So, decided to replace fuel filters and a filter housing mount. I cleaned the housing with BRAKE CLEANER. (I know the rules about diesels and brake cleaner)

I thought everything was dry with no cleaner left anywhere. I was wrong. It was there somewhere. I started the car before I knew I was wrong. Oh the horror! I cannot emphasize this enough. I killed the ignition immediately and fortunately the engine died that instant.

I cleaned everything out and ran the car for a while. Everything "appears and sounds" fine. My remaining fear is that I may have made a hairline fracture on one of the pistons but only time will tell. I will add, idle is perfect after filters and linkage adjustment and I am happy with that.

That is my story and this is my warning, don't ever ever let brake fluid cleaner or anything combustable like it in your engine! Ever!
