C16XE transplanted in my Corsa, which was originally a 1.0 12v. Since the conversion has been done (about a year ago), the car has been misbehaving in the most odd way.
Starting from cold, the car starts and idles fine. Take it out a blast, and it's fine. Continues to idle well, no problem. The problems start once the engine has heated up.
The first time you put the foot down and bring it above ~4000rpm, the MIL illuminates and all hell breaks loose. The car will either idle at ~2000rpm, will hunt about 300~600rpm, or will die completely. The car has stalled before with the MIL extinguished, but that's a rare occurence.
The engine performs fine and pulls well for a 1.6, so doesn't appear to be suffering from the MIL.
We've tried the 'paperclip' trick and all that's flashed up is "12 + 12" (i.e no fault found), even after the engine has been driven for hours with the MIL on. Trying to pull the code with th engine running causes the MIL to flash steadily at a rate of about 2 flashes per second.
Things that have been replaced on the engine:
Lambda sensor (two of)
MAF
ICV
Coolant temp sensor
Upper inlet manifold
Coil pack
ENTIRE engine wiring loom
ECU
Earth strap direct from engine loom to neg on battery.
The problems only appear when the engine is warm, but sometimes even when fully heated, the engine will run perfect. Will idle fine, no MIL and pulls well.
Anyone got any suggestions before I fill the bores with sand and crank it til the battery dies?
Alllllsooooo.... The engine started playing a new game tonight called 'flicker the oil pressure light at high revs'.
The oil has been checked and it's pretty much at the top of the dipstick, it only appears when you cane it. I've suggested blocked oil pickup or dodgy pump. If the PCV system is blocked, would excessive pressure cause the oil pressure light to come light on these engines?
