    I've seen these engine pre-lubers around for awhile and always wondered if they were worth the money. If they work properly they would be great insurance for an expensive motor. For those who haven't seen them, Its a pump that brings up oil pressure before the motor cranks over. They are about $450 for a pump, some hoses and a circuit board, but is it worth it???? Any opinions or has anyone used one?

    They do work and do what they are advertised to do. I just don't think that they're quite worth the money for most applications. You can already get well over 100,000 miles out of most engines without these. If you have a very rare, very expensive motor, then you should go for it. I can think of quite a few ways that I'd rather spend that money.

    There also is another alternative to the pump style pre-luber. That is the accumulator style that Canton makes called the Accusump. These are quite a bit cheaper ($185-$285) and won't wear out. You would also have the advantage of backup oil pressure in off-camber situations. Just go to <A target="_blank" HREF=http://www.accusump.com/index.html>http://www.accusump.com/index.html</A> to check them out.

    They are a very good idea, but you can make your own. Get an old distributor and remove everything but the shaft and housing. Weld a nut on the top of the shaft and install it in the motor and use a drill or speed wrench to turn it. It is extremely useful on motors with hydraulic lifters, spin the oiler then adjust valves before start up.

    DOH!! Maybe I should read the whole post.

    Rob, the pre-lubers that he's talking about are used each and every time you are about to start the engine. They pressurize the oil galleries before you hit the starter. The one you're talking about is used to get oil throughout a freshly built engine before it's fired for the first time. That's the reason for the big price tag. [​IMG]

    I dont think a pre luber or accumulator is necessary on a stock or mild performance daly driver.Its just one more thing to break and start to leak when off road. Changed regularly, modern oils and additives do a pretty good job of protecting the engine at startup.
    But pre- oilers do help if you are running a built high compression engine that has a high idle at start up. or if you have a expensive engine that sits a long time between startups or races, a pre oiler would be a good idea.

    Yeah, I agree, it's overkill on a stock motor, but something that would make sense on a rare or difficult-to-replace motor.

    Even so, if that's a big concern, a quart of slick 50 run through every few oil changes should bond to the metals and make startup a little less dry.

    Maybe if you let it sit between starts for long periods or something.

    Thanks for the info everyone! I'm gonna check out the accumulator sounds like a little added protection at a better price. I do have a rare motor in my vette and I'm working on a big block build up for the blazer. Even though the big block wont be too radical, after all the greenbacks, a little extra money to make sure its protected makes sense. Thanks again!

    Jegs sells the acumulators also. These are Moroso. The dulux model goes for 174.99 That's with a manual valve. To make it work like a preluber you got to buy the solonoid valve(another $99). Also the oil filter has a check valve in it to keep from back flowing when you shut off the engine. Not sure it would be healthy enough to handle 30psi backwards. You would also need a Adaptor ($25) for the oil filter so you can get the lines connected. Bottom line if you did it right your close to $$400 (Got to figure lines and your probably going to want to remote mount the filter). I think that the fact it stores the oil makes it a better choice than the pre luber. The pre luber gets it's oil from the drain plug I believe. If the sump is out of the oil then there is a chance the drain plug is also.
    You know you might just be able to build a pre luber with a pump from WW. Grainger [simle]
    Sure could buy a lot of good synthetic for the cash though.
