Interesting that you rule out valve stem seals and head gasket - 2 far more likely causes of smoking on a relatively late car than piston rings. How much do you consider loads? I had a fiesta van of a similar age and that used lots of oil (without obvious smoking or any leaks)

Steady on guys - It's easter after all!!! How about a comment on post 9. Better way to spend our time than having a pop at each other! :lol:

It's several things, but cost and availability is the main (I got my motors off ebay £8 each). They need to pull 200CFM at a test pressure of 10" of water. I would like to try one as they look very neat but they are expensive. I need about 200cfm (cubic feet per minute), so the 150mm duct...

I apologise, I thought this was a diy forum not 'expert'. However thanks for the link, it does look useful.

Indeed. Strange thing is, I am basing my design on a commercially available unit which is advertised as 240v 10amp.. However, I am not sure what motors they use and I am sure they only use 2. Do you think if I was to only use 2 motors I would get away with it? This would be 12 amp max, but...

I'm afraid this man is an untrained animal. 50lb/ft is more than adequate for wheel nuts, only kwik fit monkeys do wheel nuts with an air gun (unless they use the a torque adaptor). How does your ex's dad expect people to undo wheel nuts by hand on the side of the motorway??? As for the...

Connect an ammeter in series with the battery. You should see that there is a current being drawn. Remove fuses until the current drops right down. You will find that one of the fuses causes a big current drop, you then know that a piece of equipment which uses that fuse is at fault...

If the dyson pulls 15.27A on start up, how come it doesn't blow the fuse every time?

That's the kind of info I need FWL. I am building a flow bench. It is used for measuring the flow in CFM through car cylinder heads, carburrettors, exhaust manifolds etc. Basically the motors suck through the cylinder head and you measure the pressure differential across them. There...

they are standard dyson vacuum motors.... rated at 1400W

Hi All, I'm in the process of building a piece of equipment which uses 2 or 3 1400w motors, the motors will draw 6a max each - obviously making a total of 18 amps.... Can I safely pull 18 amps from a standard wall socket, or will I need to beef something up....? Is it just a case of...
