Have any of you replaced the valve guide seals with the motor still in
the car? If you have how big a job is it? My daughters car has two
hundred and fourteen thousand miles on it and its statred usuing about
a quart of oil every two thousand miles. It smokes if it set and
idles for awhile.
Generic response due to unidentified engine:
Place cylinder at compression TDC. Remove spark plug, apply compressed
air to hold valves on seat (or fill chamber with nylon rope, leaving tag
end to facilitate extraction, if working under a shadetree.). Remove
valve cover, rockers, keepers/retainer/spring.
Replace seal, reassemble. Umbrella-type easy, positive type no so much so.
Consume beer. Put next cyl on compression TDC, such and so forth.
Perhaps a leakdown test is in order before investing the time/money in
seal replacement on a tired motor with worn guides, rings, etc.

I believe you own a 94 Camaro (previous post) so have a look under
the hood - the valve covers need to come off... tell me how fun
that would be.
I like to coast down a hill in gear, and floor it. If you get a big cloud
of oil smoke, that goes away when you accelerate, that shows valve guide /
seals are poor. Coasting creates extra vacuum which draws oil past worn
