I have found alot of useful info on this site over the years as i buy and sell cars on the side one of my joys is buying nice spi cars and swapping in zetecs from wrecked ones ,super easy swap! Now i have found an 04 SVT with 95k for my wife to drive back and forth to save on gas.When i bought it ,it had a lower end noise which turned out to be a very bad spun rod bearing ,i was planning on rebuilding until i ran across a great deal on a used engine with around the same mileage from a rollover.Got it installed now it wont crank.It is getting fuel and seems like its getting spark,i will check that in depth tomorrow,i was in a hurry.When i got the motor which had already been pulled the guy pointed out the sensor on top of the valve cover ,im guessing cam sensor,was broke ,no big deal i will just use my old one.My question is could this car have jumped a tooth or so when the other car flipped?The timing belt is on and tight,is there dots on the top gears to see if its in time without pulling the engine?Any and all help is greatly appreciated.
