you may have wear in the cylinder walls and the rings may be worn out due to
improper oil changing or just wear from miles. Cold startups in winter below
20 degrees will affect wear because of no oil getting to the areas. Valve
seals tend to go bad, but the smoke dissapears after startup, just an
innitial cloud and puff, then its OK. The valve guide seals are the cause of
this. The only way to solve this is to use Engine Restore 4 cyl treatment if
its the rings, valve seals will not be affected. The CSL particles in the
restore fill the scratches in the cyl walls and restore compression. I used
this in my old 86 E16 and it worked and I got new power, it doesn't last
forever but it helped alot.
