Timing jumped (again)

Post by Redlined »

ok. duplicate sinario to 2 months ago, or whenever it was my timing jumped the first time (note i replaced the belt when I Did this the first time).

get off work 6am. Go out to a stone cold car. start engine. engine runs for maybe 2 heartbeats and dies(no sputter, no missfire. just turns off). Turns over but makes no effort to start.

Car ran PERFECT on the way to work. No sign of trouble at all.

Im assuming the timeing jumped. havent had a chance to tear into the car yet.

What would cause a car to jump time like that? My first though is one of my cams has a bind spot in its revolution somewhere that is magnified when the car is cold.

thanks in advance.
Dave

How is your tensioner? How was the resistance when you were compressing it? Is it possible you broke it when compressing it? You have to go reaaaallllly slow when compressing it or you will mess it up.

I would check that first. IMO

Tentioner seemed good. took quite a while to get it compressed(used a softjaw vice) tighten it a little, wait. tighten it a little more. wait some more. rinse. repeat.

Thats correct but take the cover off and see whats going on with your timing. If it jumped I would check the tensioner and your cams.

I'm sure someone else will chime in on this.

I'd replace the tensioner....especially if this is the second time this has happened....and everything else looks good.
