When i start the car when its cold the passanger side of the engine has a ticking sound. When the car warms up it goes away. I just did a complete tune up and use Motorcraft 5w-20 engine oil and motorcraft 820s oil filter. What could this be?

 

Could be a belt thing.

 

i just replaced the belt and idler puller the beginning of january

 

Hmmm... Try popping the hood and you should be able to tell if it's internal or external. Also, does it increase w/ rpms?

 

theres a tsb out for this issue, i will look it up and post it in a bit.

edit, pm sent. material is copyright so i'm reluctant to post it.

 

try sum of that lucas oil treatment. that helped my friends probe, it would do the same thing
