ok so this is what i have. Was wheeling today engine was running awesome. hit some high revs and it died. no pop no bang just shut down. have spark have fuel did a compression test and got weird readings. did test on cylinder 4 and 5 and four times each. readings were weird 60, 60,40,75. did a cylinder leak down test and everyting is holding. thought timing might be off checked it crank says its fine. I think the cam sliped a tooth or something weird like that. Anyone ever herd of this? or had this problem? another thing, i rebuilt this 4.0 about 6 months ago when i did the swap been running fine like i said it just quit. any help would be awesome be for i pull the motor again.
