Did you see the part about servicing the turbo with fresh oil after an oil change?



"After servicing the engine or turbocharger, ensure that the turbocharger is pre lubed by adding clean engine oil into the turbocharger oil inlet until full. After pre lubing, crank the engine without firing (engine/fuel pump stop out) to allow oil to circulate through the full system under pressure. On starting the engine, run at idle for a few minutes to ensure the oil and bearing systems are operating satisfactorily. "



Do we have this oil inlet?



Found this under Parts and Service and then Know your turbo section of the web page that Catcracker linked.

Its a failry standard practice to fill the the turbo full of oil before you run the truck. I just use a funnel and fill it up, then put the oil line on and start the truck.

So you have to disconnect an oil line to fill it up?

Does it drain out of the turbo when the engine is shut down?

How come in three years of surfing this board I've never heard of that one before?

Kinda like refilling the wifey's Windex botle. Pull off the sprayer to fill the bottle.

To a certain extent yes However there is allways oil present.

I dunno

this is one reason cummins say if one of thier engine has sat up for more than 30 days your should keep the engine from starting up and crank it until the oil pressure registers. but in reality if you burn your turbo up its no big deal b/c you can send your core to peirs and get an upgraded one for $350. so i am not going to go to the trouble of filling up my turbo after an oil change but it is important that as soon as you get done changing your oil to restart your engine. now when i get my twins on my new truck you bet i will prelube my turbos. and for those with $1500 turbos i would l prelube also. on reminder guys when you crank the truck after changing oil dont crank and leave the truck make sure it has proper oil pressure b/c it can blow a seal out on the oil filter and you will run out of oil in a hurry ( although rare it does happen)

I don't think I have heard of this before either. However, there have been discussions about making sure that the oil filter is pre-filled so that the turbo doesn't have to wait so long for oil.



I know I have never pre-filled the turbo - I guess it would be interesting to find out how many do.

I've installed a couple of rebuilt turbos and the instructions specify to pre-lube them just before start-up.

I've always done that to new turbos, and new engine start-ups as well... only logical IMO.

(As a matter of fact, the instructions that United Turbo (NH) sends with a rebuilt unit specifies a NEW oil feed line or there is no warantee coverage. Not sure that would hold up, but they are serious about insuring proper oil supply. )

FWIW

I don't recall reading anything about it in the service manual. And, I bet when you have your oil changed at your local Dodge dealer, they pre-lube the turbo for you ..... NOT.



If they don't require it for warranty coverage, it can't be that critical. Now, putting in a new turbo sure, I can see that.

 

[Spooled-up]

The service manual states to run the truck until the temp reaches 140 degrees before you drain the oil. While you're changing the oil, most of the oil drains out of the turbo anyway as Tool Man stated. I wouldn't think there is any difference between starting the truck after an oil change as compared to starting it after sitting overnight. In either case, oil drains out into the crankcase and is replenished upon startup. I can definately see the need to fill the oil filter though. Starving the turbo for oil for the time it takes to fill that filter can't be good.

I bet for every 1 turbo that gets pre lubed by removing the oil line after a oil change that there are 500,000 that dont get it done. That is primarily for new installations where there has been no oil at all. Also a good reason to use synthetic oil.

 

[Jetson]

The reason some turbo companies specify a new oil line is that carbon can build up in lines that are subjected to high temps. As I understand it, most people do not replace the oil lines when doing a turbo change on our trucks. BUT, I would not mess with the oil line just because of an oil change. I ruined a turbo on a Merkur because I didn't replace the line.

Tool Man, remember when we stuck the PDR35 in your truck a couple years ago that goofy guy from the left coast insisted on pouring a little oil in the oil feed hole before hooking up the line?
