R34 Gtt, Engine Problems

[Cartsy]

Hey guys, i've got a R34 GTT, thats running a rough and i've got no clue as to how to fix it. Its your standard Rb25 Neo, but with aftermarket intercooling tubing, a pod filter and a HKS G176 BOV, recently i've changed the oil, sparkplugs, rocker cover gaskets and half moon seals.

Firstly on a cold start, it starts up and idles perfectly, but when re-starting it up ( Warm start ) the car won't continue to run and will only run if I hold the accelerator on for 5-10 seconds at 1000-1200 RPM.

Secondly sometimes when I'm accelerating at a normal speed, i hear popping sounds from the engine bay and I loose a considerable amount of power. The only way that i've been able to overcome this issue is by revving the engine over 4000rpm and then it goes away after a little. I also get this same issue at the top end of my revs, its almost like i can accelerate to a certain point and then it begins to pop. Its like the engine can go harder but is being stopped by something.

Thirdly, My check engine light comes on after about 5-10 minutes of driving. My dad and I found that my turbo had melted my O2 sensor wires, and still after re-wiring it, the check engine light still comes on, so I have no clue as to what to do with that.

And lastly i was wondering if its normal in turbo cars to get oil on the inside of your inter cooler / turbo / intake tubing. There is a decent amount oil along the sides of the tubing that's got me worried.

Any help would be appreciated, Cheers.

Put a stock bov on for a start.

Did it just start happening or did you just buy the car?

Oil is pretty normal to build up in tubing and intercoolers, but hard to say how much you are referring to. If its not pooling up and is just on the walls don't worry.

Hey guys, thanks for the quick response!

Yeah, I purchased the car about 2 months ago, and the pooping sound has occurred more frequently over the last couple of weeks but Its always been missing power at the top end of my revs.

So the car runs "fine" when cold?

Do you have anyone that has a spare cas you can borrow?
