Misfires and flashing CEL

I was trying to determine if it was a fuel issue by seeing if cylinders started firing when i sprayed it in (they didn’t)

But they looked wet, smelled a little oily, and a little like fuel and the tips were dark. looked a little like carbon to me but that could have been the sea foam loosening up deposits from the head and piston.

When i installed the berus they looked perfectly grey/tan and i’ll also attach photos if i can figure it out

So just spit balling here.
I would expect the plugs to be wet because of the Sea foam.
I would expect them to smell a little like fuel because the fuel/air mixture was not burning due to no compression.

Smelled a little oily hmmm and looked a little like carbon.!!!!
I would expect a little carbon if those Cylinders were getting a little oil in the fuel/air mixture when the engine was running.
carbon=burned oil.

Was your exhaust ever blueish or whitish or not looking right???

Only when the aos failed. And then the replacement failed two months later. Nothing visual out of the exhaust, and i would have seen it because it’s a “race” exhaust.
There’s always a film of oil in the intake from the AOS. it wasn’t like that when i bought the car (it was bone dry inside), but i could never quite figure out why it never went back to having zero visual oil in the intake after replacement. maybe just an inferior part to the original i suppose, but good enough to pass.

My intake always has a little oil as well.
I get the bit of blue exhaust on startup but just for the first few seconds.
My plugs always look like they should though.

keep us posted

I’d rarely get blue on startup unless i parked on a steep hill and even that was rare.

hopefully i’ll find out something new tomorrow, and really hoping it’s something good

They found nothing in the gas tank. Looks like it’s just a really bad coincidence. they want $500 to do a bore scope and i just don’t know if it’s worth it at this point. Don’t know what to do

You could buy a scope and do that yourself for around 20% of that cost or maybe less.

I could, but i’m going to have them do it. i showed them the form racetrac sent me which just states is it in your professional OPINION that the gasoline caused the problems. i’m hoping a borescope will help them come to a conclusion about what happened. even after explaining what happened with the car they still think it sounds very bizarre. Holding out for anything good. If they can’t explain why the engine would blow like that, to me that points to one thing, but then again, i might be a little biased
