i will be brief, we live in ohio and it didn't get cool here at night untill about 3 weeks ago. my 01 cobra is garaged. i leave for work at 4:30, on one morning it was in the low 50's nothing special. i started the car and heard a rattling noise. i checked the oil it was full, and i thought i was mistaken. but when i turned at the stop sign and accelerated it started rattling again. i was only at 2300rpm. i shifted into second and the same thing. :fm: i called the selling dealer and they kept it a week and then called me and told me they had drained my synthetic oil and tossed my k&n oil filter. :mj: then they checked the oil pressure at the heads (90 cold 20 hot). the dealer called ford's hotline and they tell me they were told that it was "just" piston slap and it is normal. :cuss: i asked why it just started and they didn't know, so i asked "so...if this is normal was my car abnormal before?" asst service manager told me if it was up to him he'd drop in a new motor.(reman). so now..they put 10 miles on the car, tossed my synthetic oil and didn't bother to clean it (the car) and then say that my car is a-ok. bull crap. any help and/or opinion is welcome and appreciated. (so much for brief) thank you..oh yea mileage on car was 34950 when this started..
