i took my tappet cover off the other day to paint it and for some reason all under the cover and around the rockers a bit was all white goey oil ....as if water was getting in my engine .....but its using no water and the sump oil is fine.....so anyways i cleaned it up and put it bac on and gave it a good drive and after being stopped for a while i looked under the filler cap and there was water condensation?????
\anyone got any ideas why this could be or is this a common prob for "A" engines.....it just seems to be on the top of the tappet cover and cap and nowhere else

thanx for all your help
