I'm hoping you can help. What could be the reasons other than a head gasket issue that my oil in my jag when I check it looks the color of cappucino? I it also smelled to me like gasoline..you help is appreciated,...thanks, Lisa

Lisa, I know the problem....its a Jaguar

No really, what is the problem exactly? Is it leaking? Is your engine ticking? Do you have loss of power?
You need to elaborate on the problem

I know I know all about jags..this is my 3rd one you think I would have learned from previous issues but I kept thinking maybe this year (1996) would be better than the previous jags..The car runs beautifully no ticking no leaks. I just had a re-built transmission about 2 months ago and the funny thing is when the trans went there were no signs of it going prior to that happening...Lisa

The color of the oil sound like moisture, either from a coolant leak into the crankcase or from not being driven enough to get the oil hot and the water boiled off. The gas smell could be from running too rich.

I'd change the oil and then see if the symptoms return.

Thanks..I use the car every day so it's not from not being driven enough..I am in that forum now..thanks for the tips, Lisa

Sounds like excess fuel + coolant leaking into the oil.


Have a great day.

And what does that mean? and if so how is that happening? Thanks, Lisa

Head gasket or a cracked head will cause this.

I know but my original post asked for other reasons than head gasket issues that would cause this..Lisa

If the oil smells like gasoline & you have a fuelpressure regulator with a vacuum line going into the intake manifold, I would check it for a leaky diaphragm.

Hi..
I've searched for this and I ended up on this thread..
same problem,the oil appearing to be like a cappuccino..
which really smells like a gasoline..
I don't know which part to look at..
where to begin looking..

You have a coolant leak.
Have the cooling system pressure tested.
