Yes, I believe so. I think you'll find them sold as "NORMA" constant pressure hose clamps - you can probably get them from Haydn Callow.

Worth looking more closely at what you've got on the van - hard to tell from the photo you posted but you might be lucky and already have one fitted...? Here's what they look like...

The other type you can just about see on the big photo I posted earlier on this thread - the kind you squeeze two little tabs together with pliers.

Like I said though, take a closer look at yours to see if it is a "normal" hose clamp or a "NORMA" hose clamp ;) and you might just be lucky...
These are the ones to use.

They continuously adjust to expanding/contracting pipework dynamically.
Jubilee clips (and anything based on the screw fastening method) will not adjust dynamically.

Just had a look at the Norma site and they appear to be marketing a 'Jubilee' type product that claims to do the job.
This one:

Perhaps this is the one Haydn is now selling??????

Haydn, why have you changed to these?
Personally, I would stick to the original clips specified by Mazda.

I'm sure Haydn will confirm, but Norma link to this page and the part numbers match up with those in the photo I linked, so they appear to be one in the same.

Looking at the photo above, I think mine look like those, with the bolt through them. I will have to look at them all.
I have now bought a bottle of Gunk, to clean the engine. Just been out in the bongo
And it seems fine. Before I left I found one drop of oil on the floor, so maybe not s serious problem?

I think you may be getting confused with the power steering reservoir which is on the drivers side at the front of the inspection opening.

Does it get affected by cold weather?
Power steering fluid is what you see in this position highlighted in the red.....
& the one similar under the drivers seat to the front of the air filter housing is for the brake fluid....

The aforementioned stuff has nothing to do with the engine oil level...
But the dipstick under the passenger seat does.. Check level when engine is cold..!!
Jaylee would like to apologise for any misleading comments highlighted in red above... In retrospect Jaylee realises that in his keenness to post, (& after a subtle pm from a contributor on this topic.) 8) this action may have cause offence to some of our more seasoned technical contributors on Bongo Fury.. The power steering fluid reservoir location & the brake fluid reservoir location description locations were entirely the wrong way round.... :oops: #-o
With this in mind Jaylee fully admits he was wrong & would like to take the opportunity, making a heartfelt apology for any confusion or offence regarding this matter...! O:)

Jaylee would also like to point out that this error regarding the aforementioned post in misidentifying the two units in question does not reflect the personal maintenance program with regards to Jaylee's own vehicle, which is undertaken to the highest standard & utmost care.... :mrgreen:

.... Though i am a little concerned about the low air pressure in my gearbox...! :wink: :lol:

Just to make certain - its not the type of bolt that's important, but the overlapping bit of material that is on the clip itself, its what ensures the constant pressure that is applied to the hose itself.

Spent an hour under the van, and in the engine cleaning it with Gunk..lookin at it now
I think I see a few places around the rocker head (I think) where it looks like oil or fuel has seaped from.
Would this be the gasket or a something else?

See this link for how it's put together...
http://lushprojects.com/bongopartsmk2/c ... mgno=.html

Note that the grommet/spacer things (10-237) look like this...

Image

The ones on the left are rolled steel, the ones on the right are solid aluminium. I overtightened the ones on the left, and luckily the seam buckled rather than the threads in the head giving way. The torque is really low (<10Nm). Don't overtighten - if I understand correctly, there's not much pressure in there that the gasket needs to contain - try removing the oil filler cap and put your hand over the hole - there might be a bit of chuffing but not much.

If you can see the gasket between the rocker cover and the cylinder head then you could try nipping up the bolts. If the rocker cover is pretty much well down flat on the cylinder head then the gasket may well not be performing as well as it should - my new one was a couple of mm taller than the old one that I removed.

I think they can also leak towards the front where the gasket goes up and over the front bearing - if this is the case (hard to tell sometimes) then you might want to remove the cover and replace the gasket.

See what other feedback you get on here...

Matt.

Looked at the auto transmission flued level and it looks a bit low.
How do I top it up? And what with?

Ah - there's a trick to doing this - I think it's something like...

Warm it up - good drive - stop, park it, leave the engine running, work through the gears and then back to park (all with handbrake on), then check it. I might be wrong on the details - did you do anything like this?

Had the rocker gasket replaced. Still looks quite wet. Think I might pop into the Mitchell garage in garstang next.

It's probably OK then. The level has to be checked running. Dipping it with the engine off won't give you a true reading. IIRC, it's checked in D (handbrake well on, obviously!). Level on mine is pretty much the same in P and D though.
