[urq] Burning huge amounts of oil after turbo rebuild and new EM after 6 months of use.

Now you mention it: the valve cover is also replaced with a powder coated 
piece... Perhaps it's the wrong kind? ETKA does show 2 types for the WR or 
GV: 035 103 469 H (F >> 85-B-900 158) and 035 103 469 S (F 85-B-900 159 >>) 
My chassisnr. is 85ZGA900888. Or perhaps it's from the KV: 035 103 469 R 
(btw. the automatic tranny KV's use the S type).

But how could that explain it only starts burning oil after 6 months? In 
that whole period it only burned 1 liter per 2940 km, just like it did 
before the turbo rebuild etc.

Will check that rubber T-split thingy on the back of the valve cover, 
perhaps it's clogged over time caused by the wrong type of valve cover? Will 
report later on.

To be continued...
