LS3 prime engine ?

What did you guys do to prime your LS engine ?? I have been reading a number of guys purchased pre-lube tanks to prime the engine because they felt the "GM" instructions were not adequate on priming. I mean pre-lube tanks really ???

Re: LS3 prime engine ?

You will get many diverse opinions on this. I donít use a pre-luber but wonít bother sharing my personal method because I know forum experts with more credibility will disagree...

Latest GM instruction now specify use of a pre-luber as far as I know.

Bottom line is make sure you have it primed before you start it.

Re: LS3 prime engine ?

This is directly from the Chevrolet Performance catalog.

PRIMING THE LS ENGINE
If youíre used to building classic Small-Block and Big-Block engines, youíve probably used an electric drill or similar tool in the distributor hole to drive the oil pump and prime the engine prior to start-up. LS engines donít use distributors, so engine priming must be performed in other ways. First of all, fill the oil pump pickup with oil when assembling the engine. That will ensure a quantity of oil is in the pump when the engine is started for the first time. Also, disconnect either the fuel supply or ignition system when itís time to start the engine and allow the engine to ďroll overĒ for approximately 30 seconds. That allows oil to circulate through the engine without the engine running. Removing spark plugs will allow the engine to prime faster with less load on the bearings. Then, reconnect the fuel or ignition and fire up your LS engine!

Thanks Simon, this is the exact GM instructions I am talking about that is NOT adequate as deemed by many.

The cost of a prelube is not that much. ( check summit) I use on my ls builds as its a little better way to go.( No one argues that pulling the distb and priming is not the best way) that being said ( was in auto parts and machine shop business for many years) many customers that bought engines or had engines built never primed other then cranking ( I don't recommend on a performance motor) and don't have issues. Final thought, I have watched/ been involved in etc many many engines and it can be surprising once in a while how long it can take a engine to pump oil completely through the system hence my preference for priming all my own motors.. Cheers

This exactly how I've done every LS engine including built LS7, LS3 crate and LSX. I disconnect the ECM and then crank until I see OP on the gauge. Hook up the ECM and start the engine.

Re: LS3 prime engine ?

Thanks John. I have been reading guys complaining they have not seen any oil pressure on their gauge while cranking using the GM method.

Wow, pricey Don !!!

Looks very similar to the OTC unit which costs less...

I canít imagine which pre-luber you use makes any difference. GM always specifies pricey Kent Moore tools.

I just looked on Summit's web site, they have a few for much less.

Some of them donít include adaptors so you have to figure out what you need to connect to the LS pressure sender port.

Your hardware store carries odd size 16x1.5 mm metic to SAE adaptors for a dollar? Awesome store. You wonít find anything like that around here....
