I have a 96-24 valve motor, it has 300,00 miles on it and still runs great....but yesterday she started throwing oil out and over EVERYTHING....The timing cover is "cracked" they say the motor needs to come out to repair it???? $2700.00......don't sound right to me.Have any of you changed or repaired the timing cover on this motor?What could cause this condition?How bad of a job is it to change / repair?Where could I get a replacement cover?Is the timing cover on this motor steel or plasticMany thanks as always for your help. Randy

i have read some saying that the 01 and newer doesn't have to worry about it. i read where a few people with early 99s and 00s had the new case with the step, but most 24v seem to need the fix(as well as ALL 12v).

I submitted the repair procedure in the the Downloads section under "other documents" but you will have to wait until Michael looks at it before it is visible. It is for a 12V but should apply to early 24V if that is what you have. Has a great description and very good pictures of pulling the camshaft. There is a heat method of pulling the cam gear off the cam instead of removing the whole cam but that is usually reserved for experienced Cummins mechanics. The gear is heat treated for hardness so one has to be careful with a torch.

Heat it to about 250.

In our shop we always used the smoke test.Heat until the oil smokes on the part, don't go any hotter.Unless you want metal that you pull the temper out of it

If using Elshadow's idea there then a propane torch in most cases is fine because it can get much hotter than "Oil Smoke" for large parts. But small thing like bolt it can get them ret hot...

So I guess I should tear off the cover ect and perform the tab fix anyway, as there is no clear answer to the question as to if the 200 needs it eh??My case is not broken as yet, so I do not need to worry about heating the camshaft ect as I will not be needing to remove the case. Thx

I *think* there have been sparse reports of even the later year 24v's having issues, very rare though. That is why nobody is giving you a clear answer, they might not need it but then the next day it will break and you will be another rare victim and you will be hunting us all down for telling you not to do it

I recently replaced my vp44, removed the timing cover when I did it I inspected the dowel in question on my 2002 model I even used a center punch to check for any problems and found none on mine so I left it alone.

Thx to all, you know what really SUCKS about this whole timing case issue it--and I shouldn't admit this here but oh well--I replaced my VP44 1 month ago, and knew about the KDP prior, I must have had a brain fart and not remembered it at the time, I was almost there. Had the rad out and everything, would have been easier to do it then eh???
