Thank you for those pics Diesel911.

I once removed nine....yes 9.....injectors from a 240D and a 300D. Both engines were running well and getting good gas mileage. I expected to find the Injectors would check out good on my Tester.

Guess what!!!! All nine had poor spray patterns and only two had pop pressures anywhere close to the mark. I WAS ABSOLUTELY APPALLED. That one piece of experience taught me more than any book could ever teach me.
