annoying little oil leak - xflow
HI All,
I'm back on the road, with a new engine, that wierdly has an annoying little oil leak.
I previously had a 1300, that had a minor leak from what i thinkkwas the crank nose seal. only a few drops a day nothing that would cause a failure i
put it down to being an old engine
I rebuilt a 1600 over xmas and fitted it, and it appears to have the same problem.?
Is this a common thing on xflows? or is it easy to make a mistake on the assembly?
Again it's only sort of 5-10 drops, and onl y when at temp. so i can easily top it up once a week. It's just annoying that it's
dropping oil and making things dirty.
Any comments welcome
Many thanks

no vac pipe = pressure build up inside case = oil leak... 
crank case vac will suck and seal oil in wen runnin
if leak when off = poss oil level above crank seal.....

there is no reason why it sould leak unless either the seal is or crank pulley is worn.
to fix it you would need to replace the seal (or pulley) - I need to fit one but to remove, use a large screwdriver in between seal and the timing
cover and twist to lever the seal out.
you need to examine the crasnk pulley surface. if this is grooved, then it will leak and/or wear a new seal out quickly.
if that is the case and you cannot get a replacement pulley, then you would fit the seal so that is is not in all the way; this ensures the lip of the
seal will run on a new section of the pulley that is hopefully unworn.

ok interesting points.
It was a new seal and a new pulley (burton solid type)
I don't have a vac pipe, but the case is vented toa catch tank.
I think the oil level is correct but it's an easy check.
I'll have a double check of everything today.
Any thing else it can be?

Most common failure of crossflow crankshaft oil seals are due to;
1, Not centering the timing chain cover with the crank on re assembly.
2, Not lubricating the oil seal lip during fitting. If you do not lubricate it on initial start up it is dry and the lip wears rapidly.
I have cured many crankshaft oil leaks by replacing the seal and lubricating the lip.

Do you mean to say all Crossflows DON'T leak? I thought it was the law.
