Anyone seen this much pressure bouncing before?

She wasn't completely starving cause I have 10 consecutive runs logged of it happening above 3400, and it's still running fine.. The analog gauge didn't show it [or I didn't catch it], but EFI tracked it on every run. She is spraying some oil out on the belt above 3400 from somewhere. I was going with front main seal on the leak but now wondering if maybe the bypass valve is bad.

Either way she's coming out for a bearing inspection. Is a good thing I've never ran it wide open for more than a few minutes at a time...:roflmao:
