Subject: Let's polish the oil filter cap.
Stephen Lafredo purchased the oil cooler for his E36 M3 which came with a
new oil filter housing assembly. While he had the pieces off the car he hand
polished them and posted links of the result on Suzy's M3 digest. I agree
with Stephen that the stock ribbed cover looks really nice polished. I
assume BMW ribbed their cover for looks, strength or cooling. I purchased a
separate cover and bolt so that I could continue to drive the car while I was
having it polished.
Cover 11 42 1 711 075 $27.00 retail.
Bolt 11 42 1 711 567 $ 8.60 retail.
From the purchased cover, I removed the flashing from the circumference and
smoothed the rib faces with 150 grit paper. I was charged $35.00 to have it
professionally polished along with the bolt. I was told that to keep it
shiny I would have to seal it with some kind of acrylic. I have Eastwoods
Nyalic clear coat product which is ~ $12.00 per 12 ounce can. It is heat
resistant up to 600 degrees F. Suzy says that her polished wheels look good
without a clear coat. She cleans her wheels monthly. After three weeks my
unsealed oil filter cover looks like the day I picked it up. I may just
lightly polish it when I change the oil. Time will tell. I plan on having
the stock one from my car anodized to see what it looks like. I'm told that
anodizing it will result in a dull finish. Both Milos and UUC sell their (I
assume anodized) version for $135.00. The UUC one has the bolt torque value
(15-18 ft-lb) engraved on the cover. Ben said that he obtained this value
from a BMW mechanic. The BMW recommended torque value (from their technical
data information) for the bolt is 33 NM which equates to ~24.3 LB-ft. I'm
using BMW's recommended value. You decide who's value you want to use.
Thanks Stephen for the great idea.
