I knew I had problems at the taco plate because it was really leaking there. Lots of grime and oil. I suspected a bad o ring, missing bolt crush washer or some one left the paper gasket off. Started to clean off the area when I found lots of RTV under the dirt. I started peeling back the layers and found 1/4 of the case ring was missing. (IMG:style_emoticons/default/WTF.gif) No damage anywhere to the rest of the case or the motor bar. I am lost as to how this got damaged. The only thing that comes to mind is a floor jack. I guess I will be looking for a new case and doing an overhaul. I just love DAPO's.

I've fixed that before - in my shop.
Not in service, only with the case disassembled, although it would be "possible" without doing a teardown. A good welder can build up the aluminum so the seal bore can be recut in a Bridgeport. |

Wait overnight until all the oil is drained, put the strainer back on with the O-ring and then dab the area with Hondabond(google it). It will seal the area just fine. I had a case where the drain bolt was over tightened and the through bolt was stripped. I put the bolt back through with hondabond and tightened the drain plug and this was 10 years ago. Not one drop of oil on the ground since the repair. JB weld sucks!

Not one drop of oil on the ground since the repair. JB weld sucks! Same principle. I use Yamabond 4 I think. I sealed an active pressure fed oil leak on my 928 engine between the block without pulling the head. Clean, clean, clean, reinstall the cover, apply the Yamabond, let it set over night. Save you from pulling the engine and splitting the case, welding and machining. |
