Hello

 

almost 10 000 kms since the rebuild.  Have noticed a small oil leak, appears to be coming from this area around the clip, on the outside of course, what does it indicate, should I be worried, what action should I take,

thanks for your help as always

Leaking here is usually from the crankshaft seal, which requires removal of flywheel to replace. If it is very slight I would leave as is.

Did you replace the primary gear oil seal on the rebuild and what was the condition of the primary gear?

OK thanks, I thought so, the lovely orange seal, no it's just a tiny drop occasionally, but here in Japan at the car tax inspection they fail you for that kind of thing. I'll let it go for a bit and check some more that it's not coming from somewhere else and flowing near that area. Thanks for the pictures too :)

i have also a leak there and the area is perfect to clamp a small towel under the pin

just to keep your parking oil free. But someday id need to be fixed.

From my experience, if it is the Oil Seal, not all Oil Seals are equal.

 

I've had mostly good success with these;-

But, I believe these are better (though I haven't tried them);-

Check the bushes in the Primary Gear are not worn and also check that it's not oil weaping in via one of the bolts or studs.

 

<Edit: While not a likely cause, but best to check all the same, be sure the Crankcase breathers are not choked. >

Fitted the 1992 onwards seals to all our A+ engines(one is a 1989, 2 are 1993/4, all carb'd) all these engines have oil leaks, of varying degrees but a leak is a leak imo
