    So after playing with me new toys all day I finally figured out why I’ve been blowing speakers and managed to blowone of the new tweeters as proof:doh:

    The power cables to my amps are fine, the RCA cables from my head unit to the amps are fine and the cables from my amps to my speakers are fine.
    The original cables to my head unit however are undersized.
    I didn’t think this would be a problem as I’m not using the head unit to power anything really, just the RCA outputs, serves me right for not checking before.
    Spent ages finding the cause and will be going to work with only 1 speaker working as I didn’t have time to fit the other one or hook up the sub properly.
    Still it’ll be better than having to use my phone speaker.

    Orange is the speaker signal yellow is the RCA signal.

    Not clipping signal

    Clipping signal
    You can see the RCA signal just clipping at its peak and how big an effect this has in the speaker signal.

    Which problem?
    Blockage, coolant leak, oil leak?
    Bypassing it is usually only a solution if you are getting oil in your coolant or vice versa, you have to cap off the coolant connections and join the coolant pipes, a bit of U shaped pipe and a couple of jubilee clips.
    You must cap off the coolant connection points on the exchanger though otherwise the oil that was getting into your coolant will be all over your engine.

    Yeah that’s what I thought it involved I’ve got oil in the coolant and I’m pretty sure it’s not the head gasket I’ll give it a go as soon as I can get a weekend off work thanks for your advice Graham.

    Also don’t bother trying to do it with the battery in place like I did at first, takes a few minutes to take it out and put it back and saves loads of hassle.
    P.S.
    I haven’t had to bypass mine, the oil leak was between the exchanger and the engine, leaking down and working it’s way round and passed the oil filter assembly, down behind the starter motor and over the crankcase sensor, had to remove the whole oil filter assembly to change the 2 flat edged O rings in between(not a big job).
    I changed the O rings on the crankcase sensor more than once before I realised.

    So decided to have a look at the rear brakes Today as there is a bit of vibration at the rear left of the van when braking from around 70 the vibration starts around 60 then stops once below 50ish.
    The tyres are in good condition, tracking has been checked recently and all the wheels have been balanced recently (leading me to find out my now spare was beyond balancing).
    I have tried tackling this problem in the past with limited success, more than 1 set of new drums and shoes have been tried and swapping sides.

    A couple of basic checks I haven’t done in the past (no specialist tools I’m afraid)

    Hub wobble




    Just noticed this, I’m sure the shoe should meet the piston more in the centre.

    Awwww man!
    Looks like I need to do a jack repair now.
    Don’t ever trust a jack alone people, always use axle stands or anything suitable to prop up.
    I got lucky here as it went as soon as I started this bit of jacking.

    The non return valve probably has debris holding it open, if you are lucky it might not be part of the piston seal.

    Managed to carry on a bit with the emergency jack supplied by Vauxhall.

    Gave it a quick brush off and noticed this

    That gap can’t be right surely

    Compared it to the other side of the van, oh dear!

    Will have to replace that.

    There is definitely debris in something, from this seal.

    I’m fairly sure this is the plunger from reservoir valve section and the non return from ram is this one—->

    Gave them all a clean out but it didn’t change the operation of the jack.

    Can anyone confirm my thinking or give me a clue as to what else it might be?

    Just noticed what might be a second bearing type seal under where the sprung one seats when I zoomed in on one of the pictures.
    Will have to have a root around and see if there is a second bearing under the first or if it’s just a trick of the light.

    No second bearing but.
    Opened the valves up again pumped all the old fluid out (not that old, still had the leftover fluid in the garage from about 6 months ago) cleaned everything again put back together filled with new(ish) fluid.
    Working again now :dontknow::laughing:
    Bit late to carry on so going to the pub, does the new face mask thing apply to pubs? I’ll let you know.
    Going armed anyway!
