shock!!!..an octopus question

Post by B-Hive »

Hey nice fresh look to the site..well done who ever was responsible

Well as i returned from my recent trip empty handed, I have had time to ponder the next step in respect to picking up the MK1 TRS.

By all accounts its seems that the octopus has died, BUT as I had seriously sufficient time to examine it whilst repoking tubes back into it, it really didnt seem all that crusty or split anywhere. That being the reason I was doggedly setting about putting back the offending tubes that had come astray, as I was confident that that would solve the leak.. This theory held up for only a short time as with a few KM under its belt the problem resurfaced..

This brings me to asking all out there....has anyone had any catastrophic fluid loss issues that was ultimately put down to something not directly attributable to the octopus but more so maybe a flat accumulator that causes massive pressure spikes in the system..

I did have something similar-ish with the GT but it was certainly no where near as aggressive and potentially pipe joint popping as I was getting with this new TRS. OR if the small octopus is plumbed a little bit tightly can this have a major effect on the return pressures in the other parts of the system..

Before having it transported up here or going across another time to try again, I think it would be prudent for me to be armed with AS MUCH information as possible.

Thnx team BX

If a seal has failed elsewhere in the hydraulic system it will let the return piping see full system pressure, which it is obviously not designed to take...

What was the tick time like, thats the only way to diagnose how healthy the accy sphere is on the car, the longer the time between the hiss sounds the better. The other alternative is to take it off & take it somewhere where they have a pressure tester to see how much is still in it. I suppose another area that might cause spiking is a knackered hydraulic pump, have you had a chance to listen to it, i'll go with the theory that the louder it sounds the more knackered it probably is, although that isn't necesserily always correct either.

Mulley ...Tick time was surprising good, and other than popping/leaking pipes the hydraulics were were good.. Quietest pump i've ever heard (or not heard, in this case)
..I have decided that I'm going back armed with a fresh octopus and install one in parallel to the old one. I have examined the pipe layout of the octopus and it really is quite simple. I'll cut all the pipes going in to the octo.. stint and extend them and feed them up to the fresh octupus which will sit in a significantly more accessible place. At least by now the system will have had a nice flushing with the amount of diesel i ran in it..

I will also take a fresh accumulator, as it has sat idle for 5 years.

Cheers

I believe our continental friends used diesel to do flushing as opposed to rather expensive proper hydraflush.

Out of interest, how much diesel did you put into the hydraulic system & how many miles will you have done when you empty it out?

YIKES!!!! Given the quality of the Diesel imported from Aussie refineries to NZ the last thing I would be wanting running through those black rubber pipes is Diesel. No wonder the pipes leak!

twas leaking litres of the stuff (LHM) so i needed to put something in to crawl it back to where it needed to be...it leaked no more nor less with the diesel in the system..

Ah good point at nz$1.50 per litre compared to cost of litre of LHM and easier to find I will remeber that for future referance.

However I would still not be surprised if you get some other Hydraulic leak as a result.

I flush my BX:s with diesel fuel every second year in order to get the new LHM into as clean system as possible. I have not noted any adverse effects even though the mileages are on the high side (the Old Lady recently passed the million kilometre mark). 500 km with diesel or 50/50 diesel/LHM mix will clean the system without causing excessive wear.

Now there's an idea. Everyone goes on about fuel prices, but diesel is still a lot cheaper than Hydraflush, LHM or the oft-overlooked price of engine oil. Imagine if we had to pay £20 for every 5 litres of diesel!

I had a shock today to see on my Fuel Card website the price of the cheapest (unfriendly to BX 91) was 0.1cents under nz$2, shock because yesterday I put petrol in the Auto at $2.34 some 31 cents more than I will get charged on statement thats including the 5 cent discount I get anyways)

Although I love my Diesel when I paid nz$1.07 per litre with a 35c supermarket discount docket :)

So yes Dollywobbler in an emergency I guess paying $5 for some diesel for a leak in the Hydraulics is worthwhile.
