I discovered mayo around the oil filler cap yesterday after it had all that head work last month on my car as the car came up with the oil light a few times... there is an oil leak too. The water is also low.

I need advice...

Im no expert but I thought mayo was always bad? After reading a bit, it seems like its either not much to worry about, or very bad.

Mayo = oil + water

Couple of causes, the one to worry about least is condensation created in the engine, usually caused by a poor fitting seal, allowing damp air to get in.

The worst case scenario is a leaking cylinder head gasket. Depending on where it has gone will determine whether or not water is getting into the crankcase. It can be leaking into the cylinder head chamber, so you wouldnt necessarily get an oil and water mix on the dipstick - it all depends on whether it has just started to go.

Quickest way to find out if it is your cylinder head gasket is to get a compression test done.

Thats a bit of relief... but if the oil is leaking, which it is Ill have to definitely id that leak...

p.s. its always good to act dumb in these situations.... that way if they bs you you can wait till the end to point it out when theyve dug themselves into a hole

Well it seems the oil filter had a bad leak and the mayo was from short journeys. So it just needed a new filter.

I also got the bottom ball joints replaced and a newer drop link than the one I had.

Now the car runs sweet as a nut

Hes been spreading it on his chips too

The filter leaked and it was raining during the short trips which made the mayo ?

No idea, but it there was a leak from the filter (when the pressure in the engine got high) I can only assume that water *could* seap in as it has been sitting on my mams lawn from July to pretty much now without being driven. So who knows but there was no water loss and the oil was clear when it was coming out, so that means that there has to have been a bit of water in the engine, from what ever it was.

Great

Could have been condensation water + oil if it has been sitting so long with rain, sun rain etc.
