I have a 1990 corvette....when I start the vehicle I get white smoke from
the exhaust..is this die to a bad head gasket..cracked head..etc...what
can I check to determine what the problem could be without spending
hundreds at a garage
Thanks in advance to all.......
overnight...probably minor valve guide seal leakage. Typical as L98s
age. (Some new L98s did the same.) When my L98 sat for over a week it
always threw white smoke. Now that it's being driven 3-4 times a week
there's less white smoke.) (58K miles on the engine since new.)
Don't know if the '90 used a PCV filter (the '89 did not.) If so,
replace it along with the PCV valve.
Otherwise: Rule out gasket -- Any oil in the coolant? Any coolant
After that, pull the plugs (number which cylinder each came from) and
visually check. If you don't know what you are seeing, have a trusted
mechanic look at them.
Take a critical look at oil consumption. If it's over a quart every 2K,
consider the type of driving and maybe see a mechanic.
