5.9l, 24 valve, H.O. diesel. I think the timing cover is leaking. Not really sure where its coming from. Leaking quite a bit of oil, about 1 gallon in about 1500miles. Its such a mess that I can't tell. Is there a common place for oil to leak on these engines? I was told that in order to remove the timing cover, I would have to tear apart the valve train and remove the camshaft, is this true?
Before replacing the timing cover gasket, crawl underneath the truck and spray everything with brake parts cleaner, then wipe with rags until dry & clean. Start the truck, then crawl under the front of the truck, using a flashlight to spot leaks. Chances are the leak is the seal between the vacuum pump and power steering pump. If this is the case, contact Pete Gould at fixinrams.com. He can sell you an uprated seal kit, or provide you with a totally remanned vacuum pump reasonably. The vacuum pump runs about $375, replacing front cover gasket is about $1100. Hope this helps

I would say to you, first get some engine cleaner spray on that area of the engine and hose off. This will give you a much better idea of where oil is coming from. I think you may have a very bad valve cover gasket. When you drive the car the oil leakage will be more visible. GOOD LUCK FRIEND.
What makes you think the valve cover was leaking,was oil coming from there.Exactly where is it leaking from.If the oil filter is tighten too tight,then it will leak,also by the oil filter is the oil pressure switch,it's screwed into block,it can leak.The rear oil seal can leak,where engine and transmission meet.If valve cover is not installed correctly,it will leak and loose compression.
Dear Sir, Here is the oil leaking Problem Identifying Technique
Engine oil leaks from the valve cover gasket are common.
The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.
External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.
If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.
Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.
oil leaks can come from many things.like front timing cover crankshaft seal, rear main oil seal,with engine running look under car around oil pan area check see if you see heavy oil leak which will come from loose or damage oil filter and seal or check oil pressure sending unit at bottom right rear engine block or right rear corner of the oil pump.if oil leak small leak the front crankshaft seal and rear main seal leaking .
The Chrysler minivan products all had leaking problems. I have had 5 or 6 different Dodge or Plymouth minivans from 88 to 99. How bad is it. The most common thing is Valve cover leaks. Front and rear seals in the engine leak as well as the oil pan gasket. If its leaking a little bit at a time open the hood and look at the front and rear of the engine. Do you see grease and oil that has gone down the sides of the engine? Do you see a lot of grease on the engine with some clean streaks going through it. You may be able to see where its leaking from. If you know someone that knows what their doing have them change the leaky gasket/s. If not you can probably have it repaired for less than buying another van unless other things are seriously wrong with the van.
Hope this helps... Dale
NO, the EGR valve routes exhaust gases to the intake manifold, so there no way it could ever leak oil. you will need to clean the engine real good, I would use "brake cleaner" and then run it and find out were the leak is starting from.
