Just Wanted To Know What Could Cause A Timing Chain To Slip. Or The Tensioner Not To Fully Pump Up All The Way?

Got Done Replaced Rod Bearings, Started It Up, It Ran Perfectly, Except For The Timing Chain Was Loose And Rubbing On The Cylinder Head. Got The New Tensioner Put In And Set The Timing Up Perfectly Per Manual Specs. Started Right Up, But Then The Chain Jumped And It Died. There Is No Damage, Due To The Chain Jumping And It Dying.

Do The 2.7 L Have A Timing Chain Issue?

Thx.

While you had it apart for the rod bearing did you replace the chain, water pump, tensioner and guides? If not then that is most of the problem. The other possible problem is low oil pressure. The tensioner is driven by oil pressure and if you had a sludge problem and did not clean it out you may be starving for oil in some parts which will also contribute to the problem.

didyou remember to release the tensioner before starting??the tensioner is locked down from the factory and after you install it it has to be unlocked,, then your safe to start it up,, to unlock,, just press the plunger back a bit and release.. that should take care of the problem :smilie_re
