His engine blowin up 5 times on the same EMS dosen't make sense either...

mechanical oil pump is controlled by pressure right, which is based off combustion,fuel, intake, timing and so on.. which is what a EMS does..

I'm not nervous about anything at the moment. I know what work and marksmanship has gone into my project and I'm 100% sure things are close to prefect.

 

Dont come at me sideways kid.. you dont know me... I post based off what I research, I'm not a freakin genius but I know enough to get around my car..

 

Huh!?
I could be talking out my ****, here, but I am fairly confident that the oil pump impeller is just spinning away and couldn't care less about the ECU, EMS, FCC, M-O-U-S-E. Like you said yourself, it's purely mechanical, so I don't think the oil pressure should be effected by your EMS at all.

 

so you sayin he had 5 faulty oil pumps in each engine that went bad?

 

5 faulty oil pumps?
No, not at all. I am questioning your logic in blaming EMS when he (allegedly) suffered oil starvation related failures. I don't think the EMS could control anything to do with lubrication delivery if it tried.

 

I was just sayin that the EMS/tuning could play a factor in some way of his past engines failures.. I'm not sayin that this last failure was caused directly by the EMS alone but it could have played some role in the cause. I'm not a mechanic but it just seems odd that he replaced almost every part on this build but still uses the same EMS system.

EMS controls ignition and timing yes.. "all lubrication is deliver via pressure"

 

"marksmanship" on a motor would certainly cause a drop in oil pressure and cause oil starvation. Thanks for solving the mystery!!!

 

glad i can help..

 

any pics of your engine bay?

Some of your parts in your sig look tempting

 

NYqeen, the oil pump discharge pressure is a result of rev's (RPM) the oil pump has a small internal reileaf valve that opens at 90-100psi. This may have stuck open intermitantly as it lifted at high RPM and not flowed enough oil/pressure to the big ends??

This may have been a possibilty?

 

That’s understandable.. I have no doubt in your reply, this is the reason why on my build.. I was particular in upgrading both my oil and water pumps on my engine because I knew these parts would be critical in my build.

 

What I meant is that your luck mighty get you on of broken/defective parts, improper machining, misassembly..etc. in every one of your builds.

 

Severe detonation can pound the rod/main bearings out, opening the clearances and lowering oil pressure. Usually detonation leaves some evidence in the combustion chamber.

Preignition on the other hand can destroy parts with no warning and nothing but metal soup left behind. It could also destroy bearings, lowering oil pressure.

If timing was going out of sync for any reason (flywheel slots not machined properly, bad crankshaft positon sensor, weak sensor signal or an internal ECU issue) hard parts can be damaged.

I'm not placing blame on any of those, but there are other factors that can cause issues that aren't related to a faulty part or the installer.

 

I will get some pics up later today and will be putting up FS threads for the parts as they are removed. All of the cosmetic parts on the motor will be for sale also. PM me if you want to know about specific parts.

 

+1. I'm really interested in a teardown if not satisfy some curiosity but perhaps shed some light.... I have doubt in the teardowns done previously by the engine builder but maybe that's just me. If Cass and Blinkierfluid agree to it, I'll be happy to donate time, beer, and bring my D90 to take plenty of hi res shots of the process and share them with the community. I'm no mechanic but I'm good with a camera.

 

chris i willing to donate 9mm, .40, .45, .223, .308, 12ga n what ever else i can find in my safe to give this motor a proper burial.

 

Thanks. I have enough VQ blocks to make a whole room full of coffee tables and end tables. Sorry I will miss you guys at ZdayZ and the airstrip this year. Hopefully next year though.

 

Possible. I have been there for at least two of the previous teardowns and they just looked like really high milage engines with lots of wear. No obvious signs of detonation and no missing or broken parts

BTW, I have the plenum off and meth system drained and preped for removal. Maybe a teardown and part swap party... I will provide beers.

 

 

Really sad to see this happen again Chris.
