Dry Sump Pump
Looking for a low cost dry sump scavenge pump to fit to a zetec.
Anyone know a cheap supplier?

If I can, there's one attached to my engine maintaining the belt pattern.
Don't know how they would respond to being used in this way, though - a dry sump pump is designed so it is pulling air most of the time.

If I might jump in here, the scavenge pumps(s) which take the oil from the sump pan to the oil storage tank are designed to pull in air, the
pressure pump which feeds the oil around the engine is not. Practical Performance Car are doing a feature on dry sump systems at the mo and
they were/are going to demonstrate a low-cost system but, as I believe they mentioned in this months issue, do you really want to cobble something
together out of parts not designed for the job and risk destroying your engine if it fails, or would you rather shell out a bit of cash and know you
could rely on it?
I'd like to go dry sump from the peace of mind whilst cornering hard/better ground clearance angle but can't spare the cash at present.
ISTR reading that, unless you are using slicks on a track a suitably baffled wet sump will be fine.
NOTE: The author of this messgae is not an employee of PPC magazine and has just exprerssed his opinion, said opinion may quite well be total
bollocks.

if i read it correctly they (PPC) actually withdrew from writing an article using the power steering pump as they had questionable results.
My view is using dry sumps is supposed to improve the engines lubrication system in the harsh environment of spirrited driving therefore risking it
with an unknown pump is suicidal. You may get an engine cheap but the rebuild after wrecking it wont be.

I'm already going down the cut&shut baffled route but I'm not sure it will hold enough oil (is a home-made jobbie which should be good
for *about* 4litres - marginal)
Rather than splash out £450 (which I can't afford) on the raceline *wet* sump for the blacktop zetec (it's the blacktop bit that's
causing the hassle), I'd much rather invest £200 in a dry sump pump and convert my existing sump pan (a couple of hours work)

stevebubs,
Im sure i saw one on ebay not so long back. Motoring news may offer some contacts in the back. Failing that it'll have to be a new one.
You could also try the rally spares specialists. Do a search, theres a few about.

I've been hunting around and the cheapest I seem to be able to get at the moment is a used one at around £200 from ebay US (been watching the
auctions recently).
If I can, I'd rather buy from a UK supplier - and unfortunately I don't often have time during the day (usually only spare time is after
8pm) to ring round - hence my original post.
Cheers
Stephen

Whilst I am willing to defer to those with more experiance I would have thought that even in a worst case scenario that a failure
of a scavance pump would be most unlikely to cause catastrophic engine failure. My experiance with dry sumps is restricted to having had along term
relationship with a Norton . remember that your feed pump would be running from your oil tank and I think unless that was far to small that you would
notice two things , in the event of scavange failure , firstly the temp would go rapidly up because failure would most likely be due to belt breakage
and secondly your engine would produce LOTS of oil smoke . but I do not expect that it would go bang

having had one fail the 1st thing i noticed was the oil light and knocking noises, the pressure pump keeps going till the tanks empty n the sumps
full, yes the crank is running in oil but there's none going too the top end.
if the belt braeks, different story, no pressure either.
there was a thread on cheap dry sumps not long back, worth a search.

I'd seen that thread but even before it wandered off topic there were no firm recommendations on where to go for a cheap pump
