Oil Smoke from exhaust

Do a compression check, with and without oil, to determine if it is valves
or rings.  Likely intake valve stem seals also.  700/qt is not good.  My
20Vs, original, get 7K to 10K/qt at 160K and 195K, respectively.

Find the source of the PS leak.  Most probably one of the cylinder head
O-rings, a cheap fix.
