Does synthetic oil leak more?<BR></FONT><BR></DIV>
<DIV></DIV>Bob-that was another place the synthetic comes out...thru the
threads. If you use anything, like pipe sealer or PTFE (teflon) just be careful
not to get any near the entrance to your overdrive. Overdrive oil must be
spotless due to the tiny drillings in the system. I was able to fix my seeps
elsewhere with Permatex "Right Stuff" but be careful again to do a very neat
job. I still recommend regular 30W non detergent mineral oil (as does the
factory book) to refill the trans and OD. Some modern oils can foam in the
overdrive and cause issues.
<DIV><BR></DIV>
<DIV>Even though the factory manual states not to use sealant around the casing
seal of the brake ring-that will leak with most synthetics and also seep with
regular oil. Had to" Right stuff" the casing seam post rebuild to stop that
seeping. Another place synthetic runs out is at the bottom casing plug. I do not
have too much experience using silicone gaskets. I rebuilt with paper and
aircraft sealer (old school-but original). I expected leaks or else it
wouldn't be authentic British. Hank<BR><BR>

problem is leaking from the brass drain fitting in the bottom of the
overdrive. When I used motor oil eventually by tightening the fitting, the
drips would stop. With the synthetic oil the drips will not
stop. Over the summer, while the car was sitting in the garage, there was
a puddle in the plastic container I placed under the fitting before leaving for
cooler weather. I just tightened the fitting a little more and the drips
are reduced to 2 per day. Am thinking about using a thread sealant on the
fitting and RTV on the gaskets. Or, is there a silicone gasket
available?</SPAN></P>

your observations are a factor. Here are some comments from an article
about synthetic oil leaks:</SPAN></P>
<P class=MsoNormal> </P>
<P class=MsoNormal>Synthetic oil WILL NOT cause leaks. It may however make
already worn-out gaskets/seals more evident, by leaking past them, and/or
cleaning any sludge and other gunk that was sealing the existing leak. This is
because Synthetic oil has much better cleaning properties, flows much better
than conventional oil, and hence also lubricates much better than conventional
oil (This is a good thing).</P>

<P class=MsoNormal><SPAN
style='FONT-SIZE: 10pt; FONT-FAMILY: "Arial",sans-serif; COLOR: blue'>I use a
GL-4 synthetic gear oil in my transmission and it leaks. Believe it not not one
of the leak mechanisms is from the interior along the bolts and drips from the
bolt head on the exterior. I am changing the gaskets on my transmission and
trying bonded sealing neoprene washers on the fasteners.</SPAN></P>

a leak expert, but I find this hard to understand. For there to be a leak there
has to be a hole. Is it because the synthetic oil molecules are smaller than the
non-synthetic oil molecules? Given that the "holes" come in different sizes this
seems illogical. Is it because the synthetic oil is more slippery? How is that
measured? How much more slippery is it? </SPAN></P>
