Title: Mates valver oil query....
Post by: dan7 on 11 April 2007, 17:22

1990 spec 1.8 16v. 120k. Very small amount of mayo on inside of oil filler cap. Some mayo on dipstick, but after wiping and redipping a few times, it dissappears and clean oil is present. oil buzzer and warning light comes on now and again, especially when going uphill. NO loss in power, no oil in coolant. Any ideas guys?

Run the engine up to temperature and re-dip the oil and check for water. Remember that oil floats on water, so any water will be on the bottom of the sump when the engine is cold. If the oil level seems to be a little high then suspect water in the oil due to head gasket failure.
The oil light will come on if oil pressure is low, so if the pump is trying to suck water, the viscocity will not be sufficient to generate pressure.

would it not be a good idea to un-do the sump plug at bottom and check i any water is apparant in a small sample of oil drained?

some small ammount of mayo is to be expected, just condensation buildup.  If you get a LOT especially on the dipstick then start worrying!
