My th 400 is pucking some oil at the end of the 1/4 shouls i install an overflow can or should i go down on the oil level ?
It's rare but I had it happen once. I had a 400 that did the same thing, it was probably due to a internal leak in the pump, possibly being warp. It would cover the fire wall and fill the puke can. What I ended up doing to cure it without pulling the trans was plug the vent on the case, then putting the vent on the tailshaft housing at the very top and vented it to the puck can, problem solved. Remember, this is no big deal, some Ford C-4s have this set up also. BurtOn the video it shows smoke on the power at the end of the track after a coupls of passes there was less smoke the level was slowly going down
i was running it at the full mark trans hot in park
