When I first bought the "Pumpkin" (now owned by Pierre), I had a leak problem from all the injectors. I went to a junkyard and picked up an additional four from another 240D they had rotting. I lucked out and had access to a buddy's shop, and he had a "Pop Tester." I tested all 8 injectors, put them in order of measured pressure and grabbed the group of 4 closest to each other, and had my "balance." The dead injector we used to braise as an adaptor for the compression tester, leaving me a couple extras for "just in case." I snugged up all of the injectors on the vise grip, then installed them. No more leaks, no more unwanted sounds!!!! The car is still running around south Florida!!! If you have a place to test them (set up pop-tester), you may wish to do that yourself, to see if any are "dead." You can also pick up extras from a junkyard . . . usually cheaply, and put them into the group for testing and get your "balance." Keep one extra for braising as an adaptor for compression testing, and put the extras away for future need. When you take one apart, you will be amazed at how simply they are made. I had to replace the O-rings on all of mine (5 cent parts from O-Ring selection kit, then snugged them up on the vice grip. That car ran like a gas engine with all the power, and just the right gearing on the 4-spd. Only had to adjust one valve, that was off by a couple thousanths and she ran like a charm for the next three years with only oil changes!!!! Was the most reliable car in the winter in Montana, for the whole household!!!!
