Hi All,
Maybe able to offer some advice here.
I presume we are discussing a 3sfe or 5 sfe engine type?
unless you have cleaned down the engine and test driven it to enable
an accurate visual inspection,you are completley wasting your time. I
would suspect that the oil leak you describe will be the oil pump to
block seal ,this is a VERY common fault in both of these engines.It is
also nessasary at this stage of strip down to replace the front crank
seal and the oil pump shaft seal.
As you at this stage will have the timing belt removed ,it would be
lunacy not to also replace this.As in any timing belt replacement,
the idler and adjuster pulleys should ALWAYS be replaced.
Leaking sump(oil pan ) is very rare, however leaking rocker cover and
cam seal very common.This is a rubber gasket and a lot of people fail
to use a sealant ,using 3bond or similar is the only way......
Distributor o ring is common but on replacing this you will need to
reset the vehicles base timing, as the disributor must be removed.
In the very unlikley event the sump is leaking use a 1/4 drive soket
and rachet to first ensure all bolts are tight,BE VERY CAREFUL these
are untempered machine bolts and break very easily.We are constantly
removing same for "home mechanics".The sump gasket replacement if
required is not difficult in a well equiped workshop , and with good
trade skills but................
Hope this helps,
kind regards,

Thanks for providing such a thorough description, and appreciate the
suggestion about always changing the idlers.
Had been doing all these items already, but didn't realize the pump to
block seal leakage was common.

Hi,
I gave my car for AAA approved mechanic.
First they looked the signs of Valve cover leaking and replaced Valve cover
($180)..
Problem didn't go away.
Now they open the bottom part and changing the seals and gasket Dave
Strachan mentioned.
Seems they are learning this new things too because they are finding leaks
even after replacements.
Some how during timing belt, water pump change, mechanic didn't check/change
the seals/gaskets etc..
Roughly estimating another $500..
I am not sure whether its worth spending $700 for $3500 value car..
But going ahead and getting the work done..
