I'm at wit's end with an oil leak problem on my 1994 Coachmen Destiny. The coach has 70,000 miles. A couple of years ago, I took it to TransWest (Denver) to find and fix the problem. $3500.00 later, I continued to encounter a leak. I was told the leak existed because the injector pump shaft had worn and the pump needed to be replaced. The leak persisted and I was then told by TransWest that it was the oil pan gasket. $400.00 was spent replacing the gasket. I drove it home and the leak continued. I took it back to TransWest last week for one more final determination. This time, they are telling me it's the front timing gear housing gasket and the quote to replace it is $3400.00. I'm beyond upset at this point. I've put a lot into this beautiful old coach and I'd like to keep it. I just can't afford another speculative repair. Otherwise, the coach runs and operates beautifully. Suggestions anyone?

Has the leak lessened everytime?
I'd get a second opinion if possible just to see where you stand. And find out if you really had 3 leaks instead of 1.

The leak has not lessened since it was first noticed (Sept. 2010). Thanks very much. TransWest assured me the previous work was needed.

About 6 years ago, I had a leak that left oil trace on the front lower part of my timing cover and on the rear side of that cover in front of the injection pump along with spots on the ground.

You did not indicate what engine you have but mine is a C8.3L Cummins mechanical.

Cummins West took a look and estimated @ $2000 to replace the gasket and update the timing cover. They also indicated it was a common repair.

A fellow on another forum indicated he too had a history of that leak. He had a knowledgeable buddy to directed him to Permatex Form A Seal Leak Repair in a $6 spray can at Napa.

He cleaned the back of the timing gear cover and the edge where it meets the engine block with brake cleaner. Then he sprayed several coats of the Permatex. At that time his leak had stopped for more than two years.

I followed his procedures, but had to apply the Permatex on two occasions to stop the leak. Mine has been good for about 5 years and about 30,000 miles.

This is not an official fix. It is not supported by good mechanical procedures or knowledge. I just did it and it has worked so far with no related problems.

Perhaps, if you have the same engine, you have the same problem?

Stick an air hose in the oil fill tube and seal it and put about 2lbs pressure in you engine and see if you see the leak. That's how I find them. No guessing.

If it's a gasket sometimes you can clean it with alcohol (I use MEK) and get some permatex high temp red silicon and seal it.

After all of the money, you've expended to TransWest, and the problem still exsists, I think me and TransWest, would have a meeting of the minds, and if that didn't work, a meeting of the lawyers! After the first $3500, until it was fixed should have been on them! To my way of thinking, they owe you, big time.
