I was told today that the so-called "timing" cover on my 2000 Dodge is the source of my oil leak.

Not having been inside one of these engines before I hear from web sources that there is a big difference between the 12 valve and 24 valve in this area? From what I see on Ebay it appears that the 24 valve cam gear IS removable and that the cam itself does NOT have to be removed in order to do this job - is that correct?

So, in order to re-seal the cover/s on the front of the engine what is entailed, time-wise?

Again, this is a 2000 24 valve - NOT a 12 valve.

Thanks to anyone who has done this job.
