oil leak after cold weather start, then stop

1995 7.3 powerstroke, 100,000 miles (have changed injectors, glow plugs). In cold weather (32 degrees) engine hard to start; then very rough, noisy idle; then when immediately shut off (without driving), considerable oil found on ground. Otherwise runs great. Oil seems to be an overflow or something. Does not happen when engine is warm or weather is warm. Any ideas?

Check the external oil cooler. Mine does the same leaking from there but only when quite cold. Dealer says it has a tiny crack in it & that it isn't unusual! Also check your glow plugs could cause rough idle when cold.

OR, check your EBPV housing. Oil LOVES to come out of the actuator barrel. I had that problem and solved it by cutting the barrel off and welding the oil holes shut...

Re: oil leak after cold weather start, then stop

Ysiad Man I wish I had a 95 with just 100k.
I've seemed to have experienced the same leak a couple times over the years. It was disturbing seeing the puddle of oil. looked like mine oil came from drivers valve cover. Started plugging the truck in and Eliminated hard starts no more oil leak. Find my hard start was a glow plug relay. Another time it was the glow plug wiring harnesses and valve cover plugs. I wonder if the cause of our leaks could be when the valve cover plugs get hot and swell the valve cover gasket leaks until it cools. Seemed to only leak during cold hard starts. Fix the hard start problem.

Re: oil leak after cold weather start, then stop

Probably from the external oil cooler. I had the o-rings replaced, there are o-rings that seal the oil from the outside and also seal from the coolant. Mine were brittle and cracked, leaked to the outside. The inside were also hard and brittle, no leak. Hate to think of coolant in the oil or oil in the coolant. Peace of mind is worth a little $$$.

I was only wrong once, that was when I thought I was wrong, but wasn't.
