This Sunday I decided to run my 92lx wagon out the interstate at 85-90 mph to clear out a fuel injection stumble I had for a couple of weeks. I solved the idle stumble with Chevron Techron and the high speed run but now I have a smell of antifreeze out the exaust. I either cracked the head or popped the head gasket. First question: Does this generation of escort have a head cracking problem? Years back my 86 did the same thing and that took a head. The gasket on that engine looked fine. Second question:Is there anything I can dump in the radiator to buy me more time. If I cant put the repair off until warmer weather im afraid its going to the dealer. I was pulling 5 grand up a long hill, no more....Any advice is apreciated.
