How do you check for a jumped timming chain on this engine with no Dist.
A 5.7 has a distributor even in Vortec flavor, it just looks different in apperance and is a bit different in function. It is kinda hard to tell for sure without a degree wheel and a cam lobe spec. You can check for slop in it pretty easy though. Put a breaker bar on nut for dampner and attempt to rotate crank back and forth a bit as you will feel when it trys to "pick up" the cam. There should be less than 5 degrees on sloop as measured at crank (this would equal 10 degrees at cam since it turns at half speed) It there is 5 degrees or more it is time to think about changing the chain and if it is 10 or more you are starting to get up to where it can jump (10 degrees on crank would be
20 degrees on cam)----------------- TheSnoMan.com
Thanks for Info. Turns out was just flooded from not starting due to -25 temp. Cylinders were washed of oil.
