How much leakage on a Deuce

[bigmike]

In the words of my good friend who worked on deuces for 25 yrs "best way to kill a deuce is by NOT running it. Run her for a while and watch the leaks stop". His advice has worked good for me. Run her hard for a while and then see what remains leaking.

Kind of OT but a guy in the Army once told me " If a Blackhawk isn't leaking Hyd oil don't get in it, It's out".

There appears to be a slight leak on the passengers side near the center of the engine block from behind the exhaust manifold.

There also appears to be a very small leak on the drivers side under the filters mounted in the middle of the engine.

All 7 of mine leak. The leaks on the passenger side of the block seem to be coming from the intake manifold where it bolts to the block. I think this if from the turbo. I think it leaks a small amount when the truck is shut down. Then when the truck is started up the turbo pressure causes it to come out past the manifold gaskets. The more I drive it the less it seems to leak. The oil filter leak will probably stop the next time you change the oil. Just make sure new gaskets are used.

My Duece + 5 ton dont leak but I made them that way . Keep a cheak on all your fluids and replace seals,boots,gaskets etc. as you go.

I noticed some oil drops while my truck idled during a 900 mile recovery from Warner Robbins. 12,000 miles on an '87. Cleaned the engine and found slight seep at the front of the forward head within 100 miles. Kept an eye on it for another 500 miles and find the front edge of the block is damp, but no dripping. While the leakage isn't reflected by lower oil level, I do wonder if the gasket is being eroded or weakened and will fail catastrophically.

Lost a little oil from the bell housing too, so assume the rear main seal is flaky. I figure on watching it and procrastinating on replacement until it becomes severe.

I hope I'm on the right track.
