I have a 2000 disco and i was wondering what the hell is that ticking sound? Is it bad? I heard that it is the values or something. Please tell me what this is?

our 2001 D2 had a bad rocker arm at 500 miles. The rocker amrs are alluminum with metal inserts and one of the metal inserts came loose. Dealer said there was a "bulliten" out for a bad batch of rocker arms. They replaced 15 of the 16 arms under warranty. Only one was bad but the others were part of the suspect batch. So far so good, no more ticking (2500mi).

sometimes a ticking sound is confused for a gasket leak as well. collector gasket and manifold are two that do go bad or where the bolts come loose and cause the leaking that way. then the ticking noise sets in. little early to be doing that on a 2000, but it can happen.

Supporting Garrett's mail here.. I had a particular "mechanical" tick on my '94 V8 - dissappeared completely when I had the exhaust manifold skimmed and resealed.

Start the engin and (while cold) try to detect escaping exhaust gas around the manifold gasket.

had my d2 in the shop for the same thing. annoying as hell. they told me it's a compressor designed for california emmissions that helps the truck burn cleaner to meet there specs. they originaly thought it was the rocker arms as well ,but it was this.
