Re: 356 connecting rod oil hole

Her's a theory about the squirter holes being closed off . . . . It is just a guess as to why anyone would do such a thing.

Suppose a previous owner noticed oil pressure was lousy (- warning light comes on / gauge hovers near zero when engine is hot). Also notices clouds of blue smoke following him . . . everywhere he drives.

He takes off sump to see what shows up and notices plenty wrong. He decides to close off squirter holes to increase the oil pressure reading (- does car have a gauge?)or maybe to direct more oil along crank to all big ends and mains because the bearings are worn and plenty of oil is getting past them. Maybe the knocking lessens due to more oil between mating surfaces . . .

Or perhaps he reasons that 'less oil squirted up into bores means less ensuing blue smoke'.

He peens shut seven holes because he has access to them from below. Can't get to the eighth (- or doesn't bother, or possibly he can only count to seven). He then feels quite pleased about his 'solution' to the wear problems. (Pardon my sarcasm).

Could this be the case?
