Took my JY 6.0 apart to regap the rings, key crank, etc. When I checked the rings, the passenger side was all .024 and .028, first and second. The driver side was all .024-.028 and .032-.034, first and second. This is going to be a ysi boosted motor, but for now will be N/A. Are those ring gaps too much of should I just put them back in and let it eat?

How many miles it had on it?

Supposedly 56k on it. But after taking it apart, i seiously doubt that was true. Some of the rings were frozen in place, a cam bearing fell out of the block when I pulled the cam. But all of the bearings and cylinder walls look great. So idk.

I'm with RCR Drive it like you stole it. And turn up the boost until sumpin come loose

I had to open mine to .024 .026 mine were in the low 20s at 173000 mikes.

Yeah, that is what i expected to be doing. But i only had 1 top ring that was .022 and i opened it up. It is just weird that 1 side of the motor all had bigger ring gaps.

You might have some blow-by, but you won't have to worry about your ring ends butting together and trashing your motor.

Beat the hell out of it. It'll beg for more.

Stuck rings. Aren't you glad you took it apart?
My L33 were also crudded up pretty good. Esp the oil rings. All the ring grooves were full of crud.
The gaps though were .019" on the tops. I opened them to .023".
The 2nds were all .026" or so. I left them alone.

Without a doubt I am glad I took it apart. It wouldnt have lasted 5 minutes running. I am honestly real sour on the JY motor thing after this. No way I would install one without taking it apart first.

I wonder if a couple of 14-16psi pulls will clean all the slugs off

Heavy dose of water injection cleans up the motor pretty quickly. My pump gas 190k 3.8 Looked like this when I tore it down... KS 91 octane fuel and 24lbs of boost with water/meth. I was impressed! Wish I would have gotten a pic of the ring lands, they looked 10x better than anything I've ever pulled from an LS motor. Not sure what the graphite like material is...

Pic was taken immediately after I pulled head, zero clean up was done on either picture.
