Kevin,
30 years ago I was working in a service station and a customer came in with a new to him Lincoln with noisy lifters and oil sludge for lubrication. He had me change the oil and fill the engine with ATF. He did this once a week for three weeks before switching back to oil. It cleaned up the engine and cured the lifters. While I wouldn't recomend doing that with a Rover, I would try running the lightest weight oil recomended and changing it a couple of times. Something along the lines of a 10w/30 weight. I'd then switch to the oil I intend to stay with.
Good Luck

There was a post before related to this issue. It seems like a common problem to 96+ Disco and people seem to have good result after replacing 1 qt of Rislone with regular engine oil when you change your engine oil.
You'd better try that before expensive valve job.

I would try a few additives and see what happens. I just had the very expensive valve job done but tried a few additives, including BG44K, before I had to get it done. I had two problem valves, which after looking at them, we not going to be affected by anything you'd put in the tank or the engine. Just way too much buildup on them.
Now what I was told and this is how I understand it is that sometime in 1997 new designed exhaust valves came out with a carbon cutting edge, which should have eliminated carbon buildup causing the valve problem. They are different, I felt the ones that came out of my 97 and some from an earlier 4.0 motor. But..... it apprears that the new design still has problems and LR blames poor US gas for the continuing problem saying they aren't apparent in the UK. How true that is I don't know. So the fix is to remove and clean the valves and grind around the edge of the valve seat and this should be a guaranteed fix? |

If you really want to remove all the varnishes, metallic particles, swarf, sludge, crud clean the upper end restore the performance to your engine.
If dammage has occured no ammount of cleaning will fix it.. Call around find a service facility that has the Blistine engine flush system. It is not a gimmick GM uses it Mercedes Benz uses it and I believe some LR dealers use it.
