Replacing timing chain assembly

Hello, i been gone for quite a while. Since last post I've moved to Arizona from Ohio and the old 88 PA made the trip perfectly. I still have the service engine light due to code 41, I tried the glue in cam sensor idea but still have light so I assume it flew out from centrifugal force at start up.

The old gal has 160K with original timing chain. I'm gonna change out the TC assem. as well as the cam sensor, crank pos.sensor, gasket. Anything else I should change while there? Any special instructions or pretty much straight forward process?

BTW, AC pump went out during 120 degree Arizona heat and cost me 900 bucks to have replaced.

This is a great old car and I hope to run her for a long time.

Regards, Don

I believe there is a cam thrust button and spring also that should be changed, check into that also.

The U-Pull -it wrecking yards are full of these in Phoenix. You can bank some parts pretty cheap.

The parts store says there's no way of knowing until I tear into it. Do I need to pull the water pump?
