That’s ridiculous! I have 4 cans of the stuff here and will use it the next time I take my car out.
BTW when you said you tightened your IM bolts as much as you could by hand.... really? Was that after the initial torque sequence or what was your process? Like, gorilla tight? I’d really like to look at putting studs in there, but I’d be afraid to crack the IM screw bosses.

I went gorilla tight by hand and I did it the next day again on a cold engine.
Ok guys I ran another bottle of bg44k fuel cleaner and just looked at 3 pistons.
they are almost brand new.this stuff is amazing!
I'll be changing my o2 sensors in a few weeks to have everything fresh also.
here are a few pics!!! Wow unreal results.
Unreal! Great photos. Many people say a fuel system cleaner is unnecessary if one uses good gas but this is truly amazing to see and proof positive that there are additives that can clean combustion chambers.
Also, it's interesting to see the material erosion on the crown. I expected to see more generalized material loss as opposed to the deeper veining here. Ironically some carbon in the veins likely protects them from further erosion.
Question: when you ran that bg44k stuff, did you just daily drive it until the tank was empty or is your car mostly a track car? And does that stuff change the octane rating much?
I'm fairly certain the previous owner never did this on my car so it's prolly not a bad idea at 35k... Just wondering if it's a good idea to throw a bottle in the tank before a track day or could I be putting the engine and/or other components at risk?

I would run a bottle a tank before you track it and let the track session burn out the rest of the carbon left over.
It does not affect octane and you cant tell the difference with the stuff in the tank.
So..... to do it right, it should be pulled. Can I make the leap of faith and believe that the Weistec catch can will prevent or at least slow this down from happening again?
Few things that were changed and not sure what caused the carbon build up.
1 took out the oil catch can (had warranty work done)
2 ran silver colder plugs for about 3500 miles
3 took out stock air boxes and put on row/carbonio that caused long term fuel trims at idle to hit 38-45 on both banks.
4 ran a few tanks of e85 but that was literally a day before looking at the cylinders.

Sooooo you removed the one thing that prevents loads of oil being dumped into your intake and you're wondering why the cylinder heads are full of junk?

but everyone else without a catch can is getting oil dumped into intake

Yes because less that 3k miles of normal driving will cause this much carbon without a catch can.
