Thread: TD6 Turbo Replacement

Mine started this about 20,000k's ago. Local LR mechanic said best to get the turbo rebuilt.. be 2.5-3k though

Keen on the idea of importing a new one and fit it myself. Everyone says to stay clear of the garrett copy.. Would like to know why.

RANGE ROVER L322 TURBO TD6 3.0 - NEW - LR006110 - £449.99!!!! | eBay

Be about $750 landed.. gotta be worth the risk!

Not a fun job to replace the link to the following video clip is 1 of 3

Are you sure it needs replacing ? might only be a leaking oil seal, line or the vacuum pump . I would have a good look first and then find a turbo specialist and get their opinion before buying an exchange turbo.

Thanks for the quick response guys.
Camo, the 1k is for a genuine Garrett, I did see the cheaper ones but thought that for the extra I might save having to replace it again too soon ?
Laurie, I saw those videos, hence the query can it be done from underneath. We are pretty certain it is the seal in the turbo not the supply line, hence the need to remove and recon or replace the turbo. Given the local costs of recon then the new wins.

I thought the standard turbo was a Garrett unit, with the LR Oval marked on it !

Quote from a UK BMW specialist turbo rebuilder.

" The main cause of BMW turbo failure is the condition of the engine oil, a diesel engine will produce a lot of soot like gases which make there way into the oil via the piston rings in the engine. Theses gases are vented back into the engines induction system via the crankcase breathing system (EGR valve also sends gasses etc back into the engine exacerbating the problem ) in theory they never stay in the crankcase long enough to contaminate the oil. The problem is this process occurs constantly when the engine is running and eventually the oil gets contaminated to the point where it can no longer lubricate the turbo, once this happens then the bearings in the turbo start breaking apart which causes the compressor blades to spin off centre, this will cause the turbo to whistle, BMW 330d and 530d suffer from this problem a lot and its always good to repair it once you here the turbo whistle.''

Replacing the crankcase breather filter regularly and blanking the EGR valve will prolong engine and turbo life with the benefit of a few hp and use a little less fuel. A win, win situation !

Haven't done a turbo on a TD6 (M57) but have done a few on TD4 (M47). With the TD4 the rocker cover doesn't need to be removed, There is 3 grommets in the air filter box under the air filter. remove these and the heat shield under it and you can unbolt the turbo from the exhaust manifold.

Hmm I wonder if thats the whistle on overrun that mine makes or a different whistle?

Adrian

what are we listening for?

Mine whistles under heavy throttle with a trailer, and it has a little overrun noise - other than that can't hear it. It's not changed since I've owned it, I assume it is ok. whats the tell tail for failure?
