Im at a loss, ridiculous blow-by please help

[TwIzTeD_3kGt]

Block still has beautiful honing marks. There are some straight lines but they were there before assembly, I cant catch them with my fingernail. I had the machine shop look at them and they decided a hone would suffice.

Donnie, the most knock I ever logged was 8 counts and that was once and on gasoline. After that I had none. Running a 10-10.5/1 afr on the gas scale with e85. Im not convinced it was detonation. If it was how do I tell for next time if I can't log it??
Ill get rings, bearings, and HGs and probably end up getting forged pistons in the stock size. I don't know I am uhhh not happy.

E85 detonation does not get picked up by our knock sensor. Someone correct me if I'm wrong, but torque output is how you determine whether or not you're knocking on E85. Advance timing until torque no longer increases, then back it off a bit for safety.

Next will be bent rods. You need lighter and stronger rods. If I may suggest Pauter Rods with the upgraded oil chamfer option. What manufacturer and style of bearing are you going with?

rings (which I checked with feeler gauges for appropriate gaps)

What I'm not reading here, is: "I ground the rings to an appropriate gap for a DR650 car at 28 psi that I'm going to overheat and try to stick the rings..."

I don't even know what you set them at, but if you didn't grind on them, they were too tight....

Where's Steve68 when you need him....

These blocks rarely crack (if ever). At the risk of sounding like banned member steve, "busted ringlands". As suggested already, do a leakdown test to see if it's valve or ring related. Also pressurize your coolant system to see if you breached the head gasket again.

I was channeling Steve68 in my earlier post

Okay I made a chart for the ring gaps but I cannot find the damn thing, they were all within the spec that was given to me by the ring company, well within spec, THAT is why I didn't grind them. They are stock pistons/rods/crank because well there was nothing wrong with them when I rebuilt I just wanted a fresh motor, and I was under the assumption that a stock bottom end is supposed to hold the power of dr650s, I talked with Ray about it before I purchased them. It would be nice, and safe, to have forged rods/pistons but it is not needed for this build.

I chose E85 because I wanted to be able to run high boost without running race gas, and I can get e85 very very cheap.

For the guy who asked what bearing company, I used clevite and will continue to use clevite.

I didn't know our knock sensors could not pick up knock from e85... Maybe the source was detonation in this case. It definitely fell off at high rpm, but I thought it was from running rich and crappy stock cams.

[KeithMac]

I've never seen genuine knock on e85 with our sensors either, I think if you get to that point it's already far too advanced!.

When I used it I didn't go mad with the timing and just enjoyed running more boost safely rather than hitting the ragged edge.
