priming oil pump

[DsM KiD4]

which way is better to prime the engine? Through the filter housing or actually taking a drill to the oil pump sprocket? id rather do the oil filter housing way but can someone compare and contrast??

also.... If i choose to prime from the oil pump, does the clutch and flywheel need to be removed from the crank? Or can i put my car back together first??

thanks!!

On a fresh build, there are two ways you can do this:

1- (Preferred method) With the timing belt off, attach a socket / drill attachment to the bolt on the oil pump sprocket and turn it at high speed for a good 30 seconds with a drill. This should sufficiently get oil moving through the entire system.

2- Once everything is ready to go, start the car up. Do *NOT* disconnect the MPI fuse, spark plugs, etc . . . and try to prime the system by turning the engine over repeatedly. Just fire it right up. You should build ample pressure within 2-3 seconds of the engine running. If not, kill it . . . because something is probably wrong.

As always (with any newly installed oil pump), be sure to pack the oil pump with Vaseline. This will keep the gears and housing protected and lubed up during that crucial first start.

And yes- this can all be done with the motor fully installed. It just may be a bit tricky putting the timing belt on properly for those who have not done it yet.

Hope that helps!

so just to clarify.... i can put the clutch and tranny back on the car and still spin the oil pump with no problem? just makin sure..... thanks!!

I'm not an expert but as long as you have it in neutral when doing it you shouldn't have any trouble. Someone correct me if I'm wrong?

If the timing belt is not attached(which it shouldn't be in the first place) the oil pump won't spin anything but itself and perhaps the rear balance shaft if it's still there. Neutral/in gear won't matter.

When oil comes out the banjo bolt/plug(2g) on the head for the turbo oil feed you know the pump has been primed.

As stated above you are not going to have the timing belt on so the pump will spin freely you dont need to have it in neutral or anything.

how long can a rebuilt fresh engine sit after priming it? i ran out of "warm" weather and trying to find a nice place to store my motor. thanks for the tip tho.

So long as you leave fresh oil in the pan, I would assume it could sit as long as a regular vehicle could and still be fine. But with how easy it is to prime the oil pump, I would just do it again after you get some more warm weather (if that's 3+ months from now).

 

[Grimis]

yeah i might let it sit with out the timing done, havent done it yet, then when it gets warmer prime again and then put the belt on.

 

[Mr Peepers]

I don't know how you could resist the temptation when it's so close...

 

[Grimis]

i still need manifold, turbo etc, every thing that touch's or is involved with a turbo i need yet, so no rush till spring.

Yet, you'd think this would be the more easier way to prime things up without having to fuss with all of that other stuff...

Perhaps more easy if the belt is already installed . . . I would still tweak the process and NOT crank the car over with the MPI fuse removed. If you have pushed oil all the way up to the head, there is no need to be cranking the car like that. It'll build pressure almost immediately upon startup.

Beter safe then sorry. Take the extra step and turn the engine over without spark and fuel to make sure It build proper amout of pressure.
