KA24E oil pressure/pump

[Tristan Smith]

David, the only gasket you need is the one numbered 15066. I would change your oil gauge sender first before I changed any of the other parts. If you still get readings that you consider low, I would think about changing the oil pump.

I don't recall what my cold oil pressures were, but I don't think you are seeing anything dangerously low. Especially if you haven't warmed up the motor and rev'ed it up to see what you are getting under load.

If you do change the pump, take all the spark plugs out and turn the motor with a socket on the crank. Shine a flashlight in the spark plug hole of cylinder#1 and you will see the piston at TDC. Use the distributer and the timing marks to make sure that you are at the proper stroke.

Be sure to prime your oil pump before you put it on. Just fill it up as much as you can by pouring some oil in the holes (but not so much that it spills all over the place when you turn it at an angle to put it in).

See what Earl said about the distributer.

Looking more and more like an issue with the sender or with the wiring. Started the car up this evening and got 42psi immediately at idle. I don't think the oil pump would have magically healed itself overnight.

Let it warm up and then reved it to 4500-5000. Got 50 psi or so at those RPMs. The gauge seemed to get stuck at 40-50 as it wouldn't go below 40 at idle even with the car at operating temp. The weird thing is that when I turned on my electric fan to keep the car cool it seemed to jar the gauge and it dropped to about 25psi at idle. Definitely something flaky going on. I'll replace the sender and check the wiring.

I'll bring the spare oil pump with me to the track just in case, but I'm going to chalk this up to electrical weirdness. Hopefully that's the case. Thanks for all the help. See you at the track.

Glad it looks like a simple fix David.
If you dont mind, run blocker for the ITA CRX we are bringing up.
I know how wide a 240 can be at times!
See you guys track side.

I haven't driven since Labor day last year so I'm not expecting a whole lot. I'll likely be trying to keep up with that CRX. If I can run similar times as last time out and have somebody to race that would be a good weekend.

Have you seen the run group counts.
You will have plenty of racing to do.
