theres was just tons of oil coming out the catch can thou. like i had a blue rag over the output of the catch can to stop the oil from getting on the manifold and i had to replace the rag 3 times cause it was filled with oil. its bad. not a single bit on the dyno... hmmm stationary vs g's on a road course.. or real life vs dynojet....

maybe it was just the missing i was experiencing at the track. part throttle. full throttle was fine. bkr6e thou, forgot to get some 7e's before the track day. aem log didn't show anything horrible, maybe knock sensor is dieing.

fail, fail, and more failure. stay away from me it might be contagious!!!

the only positive thing is if it is the head it wasn't my fault.

If you have bad valve guides it'll pressurize the crank case under boost, then suck oil in while off throttle. I'd think on a dyno you won't be tossing quite enough oil around the head to really get a huge amount in there. Or maybe the guides just seal worse when they get hot.

If it's detonating you should see some tiny specs of aluminum on the spark plugs from eroding the piston.

Took the head down today, Brian removed all the springs and we checked the seals. they look ok but not ok at the same time. I'll have to take a picture to show you what i mean. But I'm positive its the seals but Brian wasn't too sure. So I brought my old head with me just incase it would take long to fix or we didn't find a smoking gun. So i just had Brian put the springs on the old stock head and deck it. So it maybe running tomorrow. but smoking not 100% sure.

Its running again and NOT smoking. what a PITA. replaced pcv valve anyway and so far no crank case pressure. we'll see thou

Yay!

got the scanner out today. i know stupid mph bs. I'll try to get another one with RPM before i leave.
