Neither am I, but apparently the sleeves slip once it warms up to normal operarting temps. Maybe it takes one overheat to break them loose, I don't know.
I thought mine had a slipped sleeve, given it's loud rpm matching tapping after warm up. But, all bearings were worn out, the block deck showed no clean line between the sleeve and block. They were still blended from the original milling after sleeve install. The head gaskets had no impressions on the bottom either.
Regardless, my Dad and I pinned all 8!
The engine was already out, making it very simple.
I glued the bolts in with loc-tite, and safety wired each bolt to the block.
They will never slip now.

 

 

How do you find someone to work on it and what is the cost?

This happened after I put big tires on the car. So I don't know why it would be overheating enough tick just because of bigger tires.

 

There are so many things that can tick in these engines, it's not nesacerily a slipped sleeve.
Sorry, I don't know who in your area can work on it.

And, bigger tires are heavier. They make the engine work harder. They can cause engine and transmission temperatures to rise.

 

As above increasing the load leads to weak parts of the system failing sooner... But it's a Rover and could have more than one unrelated problem at the same time.

Now, since this is the internet and everyone likes to be argumentative, you're liable to say "Hey, he pinned those liners with the motor *out* of his Disco 2."

...and you'd be correct on that point, but missing the fact that you can drain the oil and drop the oil pan to achieve the same end result from below... with the motor still in your Disco 2.

You can also pull off the heads and achieve the same end results from above... with the motor still in your Disco 2.

Note that the job doesn't take much time. Note that the parts costs are trivial.

Also, you can "pin" all of your cylinder sleeves by replacing your cheap rubber head gaskets with real all-metal Cometic head gaskets to achieve the same result: https://landroverforums.com/forum/di...19/#post386380

Head gasket jobs are easily done with your motor still in your Disco 2.

 

The tick is highly overrated.

if you've lost a cylinder, find coolant in your oil, steam cleaned effect etc then you might have liner movement.

however, if you havent cleaned the internals of shellac that builds up then that tick can be anything.

 

Add to that cam bearings seem to be coming into play more frequently as they are found walking out of the journals
