Replaced the oil in my Ariens snowblower for the season yesterday by
draining it out thru the
drain tube they have on the bottom of the engine. The engine appears to be
an AL block.
Had a devil of a time loosening the plug at the end, and finally ended up
having to remove the complete draintube itself from where it is screwed into
the engine block. Has NPT male threads on both tube ends.
Anyway, might have been a bit too ambitious in tightening it back into the
Head a fairly loud "ping", but it still "seem to" snuggle up tight into the
block, and no evidence of stripped threads.
No discernable oil leakage anywhere.
Probably getting a bit ahead of myself in worrying about this possibility
now, but thought I'd ask:
Think it's likely the male tube going into the block a bit too much (as it
has the tapered NPT thread)
split the Al block at that point ? The noise of the ping I heard makes me
Or, perhaps the noise was a thread skipping, or... ?
Main question: If the block is split there, can it be re-welded ?
