Default 94 Camry Oil Leak

My car is leaking oil. When I drive, and turn on my heating, i can
smell a little bit of burning oil (a little stronger smell when i'm
going slower, or am slowing down.) I usually takes about 15mins for the
smell to start, and doesn't happen all the time.

The oil leak is on the front right passenger side. From under the car
the oil comes over the oil pan, where the pan is attached, but I can't
tell if it is the oil pan gasket.

I took the car to a local mechanic, and was told 1) replace cam seal and
crank seal 2) replace rocker cover gasket and 3) replace oil pan gasket.
Seems to me like that's a little excesive, and they don't know exactly
what's wrong. Any idea on how i can find out what needs to be done? Any
way i can do the repairs myself? Any quick fixes. Thanks.

=========================

I have the 1994 four cylinder with 186,000 miles and it doesn't leak a
drop of oil, but I've changed all the seals recommended by your
mechanic plus some.

The seals and gaskets dry out over time with the repeated exposure to
heat they become brittle.

Your mechanic has mentioned the main ones to change - although the
"rocker arm cover" is now "valve cover" - no more rocker arms.

Every major service - 60,000 miles, (just did another at 180), I
change the valve cover gasket and grommets, distributor O ring,
camshaft oil seal, crankshaft oil seal, oil pump O ring and cover
gasket, plus all the fluid service and electrical service items. But
then I expect the car to be perfect. Just drove it 600 miles through
the desert, and then 160 miles through freeway traffic.

The oil pan seal change should last a long time. Use the Toyota "form
in place gasket" material aka FIPG, and follow the instructions about
squeaky clean surfaces and applying within ten minutes. You need to
remove the exhaust to gain access.

If you're working at home an air gun is very nice, also handy for the
axle nuts. The locking nuts (which are non reusable and need to be
replaced) really do lock on, at the upper flange and you can break
them loose manually as I have done, but takes a great deal of force.

If you need to do there repairs your self, write back for more detail.

There are name brand oils that are supposed to swell seals. I would se
if bolts are loose. There is flourescent dye that can be put in oil
and a special black light used to find a leak. Maybe its simply a
valve cover leak.

After further review it looks like the oil leak is coming from the oil
cooler located under the oil filter. The oil is then running down to
the oil pan and dripping off of the oil pan lip. What would be leaking
in the oil cooler (seals, o-rings, gaskets,...)? I just changed the oil
and filter last weekend. Perhaps I broke a seal or gasket when removing
the oil filter. Should I just replace the entire oil cooler. Anyone
ever replaced an oil cooler? Thanks for all the advice.

I have a 91 , dont know if its the same and its a 4cil, but an oil
cooler isnt on mine and I did not know factory offered. Are you sure
its not the filter, you could clean with laquer thinner and get some
JB weld or any 5 minute epoxy that is gas resistant if its a simple
leak. And at 20f it takes days to cure hard, forget the 5 minute cure
bs, but cold wont weaken cure just lengthen it. Are you in a hot area
that people use engine oil coolers, transmission coolers are more
common. So the mechanic would have charged and arm and a leg and it
would still be leaking. is a clamp loose.

The '94 four has an oil cooler. Ours developed a leak in the same
area. The dealer had just changed the oil, so they replaced an O-ring
for free, and that fixed it.

===========
Do not replace the oil cooler. There is a seal at the base that is
replaceable.
You need to remove the oil filter to gain access. Then you will see a
flange at an angle, secured by a bolt. Unbolt the flange to unscrew to
oil cooler and replace the seal. Fortunately, haven't had to do this
yet. You can find more detail here:
http://www.turboninjas.com/camry/
Not sure whether you need to remove the water lines. Probably yes.
Check the Factory Service Manual for further detail. I use it for all
work on the car. Have found a very few items that needed further help,
but generally it leads you right through, step by step. I always
replace the items they call out as non reusable to avoid future
problems.
When installing the oil filter, it is recommended to turn the filter
3/4 turn. I use a cap wrench that fits over the top and painted a line
on it with auto touch up paint to make it easier to see the 3/4 turn.
I like the Purolator Pure One oil filter. Solid construction, good
filtering media, nice base gasket. I used Toyota until they changed
the designation and part number to reflect manufacture in the far
East, filtering ability didn't seem as good to me after that.
