No Compression

Have a 1994 Ranger XL, 2.3L engine, many, many miles. From the beginning: My Ranger has almost always ran really good up until 4 months ago, always started at the first turn of the key, regular tune-ups, oil changes, etc. Then all of a sudden the timing belt broke (one reason is old belt - I had just replaced the serpentine belt and was working on getting others done). From what I can gather this Ranger has a non-interference engine so when the belt broke it shouldn't have bent any valves. I had my mechanic put on new timing belt, but the truck gets NO compression upon attemps to start it. ??? My mechanic is a good one, but not used to working on Fords. Help, I am hitching rides.

Sounds like belt is on wrong. I have replaced dozens of these and have never had one bend a valve.

I agree, not timed right.

I have a 94 but don't remember for sure but I did a 98 (2.5) a couple weeks back and it has several marks, only some work right.

Its probably a couple of teeth off and the intake valves are probably still open when the compression stroke starts. Each tooth equals about 18 degrees of crankshaft rotation.

I think it is pretty common knowledge that the camshaft sprocket timing pointer on 2.3L engines is woefully inaccurate. A neat trick to set the cam timing is to take a piece of string and run it between the center of the auxillary shaft and camshaft bolts. Scribe a mark or fabircate a new pointer that lines up with the string and then set the cam timing to that mark or pointer.

I probably should do this soon - Is it possible to just mark the position of each sprocket before removing, then match them up when re-installing? Or is there more to it then that?
