Injector Dilemma!
I removed my injectors (OM617 - '83 300TD) and had them professionally rebuilt/restored and I want to re-install them. Problem is, only 3 of the five old beveled discs that go in below the injectors came out. Two are still stuck in there. When I removed the injectors they had been way overtightened. Instead of the 90 newton meters torque the specs call for, I had to use a 20" breaker bar with a 24" piece of pipe to break them loose. What's that, 200nm? Who knows, but they were in there. And now I can't get two of the old discs out. I've tried flicking them with a screwdriver and all I've done is nick the center hole up - the discs themselves didn't budge. I left rag corners soaked in solvent stuffed down in there for the last few nights and I'm on my way to try one more time. Any suggestions? Would heat help?
Thank you in advance,

There's a bunch of threads and posts on this. Here's my soluiton. After some PB Blaster or something similer soaking for a while, I found that if you place a heavy rag or towel over the hole and crank the engine a few seconds, the compression should blast the heat shield out. The rag stops it from shooting out like a bullet. A lot of folks will chime in and say what a horrible method this is. BUT, it works and I cannot see how in the world this causes a problem. Make sure the hole is cleaned out because you dont want any junk going down the hole....

On those stubborn carbon packed heat shields, one trick that has always worked for me is to take a 1/4" dia flat face punch and a hammer, tap all around the outer diameter of the heat shield. This breaks up the carbon and the heat shield comes out easily with a magnet or a hook. No solvents needed.

I usually stick a 3/8" long extension down there and give it a kiss with a 3lb persuader.
