2005 Jetta 2.5 with lots of white smoke in exhaust after valve cover replacement
My family has a 2005 Jetta 2.5 with 142,000 miles on it. We just had the
valve cover and one ignition coil replaced due to an oil leak that caused
misfiring in cylinder 1. Since this repair, we have seen large amounts of white
smoke billowing out of the exhaust that is coupled with a lot of valve clatter.
Once the valves stop clattering the smoke goes away. We took it back to the
shop that did the repair and they said it is an internal issue and would cost
$800 just for diagnosis. We also did a compression test that came back good
on all cylinders. Does anyone have any thoughts on what is causing the
smoke and why it would show up after a valve cover replacement? I'm happy
to provide more specific information if needed.
