Timing chain wore through upper oil pan!
I just put a newer 2.4 diesel in my Land Rover after the old one started making noise and was beginning to get VERY hard to start especially in the cold. I decided to pull the old one apart and see if I could find what was wrong. I don’t have the head off yet and I expect to find a bad head gasket as this engine got pretty hot a few years ago, but I did see that the timing chain was loose enough to wear a hole through the bottom of the upper oil pan! The chain was replaced about 30k ago so I wasn’t expecting this. Could the chain tensioner have gone bad?
I didn’t realize how bad this was running until I heard the new one. Even with the noise and the hard starting, it still had almost as much power as this newer one does! How often do you guys change these chains? The new engine has 67k on it now and I’m assuming it’s never been changed. Thanks for any input. Jim Last edited by MercedesRover; 11-24-2004 at 04:58 PM.

It does sound like you had a bad tensioner. A MB chain should last the life of the engine, or at least 200k miles. The chain rubbing on the upper pan sounds loose to me.

The chain should last a long time, at the very least 150k, I think some have gone 300k plus on well maintained engines. Sounds like the tensioner probably went bad for that to be happening. If you don't want that old engine I'd be willing to take it off your hands.

I'm going to keep the head and some of the smaller stuff but if you want the bottom end, it's together and going to the dump. It's in CT. Come and get it!
Let me know jim pbs@mohawk.net
