odd question I know, but how do I do an oil change etc on a dry sumped crossflow?

Car is available to go to a place who knows or home to me to have a go, but as I don't really know what to do where a DS is concerned, I'm a little concerned of messing it up.

Any advice is welcome.

Not something I can directly help with, as I have a wet sump...

But, this may help: http://www.drysump.com/DrySumpInstructions.htm

Depending on the tank there could be a drain plug or not. If there is a drain plug simply remove it and drain, if not it can get messy because you have to remove the hose from the bottom of the tank.

The sump will have a drain plug in it, remove it and you will drain a small amount.

Replace filter filling first.

Refill tank.

After an oil change I always used to remove the plugs and spin the engine on the starter to ensure all the hoses were full before starting the engine.

One chap I know with no drain plug in his tank had invented an alternative method which I would not recommend but here goes. He used to remove the top hose off the dry sump tank and with the hose in a suitable container start the engine watching the oil level in the tank. When the oil level reached the bottom he quickly shut off the engine. Then he drained the sump, changed the filter and refilled the tank after refitting the hose..

thanks, not sure I'd chance the alternative method!

Thankfully the 7 will be sorted soon by someone who knows what they're doing (i.e. not me) but I'll maintain it as and when.

Just remove a scavange pipe connection from the sump scavange rail....this will let the sump drain of any oil still in it.

I had to drain my Pace/Brise kidney tank system recently, if the pump is as it should be there won't be much oil drainback to the sump in fact, in which case just undo the lowest pipe connection to the tank and let it drain from there.

My Brise tank has a drain plug but as it's about 3" up the tank it's particularly pointless.

It'd be really useful to have a trolley mounted pump with electric motor.....I was thinking about getting some made, which would allow deep filtration of the oil in a car without pain.....

Just stick the pickup down to the bottom of the sump via the tank cap if drysump, or the dipstick hole if wetsump, switch on, return pipe to either a clean 5 litre container or direct back to the engine, switch on and your oil is deep filtered down to under 1 micron.

It's far to sensible an idea of course, no-one would be interested in using such a thing.
