2.5L Engine Cam Timing and Crank Damper Issues. Help please


Recommended Posts

Hi everyone,

 

First off, thanks everyone for the pointers on my previous post regarding the cluster swap. Got pretty much everything ready to go on that one.

 

Today I was working on putting the engine back together and i was working on the timing cover and timing components. 

As I was putting things together I noticed two main issues. 

 

First: The camshaft bolt does not employ the trust pin used on the 6 cylinder engines. The Haynes Manual doesnt mention anything like this for the 4 cylinder. Is this correct? 4 Cyl did not get the hollow bolt with the trust pin on them?

I ask, because as you can see on my pictures, if I pull on the camshaft outwards, it can slide out about 0.300" away from the block. I am wondering if this would then hit the timing cover and cause problems?

 

Second: When I took the engine apart, I noticed how the previous owner had added a random small pulley as a bolt spacer to hold the crank damper in place. I decided to do a quick dry run and I pressed the crank damper in place using the proper install tools. I then noticed how when the nose of the crankshaft sits flush with the crankshaft damper at the front, there is a 0.303" gap at the back; in between the back of the vibration damper and the timing chain sprocket.

 

I have access to a lathe and I can make a spacer. But I want to know is this spacer should be made to take up the space between the back of the vibration damper and the timing sprocket, or should I push the vibration damper all the way in to touch the timing chain sprocket and just add the spacer up front behind the vibration damper crank bolt?

 

Any inputs on this will help me to know what to do next. 

Thanks anyone.

 

 

regards

Not an expert here by far, so do your own research. But:

When I switched out my harmonic balancer, there was no spacer in front of it. Also, the timing cover sits between the timing sprocket an the crank pulley/vibration damper/harmonic balancer, so you definitely wouldn't want to push the two right up against each other.
