Oil Pick Up pipe
Having shortened my sump, i now need to shorten the pick up pipe to match.
In an article i read, it said heat the strainer off and braize it back on further up the pipe (after chopping some off). Is there a way to avoid
braizing, can it be just welded or is this too hardcore for it?
Anyone done theirs yet?

I mig welded my pinto pickup but it was fiddly, the metal is thin and any holes might lead to sucking in air for lubrication. Its also pretty much a
'do it wrong, chuck it away' situation if you mig it. With brazing you get another chance. Having said that, mine worked fine!

There is no reason why you could not soft solder it on, as long as everything is cleaned up really well, inside and out. It would probably seal better
than mig, having said that, I mig'd mine!
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

I had to cut mine, as the crossflow strainer is crimped onto the pickup pipe.
After cutting the required amount out, I cleaned up the ends and held the two parts together, ensuring that there was a snug fit. The two end were
then held together with some tiny tack welds.
Once I was happy that everything was in-line, I silver-soldered the joint to make it air and oil tight. I used silver solder 'cos I had some,
together with the correct flux, but brazing rod would do just fine.
I would be careful about using soft solder - although it doesn't go liquid until quite a few hundreds of degrees, it does get soft at anything
over 150C (which is why it's not allowed in model engineering boilers, where water under pressure can get to 120C).
If you try hard you may find a hard lead solder called Comsol, but you need special flux for that. You may as well get some fluxed brazing rods from
Halfords, which work very well.

Thanks for the answers all. To use brazing rods, do i need a blowtorch or a soldiering iron?
Is guess a blowtorch to get enough heat... anyone confirm?
Thanks...

when i've done brazing its been with an accetylene torch, though probably get away with a smaller one!
on the topic, i just took delivery of my shallow ally wet sump from westfield and the pickup pipe it came with was brazed...

beware, I've got yellow skin

Yep - blowtorch, but a modest one may be sufficient. You need to get the metal up to bright red/orange, but the pick-up tube doesn't have much
metal in it, so any DIY torch should do (I used a plumber's style torch off a propane cylinder).
I suggest that you borrow one from someone, if you haven't got a blowtorch. If it isn't up to the job then you won't have wasted
your money!
BTW: don't forget to clean the metal up all bright, shiny and de-greased before you start, otherwise you'll be wasting your time.
Degrease the mesh sieve as well, otherwise you'll fall over in a cloud of smelly smoke!
cheers,
David
