squeal after oil pan gasket repair

1323 Views 4 Replies 4 Participants Last post by  bimmercary
Hello Folks,

I recently got my oil pan gasket replaced since it was leaking a lot. Ever since the repair was done, I am hearing squeal from the idler pulley/serpentine belt area. I had replaced the serpentine belt, idler and tensioner assembly a year ago. The repair shop says that the oil pan gasket has nothing to do with the squeal I am hearing now. Has anyone seen this and curious if there is a connection..since it is odd that I am hearing this back after the oil pan gasket repair job.

Thank you!

Maybe the shop got oil on the belt and now it's slipping.
Regarding the squeal, here's some brainstorming:

- if the mechanic took off the serpentine belt and put the belt back on in the opposite direction then...?

- the mechanic took the joy ride of their life in the car and it damaged the tensioner bearing, idler pulley bearing?

- the idler pulley bolt was never torqued to spec and its now making noise?
Use a water spray bottle method to test and possibly isolate the belt. That’s what I would do first. If it stops squeeling then replace the belt. If not then take it back to the shop and ask them to recheck their work before making accusations.

Thank you all for your valuable suggestions. I will try the water spray bottle idea and see if that helps and also check the idler pulley..
