Re: [DML] Blue exhaust

[Horseman of PA <the_horseman_pa@xxxx>]

Question? what grade of fuel are you running? if your
running 93 it can be to rich for the engine, also if
the engin was primed and turned over alot without
addeding oil to the cylinders you could of damaged the
oil rings. Ussually a cold engine will blow white to
blue smoke that smells like oil when it is cold, this
is due to the oil rings allowing oil to get on the
side walls of the cyliners, as the engin heats up the
rings expand makeing an adaquite sel, the cat will
burn up any residue. not haveing a cat on there could
be whats produceing some of the problem but if it's
alot of smoke it is probally the rings. if so you need
to do a re-ring engine overhall, might thing about
doing the vales to while your in there. I've notice
though my Fiero which has fuel injection will puff
blue smoke if I go to high on the octane rateing.
older engines were desinged for less rich fuels. hope
this helps.
