For me, the fouling problem at idle was the pressure regulator and damper. While in my 944, the regulator was safely under the hood, on the 325’s it’s under the car and mine was completely rusted.

On the early cars(my 87 iS had one) there is a fuel ‘item’ under the driver side rocker panel. I think it is called a Pulse Damper or something like that. I believe it is supposed to smooth out the fuel flow from the pump. On the street car I simply removed it.

Anyways when I happened upon the hot tub lets just say there was someone pretty big in it, and it looked like they were wearing a gorilla suit.

Al[/quote]That hot tub was the raffle prize…5 bux a ticket and the proceeds went to the Kimmel Cancer center. Hairy dude and one onher guy were the winners. Up until they got in, it was a fresh fill of water and no one got in. After though I have no idea…

These engines are so close to stock - mine is stock down to the airbox - that I’ll always use the stock plugs. BMW picked them for a reason.

Sean - didn’t the factory also specify the W8LPR as an option? That is what we have been running without any problems.

Ed[/quote]Bosch introduced platinums in North America in 1985… so it is possible…I just don’t know.

Looks like I got it backwards. That’s why my mechanic does the work and I do the typing most of the time.

Well, better late than never. My hosting provider (MediaMax) migrated services about 3 weeks ago and the services are finally working again. Here’s my video from Sunday’s race from the back (due to a brake line failure in the AM) leading up to the failure of the 2nd line.

The broken rocker that I fixed on Sat seemed to loose it’s gap setting on the valve as it was ticking really loud and (as you’ll see in the video) the engine seems down on power. I was making a run in 10 every lap and still, the car ahead would walk away.

Enjoy.

Yo E

Maybe you need to change the sig line to:

Brake Late Tempt Fate…especially if you buy your stainless brake lines online!

could not resist…

Thanks for sharing, cool video, I’d say you were significantly down on power watching that video :ohmy:
