Oh lord its an axx, I've had quite a bit of experience with that engine.
So who rebuilt the engine?
The person that fixed it should of been able to reflash to stock tbh.or know someone who can.
They should so be able to trace where the oil & fuel are mixing, there's not many places they can tbh, I'm finding it difficult to understand how whoever rebuilt couldn't trace this issue.
If its overfueling, how's it escaping past the rings so much, is it sticking to the cylinder walls & thus the rings roll over & drags downward, which is why I'd either look at these or other parts that share oil & fuel supplies to see if its mixing via other means.
Hi again buddy,
Long complicated story re engine so here goes.
The engine that let go after the map was an axx. My tech told me the oil was heavily contaminated with fuel resulting in failure.
So I was chatting on one of the forums about it and an engineer joined in, we got talking about things and he said he was selling his recently built axx engine due to a new project. The engine was no expense spared with integrated engineering rods, bhz head. It was running a ko4 and had a revo map It had apx 5k on it at the time. So after much negotiation we agreed a price on the bare engine as I couldn't afford the ko4 setup at that time. As the guy is based in Aberdeen and I'm in West Sussex he shipped it down on a pallet. At this point he advised It would be a good idea to get my existing turbo checked over, which I did and consequently had rebuilt as it was in such bad shape. I also had my existing injectors cleaned and checked by r tech, a new pcv, dv, hpfp, follower, turbo back miltek with sports cat and all alloy S3 intercooler where added. The plan was to get as much in place ready for the ko4 at a latter date.
Once fitted everything was and still is running the same as the previous engine. In the cold it takes a couple of turns to start, on idle when cold the revs drop and rise, its a tad jerky when driving for the first minute or two then it settles down.
Also the throttle is very on or off, extremely sensitive Al of the time.
This was the case on the previous motor staight after I had the map done.
Also as I'm now extremely paranoid about oil contamination I have been checking like a hawk and yes it's still there.
So the same issue but on two engines.
Plugs are good no smoke, no codes. Could be borewash?
I've been in constant communication with the engineer who built the engine and he's been great, trying to work through things with my tech down here, nothings to much trouble for him. He even checks in if he hasn't heard from me to see how things are he wants to help but other end of country.
As a matter of safety the car has been off the road for months now until I can get this sorted.
It needs a stage 2 anyway to tune in all the new mods but I'm reluctant to drive from Horsham to
R tech in Nuneaton as it is, hence me wanting it flashed back to stock.
Sorry if I rambled on there I just wanted to give the clearest picture of the situation lol.
Hope its clear enough.
Thanks again for your input and time buddy
