A little update, I've changed the fuel filter and fuel pressure regulator and it's still running filthy rich. Put in different maps and still nothing.
Today we were about to load it on the car trailer to take to Niall and my mate thought he'd check the intake. We cranked it over and oil and fuel starting pissing out through the turbo intake. Turns out that the whole engine is full of fuel and it's pissing out the pcv. What can cause this much fuel entering the sump?
I don't think it's a stuck injector as I bought them off Blake Gloyn who cleaned and pressure tested them. Could it be that my old fuel pressure regulator was stuffed, increasing rail pressure causing a leak somehow?
I took it to a mechanic friend nearby and he's going to drop the oil and start it up again and hopefully diagnose the problem but if anyone has any ideas I'm all ears.

dmn thats some serious issues. have you pressure tested the cylinders? ive had these types of troubles when rings let go. on mx bikes. if ts not emanage related.

Not as yet but I'll get that done. I don't think it's rings as it was running perfect before I replaced the starter. I'm hoping the 20 year old fpr couldn't handle the 023 fuel pump and has just constantly flooded the engine letting fuel past the rings. I'd imagine that even healthy rings would let fuel pass through, what do you think?

blown rings from my experience with dirtbikes = no starty, too much fuel in the cylinder after a few kicks, compression lockup sometimes. fouled plugs from fuel. and fuel in the sump. bits of valve chipped of.
Running excessively rich with unburnt fuel will put fuel in your oil.
Flush oil, fresh plugs and check emange properly. Even with 650's and an ultimate it will foul injectors in about 10 seconds without any settings changed in the emanage ultimates.
What size injectors? is it an emanage ultimate? if so is the temp sensor wire connected?

Mods are all in my profile but I've got 550s and and emanage ultimate. I'm thinking your right Christian. I've tried to start it many times which is probably why so much fuel has come through. It's made it into my intercooler which suggests to me that it's been over fueling while running.
Pretty sure the temp sensor is connected but I'll get them to double check.
Sebastian, Disconnect the temp sensor from emanage. This made mine lean out alot at idle especially when cold. Also have you connected your PC and looked at any maps or changed any settings?

Sebastian - I'm wondering if yours has the similar issues as with my tune. Have a look at the pic and you'll see I had to pull heaps of fuel to get it to run properly. The injector correction was strange as well, but I ended up using what Cihan advised. I think you can do away with the correction altogether and just add or remove fuel as normal. Have you got a wideband hooked up? Try pulling fuel till it starts to idle OK (if it will still start that is) +++ jpeg +++ 318512 +++ Upload +++

My original tune had the car going great. I have a wideband and it was running a good safe tune. A little rich perhaps but not too bad, it did stall once from memory but that's about it. Do you think the fact that it was running on the rich side could cause that much fuel/oil to piss out the pcv? I've never seen anything like it, my cooler is full of fuel/oil.

I thought the map sensor line only sat high on the block. I checked the map sensor from the top of the engine but didn't realise that there were lines near the starter. I have pulled the starter out once the problem occurred and couldn't see anything lose mind you The car was on stands and not on a hoist so I couldn't really see too much. Also if the map sensor isn't functioning wouldn't it come up on diagnostics? I only got ect --

When i accidenly knocked out the line to the map sensor my car stalled and died and wouldn't start till i plugged it back in. I don't know about diagnostics but if the car hasn't started properly 0 pressure makes perfect sense to the map sensor which thinks that the car isn't started so it shouldn't have vacuum.

Sorry guys, I left out an important piece of the puzzle. When we took the plumbing from the cooler to the plenum the car started and ran quite well. It was still blowing smoke but that can be attributed to the oil/fuel sitting in the exhaust etc. We had to stop the car after 10 seconds as oil and fuel starting pissing out the pcv. Do you think the emu might not have the corrected injector settings right due to the fact that I have a higher rate fuel pump? I know that the fpr should keep the pressure the same but after 20 years it might not be up to the task. When I get the oil change I'll try to set the emu with bigger injector settings.

Yeah mate, that's what I posted earlier. Sorry if it was unclear but my cooler is full of oil and fuel. That's why I'm now leaning towards leaking injectors. Seems like to much overflow for it to just be from it running rich.

Ok, dropped the oil and started the car. It's idling fine but blowing heaps of smoke. Highly likely that all the seals in the engine and turbo are gone so I've basically spent 5000 gs plus only to destroy my car. I can't even part it out for anything if the turbos are gone so it's a very dark day in the car modification game for me. Fingers crossed the turbos are okay and I'll chuck in a 1.5j but I think they are gone too.
It seems either my fpr or the injectors were the culprit but it's a little to early to tell. The way things are going there might be a fresh piece of arse on the kings cross wall to fund my rebuild soon haha.
