I always use a small vacuum line to inject seafoam. last tiem I did it on the BMW (Jetronic K) I used the line from the fuel pressure regulator. Just stick the line in the can and it wil suck the stuffout like through a straw. You do have to rev it above idle to keep the engine running. I injected a whole can into the engine that way, let it sit about 15-20 minutes then started it up. You get lots of smoke and if youhave a lot of carbon a nice BBQ smell

I have never put in in the crankcase but you will have to change your oil immediately or you could damage the engine. I only run Mobil 1 and the engine is nice and clean after 24 years and 230K.

Another great product is GM Top Engine Cleaner, which you can get at any GM parts counter. I used it many times by pouring it down a carb throat. Same idea as with Seafoam, SLOWLY pour it in until you stall the engine, wait 15 minutes and run the engine. I just did it to my 34 year old Jeep and it made a HUGE difference. When I bought the thing it was running on only two cylinders and the other four were really fouled. The TEC cleaned them up (after I changed the spark plugs and wires and got them firing again)
