Interesting spark plug..

What do you think? Detonation?

Can anyone recommend a proper tuning company who knows Omex backwards? I have a little turbo charged Abarth pushing 300 bhp and I need someone who really knows their stuff not a backyard tuning/remap firm. It's a track car.

Just found out this is the only one of the four like this. Guess that would indicate either a bad injector or a wiring fault to the injector?

Hi Peter, will do have owned several MG's so would love to see your place.

The plug was on cylinder 2 and it is oily and so were the other three. There is no sign of the engine burning oil at the tailpipe though but we've had a weird oil leak under boost which we're struggling to track down. Thought it was coming from the breather but hard to pinpoint.

We're going to take it all apart and have a look I guess it could be valve guides but the engine has just been rebuilt so struggling to see how it could be mechanical at this point.

Last time we had an issue it had cracked the block. That was running 1.8 bar of boost its down at 1.5 bar now.

Engine should be apart later this week will post some further info. Thanks all.
