So in the process of getting my eg k24 going, i see the little oil can on the dash illuminated.
Had it always been on?
I dont know
Is my wiring bad?
Maybe.
I decide to put a sandwich plate and sensor on
Did I mention no oil came out from the filter or oil sensor when i removed them?
Gauge is at 60 until I turn on the car ...it never leaves 0
Think its worth looking at the pump?
Is it more likely the engine?
I knew I was taking a chance when I pulled the engine from this ride

OOOF, the block just cracked,
coolants everywhere.
Back to the junkyard

2nd time arounds gonna be a breeze
fingers crossed
I was wrong,
The block is not yet cracked....let me explain

So I start the vehicle, the oil light is on, I hear a terrible metallic clanging noise, i turn off the car and see the engine coolant dripping out.

Oh Im fucked.....not so fast.

On closer inspection coolant is leaking at the intake base.
The rbb base fits bolt pattern wise, but there is an intake port(?) on the far right that doesn't seal on the R40 block

Cant use the oem r40 base and intake because of hood clearance issues, Gonna try an RBC

Looking under the car I notice that part of my exhaust that id poorly mocked up fell when I started the engine. (the clanging sound).

So thats a relief, but I still have no oil pressure.
Pulled the oil filter, turned off coils and fuel pump, cranked it over several times in an attempt to bleed air and build oil pressure.......nothin.

Trying to find time to pull the pan and look for obstructions, might as well have a look at the bearings for signs of overheating while Im there.

Got a lot of reading to do til then

Anything else I should be on the lookout for?

Could you please explain it a bit more clear your shortened thoughts? Even it is old, I am sorry, I didn't read it.

Ended up having to swep from the original k24z3 oil pump to the k20 type
Could you post the exact engine setup. There are a few things to take care of when swapping to the K20A2 pump.

No worries!

My oil pressure sensor was reading zero at the gauge after startup.
Its due to me moving the oil filter location and not putting on the k20 oil pump.

Apparently the 2 pumps use different galleys to move oil around

I know that the oil chain guide is usually swapped out too but the original seemed to spin just fine. I guess im gonna find out

I suppose not...My oil light went off in seconds with the k20 pump
Oh, sorry to read this. Good you got is sorted and solved.

I wrongly assumed swapping pumps was optional on this build
It is an option. There is no need to swap the oil pump in a technical perspective. The cause it is done is because of the higher revving range of the K20 pump gear wheel, which has a lower gear ratio and the higher efficiency in the higher engine speeds. But baseline, the stock oil pump of the K24 is also in a K24/20 Frankenstein possible, just limiting engine speed to 7800 rpm or a bit more and adding some more friction horses into your setup.

I still don't get the idea why you had issues, the sandwich plate issue, you described, is just an user related issue, has nothing to do with the oil pump which is installed. The point is, once you swap in a K20 oil pump, then you have a list to work down before installation is finished and properly working.

I also thought it was optional on my build, it wasnt.

I cant leave the stock oil filter position and clear the midshaft, I had to relocate the oil filter
There was NO oil reaching the oil filter prior to swapping the pump,

I don't believe the sandwich plate was to blame(not that im free from user error. plenty of that around here)
Oil light went on with original pump, went off in seconds with new pump. I also checked the filter and found that oil was reaching the new filter location ( never touched the sandwich).


Did you read the article i directed you to?

"We also encountered an issue with the oil filter flow routing. With the stock oil pump, the oil flows through the elaborate balance shaft housing to a passage in the block to the oil filter on the lower side of the engine in the bed plate. With the K20 oil pump the oil flows up the block to the filter on the front of the engine in the middle of the block. "

The k24z3 is an odd duck


"you have a list to work down before installation is finished and properly working. "
Besides blocking the oil jet, new pump chain, guide and tensioner, what am I missing?

How does Honda do it on the TSX 🤔?

You need to block the oil passage...

Besides blocking the oil jet,
...wait, you block the oil squirters?

-My guess would be different half shaft/different mounting`points
the rsx half shaft only mounts at 2 of the 3 connections( not ideal)

-Other than the one I've already done shown in the photo above?
..

😂😂😂
-Not sure how we got so turned around

Uuuuuups, I missed that it's a Z3 style block. Sorry for that, I didn't allow this in my Synapses to connect together, because who the hell would like go through all that challenges with the Z-platform and I studied your pictures not much as I was still thinking about a cracked block and issues around it. Sorry for that circular discussion.
