I just read in MMFFs magazine that the early terminators had a hot spot in the rear of the drivers side head that could cause an exhaust valve near the area to overheat and start ticking. I have a relatively early build number 2003terminator that I bought used. It is totally stock, and I am sure it hasn't had a cooling head fix kit or anything. It also has a loud tick at idle. The car runs great and has plenty of oil pressure. It smokes a little at start up, but I am assuming that is from the PCV system. If the exhaust valve is damaged and causing the ticking noise, should I not drive the car? Has anybody else had this trouble? Who makes the best head cooling fix kit or should I just get the improved head from Ford? I have another issue too. I think the clutch may be worn out. It engages really close to the floor, and the tranny is kind of hard to shift unless you really press the clutch hard into the floor. The clutch doesn't seem to be slipping though. Any thoughts? Would an adjustable clutch quadrant help? Thanks for any help or info.
