I tested the glow plugs today with the ohm meter. Most of them read between 1.4- 1.6. I assumed that was high resistance since I've been told it should between .6-1.2. I removed the fuel injectors and got at the glow plugs easily. I'm waiting for my reamer I ordered from Phil which is supposed to arrive today to clean the chambers. Where can I get glowplugs for my 1979 300SD Turbo Diesel ASAP. Anybody have a list of parts places were I can get them quick online?
