[TR] TR3 Oil Pan Leakage

      I have been trying to get the oil pan to quit being so leaky for 
over 30 years and two engine rebuilds now. I made sure that the bolt 
holes in the pan are lower than the mounting surface. I check the pan 
fit with a feeler gauge with no gasket. I get everything cleaned off. I 
have tried Permatex, Aviation Permatex and Hylomar Blue. I have used the 
recommended torques. Still slowly seeping and dripping over time. It 
seems worse in the front that the rear and no the front aluminum sealing 
block isn't stripped out.

      I have family members asking me not to bring the TR3 and Morgan 
over to their houses because of the amount of drips.

      I have looking over the "Triumph Experience" website and it looks 
like most owners there have thrown their hands up and given up. Either 
that or the ones that say that they are drip free probably haven't 
driven their cars much.

      I've considered CNC'ing a 3/8" steel mounting flange, welding that 
to the top of the oil sump (the weld would seal on the inside) and then 
torquing that sonofabitch down tight with permatex on it. No more 
worrying about flange distortion.

      I've also considered making a sheet metal "catch box" that would 
mount under the pan and completely enclose it to catch drips. It could 
be held on with 4 bolts and removed/cleaned out at oil changes. I should 
make a long aluminum drip pan that goes under the sump, rear seal and 
transmission.

      Anyone ever get there TR2/3/4 oil pans to stay drip free?
