Yes!....If you have been doing short trips the engine may not have got hot enough to boil off the contaminates, this could be responsible for the yuck under your cap

Cheers Rob,

I hope so!!! - Only drama is that I hooked my finger under the rocker cover and there is a fairly well established slime as far as the finger can reach!! I suspected I had bad fuel a couple of weeks ago, but it didn't run THAT badly! - other theory (half baked) that i had was water ingress through the the air cleaner breather to rocker cover small hose??, I did recently 'park' it in 3-1/2 foot of water??? ?? it's quite odd and I am still hoping that you may be correct but there is an awful lot of gunk up there. Last time I did a head gasket I had sludge in the sump too though and a substantial water loss?? - how much slime do you think could accumulate from contaminants???


Cheers mate,
Kris

Well that could do it. Do you have any oil leaks which could let water in?

Parking it in that amount of water is likely to let water in the front seal - it is designed mainly to keep oil in not water out.

I would also ensure that you have either the pre - antipollution engine ventilation or the full positive carankcase system - if you have the antipollution setup (which is what you should have in a S3) but with the PCV valve blocked off (or not working) the symptoms you have got is exactly what to expect, especially if you live in a humid climate.

I contemplated the front main seal, but.....there is no contamination in the sump whatsoever, Please excuse my ignorance, but wouldn't water ingress via the front seal create sump contam. also? or could it have 'vapourised' and just left the gunk up top??

Cheers

Hi Kris
The sudden cooling of the engine block would cause suction,so its possible the water was sucked in thru that front seal.
I wonder if all the water has been evaporated off and the sludge at the top of the engine is all thats left.
