Hay guys. I was wondering, now that I've nicely overhauled all my struts, and drained and refilled the reservoir, can I flush out the hydraulic system before I put the struts on to save flushing the dirrrty crappy oil through them.??? Would it work to put a hose onto each oil line and crank her up, or would this do untold amounts of expensive damage???

Dan perhaps the way to go would be to turn in the allen key lock nuts on the top of each strut - this will prevent the oil getting in or out of the strut. Then refit them all, and just bleed the one strut at a time by turning the allen key out again. Perhaps the first strut will bleed most of the old oil out. But really I reckon it won't be much of a problem. I wouldn't try starting it up without the struts connected. It would spray all the oil everywhere in a microsecond, run dry, make terrible noises and put air locks everywhere.

DO NOT TRY THIS I tried it the other day, hooked up all the drain lines into buckets, started the engine. Seemed fine for 2-3 seconds and then started making horrid grinding noises from (I think) the hydraulic pump. I very quickly turned it off as I had my hand on the key incase anything went wrong. Hopefully I haven't wrecked the hydraulic pump. Any ideas???

It shouldn't have been running dry. I even put extra oil in the reservoir for it to pump through. I don't understand how it would be running dry. Is there any suggestions. Next step is to fit the struts and suspension when the bits come back and have a go at Peter's idea.

I retract my previous loud statement.
It turned out to be a air lock or something, You were on the money, Jeff. Thanx.
Anyway, I slightly pressurised the reservoir by putting some tight fitting hose into the dipstick hole and blowing into it as hard as I could while starting the engine. It worked and no more bad noises.
Makes me feel better about flushing it before I put the struts back on, It seems acheiveable now.

Are you thinking of resealing the pistons in the accumulator like Peter has just done. He said they only lasted a couple of months before emptying again?

Yeah. I've installed the new valves and bought the needle tool. I'll recharge them and see how they go. They still had a fair bit of pressure when I removed the screws. If they go down again then I'll have to re-seal the accumulators.
