I have a 05 5.9 and it's been sitting for about 2 months now while being worked on here and there. The oil has been drained and sump pan has been off. Before I start the engine, I want to take the extra step and prelube the engine bearings, oil passages etc just in case any dirt has found it's way in or any little critters. The truck has been on asphalt, but in a big storage unit.

What are the options to get oil through the whole engine without an electrical transfer pump to push oil through? I have been told a few different ways, but someone chime in who has actually done this prior to starting engine. Thanks!

UPDATE 7-8-2011: I went by Napa today. The parts guy I have dealt with showed me this Posi-Flow fuel filter. The psi on these things aren't much. Here is a link to the pump with technical information. He said I could use it to pump the oil out of the bucket into the engine through 1/8 fitting by engine cooler. The cost is 54.00.

I think it's a good idea but not sure how to do it on these engines. I have always done it to the gasser engines I have built.

I'm sure some one will chime in on how to do it best.

 

Indeed my friend. I think it's good insurance and after 248K miles with no mechanical issues except the front and rear seals and having to sleeve the crankshaft, I can't complain. I bought the truck new in 05 and have changed the oil and fuel filter at same time at 7500 miles. A few times I cheated, but very up on maintenance. The injector pump is still kickin great too.

Where do you rock crawl at?

 

The only real way to do it is with some type of out side pressure source as the oil pump is driven off the case. When I rebuilt a gas motor that had a similar setup, I used lots of assembly lube and then cranked the motor over with no plugs to reduce the load on bearings. You could pull the injectors.

 

do not worry about it. we have 138 pieces of equipment and trucks with diesel engines in them, some like pavers and brooms may set for a year or two in the field, some special trucks may set longer.

 

Assuming that you pre-filled the new oil filter, I would treat it just like a fresh oil change. Crank it until it just tries to start and turn it right off. Repeat six or seven times to get the oil filter completely full and some oil pushed through the lines, then start it. Repeat if the oil pressure hesitates to come up.

 

My truck sat for 2 months and all I did was start it. Oil pressure came right up (real gauge, not fake gauge).

But if you want to crank it and not fire it all you have to do is pull the 3 injector harness plugs off the valve cover and crank it for 10 seconds or so, it will fill all the passages with oil.

 

Thanks guys! Appreciate the feedback. AH64ID, a friend of mine told me about taking the harness plugs off also. I plan on doing that. This truck has given me a great return on my money so figured I would go the extra smile.

 

I would tend to agree with what most said about no worrying about it.

If you really want to, I have done a prelube on a brand new Duramax. You need to find an oil passage that has a pipe plug in it. There is probably more than 1, but for sure the top of the filter housing has 1/8" plugs.

The tool I used I borrowed from the GM dealer. It was little more than a plastic plunger style hand pump that screwed into the top on a clear plastic 5 gallon jug. Fill the jug, hook the hose up, and pump away.

The tool was a GM (Kent Moore) service tool that had adapters for all different kinds of engines.

 

Robert, I have been looking for one of those guns to no avail. The update on the posi-flow pump will work with the 1/8 fitting on filter housing as you mentioned. Just not sure that little pump will suffice. Thanks bud!
