Just for the sake of argument:

How hard is to work on a LR3 engine?

Parts available, prices, ... can be done DIY (tolerances/tools are within hobby mechanic reach...) 

 

I bumped yesterday into a local LR3 for $3K, engine needs a lot of work or replacement, since they have not changed oil for the last 2 years... noisy and what not, bearings and some other stuff needs work I am sure ...

 

So yeah, i had some impure thoughts on getting me a project LR3 one day (not now though, but maybe one day)

 

So for all of you with a LR3 or similar engine, what is your DIY rating on this trucks?

Not scared of electronics, sensors or computers.

Thoughts?

I always liked the RRS better but seems to be the same vehicle with different shell anyway...

I have the sport - yes - same platform - the engines seem to be pretty reliable - good idea to change driveline fluids periodically - but overall not a lot of major issues. Suspension bushings will not last much beyond 60k ....

I didn't take engine apart - but I would first start with a flush and new (maybe high mileage) synthic oil - and inspect filter for metal debris and do used oil analysis to see what metal levels look like - before I'd start taking it all apart ). If sludge is causing lifters to stick etc. just cleaning it out might be all you need -

If it sounds like a diesel it most likely the timing chain and tensioner . If you willing to risk it i would get it for as cheap as possible if engine is dead not worth replacing

In general the 4.4 has been very reliable so I don't see many people doing big engine work on them.  Thermostat housings can crack, but you don't see a lot of actual repairs to the engine itself.  I haven't given it a good look as to how hard it would be to remove.  It may be easier to lift the body off - which actually isn't that hard if you have a lift to do it.  Colin might be the best bet for input on that as he's done a body off on his when he swapped transmissions.

Ah yes, I forgot about that but it is a known item.  Not super common but a possibility.  Of course anything is possible but I'd still expect to just start with general maintenance and go from there.  I don't know anybody who's done a full rebuild or replacement so I have no idea what the costs would be.  I'd guess you could buy a take-out engine for under $5K.

About $5K is what they quoted the guy for an engine replacement with 50K miles-ish.

Again, not going to do this one, but I just wanted to know what LR3 owners general feeling is about working on the engine, at one point or another I will find one too good to pass on...

On Monday I'm going to tear mine in part, to replace main rear seal.

At that time I'm also going to change the transmission filter and pan over to the new metal version.

I'm going to remove the driveshafts and service the front and rear differentials.

...and since I've gone that far I'll probably take a look at potentially rebuilding the transmission.

I'm sure that I will find other things to do while I've got it torn apart.

Sure....I'll just rebuild the transmission while I'm in there.  Might as well.  

 

That's taking 'preventative maintenance' to a new level.

Don,

 

Yes, you and I take the approach "don't fix it unless it is broken", and then proceed to break it so we can fix it ....
