Reset the ECU after you do the fix. Pull the negative battery terminal for a few. This will allow the ECU to relearn its fueling, etc. give it some slow steady driving with little to no boost for several miles. After a few cold starts, she should be good to go and repopulated with the new parameters.
Since were talking about that hose, whats the name of that entire line? With the metal piping that connects from the left side to the right side and is attached to the tmic?
Cylinder Head Vent breather line. Mouthful, but accurate.
The tear in that hose may cause a fairly substantial vacuum leak. In CL fueling, the car will correct for the disparity in fueling. However, in OL, the vac leak may be gross enough to put the IAM below 0.5 and the ECU will pull timing and boost.
Yep. Blowby exits through the PCV and the cylinder head vents. As you know, the EJ motors (particularly the EJ25x variants) are known for excessive blowby.
I was recently working on a friend's EJ255, and the car was just pissing oil out of the cylinder head vents. yikes.
