Sorry I am a little late with updates.

2 runs Sunday at 90 degrees F and 6000' DA.

Run #1
Nozzles: 39
Pill: 90

Left on the foot brake so ET was not great. 8.43

Sprayed oil out of vacuum pump breather again.
Changed oil after run. Very milky. Far worse than with the 41 nozzles and 88 pill.

Run #2
Nozzles: 39
Pill: 95

Car ran 8.20

Sprayed oil out of vacuum pump breather again.

Drained breather - oil was still very milky. I had to cut the top off of a water bottle to drain the breather. The knife was very sharp. I did contemplate cutting my wrists! LOL

One more race weekend coming up Sept 2 - 4.
I am thinking of putting on a crab and switching to gas for that weekend and see if there are any issues with oil spray.

I don't know how much leaner I should go on the methanol.
I would go no leaner, there has to be air sucking or a restriction, did you have your data logger hooked up ?
I had it hooked up but I haven't had a chance to view the data yet. Damn work gets in the way. I don't monitor the crankcase pressure with the data logger though. Just RPM, DS RPM, fuel pressure, G forces and voltage.
The dash fuel pressure gauge during the run went to 70 psi, which I think should be ok.
I can't help but think there is an internal problem with this engine. Valve timing, head gasket, intake gasket, cylinder wall damage, piston or ring damage. It is building way too much crankcase pressure.
You OBVIOUSLY have a Leak~Down Tester,.........?USE it,On the MOTOR!!!!!
