Yeah, your engine is scrap now mate...










best give it to me :wink:



Your certain there's good spark?
I had a similar issue with my CA when it was over fueling like a mofo, that was my own fault however.

You didnt do "work" in the bay just before the problem started did you?

well firstly my engine is over fueling, i get about 250-300kms a tank!

secondly, the only "work" ive done is drain and refill the cooling system then bleed the cooling system, and that was done a couple weeks ago and it was "fine" after that.

i must also add that my car has been running hot of late (so i havent driven it much at all lately and if so not far enough to let it get hot).
themostat works
radiator is fine
looking at getting a new water pump now as it looks like the water flow in my rad is not really good

any ideas?
i dont want to do anything further and possibly damage my engine...

if you are running a dicktator check your red wire thats in your harnes that plugs into your managment its a bit thick if im noy mistaken and also you need to check if your map on your managment is still ok heating up can be caused by timing hence i say have your map checked.

Too little fuel or too much timing advance will cause it to run hotter than it should. And that can cause detonation which equals bye-bye RB25.
