today was a great day for my camaro. My dad and i installed the doors, trunk deck, and inner fenders on the rolling shell. slowly we have been doing as much as possible with out the sheet metal in the way. Any way, the car is mechanically sound so we decided to test out the clutch adjustment and see how she ran rowing through the gears. We jacked up the rear and placed it on jack stands and let her rip. It was great rowing through the gears and down shifting until the balancer started to sling oil all over the place. Turned off the car and noticed a small puddle under the motor. great, im thinking it is the oil filter (had issues with the pan gasket) turned out that is was the timing cover seal behind the balancer. I grabbed a screwdriver and nudged it back in to place. I did get to drive the car though, in reverse right back in to the garage. Looks like i have to tear down the front of the enginewhat could have caused this seal to pop out? we have ran this motor quite a bit letting it idle and revving it up every now and then, but this is the first time we ever put serious power to it, my uncle said the car jumped quite a bit when the secondaries opened up, guess its not a smart thing to do on jack standsIm running a pcv valve and an oil plug in my valve covers. should I use a breather instead of the oil fill plug? my dad was thinking we have too much crank case pressure.
