Morning all,

Back from hols, and noticed this on my "what's gone wrong this time in the last 1,000 miles" check:

Looks like a small oil leak from that cover. Can't see it mentioned in the Bentley however? Going to check & topup the oil level if need-be to get me to CamperJam this weekend - if it's low, I guess I'll need to drain/replace seal/re-fill - but what seal do I need, and is this going to be a can-of-worms?

Cheers,
Ben.

OK, always the way, post question, immediately find out a bit more info - looks like the reverse gear cover (Thanks Brickwerks! https://www.brickwerks.co.uk/t3-parts/t ... yncro.html" onclick="window.open(this.href);return false;), but can't see mention of a replacement seal for it - do I just need to splash for a new cover, or clean up what I've got and apply some sealant manually (and if so, what's recommended)? Ta

Don't know what is there but I would just make a new gasket for it if you can't source a ready made one.

Good idea

My other thought - anyone know how torqued those bolts should be? Wondering if one's a bit lose.

Give Aidan a call, he will advise and as he's hoping to be at CJ and could possibly bring you a gasket if required I'm sure.

the bolts are M6, so 10Nm or 7ftlb, or tight enough they are tight but not so tight you strip the threads in the case, if case threads are damaged there is enough material in the case to go up to M7 I can supply suitable M7 bolts, also check original bolts are not bent due to scenery interaction
there's no gasket you use a good quality rtf silicon or flange sealant
if it hasn't been damaged from without then there maybe something nasty going on inside, you'll only find out when you remove the cover and see what comes out

Thanks Aidan, really appreciate the info.

Will top up for this weekend and then tackle properly next weekend. Box is smooth & changing easily, so fingers crossed it's just a lose bolt/missing sealant. Was 39C driving down through France 2 weeks ago, so hopefully it's just a result of it having got a tad warmer than normal...

Looking forward to meeting you in person at CamperJam if you're there
Cheers,
Ben.

Finally managed to get the filler plug out and get some oil into the gearbox tonight; Only 1/2 litre before it started overflowing (with the van on a slight side-slope, oil filler hole downhill), so not as bad as I first feared.

Found this helpful page on changing gear box oil for future reference:

That Draper oil funnel was an excellent recommendation!

Reverse cover bolts all tightened already; the cover's taken a bash at some point (the lip on the bottom of it has a sizeable dent in it once I'd cleaned it up), so will replace & reseal after CamperJam and hopefully that'll fix it properly.

Now... just to pack & re-load the van for the weekend!
