What happened?

Sorry to hear that Jerry

Congrats to Mosty, Proctor and Alford on the wins. Congrats to Proctor on the lap record!!

Sorry, maybe I spoke too soon. Any officials wanna check that lap record??

Best I can do is the 2010 points sheet from Round 6.
MSRH (2.38mi) CCW CMC 1:47.820 Jeff Wirtz 01/31/10
MSRH (2.38mi) CCW CMC-2 1:45.841 Jeremiah Kellam 01/31/10

Looks like CMC has a new track record.

Ha, good point!!

I plan on pulling my motor out this weekend and tear into it. For those that didn't know my "issues". Car ran really well on Saturday. No issues, no leaks. Good to go. Qualified on Saturday and reported to the dyno to figure out where I was for the year. Found the car had lost approx 12HP and 15TQ from ECR (don't know why).

I ballasted up and ran the "hot" tune at 325/335 and took to the track for R3. After about 4 laps I was getting smoke in the car at the top end of the RPM band (4500-6000). It happened on straight aways, so I was not thinking about oil slosh in the pan.

After R3 (came in early), I pulled the hood and had oil below the headers around the timing cover on the passenger side and also on the driver's side. The dipstick was slightly blown out (never happened before). I cleaned everything up and put a rag around the dipstick to hopefully contain any more oil that spewed out during R4. None of the oil was heavy enough to do anything but make a mess on the splitter at this point (and a bunch of smoke). There were no traces on the exhaust pipes or underside of the car. Also, the engine sounded like it dropped a cylinder as it was down on power at the end of the race.

R4 did the same thing, but the engine seemed to pull okay until mid-race and then more smoke and more engine noise.

I'm going to do a leak down test to see what is the issue, but it appears at this point that I'm pressurizing the bottom end of the motor and can think of:
1. Hole in piston
2. Cracked piston ring
3. Cracked piston ring land
4. ???
5. ???

Keeping my fingers crossed that it isn't anything horrible, but hey, it's only money and others lost a bunch more this weekend:

Dulaney = motor
Jordan = motor
Patterson = pinion
Mosty (older) = right side of his car
Francis = right side of his car (damned backwards driving...)

4. Blockage or routing problem in PCV system
5. Washed down cylinder walls / unseated rings (it's a stretch but possible)

I'm very curious to see what your plugs look like and what the leak down results are. It's possible you got a bunch of oil in the intake from a PCV issue that then got sucked into the cylinders, left deposits as it burned off, creating hotspots which caused some detonation and eventually cracked a ring land. It's pretty thin as theories go but I have heard of it happening. I would think your knock sensors would pull the timing down enough to save the motor though...were they hooked up and working?

Casey,
302 based Fords of my vintage don't have knock sensors, but I will be able to tell very fast is I sucked down oil... I have a seperator and it wasn't completely full after R3, but maybe it skimmed oil off the top and down into the motor.

I will pull plugs and do the leak down before I pull it out. Should know more by approx 2pm Saturday afternoon. (Finger's crossed)
