My engine is still out of the car, but almost ready to go in. I want to prime the pump and just check a couple of items before the install. (Timing belt and timing are already set)

I thought about just turning over the engine with the starter; recheck my timing and prime the pump at the same time.

Will the starter turn enough RPM to prime the pump and get some oil thru the engine?

 

so you want to run tha starter on the engine with the engine on a stand???
You could just as well remove the spark plugs and turn the engine over by hand the oil will start pumping out the oil cooler hoses

 

My bad, brain fart!

Its been a long day under the car

Thanks

 

Remove the plugs? just spin it

Prime it when its in the car just before firing

You can do this on the stand if your then ready to start it up (like the same day) but if your like me one day is spent getting the thing in the car, the next spent connecting it and the 3rd is spent starting it up.

Just make sure when it is in the car you spin it via the starter for a bit to prime the entire engine.

 

Thanks Ryan, your right. At my pace it will take me a week from stand to ready to start. Plus, I am installing a Stage III from Murph which will slow me down somewhat.

I was also wanting to recheck my timing after turning it over with the starter and would like to do that now. BUT...

I have turned it over by hand several several times (without oil) and rechecked the Timing. But for sure I don't want to turn it over with the starter without oil. The engine as all new lifters, rod bearings and rings. I really want to get some oil flowing before I rotate much more.

 

I would install the engine and get it running first and break it before bolting up a SCer

Put a thousand or more miles on it first. Thats what i would do anyway. If not that then i would at the very least get the car running in its stock configuration and making sure its right before bolting up the SCer. If something's wrong there are just too many variables you have to sort through.

 

I also have been thinking along those lines, but here is the issue.

With the stage III, I will be installing 42lb. injectors. My old injectors are for the most part trash. AND I don't want to go thru installing the injectors twice.

Will the car run in its normal stock state but with the 42lb. injectors?

If so, I might call Tim when he gets back from vacation and have him send ahead the injectors and proceed.

 

Injectors arent that difficult to pull out and install, those wiring connectors are a bitch though!

Still, i would strongly suggest you getting it running CORRECTLY in stock trim first. Fact of the matter is something will need adjusting or you will find something you missed. Just get it running first. Break it in for a bit then you can go back and install the SCer.

swapping injectors a second time will take all of 2 hours (if your slow) Thats not a good enough reason for me to bolt everything up and hope it works perfectly the first time.

 

Cranking an engine dry to prime is the worst thing to do. Most initial wear is on start-up. It's best to start engine and let it run with oil pressure. There are primer systems available that use a resevoir to pre-lube with pressurized oil. You can also use less expensive products like this.

What are you talking about? Your telling me that with a fresh engine, with a sump full of oil. That cranking the engine with the Fuel cut off and the ignition disabled is going to cause damage? Sorry please explain this one.

How else do you suggest priming a 928 engine when its in the car and the belt is already on?

 

If for some reason there is poor or no oil pressure, yes damage can result.

 

When I took apart the engine on the 88 I used assembly lube on all parts, dropped the engine in, filled with fluids and oil, removed the plugs, crancked the engine a bit to get oil into passages and started the thing up. I've had no problems since. You'll be fine. I do agree with the idea of running the engine a bit before putting a SC in.

 

ok so yeah if there is a failure then yeah damage can result, but the main question has to do with priming an engine and you suggest that cranking the engine to prime it is forbidden.

 

It's your main question. Too nice of a day, going for a drive.
