FYI - I have have the same tick that only happens when warm and goes away above 1,500 RPM. I took off the inspection plate on the bell housing and you can't see anyting. You can only see the torque converter and the very edge of the flex plate. Looks like the only surefire diagnosis is to take off the oil pan.

i picked up one of those at habor freight a couple of weeks ago, it works pretty good i had a 20% off coupon which makes it work that much better. by the way anyone who going to harbor freight, the run ads in all the bigger magizine that have 20% off coupons in them, 4wheel, C&D, JP maginzines all have them.

Okay, nice write up to one of many reasons for this noise issue.... Like many issues with mechanical- electrical devices, the more parts, the more potential sources. With LR's that seems to be even more true.... Before I go furthr, I am an owner of two disco II's, an ASE master tech and have a busy shop where we work on a fair amount of LR's...
This noise issue (ticking) is very common and equally, the causes and remedies varied.. Good to check suspect areas in order of ease but don't discount previous advise on cam wear, really poor maintenance, the dreaded 03 AND some 04 motors that were known disasters (TSB printed March 03!) there have been rocker arm and shaft problems, lifter issues and wrist pins to name a few. The whole cylinder sleeve rant (in my opinion from experience) is so rare it hardly deserves the attention it gets. Further, I've found really worn litters in motors that sounded tight while finding nothing of consequence in rattle boxes.. One suggestion though, oil gauge install that's really easy... I use Autometer electronic sending unit w/ gauge with a VDO POD on the left of cluster. Put them in lots of Rovers. You can tap into the timing cover ports plugged on the flow side of the pump circuit without losing the stock sender for dash ught, run the wire in a section of vac line for protection and just wire the remaining circuits like any gauge. It's very cheap insurance as you can read pressure issues well in advance of an engine about to grenade.
This noise issue on these motors is so prevalent on the net, IATN, other services because it's so elusive and so many possibilities exist. It's not an ABS/ traction control type issue where you can almost order parts before proceeding due to the common failure issue. I'm not bashing the posted fix, it's great, just hope everyone doesn't show up at the trans shop on Monday morning with a flex plate, six pack of beer and a check book....
