did you silicon the front and the back of the intake or just leave it bare?? it might of finally on the last run it gapped the intake enough to creat a leak...and it just happend to be on the last run?? i'd check your heads and head gaskets first...
When I first put the intake on, I used cork. It wouldn't seal, kept leaking coolant into the oil.
So then I removed the cork and used RTV. That fixed it.
The last run... I went to a track on Friday, made some runs, then had a hard time starting the car Saturday morning - it wouldn't crank at all. Then I finally got it going, I had to crank the motor over by hand. Made some more runs Saturday. Afterwards I checked out what I could, the oil looked ok, the motor would start up without a problem. The next day I went to another track, again, I had a hard time starting the car. I should mention that this was in November, it was probably close to 40 degrees at night and the car was left either at the track or outside my hotel. Anyway, I had to crank the motor over by hand, but finally got it started. Made some more runs that day. The last run, the car just kind of eased out of the hole, didn't rev over about 3000 RPM for the first 60 feet or so, then it picked up. That last run was almost half a second slower than any other run that weekend. After that run (I lost, of course) I put the car up on the trailer, pulled the hood and started looking around. The oil looked like milk at that point.
I've pulled the passenger's side head off, the head gasket looks to be in good shape. You can see in the pics that outside the number 2 cylinder the gasket is wet. Also between 4 & 6. I'm not sure if that happened when I pulled the head off, though. The intake gasket looked to be in ok shape as well (no tears or anything).
One thing I noticed is that the water passage (look at the last pic, the top of the head gasket) looks like it's plugged up. I haven't gone back to look at the actual car to see what it is, though.
The heads look to be in good shape, no visible cracks or anything, but I know that you can't always tell by looking.
