Priming oil system

[JustinGTS-T]

Hey everyone,

So I had the engine apart over the winter and just got it back together last night. I have installed a new OEM oil pump, anyone know of a optimal method of priming the engine? I have not found very much info besides "disconnect ignitor and just hold the key, several times until you achieve pressure" this just seems sketchy and I'm unaware of any pumps I can rent.

Thanks for the help!
Justin

is this important? i didnt even think of doing this.. ill be starting my engine around the end of may, so ill be watching this thread

^+1 i dont think this is entirely necessary but i would bet it would help your motor. I knew a guy with a spoon crate motor in his honda and he had like a pressurised oiling system. the jist of it from what i understood was that it flowed oil through your motor before you started it and kept oil flowing through after you turned your car off until it cooled down. ive heard something stupid like 90% of the damage to your motor is done when starting and turning your car on and off but i dont know if this is true or not.

Make sure not to press your clutch either. A good habit to get into regardless of a new motor or not. Defiantly prime the the oil by disconnecting the CAS and turning it over for a bit.

Your starter turns a lot slower than an idleing car. It will take a bit for the oil to fill the pump/filter/lines and finnally start lubricating.

If fitting a new turbo (upgraded turbo), it's common practice to prime turbo with oil before installing or like said in above post, disconnect CAS and crank engine.

[got_boost!]

Replaced my oil pump myself as well, and done turbo upgrades. Always just disconnected the CAS or the ignition amplifier and gave her some cranks to help flow the oil and load the oil filter. Cranking is perfectly fine, but you need to be careful how long you crank for. If you turn it over and over again for too long, you can burn out your starter fairly easily. I always just give it about ten cranks, then let it sit for a few seconds, then another ten. Repeat until you're satisfied you have enough oil in all the important parts.

Is un-plugging the CAS commen practise for Oil Priming the RB. I had read somewhere not to do it, could cause damage. But this is the Internet afterall.
I always did it by running it out of fuel(Fuse removal) before storage or any work I was goin to do. Then cranking it without the fuse.

yeah I think its not that important.. Though priming it over to get oil pressure won't hurt.. This can sometimes take up to a minute.. By that time your battery is flat. Starting it with the crank angle sensor on.. firing will get oil pressure within seconds.

If you have a journal bearing turbo you need to disconnect the crank angle sensor and wind over till a good 100mm + comes out of the oil feed line. Then connect that to the turbo. prime again till oils pissing out the oil return. Connect and start. =primed= if this is not done the journal bearings will burn out within 10-30 seconds. Then the turbo is had it.

Not press your clutch? Doesn't the clutch have to be pushed in for the starter to turn...

[Super_Dude]

If you push the clutch, it pushes the flywheel, that pushes the crank into the unlubricated thrust bearings.

[DarkCaporaL]

And our cars dont have a neutral safety switch (or whatever it's called) so the engine will turn without pressing the clutch.

i put assembly lube all over my bearings, so im safe. but still, ill turn it first without the clutch

[Rblove26]

it is a very good idea to prime the engines oil system before any start after sitting for a long period of time, did it just last weekend when i started my up for the first time this spring, however i disconnected the fuel supply as to not load my oil pan with fuel that is not being burnt, disconnecting you ignition system works to but you will most likely still be putting fuel into the combustion chamber, running down past the pistons and wiping any oil splashed up on the cylinder walls plus filling your oil pan with fuel. And if your battery or starter cant crank your car for 10-15 secondes then its probably time for new, its not like your cranking a diesel over or anything lol

is all of that necessary?? wouldn't just cranking it over a couple times push oil threw the turbo aswell?

[craftz]

After I installed my rebuilt turbo, removed plugs, fuel pump fuse and turned it it over till the low oil pressure light went out. Didn't take long at all. I did not know about clutch, I'll keep that in mind.
