Default What are the sources of Engine oil leak

Hi,

I am seeing Engine oil leaks from my 1994 Camry LE 4cyl, 4dr.

Yesterday I checked around Drain plug and no wet/oil around it.. and not
from Oil filter (FRAM fiter).

I am seeing drops spread around the Oil Pan and close to Axle.

1. Does Oil pan have Gasket or possible to leak ??

2. Any cracks on tubes/lines carrying Engine oil around the Engine ??

Appreciate inputs on how to diagnosize the leak ??

Thanks,
Rama

The oil pan does not have a gasket, no. Toyota uses something called FIPG
(form in place gasket), which is a black sealant spread around the edge of
the pan before installation. It may very well be leaking considering the
age of the vehicle, but the oil that you see may also be from the oil
filter. When the oil filter is changed on your car, oil runs down the
front of the block and over time invariably weeps around the seam between
the bottom of the block and the pan. In other words, residual oil from
normal service collects around the top of the pan and can look like it is
leaking.
Go to the parts store and grab a can or two of brake cleaner and spray
off all the oil. The brake cleaner will wash off the oil and leave
everything dry. Check the area again before your next oil change. Hope
this helps.

Yes. It depends on how careful the kid changing your oil is. But
beware -- if you go to your dealer after a sloppy oil change the dealer
will want to sell you lots of work to cure the "leak". Some crooked
dealers and tranmission places actually have a squeeze bottle of oil
that then can use to rig a car with.

BTW: the transmission can leak too! I had to replace the seals of the AT on
my '92 at 300,000kms...

Besides careless tech doing oil changes. How high do you see the leaks
come from? Sure, the oil pan gasket (form-in-place) may be due for a
re-seal.

Also cam shaft seal, oil pump seal and crank seal. You have to take the
timing cover off to check these. These leak behind covers and show up
near the bottom. Rear main seal if you see oil between the engine and
the transmission.

Valve cover gasket, particularly on the back side against the firewall
leaks will be harder to see there.
