Oil pump that pumps oil before start up?? Help

[djrizzle]

I hope someone can help me, I heard they make a oil pump of some sort that pumps oil to the top of the engine, before start up, has anyone heard of this??

any companies that make this??

 

My friend's brother has one on a viper but we don't know what band. I need it for my chevy truck.

I have seen them but they are only used on high performance vehicles and are pricey. If you have a stock engine in your truck its to really worth it. I have a ZR-1 Corvette with 460 rwhp and use Mobil 1 with no problems.

'Pre-Luber' I 'think' is the name of the aftermarket kit. It was popular back in the 90's but I've not seen them advertised for some while. I just looked real fast in the JEGS and Summit Racing catalogs and didn't see them.

 

Might try a Google Search for 'Pre-Luber' and see what pop's up.

 

Good Luck.

My guess is it won't be family friendly

I looked in to this when I bought my 1995 Suburban. After much research I decided that there was a better solution.

 

I don't know if it still works, but back then the computer had a special mode for clearing a flooded engine. You used to be able to hold the accelerator to the floor when you cranked the engine and it would inject no fuel whatsoever. I found that I was able to use the starter to turn the engine over slowly until the oil pressure came up.

 

The technique was equally as effective as a pre-luber and ultimately more reliable. I decided that the cost of replacing a ruined starter was no more expensive than installing the pre-luber. And unlinke the pre-luber, a starter failure wouldn't lose all of my oil or clog and ruin the engine.

 

I also used Mobil-1 in that engine from the very beginning. I sold it 10 years old with 157,000 miles on the engine and it was as good as new. I usually reserved the starter trick for times when it sat longer than a weekend or whenever I changed oil. Somewhere near its tenth year and 150,000 miles I finally replaced the original factory starter so I think I didn't do it too much harm. (I think it was the selenoid that ultimately failed.)

 

I wonder of the new trucks have this feature?

I was going to say that, but you beat me

djrizzle, I have not searched it at this time but I am sure the pre lube systems are still avail. I have never seen an "oil pump" that acutally pumps before the engine starts but I have seen a small tank which contains presurized engine oil with a solenoid. When the key is turned on, it simply opens the solenoid which allows the presurized oil to travel through lines and into the oil passages in your motor. It takes only a couple of seconds for it to prelube the engine. Once the engine starts, it pumps oil back into the cylinder and the solenoid closes the valve and retains the presurized oil in the tank until you start the engine again. It is a great idea and will eliminate almost all start up wear. You just have to decide if it is worth the money and effort to install.

 

Mark, I do not want to be disagreeable but would question using the starter to pump oil into the motor before start up. I have built a few "hot rod" engines and have always been told when you crank the motor for the first time, you really want it to start as soon as possible to get oil flowing quickly. I can remeber specifically the instructions that came with a Comp Cam that warned against extended cranking periods and how it could cause harm to the cam, lifters, bearings etc.

 

Please understand, I could be wrong, but it would seem that you would want the engine to start as quickly as possible so the oil pres would build quickly and send oil throughout the engine. Any thouhts or comments on this?

My last truck was a 1995 K2500 (7200 GVW) fleet vehicle that I bought from PG&E in California. I let it go with 185,k miles. I know that no one ever prelubed this engine to start it. I did a timing chain when I bought it and the wear was not exceptional--everything looked good and I did the chain as a precaution. The truck ran great and burned no oil and everything seemed tight (I drove it across the country with 178,k on it).

 

I would not bother with the prelube unless you have some very special circumstances that require it. Just start the engine and don't touch the gas until you have at least 20 PSI on the guage (the guage is slow, you will have close to full pressure by then).
