A big dremel, burrs, flapwheels, emery cloth on a a bit of round bar, scotchbrite wheels and will get on to the finer flap wheels next get it really polished up. Can't wait to start on the head.

Did you know too polished is bad? Some paterna to the intake and exhaust create swirl and swirl is good it helps mix the atomised fuel and swirl in the exhaust helps it flow around the bends (and I don't mean Radiohead).

Nope, as far as I know the best thing for any engine is to be able to get as much air in as easily as possible.

If the port is too polished you get fuel droplet-ing. Which loses power. If the intake port is roughish, it helps the fuel /air mixture atomise better.

I second that Rich. Polishing Alloy Ports IS NOT GOOD. Remove all burrs and casting marks and lumps and bumps and smooth out around valve guides but DO NOT MIRROR FINISH. A lightly ground finish is best. The more you open a port up the slower the gas flow and  twin valves allow for higher gas velocity.
 
Higher gas flow gives you low down torque opening up the port ( not that I think that is what you are doing ) slows down gas flow and moves your torque higher up the power band and gives more power top end  but if its a work van then its low down grunt you want. 

Its worth buying an engine tuning book. You will find many useful power gaining tips in there.

Rich's Boss is World Famous Drag Racer and Engine Tuner Alf Hagon and he was famous for tuning JAP Engines ( J.A.Pearce ) not Japanese . I learnt quite a lot of tuning tips from articles in MCN that Alf wrote in the 60's and 70's.

All the best with your Bus Ellwood.                      Woody.

A trick that was used in Hagon tuned engines for porting is take a 1/4" or 6mm rod/old bolt or such like to fit your air grinder or high speed drill.
Remove head of bolt if using that then cut a 20mm slot with a hacksaw use slot to hold end of a strip of emery cloth and wrap tightly so the end trails DOR and hold in place with a little masking tape this will remove quite a lot of metal if desired and diameter can be adjusted to suit then to finish start the emery cloth off in the same way but after a couple of turns hold in place with the tape this can be a little tricky so a deeper slot and put it in at an angle once secure lightly wrap the rest of the strip (not the whole pack) and insert in the port then spin it up and it will give a very good polished finish with some texture and as Elwood has already said gasket matching is the main point to get first.

at the same time, modern injectors have a pretty nice fogging effect and don't cause the pooling like old jets in carbs.

Golf balls are dimpled for a reason though.

Cheers for the advice everyone. I've always P&P'd my heads whenever I have them off, if I've got time, and, touch wood, there's always been a noticeable improvement in performance and economy, my 2.0 Capri gained an extra 15 mph, 10%, but those castings were messy.

I never go cutting away lots of material or messing with combustion chambers because I don't understand it, it's too involved and I never have the patience to mirror polish anything so maybe I've just been lucky and it's coupled with the proper compression of a new head gasket, but anyway, thanks for the messages.

Bonjour, it's been a while but I'm nearly back. I knackered my knee and haven't been able to work on the bus but preperations have begun, the head is skimmed and back together after a lot of ebay messing about, the gasket set I got was junk, nothing lined up or fitted, but that's all done now and the throttle body cleaned up.

Does anyone have any ideas how much welding will cost for both sills and bottom corners of rear arches if I can get hold of some half decent panels?

Thanks.

Having not done a sill one a hijet I would guess a couple of hours minimum per side if straight forward. However you may find you need someone who can make bits up if you were closer I would say let me have a look as I don't mind a little welding it helps top up the tan.

Did the passenger side sill on my old van, inner wheelarch and the wee bit at the front of the rear arch, prob about 5-6 hours all in, wasn't rushing, I'm not on bonus Wink
Drivers side would be a different matter, no way I'd be welding in such close proximity to the tank affraid
It also depends a lot on what kind of job you want? Making the sills with the swage lines is time consuming, I'm not paying for my time.

Logi did you have bits of bodywork or make patches? I haven't got enough time or knee strength to even think about doing it myself at the moment. I'll remove the tank and everything else because I want to try and give the underside a good coat of something while it's being sorted.

Rich, I've got about £250 and I'm still looking for half decent bits if you fancy a trip.

Woody cut some panels off for me Haven't had the weather yet as 2 bits require windows out  and the other 2 are door open jobs.

With the emission control on a Hijet I would be less worried about welding down the drivers side than in the rear quarter of my Escort and I have done the arch by the cap and welded the chassis up where the filler pipe runs, so long as you know where the vent is it is all do-able within reason.

Elwood I could be talked into it my father in law is in Surrey and I'm only Essex so it could be done assuming your in Sussex.

If you want to see if you can get the panels from Woody or HJ a straight swap over should be doable in a weekend it's only if the digging finds anything else. Proper panels should be a doddle as pattern parts never fit just right last one I did was a Beetle floor pan took about 3 hours with help from the owner  scratch

Thanks Rich, I am in Seaford, Sussex. I've emailed Woody and I expect the digging will find more, I'm going to try and get her in my back garden over the next few days and I'll start dismantling and have a good poke while I'm at it.

No worries I had a look at the sills on our MPV I am assuming it is the 90deg panels under the sliding doors you are talking about if not can you put a piccy up please.

If you have a good poke with a screwdriver, and a grind back, you'll find that one is mostly rust.

Check the seams on the arches at the front too, and below the seat belt mounting point on the passenger side.

I don't doubt it HJ, most of this was revealed by wire brush, although the front wheel arch seams look ok I don't remember checking the seat belt mount. Do you think it's too much of a job?

Oh Blimey !!! You dont make it easy for me Elwood . Out with the 9" grinder again. Rich's panels were a cake walk compared to what you will need cut off.

 I am getting a lift over to the garage Sunday afternoon as I cant drive at the moment due to rupturing my thy muscle at the bone just above the Knee. Extremely painful even now ten days after doing it. 

I will look at the cut up shells I have and see where it will be easiest to cut out.

I know, I'm sure it wasn't anywhere near as bad as this a few months ago. Have you got any decent whole bodies, how much would I be looking at for a whole one? Sorry to hear about your injury too, sounds rough.

Having had a look at our MPV which is the same it maybe better to leave the door runner in place and do small patches as required above and replace along the length below it depends on how far away the weld can be made if the panel distorts it could make the door not slide properly and the drivers side the fuel tank out would mean it could be welded from below again depending on whats going to be changed.

Ok, here I am, my knee is still half knackered, torn ACL, torn meniscus and sprained, waiting for an op, buuuut... some good news! The other half of the bus is spot on, all the rust just wiped off. Other side still needs doing, can I have a bit please Woody? " />
