Relating back to my previous post
http://www.peachparts.com/shopforum/diesel-discussion/309700-1979-240d.html I have gotten more information from the previous owner. He gave me a quote from the shop that did the repair. I hope it can clarify something. So the first step would be to check the chain, gears and tensioner. |

I have an engine from a forum member that rebuilt it very nicely, top of the line stuff all the way through. But did not do the vacuum pump. About 8000 miles later the pump broke.
Here is the list of broken parts as a result, timing chain cam shaft drive shaft for ip oil pan the aluminum one cam towers Hope yours is not this bad, just taking off the valve cover will show a lot. Follow the rest of the advice from others if the chain does not look right.

If the vac pump fails the parts fall down and jam the cam chain, which breaks it and then the piston hits a valve and breaks the cam.
Don't ask how I know all this.

You do have to remove the valve cover and inspect the chain and other things like the cam for breakage etc. There is no way out of this.

The valve cover has been removed. The chain looks okay and there is no damage to it. Is there any way to see the bottom of the chain? I suspect that a piece of metal has jammed between the chain and some teeth. If the chain didn't break would there be damage to the cylinder? Also, the previous owner told me that when he took it to the mechanic they said that the timing was 14 degrees off.

That pdf you posted indicates the problem is more than just a stuck chain. it suggests one of the gears has spun on its shaft and the timing being off is the reason for this. You're going to have to get a close look at all the gears--cam, timing device, crank.

If a piece of metal was stuck in between the chain and a gear would that throw the timing off?

I don't think so. The chain has jumped a tooth or a gear has turned I think.

Can a mod put all these threads together into one so the advice is clear and the diagnostics and solution can be seen in one place?

I understand how people feel when something terrible like this happens but it is really irritating to have to try and help with the same problem across several threads. Can we merge into one please?

Safest bet now if you have little experience at repairing and rebuilding things would be a good used engine perhaps. You may need help evaluating a used engine as well. Before purchasing it. You and a friend with some experience install the replacement.
Paid for service is not a practical alternative for a situation like this. Too much money gets involved. You even want a good used engine pretty reasonable in price to go at this.. What is currently wrong may even be a manageble repair but without experience perhaps beyond your ability.We learn mechanical things by stages over time. Your current problems are not a particularily good enterance or starting point. If you have a friend with more experience than yourself that is willing to help might change things. What I read into the paid for report was that this car was little cared for. The mechanic seemed to know his way around to some extent. He was still not certain he could deliver a good repair at a price the customer could live with. Or wanted to really get into it even. We all have some lmitations and in my case if an automatic transmission fails. Other than checking pretty simple things I would get a good used replacement before attempting to totally rebuild it myself. . This approach is both quicker and cheaper overall plus the downtime of the car is far less. The problem is to find a good used transmission both cheap and available. That sometimes takes a little effort. Last edited by barry123400; 12-13-2011 at 10:58 AM. |

To check if the shavings are magnetic, take a magnet, touch it to the shavings. If the shavings stick to the magnet, they are magnetic.
