Hello Chaps

So I've been looking for a WH Jeep Grand Cherokee for Ages. (like a couple of Years)

Ive had my heart set of the 5.7 Hemi, but looking sound there are Absolutely Zero in my Area, closest is Nearly 300 miles away.

Theres loads of the Crd very close to me. my question is Would i always regret buying the Diesel when i started it up every time i got in to it?

What do you think?

I've just bought a 2005 diesel, to replace our workhorse petrol/lpg 4.0 Cherokee.....and yes is the short answer.

Luckily its a 3rd car.......

Thanks, my brothers got the 4.7 v8 with lpg, which is where I first got the idea.

I live on and island that gets cut off my the tide twice a day and so it would be used for going through the water every now and then! How would the petrol hold up with being dunked in water, I've always been told diesels are better for wading? Not that I'm planning on doing it everyday

Petrol you need sparks to run. Wading can cause ingress of water, thus losing sparks. Diesel is compression, no sparks, less risk of stopping.

I have a 3.0 crd WK Overland, and so far in the past year or so I've owned it, it has been great.

Performance is not much worse than the petrol, but the economy is far better. I think they are 215 bhp as standard, but a remap will give around 270 bhp and a slight improvement in economy. If fuel costs aren't a consideration then go petrol, if they are, then CRD may be the way to go.

I've seen 30 mpg on a run, but generally motorway driving gets 25-27mpg and town driving 21 -23 mpg.

Not on a CR Diesel, highly dependent on electrics.

Thanks bud, Yeah, if i did end up buying a CRD i would be getting it mapped pretty much Straight away. The Economy doesnt bother me that much as i only do between 100-150 miles a week.
i know what alot of people think about LPG but if i could find the Petrol one with LPG that would be a Gem, Great sounds and good Economy, My brothers had got LPG on it and he's had it for 5 years or so and he swears by it.

Im not sure if i could go to my brothers and park it next to his and not feel slightly jealous when He starts us the V8.

To be fair, you can't beat the sound of a V8

I briefly ran a 06 5.7 hemi and it was fun, instant grunt and comfortable on long journeys. The fuel economy was laughable but then what do you expect a 5.7 v8 pushing over 2 tonnes to get small tank too so not long range. I picked it up with about 50k miles did another 15k in 12 months, at service I did the major so spark plugs and all and later on it had a bit of a screech on bumps so needed new bushes and then the egr went as well as the door locks. Mind it was a cheap fix most times so not a costly car, but I fancied more refinement and a better ride so I traded in for a x5 which is leaps and bounds better but no v8.

Would I have another?

Maybe but I would rather have a new model Cherokee like the hellcat jeep, if I was going to be going crazy might as well go all in.

Yes I'm sure it was as that's what the fault code kept coming up with and that's what I replaced. After replacing it was all better.

Does anyone know of any 3.0CRD buyers guides, links to them, or what to watch out for? Looking to get an 05-07 GC Overland 3.0CRD in a couple of months.

Who are reputable companies for remapping these?

Check out the WK GC section on Jeepforum.com

As for mapping, Green Diesel Engineering hot tune comes highly recommended but it's expensive. If it was my cash I'd check out a local tuner who has experience with the Mercedes 3.0 CRD. The engine is used in lots of different applications.

I've got a 300C with the same engine which I bought back in November. Admittedly it is very leggy, but I've discovered myself some of the pitfalls of the 3.0 CRD engine and things to watch for.

From what I've been reading up on forums, the engine has something of a 'quirk' whereby oil is vented out of the crankcase breather under pressure and in to the air intake. Not a huge issue in itself, only that on earlier models of the Jeep/300C the rubber seals on the intake hose allow this oil to leak out of the joints. Directly underneath where the intake hose meets the turbocharger is an expensive box of tricks which operates the swirl flaps. The oil leaks onto this, wrecks it and then the engine goes into 'limp home' mode. To replace it involves considerable dismantling.

Potentially more ruinous is the fact the same rubber seals are used on the oil cooler, which is a small heat exchanger unit buried in the 'Vee' of the engine. I had this fail, and it manifested itself in an increasingly serious oil leak which was impossible to trace. Took it to my tame mechanic who basically had to remove everything from the Vee of the engine to get to it including the turbo, air intake plenums, swirl motor, fuel injection system etc. Even though his labour rate is a fraction of main dealers, the bill still made me wince. To top it off, the oil had at some point found its way in to the alternator, presumably when the oil cooler failed. This is apparently another common issue. I've had the warning light coming on and off for a couple of weeks now, and yesterday it completely died on me. So the car is once again immobile on my drive until I can get it booked it. Oh, and the alternator is a bh to get at smile

I believe later models had different seals fitted to the intake pipe and oil cooler. The original seals are red in colour. http://www.crdsite.com/turbo-seal-oil-leak-fix.htm...

I'm no expert but these are just some of the problems that can happen, and unfortunately they all happened to me. If you end up test driving or viewing one, look underneath carefully for oil leaks. Ensure you drive or at least get driven in the car, and afterward switch off the engine. If you see oil dripping from underneath it, walk away. There's loads of information out there. Don't be put off, just buy carefully. Check any service history to see if the oil cooler and swirl motor has been replaced.

I own a 2001 4.0l petrol LPG runs ok but low on power but pulls a trailer ok
Have owned a 1996 4l a 2001 4.7l V8 that dod 238k before I got rid of it to get a 55 plate with 110k 3.0 CRD and wouldn't touch another one if you paid me
So many problems exhaust flex joints on mainifold break and flood the car with fumes
Banjo bolts on turbo come undone and flood the engine with oil.
Oil seal went on main shaft
Alternator blew
And to cap it all I found out from a leading Mercedes Chrysler director that the modified sprinter engine can very easily jump a cog on the timing and shaft your engine somewhat spectacularly as mine did. Hard one to diagnose on these as would you believe it throws up other faults such as Blown Turbo module . So crack a piston and a head and and and

Aaaaargh
If you have any Jeep issues suggest you contact my guys who look after my Jeep as are Gurus TCJ Tom and Nev 01604 722700
But as I said I still bought another jeep and will go back to a V8 as soon as have the money to do so
Happy driving guys
