range rover 3l diesel chugging

[sam80quattro]

im sure ive read before that there is a few on here that deal with land rover/range rovers...
a mate is having problems with his 51 plate RR and i said i would ask on here.
first started when he had rear brakes changed, drivers side is sticking on, the garage then replaced brake flexi. still same problem, am i right in thinking they have shoes within the disc for the handbrake?
then it overheated whilst driving on a dual carriageway, got home and left it for a week.
started the car and all seemed fine, although he did loose water, topped it up and seems fine apart from pulling away, it chugs, as if its misfiring, but it runs fine and if you floor it, its also fine, just part throttle or even no throttle aslong as you lift off the brakes it does the chugging/juddering. hard to describe it, like abs pulsing but on the throttle.
the pipe onto the inlet didnt look seated right so i undid the jubilee clip and moved it and there was air coming out over and sounded like exhaust, is this egr? and is that normal?
finally took the oil filler cap off and there was steam coming out, fired it up and there was quite a bit of steam constantly coming out, its definately steam, theres no oil smell and it evaporates on the rocker cover...

Don't quote me but I think the handbrake will be a transmission brake on the rear prop. I'd look to the caliper assy or maybe even the weird brake pump thingy given that the flexis didn't do it. If you google the chugging theres a few people had the same problem and theres a fair few helpful people on landyzone.
Our P38 overheated towing a few times and it turned out it was a warning the waterpump was about to let go which it did a week or two later on a romp up the motorway.

Just realised its probably an L322 if its a 3litre so as usual my post is probably irrelevant apart from the landyzone bit!

i'll certainly try and check the waterpump see if theres any signs of a leak as they normally do leak prior to failing dont they? or is that just a vauxhall thing? always remember cavaliers doing that for some reason. i'll also get a look on landyzone. thanks

It was the plastic impeller that fell off our waterpump so the only water loss was as a result of the cap letting the pressure out of the system when it boiled up. Just hope the chugging and the overheating aren't linked cos that could be a head gasket problem.

Does range have a tandem pump to create fuel pump and brake servo vacuum. Seen these cause lumpy idle on vag could it link your brake and rough running. Pretty sure range would have transmission hand brake. However the fact you.re using coolant and condensation in oil might suggest head gasket

The L322 has the handbrake shoes inside the rear discs and if not set correctly can warp the rear discs very quickly.

I would suggest replacing rear discs and shoes.

There is a few write ups on the net if you do a search for the adjustment procedure, from memory it is wind them up fully and then back them off 8 clicks.

As far as the chugging...
Needs plugging in to diagnostics, common failures with these are:
Air flow sensor
Crank speed sensor
Fuel pressure or fuel pressure sensor
Leaking injector seals
dead/dying injector.

and a few more
so get it plugged in to someone that uses testbook they are pretty acurate for diagnosis on the L322

cheers for the advice
