Changed vanos seals and valve cover gasket
Done at Optimum last Saturday. Met a fellow E39'er Faris (?) with a red 1997 528i converted to 540i M-sport! Forgot to take pictures of his car though.
So here's the vanos replacement:
Before starting, letting the engine cool off a while
Valve cover opened, looks quite aligned to the naked eye (to me anyway)
Now I know its off by about a third of the block
Realigned, now get to the Vanos
Everything disassembled and cleaned
Dried
Old Vanos seals cut off. It was really hard and brittle compared to the new Vanos seals.
Vanos piston without the Vanos seals
New Beisan Vanos seals
New Vanos seals on the piston
Aligning the chain using special tools
Brace for re-tightening the screws and bolts
Vanos goes back on, and then reassembling the valve cover.
All done, RM250 labour for the Vanos seals replacement.
Did an oil change too and other small things.
