<div style="color:black;font: 10pt arial;">All I am saying is I find a lot of this hard to believe. For example: <span style="font-family: Arial; font-size: small; color: darkred;">Synthetic oil has much better cleaning properties, flows much better than conventional oil, and hence also lubricates much better than conventional oil. "</span><span style="font-family: Arial; font-size: small;">Much better" sounds good but is not very scientific. How much better, scientifically speaking? Just changing oil regularly does what you are taking about & none of it has to do with leaking unless you are counting on "sludge & gunk" to plug the leaking holes. Good Luck! Careful rebuilding including paying close attention to applying sealants where applicable, like bolt/screw threads when they are in contact with the oil will make a big difference. Re-tightening all the bolts after a break-in period will also assist. </span>

<div class="yiv0320298619MsoNormal"> </div>
<div class="yiv0320298619MsoNormal"><span style="FONT-SIZE:10pt;">All of
your observations are a factor. Here are some comments from an article about
synthetic oil leaks:</span></div>
<div class="yiv0320298619MsoNormal"> </div>
<div class="yiv0320298619MsoNormal">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).</div>
<div class="yiv0320298619MsoNormal"> </div>
<div class="yiv0320298619MsoNormal"><span style="FONT-SIZE:10pt;">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></div>

<div class="yiv0320298619MsoNormal"><span style="FONT-SIZE:10pt;">I am not
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></div>
