

If the cooling system is running normal temps and the fans are cutting in as normal, clean the 'mayo' out of the cap and run it for a week and check again.
Could be down to short journeys as mentioned above James.

Not common to see that on the rad cap or coolant cap though its a sealed system and does not create or receive condensation at all.

Check the overflow tank for level and also contamination (as in gunge/mayo) in the coolant.

But as you say you need to get a litmus test done on the coolant.

It does sound like head gasket, even completely std cars have that problem.

As Bob says you can't get condensation Mayo on a rad cap, that only happens on the oil filler cap. If oil is in the cooling system it can only come from HG failure or a problem in the oil filter modine causing fluids to mix. Unless someone accidentally topped up the cooling system with an oil.
