Just a thought. I,ve never seen a "guide" as such but..... is it possible to
reverse the plate and bolt it to sump via say 2 bolts and drill remaining
holes using that as guide?.
Swap over to drill remaining two. Used to be able to get oversized studs but
not sure if still available.
Have a good Christmas

Hi all,

I have a 1600 with some bad oil leaks around the studs which hold the sump
plate to the bottom of the block. Some of them are quite loose and easily
come out with only finger pressure, so I'm thinking I may have to drill/tap
the holes out and get stepped studs, hopefully tightening everything up and
stopping the leaks. While I'm in there I'd lock-tite the studs in as well.

First of all, does that sound like the right way to go?

Second, and more importantly, how do I go about drilling these holes out
STRAIGHT?

The engine is in a Kombi so getting under it with a drill is not a problem,
but keeping the drill straight so the holes don't end up cockeyed is what
concerns me. Is there some kind of jig for a portable drill that could do
the trick, or some other magic method that one can use?

Just thought of a third question: Are stepped studs a better way to go than
helicoils?

Thanks in advance.
