Here is a link to some info on a pre-luber. http://www.redhummer.com/myhummer/preluber

type up preluber on your search engine, and read the whole article and info they provide, 80% of engine wear occurs during this first ten seconds of start up, this has been tested and proven, any engine that isn't run 24/7 will benifit from a preluber. www.espperformance.com

I think you are correct about engine wear at start-up. But the pre-lubrication systems I have seen send oil only to the turbocharger. I am uncertain how pumping oil to the turbo before start-up will affect valve train, rings, crank mains etc etc. It seems to me that on most (all?) turbochargers the oil returns directly to the pan- and in that case, the preluber will affect the longevity nothing beyond the turbocharger bearing.

mike , i respectfully disagree, look at the mains and cam for instance, they acuatully float on a bed of suspended oil when oil pressure is up, when there is no oil pressure there is no bed of oil seperating the bearing from its case, they are under extreme pressure and if it wern't for high oil pressure, lets just say we would be taking longer walks. as far as plumbing the system, they are set up to go into the oil filter arena, not directly into the turbo, oil pressure anywhere in the system will bring it eventualy into the turbo.

If you do not use your truck as a daily/weekly or every other day driver, then it would be a good idea to prelube. Oil will stay suspended in your engine a long time before it finally goes back to the pan. So even though every time you crank the engine, you do wear it a bit, the amount of wear is very very small but significant (% wise) when compared with normal driving.
A good Prelube is a good idea for peace of mind and that is always a good reason to do it. Kinda like insurance... No one plans to crash, get hit, whatever, but its nice to have insurance if and when it happens... Got the cash... go for it... just my .02
Oh yeah, and don't the turbos spool up AFTER you hit the pedal hard? By that time, they have been lubed...???

no its reinforced rubber its rated for something like 250psi. as far as draining the oil the adapter that is screwed in place of the drain plug has two taped holes on it one for the hose and one for draining. however they do offer a quick conect that i put on the output of the pump so when i drain the oil all i do is disconect the hose and pull it down a little and stick it in the old steel gas can that i use for oil and turn on the key. the pump pumps it out of the pan. ( i wanted to check to make sure that it was geting all the oil out so i opened the plug on the adapter and it barly driped.) i have not had any problems with leaks but abrasion is a posible problem. i took a look at the hoses on my truck and i found that the way i routed the hose caused the hose to sit aganced the frame and wore through the outer coating on the hose i plan on replacing the hose when it gets warm. next time i will put hose in a protective covering. if you would like i can post pics

I think you are correct- And I think we were talking about two different systems. The pre-luber system you and others mentioned obviously pressurizes the entire system, making my points irrelevant.
The systems I am familiar with supply oil only to the turbo immediately after shut-off. These systems address bearing failure caused by dry spin-down of hot turbos and have no impact on the rest of the engine.
I am not certain which system JMorton was looking into.
Sorry for confusing the issue.

TYME CHASER, Which ports on your filter housing did you attach the output of the preluber too? You live in Mt Prospect, DesPlaines for me.

instal note do not mount to the fire wall (very noisy in cab)
as far as how it works its ok i think i damaged the impeller when i forgot to prime the pump before i installed it. so it takes a little longer to presurize the system than it used to.
it is nice to have oil presure before i turn the key. especialy in the winter
the reson i looked at this sistem is becouse i have the 6spd and my father and brouther have a habit of leaving the trans in gear whan they park it. i did not want them to foreget that there was a turbo timer on the truck and turn off the key and dump the clutch and have the truck lurch one way or the other, or even stay running and drive off. with this system the engine is off but there is still oil runing to the turbo

Do you have any pics you could post showing the connection back into the motor?
