if im not mistaken, most early model valve covers are not metal, only model year 1993 are. tasts why they look so bad after sand blasting.
They are definitely metal, but they are magnesium. The 1993 ones are steel. IIRC.
Yes...this is true.
Those magnesium ones can get pretty nasty if the corrosion sets in.
I likes the black!
Did you pull apart the tensioner before you coated?
