Why woukd you suspect that?

[68_GT]

Engine light came on. Had it scanned its code P0016 cam/crankshaft position sensor. My guess is timing chain stretch ??! The car normally runs strong even at 95k miles but occasionally it feels a little down on power and I had heard other EB were pulling timing due to the chain stretch.

For the F150s, but should be applicable to the SHO.

 I just want to know if I can buy the parts and fix it myself or have another shop fix it. I believe I read somewhere the dealership charges $2700 for this repair.

Engine light went off and my SHO seems to run great. Do these timing chains ever break causing a catastrophic engine failure?

I just switched to Aimsoil and replaced the store brand filter to a motor craft one and most of my start up rattle has gone away

Thats certainly some great news to hear,so you went with the 5w-20 oil and M.C Filter correct? What did you always use prior? Z   

[salsathe4th]

Yes 5w-20. I just got the car at the end of summer last year so the only other oil change I had was from a place that put in federated oil and a federated auto filter. My belt has always been loud when starting the car.

Over time, the Amsoil should also help clean up things inside the engine somewhat; the hope is it will nearly eliminate the rattle.

[68_GT]

Are you thinking it will eliminate the rattle by cleaning oiling holes in the chain tensioner ?

Any and all oil passages, including those, correct.  Though I should make it clear that the Amsoil Signature is truly their best offering.

[68_GT]

where do you purchase Amsoil oil ?

Direct

Sign up for the 6 month nembership, wait for the materials to arrive, then go online and buy.  You can also look up distributors close to you on their website, if you want to skip all that.  Probably no discounts that way tho.
