water in oil

[coops71]

I took the oil filler off my recently rebuilt 3.9(new cam/heads fiddled) and noticed white oil film. Block has been left alone. I had the heads refaced, cleaned block face completely and noted that the cylinders had no sign of steam cleaning from a bad liner. ARP head studs etc, torqued down right etc. Anyway there seems to be a slight leak of coolant into the oil. As mentionned I noticed this from the oil filler cap having a white haze on it and a bit of steam coming out of filler while running. Car runs excellent. Really can't see a lot of coolant gone missing. Drained running in oil(for cam) and noted it was normal. Coolant is clear. Thinking it might be timing cover gasket? Chucked in some Chemiweld out of desperation. have noticed lack of milkyness since. Any other ideas to the reason for this issue?

This may not help, but I had similar in my RRC. Was not using any coolant, no other signs of water in oil or oil in water, no other leaks, engine running fine apart from a white film around filler cap. The only thing I could come up with was there was some sort of condensation occurring around the cap. May also have been related to being run on lpg not sure.

That gives me a reassuring feeling. Im running lpg for much of the time. Found condensation in the breather running into the air cleaner too.

Very common if you do lots of short trips, don't get up to full operating temp and engine oil doesn't get hot enough to 'boil' off any water condensation.

Old engineering adage says - for every litre of fuel you burn you'll make a litre of water!

I've seen rocker covers full of white emulsion/sludge on vehicles that might be used 5 times daily....but only on short trips.

One of the reasons taxi engines last for a million K's - they rarely get cold!

Get into the habit of taking your vehicle for a long drive over the weekend - your oil will thankyou;)....or replace your oil and filter on a more regular basis.

I'd refrain from throwing products like Chemiweld into a functional engine

I've run mine almost 99% on LPG , and never ever had any milkiness on the cap, The oil is also a lot cleaner when it's changed. If you say you tried Chemiweld and it's decreased then it must be a small amount of coolant getting inthere, a teaspoon here and there over time is hardly noticable in the coolant tank.

It had been idling etc while I was tuning and playing around. Bonnet up and the temperature over here is in single figures often when Ive been messing with it. Rocker covers would have been getting cool, especially due to the fact that Ive been belting around the place with the bonnet half latched due to killing the bonnet cable. The engine has not run for more than ten minutes at a time. Took it out and thrashed the life out of it for 30 mins yesterday. May have been the chemiweld. May have been that I got the oil hot and boiled the mayonnaise off. Its gone anyway. Im hoping its not the chemiweld.
