Glow Plug Removal
I have heard horror stories about removing the glow plugs on diesel engines and in all my years of removing them I have never had a problem...till today!
This car is the E300D 1995 . I have had the manifold off for 4 days now tracking down and waiting for new Fuel lines and have sprayed the glow plugs every day a few times with penetrating fluid. The first four came out with absolutely no problem and while I was patting myself on the back for being so clever the 5th and 6th glow plugs seemed welded in place literally they didn't budge and after having worked on these things for many years I could 'feel' something was going to break and then there would be a huge problem.
I got out the torch and after two hours I was able to get the last two out.
I'm wondering if others here have had this problem and what they did to get them out?
heating them, spraying them, wrench back and forth, heat, spray, wrench etc... seemed like 50 times for each one. I used some asbestos for insulation and was fortunate to not burn any wiring.
I did cut the end off of the one hidden behind the oil canister to make it easier to get the socket on and off.
Now I'm going to braze a nut on the end of a numbered drill bit and make a 'ream' for the carbon build up. I can't wait to order one from Baum or Hazet.
