Time for a rebuild?

The accu sump will help a lot . I think the big issue is the oil that returns back to the pan . Over the winter I opened up some of my oil return holes and it helped a lot . another solution is to put it in neutral but I am not a big fan of doing this . I kind of wait until the chute is out and the car has settled down a little before I put it in neutral .

when we ran gas 406 we used Rotella t and didn't have any bearing problems then switched to alky we had to change bearings after every outting, a change to Brad Penn resolved the problem
we used a stockcar oil pan on at first and oil pressure dropped on braking then went to a Steff's dragster pan
I wouldn't recommend a fram filter to anybody

Thanks guys! Seems like i have a few issues to fix then. Oil accumulator seems to be a good thing, and also better oil. What grade oil to use?
What oilfilter do you recomend?
For those of you that use an oil heater - do you also heat oil between runs to get rid of the alky? I talked to a guy at one of the local races, and he used the same oil for the whole weekend as he heated the oil all the time to get rid of methanol.
Myself, i have changed all oil every 2 runs....but that is expensive.., and time consuming when there is tight racing.

I havent split the entire engine yet, but i have removed the heads, and a couple of the cylinders have been beaten. Not sure how bad i should categorize it, so i must ask my engine guy to check. I can feel the grooves with my fingernails.

I start my oil heater in the morning and use it all the time during the day exept during the race. I have built a tempersture controller to make sure the oil wouldnt burn.
I can see a big decreas of alky in the oil when heating so I suppose it i a good thing to do.

If you can get the Bradd Penn oil it is the best for alcohol . I have 2 weekends on mine and the oil looks perfect . After a race I will use the oil heater in my shop to burn off exess moisture I also use it at the track in the morning to bring my oil up to temp. While you have your motor apart take a good look at the way your oil returns to your pan this is just as important as a good pan . Also to high volume of an oil pump can make it even worse . If you are milking your oil that bad after 2 runs you might be way rich . One last thing is engine temp . alcohol likes heat!
