Anyone on here know anything about them? just bought a CRD and trying to gather some info on it.
 
Common rail diesel?
 
Here you go in no particular order
Check the plugs on the fuel filter housing for signs of overheating. They will suck air when they leak and run poorly
They tend to soot up pretty badly if driven conservatively. Don't be afraid to open them up from time to time.
Repeated glow plug failure in one cylinder means the head gasket and/or head is failed
Check the intercooler and turbo related silicone boots for tears and open areas where boost can leak. The aftermarket hoses are way better than OEM.
They require many special tools to do timing belt related work FYI. Pins to hold the crankshaft and camshafts in place.
The alternators have an overrunning clutch on them that sounds like a death rattle. It's just the pulley/clutch though

If I had one, I would remove the throttle valve and clean like crazy behind it. Also clean out any soot in the EGR tube as it gets caked with it.
When you are satisfied with it, reinstall everything and unplug the MAF sensor at the airbox. My understanding is this will disable the EGR function and will all be stop the excessive soot build up
 
I had one of the liberty CRDs for a short while. I ended up crashing it avoiding a dog on the highway :rolleyes:. Mine was an 05 and I'm not sure if it was year specific, but the wiring to the rear anti lock brakes would fray and stop working. Easy fix, but I just didn't get around to it the 2nd time it happened.

If you plan to get a tune from GDE or whomever, you'll probably want to upgrade to the euro spec torque converter, as the US spec is maxed out at stock power. I really liked the motor. I typically got pretty decent mileage and it could pull pretty well for its size.
 
First lesson:

to replace the water pump, the timing belt has to come off. So, guess im doing a timing job. Leaky water pump.

Ting belt replacement requires some special tools to lock the cam and crank in place. The cam sprockets don't key into the cam like every other engine does.
Just an FYI

from what i undertand, 5 and 6mm drill bits can be used as pins. ive looked into the kits. they vary from simple pins to elaborate jigs to hold the gears in place. no real recommendation of one over the other from what ive read.
 
I've used vice grips with the valve cover off on an unfinished part of the cam with safety wire down to a VC bolt on some timing belt motors..
