Just wanted to share some imteresting facts that i found today. Im a Porsche wrench and have been for 20+ years. Today i had a customers boxster that was making noise and had cam timing issues. Car has been to several shops with no solution but thousands spent to try and fix it.

First thing i notice is an IMS fix from Pedros Garage. I gather data to get a baseline and then i disconnected the line and plugged it up, started the engine and the noise is gone and cam timing is back to normal. I have not done more testing but saw enough to know that i will never put one of these on any motor ever!!

Direct oil feed isn't it? Starving for oil or a crummy race?

amondc

Yes the direct oil feed one that pulls oil from the head. In my opinion that is the last place you want to pull oil from. The cams, lifters, etc need oil.

Sputter

It might work better with the deeper sump. More oil etc.

amondc

I think the fundimental flaw is where they are taking the oil from.

There's a good "food fight" on this subject over at the 986forum.
