Hello my name is ***** ***** I can help.

There has been a problem with the camshaft cover. The pcv system goes through it. The valve on top starts to go bad and sucks vacuum.

The cover needs to be replaced. This part has a 5yr 100,000 mile warranty.

You could post your VIN# ***** miles I could check for you

If this helps let me know
