Altering Xflow sump - with a hammer?
So, some pillock put a 1300 sump onto a 1600 xflow -rattle, rattle, rattle
Once removed I discovered that the interference between big ends and sump is tiny, merely scratch marks. I cast about for a while looking for a
suitable replacement sump, but to no avail. I then got to thinking why not simply 'form' a small bulge in the sides of the sump with
hammer and form or similar?
Is this possible? Will I deform the gasket surface? Would it be better cold forming or with a bit of heat? Anyone tried this before?
Any help gratefully appreciated.
Cheers
James

Don't see a great problem, make sure you don't thin the metal to much and check sump gasket face is level when you are done.

i didnt think it was good practice having your crank/rods constantly splashing through the oil, as is surely would do if they was hitting the bottom
of the sump?

There is a good chance of distorting the sump to block face so it won't seal.

Some power will be lost through this, and also you run the risk of foaming the oil. Sounds to me like there wont be enough oil in the engine either.

If your fitting a standard depth 1300 sump is it worth bolting the sump to a spare block, cutting off the bottom , modifying the sump to clear and
then shortening/baffling , that way with the mounting flange bolted solidly to a block any distortion will be reduced and ground clearance increased?
Vulcan engineering listed sumps on thier website a while ago as do Burtonpower

The big ends just clip the sides of the sump not the bottom, as far as I am aware the sumps are a similar depth so the oil splashing problem is not a
problem ( someone correct me here..).

Been there, done that... 
In my case, I'd even modified the sump before finding out that it was the wrong one...
In the end I bought the correct sump and modified that, rather than messing around with the 1300 one - which was a good thing, as I eventually sold
the old sump to someone with a 1300 xflow who wanted a modified sump. I just about broke even, if you don't count the time I spent in modifying
the first one.

Standard method for fix bashed sumps is with the sump bolted up to the block weld and a bracket on to the out side of the sump at the point you
want to pull out.
Then heat the bashed area with a gas torch to bright red, grip the welded on bracket with mole grips and pull the bash out.

Thanks for the responses thus far, some great ideas and thoughts. The sumps I had found for sale are generally overpriced and finding a rear-bowl
one seems to be rare. The reason for modifying my exisiting one is that it seems to be okay aprting from being ever so slightly to narrow, hence the
need for modification, and this is the 'low-cost' forum after all and time costs nothing.

I read on another thread that Mark Allanson had produced a PDF with instructions for sump chopping , does anyone know where I can find a copy?

You could take a look at my web pages re sump shortening - they don't qualify as 'instructions', but they might provide some useful
clues.
