T25 Campervan - Weldathonivangt6

Engine plans sound interesting, I'm looking to upgrade our T25 engine at some point too. I'd considered 96mm pistons and cylinders, briefly thought of a little turbo, but settled on a pair of 36mm Dellorto DRLAs or Weber IDFs. I'm struggling to find short manifolds though. Long term I'll probably ditch the type 4 motor and build a big cc type 1 motor, possibly a 2276, maybe slightly smaller, depending on what parts turn up. I'm looking at Mercedes steel wheels at the moment in either 15" or 16" but travelling to get them is tricky... Commercial or load rated tyres are so much easier to get in those sizes! So from my limited air-cooled knowledge I'm think my 2 litre cu engine is a type 4. What are the advantages of going to a type 1? Isn't that an older design? I'd love a pair of twin downdraught webers but given the milage were looking. at doing I'd like to keep it simple. Very tempting though. It might happen, we'll see. How much of the engine build will you be doing yourself? I was thinking with these being quite simple engines it would be a good place to start learning to engine build. Obviously I'd be getting all the machine work done but I'd like to assemble the rest Merc steelies are a good shout. I recon granada steels would be pretty much bolt on. I do quite like the standard wheels on this. Maybe banded a tad wider with the original hub caps and lowered a little. I really need a drivers door at the moment but as you say getting one with the current restrictions is a nightmare. Probably going to have to fork out for delivery. I'd rather lick a tramp.

Yeah, the CU is a type 4. They're the engine that VW developed to address the flaws of the type 1, but in doing so created a few more. The biggest downside that I see with them is parts - they're expensive and harder to get. Theres also the issue of experience and advice as many more people have built type 1s over type 4s. I'll be doing mine myself once I've had the machine work done. Drill the case for a full flow filter, have it machined for bigger pistons and a longer stroke crank, but you're still building it the same as you'd build a stock motor. Bigger valve heads would be nice, but not essential. You're not looking for a 200bhp, 8000rpm drag motor, more a 120bhp, 5500rpm torque monster. A pair of twin downdrafts will improve the motor all round. In my Ghia I swapped the original single 34 for a pair of 36 DRLAs and picked up over 30bhp and 4mpg!
Merc steels have a centre bore of 66.6mm so they'll fit on the front hubs OK. I think Granada ones are smaller, even though the pcd matches. Need an ET between 31 and 37 I believe.

neilsdaviesAh that makes sense. Ill be building the cu engine just because it's what I have. Like you say, I'm not looking for big horsepower, just something that will produce some decent torque and stay cool. At 70bhp as standard there must be some easy gains without spending a lot.

The roofs off! I did try to take it off nicely so I could sell it but what's left of the screws had turned incredibly hard and it was a paint trying to cut through the wobs of bathroom sealant holding it all on. So the power saw came out. R.I.P roof. It's about as bad as I expected underneath. Everywhere a screw was screwed into the roof has rusted away. Left side Right side My options are A) to try and get a roof chop from a panel van and replace the whole lot or B) carry out some more localised repairs. For the minute I'm thinking of going with plan b as the guttering is actually really good. It's just the skin above it and that will be covered by a pop-top roof once I can track one down It really needs a roof above it now

I’d go plan A, there’s a lot welding on your roof and compound curves and distortion and ...

I’d definitely swap the whole roof. Did it to my mk1 golf due to similar. So much easier in the long run. Grind out the skin only and plug weld the new one on.

Yep, new roof cut would be easier - we scrapped an '86 due to the same sort of roof damage. Looks like that was a factory sunroof roof pressing though.

If you want it perfect then its probably going to have to be a new roof but it's perfectly possible to make a sound long lasting repair that 95% of people would never notice, especially if you are fitting a poptop and/or roof rack.

The bath sealer / silicone / curse word whatever may be making the current situation look far worse than what its is - I would have a clean up of it first to see the real extent of the work before making any decisions - I have repaired worse before today where a roof skin has simply not been available in any form - but from what I can see there is a fair number of repairs to go at - I would also pop the windscreen out and check the state of the roof aperture - again before deciding what route you take - either way you may require a few brave pills - buts all doable in the grand scheme of things

That doesn't look too bad and if your fitting a pop top then it may hide a lot of it even if the curves arn't quite right.
Ideally get the pop top first so you can check that it fits the repairs as you go.

I get what your saying guys and if it was going to be a tin top van then I'd replace the whole roof. The reason for plan b is that the roof will never be seen again once the pop-top roof is on. So it doesn't matter if the roof warps a little. Even if I did fit an immaculate new roof I'd only be chopping a massive great hole in the middle anyway.
The majority of the roof is actually OK, the passenger side being better than the drivers side. The bathroom sealer makes it look worse than it is. The windscreen is staying on for now as the van is open to the elements until I can get a roof on the carport. Once that's in place it will be stripped out.
I would rather not disturb the hundreds of spotwelds attaching the roof to the guttering as they are rust free and have done pretty well. By opening up a good seam and puddle welding into it, it could be more likely to rust in future.
The sides are easy enough to make panels for and the front corners with the compound curve can be sorted with a body chop from another van.
There is logic behind the madness!
The roof is a job that isn't going to be sorted immediately, there's other areas of rust I'll be dealing with first and I may well change my mind as the project progresses. I mean if a good roof turns close buy then maybe it'll be swapped. But I'm not going to be hiring a van to drive cross country to get one

Friend of mine did a roof swap on a bay window camper. Gone for the same reasons as yours, but all of the internal structures above the glass were also completely rotten (like wet bran flakes - horrific), which made swapping the whole top a no-brainer.
It was a mission though. Not helped by the donor roof having some significant differences. Came out well in the end.
Same man has also just swapped the water-boxer in his late T25 for a 2L Subaru lump. Seems to have been effective, but he’s not long finished and test opportunities have been limited!
Obviously the Subaru route is much less attractive when starting from air cooled.

I understand your approach to the roof. Makes sense to do it that way to me. I can picture the old roof floating gently to earth and landing perfectly on its back as in the pic...kinda like one of those seed pods that whirls down to earth and lands ever so gently! JP

I know its spelled Norman Luxury Yacht, but its pronounced Throat Wobbler Mangrove!

JP I would be more inclined to use words like "unceremoniously", "crashed" and "ground". Maybe picture that instead 😂 I think the van is thanking me for getting rid of that heavy tub of lard from its roof

I have been plodding along with this behind the scenes. Admittedly it's been slow progress but it's an expensive hobby. After the roof came off the bus moved inside the garage. Bit of a tight squeeze! A drivers door was acquired to check everything lined up and then some more rotten metalwork was removed Front quarter panel and wheel arch panel acquired and the test fit looks promising. There is however some crash damage behind the front scuttle that needs sorting before all this is welded in. So off it came You can see here the extent of the distortion in the panel behind the scuttle. Difference between passenger and drivers side Some hammer and dolly work will be required to dress the damage and then there are various small areas of rust that will need cutting out and replacing. More soon

Excellent work on this! Keep going!
Having just bought a T25, and realising they rust EVERYWHERE, this thread has been really useful in understanding how the panels fit together so thanks for the info!
Keep the updates coming!

Nice work well done. Extremely thorough.
I hadn’t really thought how a minor bump could be really involved to repair on a bus like this.

Started dressing the worst of the damage out From this To this Then cut this corner piece out Which inevitably reveals more rust Nice, simple piece to make Rinse and repeat for other local areas of rust No welding gas so can't weld them in. So instead I ground down any remaining spot welds and treated any surface rust
