I'll be doing this on my true racecar build, automated of course (cause lazy). Not on the Mazda though, bit of a pain in the ass getting it set up right for that unless extra holes drilled and tapped into the filter housing or plate or whatever. Falcon will be dry sump though, so no worries there.

Im also curious about what draining the fp housing will do. That plug makes me curious like it was designed for the drain and changed after production maybe? If you do it, im interested if the lobe sees increased wear.

I think what you are saying is oil feed, i think is oil drain. There is a little hole in the cam cap that is tied to bearing oil feed. So it looks like its designed to fill with oil and drain out that top hole, through the housing and out that bigger hole in the head. If you look at that hole in the head closely youll see what im talking about

Patent info doesn't include housing IIRC. Unless there's a separate patent.

Thanks, I have that document already, I was looking for the engine docs

I am not sure what is being discussed here at this point, last I checked things were being modified in the pump to help keep it clean now you guys are talking about draining oil.

Me personally do not believe I would modify anything to do with the oil system for the pump as noone has ever had issues with the stock setup and Mazda engineers know a fuck of allot more than we ever will.

With that said I cant read through all this banter, were there any conclusions made on your physical modifications, last I had seen you were doing many things and tearing the pump down almost daily.

littleloogy

So, what your saying is you want more fuel pump mods that no one will ever use? I almost blew @Enki;'/s fuel rail with some of these mods... We all figured out a better way to run 100%E without fucking with the fuel pump. This thread is now about Waco ideas that will benefit our platform. But we do have something fuel related in the works... But for now, oil drain and why that's there is a head scratcher...

No that's not what I said. You basically answered my question, which is where are we on this project and you just said basically fuel pump mods have been abandoned and you have another solution? I was trying to catch up from where I left off, but there is allot of random talking going on(hence oil drain).

Please link me to the other solution.

if you guys read the FSM you will find that drain is there to use before removing the pump housing, drain it before removal to reduce the mess; however, I have never removed my plug and I just let the oil drop into paper towels and such.

In the FSM you will find this in the pump housing removal steps.

EDIT: I rather clean up the mess instead of dealing with a potential leaking plug after removal

the solution is to use Royal Purple DEXOS oil and Redline Si-1 in the pump. Although with IE internals I think the Si-1 is not necessary. loogy's testing is ongoing IIRC.

doin good, nothing exciting going on.

Maybe you can teach us something about phantom ghost in our engine bay... You ever find it? D?

If it makes you feel any better I have started getting some random knock, bad thing is I'm still running lots of E

I first noticed it a few months ago. I was seeing less then 2 KR. Now it is in the 6's. It's so random, I have not been able to catch it on the data log yet.

Umm. That would be a zoom zoom boom son.

I was thinking that at first as well. But now I am leaning towards a VVT failure. I tried zeroing out the table thinking my VTT could be causing the noise. But I still get 10 degrees of registered advancement. I assume something loose?

I am all game for a build, but I need to ask for educational reasons. If this was a ZZB What would cause a such a random knock? I am talking about one episode during a 2 hr drive... I assumed a engine on its way out would knock more frequently.

Cracked ringland could do any number of weird things.

I would stop expecting the worst and check small stuff first. My intercooler shroud was causing me random kr up to about 3.5*

littleloogy

Hope for the best, plan for the worst. Either way, it's been a few years since I have done any leak down/compression tests. Should do one anyway. Who knows, maybe 30,000 miles on E has finally taken its toll.

That's likely something external causing the registered knock. You can run a leak test to confirm good rings and lands.

Went over my engine bay, possible mount issue again. Thinking about getting new Passenger, Transmission, and Rear motor mounts. . Tired of this shit.
