I too have had difficulty making a leak free engine on my street/race TR3. =
I also had an oil drop on almost every pan bolt head. I resealed the pan =
a couple times finding that the sealant had almost no adhesion to the alumi=
num filler block in front. So I thought that where the leak was coming fro=
m. I think I tried both the gray and black Permatex. After pulling the en=
gine for a refresh, I found that the oil leak was most likely coming from b=
etween the engine mount plate and the block. I had used the red spray-on H=
igh Tack sealant on that gasket. The gasket peeled cleanly off the block a=
nd plate and was saturated with oil. Oil never dripped from the pan or eng=
ine. It was pushed back while in motion and always dripped off the trans b=
ell housing. I developed an easy to change, disposable shop towel hanger o=
ut of safety wire between the two lowest bell housing flywheel cover bolts =
and never had a drop of oil on the garage floor. I changed the towel befor=
e a race weekend. =20
One think I was happy to find, was that the rear main seal was definitely n=
ot leaking. =20
If I find a photo of the oil diaper arrangement, I'll share it.
