That looks like a lot of oil in there for only 1000 miles... what plugs TR6 ? Head cooling mod done ?
How long do you think this will last?

So it had a 2.76 upper and 2lb lower previously? And those were swapped to factory sized pullies? Caged lower? Were you seeing 8psi on a boost gauge to verify?
yessir TR6 plugs gapped to .36, head cooling mod is done as well.
yessir factory size pullies upper & lower, did verify 8 psi with stock boost gauge would peg under 10 lbs.
you may be right, shitty part is i have a state ref appointment march 1st to get this ****er into my name finally since its been down with engine issues since i bought it. With it all back to stock i thought it was good to go but apparently not, if it was due to fuel or leaning wouldnt the plug strip go first?
I just feel maybe the cylinder wasnt cleaned up enough? you can see lines and what looks like specks in the cylinder wall in the pictures above.
Any pics of the other cylinders ?
no i can take some tomorrow but i will say they look normal, smooth, normal light carbon on thr piston heads.
heard all too familiar ticking
Did you pull the valve cover off? It honestly looks like little pieces of metal were banging around the top of that cylinder. I thought all the pistons looked like that, that would be more indicative of bad gas.
have not yet, but im thinking something dropped into that cylinder idk, also could possibly be part of a piston ring maybe they didint clean up the cylinder correctly or check clearances idk.
Maybe that little chunk of whatever on the right is what’s doing it.
I thought maybe that was melted piston but maybe not. Usually it would melt down.
150-142 isn’t far off.
See if you can get that piece of whatever out of there

exactly what ive been trying to figure how to! i cant use a magnet tried already its aluminum. or its pressed onto the piston head already, also the 150 across & cylinder 8 @ 142 is all with the motor warm,
yup sucks, im tired of waiting and relying on people and shops that end up doing shitty jobs, L&R engines in Santa Fe Ca. im going to build the motor myself what else do i got to lose. i just hope i can get by this damn state ref inspection march 1st pass and pull the motor.
Best built motor won't stand up to a bad tune and/or fuel.
trust me i know! ive experienced that first hand, but i truly believe this situation is different.
I would compare that plug to some of the others. It looks like a piece of the ground strap is missing; the tip appears to be jagged and short. Also, the piece of metal on top of the piston in the other photo looks like it could be the piece that's missing.
