1) Of all the failures I have yet to see a Quad 4 ( Later Years the Twin Cam 2.4 )... Jump time...
2) When you start a Quad 4, the tensioner should do its job as oil is pumped throught the tensioner to push it out taking up the slack in the chain..
3) If it were to jump time, or when the water pump was replaced it the timming was not set right it will never run right.. Are we sure that the timming was set correctly? Did you set the timming or did someone else do it?
4) I have seen too many Quad 4( also Twin Cam 2.4'* ) Blow the head gasket as people did not want to pay to have the water pump replaced... That gets to be costly...
The Quad 4 is a good motor, I won't knock it as I have seen them go way over 200K, But even to get that far it did have the head gasket replaced along with the water pump.. I think the guys son sold it with 230k on it, and made several trips from Florida to Texas.. But when things go wrong with them it can get a bit expensive..
Blackbird you have any more info for us to look at?
