2003 VW Passat 1.8 T Valve Cover Gasket Replacement Problem
I replaced my valve over gasket and then noticed that the two plastic covers over the
camshaft were not installed!! What do these things do. The engine actually runs OK, but
the idle is a little rough.
I believe those are oil shields designed to keep lubrication localized around the camshafts, not spattering all over inside the valve cover. Probably good idea to put those back on. Then, if the idle is still rough, you've got something else to hunt down.
