Crankin the Chev...

[Tenrocca]

Once the ECU come back fromthe tuner she SHOULD start.

Exciting!

[Rebel1]

Tenrocca, did you go thru the recommended pre-oiling procedure?.

Cheers

[Tenrocca]

Ummmm...no. Whats that? Is that bad?

[Rebel1]

I'll send you a link later....just a manner of feeding pressureized oil into it for the first start.

Gotta go do a job.

[Rebel1]

Mate, I don't think the holden factory would use the procedure but it is a recommendation by GM for the first start of their crate engines.

Send me an email rebel3 at tpg dot com dot au and I'll send ya a document.

[Rebel1]

Better yet...here is the same in a link:

Hmmmm GM service wank factor!

What's wrong with cranking it over numerous times without firing or doesn't the GM pump push enough at cranking speed?

If the old motors could be oil primed with a drill I'm sure cranking off the starter isn't going to be too much different - tell me I'm wrong!! Its not as if it's a race engine be gods!

Better buy some ear muffs too so those delicate ears don't become soiled when the motor finally fires into life!!

[Tenrocca]

Thanks for the info Les I would be curious to know if our fellow darksiders went to these lengths on first start?

I would have thought any assembly lube used when they put these together would protect it enough till the oil got circulating. Anyone know how long should it take for pressure to build up?

hehe...headers only for first start - You should be able to hear it down there.

[stephen low]

More than the time it takes to turn it off again should be sufficient - that's if you've pre-lubed up - anyone for KY?

But seriously, I'm listening!!!! Nope can't hear a squeak.

However really seriously, with an engine pre-primed, any non-movement of your pressure gauge seconds after firing is not right.

Fill it to full oil level, crank it only numerous times and check your gauge during cranking. Should get some pressure even during cranking!! After that I'll wait for the roar.

I think it is just insurance to prime the oil pump and get immediate oil pressure upon firing.

The local tune/engine shop does this with all new engines be they ford or chev.

I'm gonna steal their patented pre-oiler when I start mine. It consists of a weed spray from bunnings...you know the 5 ltr spray thingy with a air pump on top. Bunnings sell them as cheap as chips for spraying plants.

The engine shop has removed the spray nossle and fitted a small tap/valve on the end of the hose.

They claim they can get up to 40psi of oil into the engine to ensure oil is right thru an engine. They crank the engine without plugs for a short while.

Anyways...cant harm I spose.

Tenrocca,

We started the LS-1 in our Cobra for the first time last week.
We rebuilt the motor ourselves, and lubed everything thoroughly during assembly.
We didn't see much oil pressure on the guage while cranking, but as soon as she fired - loads.
Priming the pump is a good idea if you have the time and materials, but I believe it's a luxury.
If you consider how "Primed" an LS-1 is when it's been sitting idle in your garage for 6 months - I think you can safely assume that the pump will prime itself.
From our experieince - you aren't doing enough revs while cranking to see much pressure - mind you it looks from the video as though your battery has more grunt than ours as your motor is turning over a bit faster than our was - so you might see "some" pressure.

Note to self - buy a new battery !

[sideshow]

there is good and bad things with doin this or not

a newly build enigne usually gets vaso put in oil pump drive

ive had some jap engnes where no matter what u do u cant get oil press unless u start it

so on used engines im not sure what way is best
it doesnt take long to do it anyway

but i wire up and i am usually the first person to start the enignes i wire up and have done over 500 i guess and only twice ive had probs

lexus v8s are so nie to do u can get oil thru to top of heads on some of them just by turning engine by hand

holden enignes run bloody low oil pressure anyway from factory

first time i saw the factory specs on an ls1 ecu for oil press i wasshocked

anyway on 2nd handengines i usually just turn the key and bang she goes

hey hewey i got the plugs for the brake level sensors

[Tenrocca]

Had a look tonight Les - that plug is impossible to get to without removing the alternator with where i have it mounted - would you know if there are any other options\spots?

Cheers
Andrew

[Rebel1]

Nuh mate...got no more ideas than whats printed on that sheet.

Any others which may be there would be hidden behind headers etc etc.

[stiffy]

Rebel1,


Thanks for the heads up! It makes sence to prime a new engine.

I saw a mechanic friend of mine take the plugs out and spray WD40 down the cylinders and crank it for a few seconds. This seemed to do the trick


The DAYTONA will fired up this Month so its very topical


BIG STIFFY

[Tenrocca]

Would this work - Just hook into the return line on the remote filter - and pump through that. Should be easy enough?
