my 2056 Type IV leaks a couple of 3-4" oil spots every time I drive it, which is a couple days a week lately. the drain plug has a new copper washer, and the taco plate has new rubber and paper gaskets with gasket sealant.
I think the leak is from the case halves. Mobil1 10W-30. Would a higher weight oil make a difference? Man, I hate oil leaks! |

not to be argumentative but I have never dropped an engine from a 914 that was not covered in oily crud, especially under the cylinder cooling tins. the base gaskets scrub from use and they leak, two different metals and expansion rates, oil gets by. pushrod tube seals and oil cooler seals are notorious for leaking over time. curt, I think your recollection of your 63 bsa is clouded. they leak from the rocker shafts, the poorly designed plain bush on drive side of crank and the shitty felt gasket on the trans mainshaft. my 51 goldstar is as oil tight as can be and it pisses oil when ridden more than around the block. they all leak at the cylinder block/ case surface. least I have ever seen is my bmw r75, but it still weeps when ridden at the cylinders.
