Default Smokin 93 Camry 3VFZE

My girldfriends 93 Camry LE Station Wagon is 'lightly smokin' from
under the hood (not exhaust). (3VFZE V6 140K) Immediately it was
obvious both Valve covers where leaking and she also needed her right
CV Joint replaced. So to get to the point, I cleaned the engine
compartment with some degreaser and carefull use of a pressure washer,
replaced the right CV Joint and Replaced the valve cover gaskets, (the
rear valve cover gasket was a complete pain in the ass, a little slack
in the rear wiring harness would have helped alot)
Results:
Both valve covers appear to be sealed fine (very hard to see rear cover
but looks ok.) I am still seeing a small amount of smoke from underhood
within 15 seconds or so after engine is started (Comes up lightly from
front side of motor first and then heavier from back side), right side
of motor was very oily (her right inner and outer cv covers where
ripped so at first I thought it was grease and dirt everywhere) I am
guessing oil pump seal may be shot also. I would think that I should
see oil dripping onto ground if its leaking bad enough to cause smoke
by dripping onto exhaust. But only a very little amount of oil dripping
to ground and it smokes to soon to be dripping oil burning on hot
exhuast, at least I think so.

I dont have a lift so seeing underneath is difficult with only ramps.

Anyone have any thoughts on what else to look for or check that would
cause smoke to emit from engine compartment (smells like burning oil or
power steering fluid)?

Anyone out there have a simlar problem with there V6 Camry? Would a
clogged catalytic converter cause same problem?

ANy suggestions would be appreciated.
THanks

Agree that you have a fairly bad oil-leak onto the exhaust,..most likely the
rear manifold or its engine pipe. Trouble with oil-leaks is, they can run a
fair distance along a ridge on the engine before finally dropping to the
ground (or onto the exhaust).

Sometimes built up grease can take a long while to burn-off, or things like
a plastic bag caught on the exhaust can burn-generate smoke for quite a
while, although the smell is very different to oil burning.

You need to get the car up high enough to be able to visually inspect while
the smoke is there. Ramps, if they are high enough and don't foul on the
suspension, are a good idea for this.
