So there is a strong possibility i will need to replace the engine in my 02 disco. it has 91K miles on it and has a lower engine issue (rod knock). the truck was purchased "certified pre-owned" from the dealer and has always been maintained/serviced with dealer/specialists. the question is should i make a fuss with LR to try and get some kind of retribution. 91K seems too soon to replace the engine, especially the way i took care of it. i am frustrated but still love my truck (kicking myself in the *** for not getting that extended warranty to 100K). any insight dealing with LR on an issue such as this would be appreciated. i assume i will be on my own on this one but thought it might be worth the effort. worst they could say is no, right? thanks.

Rovers rarely ever have a lower end rod knock, how do you know yours does, and if it does, why not do a quick rebuild?

 

I would rule out rod knock, most likey bad cats, but to answer your question unless you bought the truck brand new and had every service ever done at the dealer they wont do a thing for you.
And a extended warrenty wouldnt do anything either because there is nothing wrong with the engine...it is still running.
By Federal Law there is a warenty on the emissions system of the truck for 150,000? miles, it will be in your owners manual.

 

i am not 100% certain that it is a rod knock. however, three mechanics have looked at it and all say rod knock. The third guy is currently taking a closer look. i briefly explained the problem in another post (title: rod knock???). the issue is a knocking sound coming from the engine when accelerating/decelerating. when idling, the knock will appear as the engine warms.

as for a rebuild, that is still an option. i am waiting to get a clear answer on the issue and what it will take to rebuild. however, i was told that a rebuild may be more costly/complicated than replacing the engine.

 

also, i dont think it is bad cats b/c the engine has not overheated.

 

The engine over heating has nothing to do with the cats, that would be the cylinder sleeves.
If the truck was ran for a long time with a rough run/mis fire then it will burn up the cats and when they go bad their guts fall apart causing a rattle and it telescopes up the exhaust to the engine and has fooled many a mechanic into thinking it was a rod knock.
With the engine hot, but turned off, take a small hammer and tap on the cats and see if they make any noise.
