Priming turbo after fitting
- Thread starter DJH
- Start date
I’ve looked through the engine manual, and this is what it says about fitting a new turbo, so that’s what I’m going to do.
Install in reverse order of removal, observing the following:
– Observe tightening sequence for turbocharger ⇒ page 215 .
– Renew seals, gaskets, O-rings and self-locking nuts after removal.
– Fill turbocharger with engine oil at connection for oil supply line.
– Hose unions and air intake pipes and hoses must be free of oil and grease before installation.
– Secure all hose connections with the correct type of hose clips
(same as original equipment) ⇒ Electronic Parts Catalogue .
– After installing turbocharger, run engine for about 1 minute at idling speed to ensure that oil is supplied to turbocharger. Do not rev engine immediately.
After new components have been installed (engine/short engine, cylinder head, camshaft housing or turbocharger) the oil pressure control must be set to max. pressure for approx. 1000km if the function is available in the engine control unit. This will compensate for the increased friction during run-in of new components, and a better transport of wear related particles is guaranteed.
– Connect ⇒ Vehicle diagnostic tester.
– Switch on ignition.
– Activate oil pressure regulation ⇒ Vehicle diagnostic tester,

You haven’t mentioned why you are fitting a turbocharger.
If it’s because you’re renewing a failed unit make sure;
1. You’ve accounted for and recovered any missing metallic parts from the original that may have entered the induction system.
2. Proved the oil feed is clear, crank the engine without starting and check open end for oil flow.
3. Proved the drain lines are clear, in the case of a catastrophic failure remove and purge.
4. DPF condition, excessive back pressure will act against the oil feed.
Without an adequate pressure drop across the feed and drain there won’t be adequate flow for lubrication / cooling.

It kept having an intermittent actuator fault. The turbo place said it throws that fault when the VNT gets sticky. It was getting on, as the van has got 176000 miles behind it, so I’ve changed it along with the inlet manifold, EGR, and a new charge air cooler, as the mounts were broken or nearly broken on it. I had the DPF professionally cleaned a while back, and I’ve got new oil feed and drain pipes.
I also removed the sump and cleaned out the oil pickup strainer as advised by the turbo refurbishing place.
I think that should cover everything.

Simply fill the turbo oil inlet with clean engine oil leave for a few minutes then refill, start the engine but don’t increase revs by much. The turbo will hardly turn (in turbo speeds) at low engine loads and speeds so won’t get hot or bothered. Don’t start up and go to full beans or put the engine underload for a little while i.e. minutes
