67 TC250/T20 Can this be right??

Ok, got it running yesterday so took out the motor to begin cleaning and fixing her. I have noticed that there have been small puddles of 2 stroke oil after I run it. Not anywhere near the oil pump but in the middle. I thought perhaps the center crank drain plug was the culprit but it's not. When I flipped the engine upside down, I can count only 2 bolts on the bottom to hold it together. Indented near the suspected drain plug there are 2 holes, one a bit smaller than the other. Oil is coming out of one of those. I count a total of NINE....NINE holes in the bottom that either don't have bolts or never should have. My book doesn't show it very good. Can this be right???

Doug can you supply a pic of the areas of concern

Most strokers have at least one, and lotsa times 2 or 3, drain holes running from the top of the engine casings clear through to the bottom. If you have injector oil leaking on the floor through such a hole, you better check for leaks at the banjo connection points at the engine AND the pump. You may also have cracked lines, especially where the banjo fittings are molded into the lines at either the engine end or the pump end.

I'm a little confused, and maybe a picture would help. I know my GT250 has umpteen bolts going from bottom to top to hold the whole thing together. If what I hear you saying is that there are only two bolts holding the upper case to the lower case, you're missing a whole bucket of bolts!

If this was true, they would almost all certainly bleed oil because there wouldn't be sufficient clamping to hold the case halves together and either the gearbox oil or anything in the crankcase would certainly wick between the case halves and come out.

KR: There are umpteen bolts going from top to bottom but only 2 from bottom to top?? Wifey is gone with the camera til thursday. I'm not very handy at posting pics but when she gets back I should be able to at least do the attachment thingy. Thanks

Rick: Quite a bit of leakage on the pump but not so much that it drips on the floor hardly at all.

Thanks Rick. Looks a whole lot better in the pics than up close. LOTS of work to do on it! That's the fun part though, Having a bike 42 years old and making it look "almost" new.

For anyone who hasn't seen them, crankcase pics are posted in the repair forum under "rotor removal?. Doug
