VCU and crankshaft breather

Recommended Posts

hi guys

Just been looking through here and seen a few common problems with the freelander 1 which now has me worried :unsure:

Mine looks to have a leak from the rear diff, (not had it on ramps for better look yet) so would I be right in saying this whole unit needs replacing or is there a gasket that can fail where all the bolts are on the back of it. I have a few symptoms as follows :

I seem to have to ride the clutch/ put more revs on when reversing and turning.
The outer tread on one of the rear tires is worn.
(This may not be related) When i turn left at junctions etc there is a loud catching sound from nearside rear wheel area

I will try the one wheel jack up test tomorrow, if the result is that i can not turn the socket does this mean the VCU?? is shot and £££.

2nd the camshaft breather..

I would rather replace this as it sounds devastating if it blocks up. So is this an easy task and does all the air cleaner cover etc have to be removed to replace it?? whats this BMW conversion cone about. TD4.

I'm proper paranoid now after being on here haha

many thanks for any guidance in advance.

2nd thing 1st: You mean crank breather, also called PCV (Positive Crank Ventilation) or "Valve - depression limiter" is easy, if fiddly, to change.

1st thing: VCU is this bit:

And is not the source of your oil leak but is probably the reason your tyres are scrubbed. £225 from Bell Engineering is a small price to pay to prevent it from exploding your drivetrain. Or remove the propshaft complete and drive in front-wheel-drive only.

The oil leak from the rear diff is entirely fixable, most likely pinion oil seal. There is a crush tube that sets the preload, I'd suggest reading the RAVE manual before deciding to tackle the job yourself. The method is to mark the nut & count the turns when undoing it.

well chap sticks I've had the cretin up on the ramps with a LR specialist and the VCU looks brand new .. all the bolts that are replaced with it are all new and shiny looking compared to everything else under there .. plus a fair bit of cash has been spent on it in the past with all new brake lines/hoses clutch etc etc phew..

the rear diff is only weeping oil so I have cleaned it up to monitor how much it does leak when i next inspect it ... as I know its a bit of a job replacing the oil seal.

The scuffing noise I am hearing is carp in the rear brake drum (drums have a bit of corrosion about them, and was quite hard to pin-point the sound while being in the drivers seat) so I will whip them off and determine the conclusion of them at a later date ...

So happy days .here's to more ASBO driving, smiles and fun with the landy haha FORWARDS!!!!!

Yes, but that one is the standard type, there's a cyclonic BMW one (part number B11.12.7.799.367) that doesn't have a fluffy element to clog up. Either will do, the original type just needs changing at service-time (you can buy just the fluffy filter part if you look round).
