How would worn bearings cause low pressure?
I've just got the new pump and all the backlash/clearances feel exactly the same as the old one! It's odd how the pressure suddenly drops when hot.
Thanks

So I changed to 20w50 oil and it was better for a little while, but as soon as the engine gets properly warm the pressure drops to 5psi no matter what the revs are doing.
Looks like a new pump is needed.

Pressure rises fairly healthily when revved to 2500rpn, about 25psi when hot. Not great but atleast it rises!

Hi,
I've just put a second hand 1.6 in a friends Polo and we are having problems; at cold idle, we have 60psi of oil pressure, but when the engine is thoroughly warm it falls to just 15psi at idle.
The oil is 10W40 semi synthetic. Would it be worth trying some 10W50? I know it's not an ideal 'fix' but the car needs to be running properly by the end of the week!
Thanks

Got this done today, used the trick with the Nut and the Straight edge and found that the mark I already made was spot on.
I then put the head on, complete with cam and already lined up with its own mark, and bolted it down. Had to make a small rotation on the camshaft as the tensioner threw the marks out a touch, but it's all sorted now.
Thanks fellas.

Bit of a basic one but i want to make sure i'm doing it right!
I've got the head off a friends polo, and due to belt-cover mods we have no timing mark on the bottom end.
Am I right in saying that if i get piston no.1 to it's highest point, the engine will be at TDC? If so i'll just make a new mark.
Thanks

13x6 staggered offset. Chrome isn't great as you can see but there would be cash for you too. Thanks

As I've said, I'll be making a strut brace to add some rigidity between the towers. Just not sure if it'll be a bolt-on, or if the brackets will be welded on. Anyway, I got these on Friday! I can only hope that one day, after a lot pf practice, I can be this good at TIG welding. To say I'm please with them is an understatement! As soon as I picked them up I took them to the workshop and starting prep'ing them for paint. This only really involved smoothing out the grinding marks with some 180 grit, as I then shotblasted them; Next was 2 coats of Aerosol etch primer, and then they were put in a small oven on low-heat for an hour The primer has stuck like sh*t to a blanket, so next will be Scotchbrite and Cast-Iron Grey to match the cylinder head. Aerosol painting has a bit of a bad stigma, but I've been having great results by thoroughly preparing parts and using etch primer. Also, the actual paint I'm using is an enamel, and once cured at 60 degrees for an hour it's as tough as 2k! Anyway, that's all for now. I've not got long left at uni, so I'll be home in 2 weeks and will be doing a load of work in the engine bay. Fungus.

Woah, thanks for the post Richard! You obviously know polos well!
I'm with you in terms of the subframe. Mine has just had a new valance, rad support and front inner wings. Got the 90sHa Outer TCA bushes and ARB blocks too.
Funnily enough though, a mate of mine just spun his mk2f into a kerb and shortened the distancee between the ARB mount and TCA mount by 2 inches!

Yeah I didn't see that panel adding much at all, but I will probably make a strut brace for it. That bulk head does little for stiffness as the front legs aren't tied in, The best way to improve the handling on these is to fit a ppp lower subframe it ties in the whole front suspension and allows the anti roll bar to do its job instead of frolicking about... pppNot cheep but a better investment that upgraded suspension guaranteed.. I've been thinking about one of those for a while, but they restrict how low you can go and it already scrapes on 13's.

Thanks guys. Just a little update; I'm going to be running CBR600 carbs on the new engine, at least until I'm walking down the road one day and find a pair of DCOE's and a manifold on the floor. Or just until I can afford them. It's pretty easy to make a manifold for bike carbs as they are sleeve-mount. This is made even easier on Polo's as the inlet manifold flange is at the perfect angle. So I drew some up after having a quick measure in the engine bay when i was at home. This gave me all the dimensions I'd need in the workshop, as well as a drawing from which to cut the Flanges. I went and talked to the Technicians in the Uni workshop, who water-jet cut the flanges for me in return for some chocolate Hobnobs. My 40mm OD Mild steel tubing had also arrived so it was time for action. I cut all the runners by hand to 107mm, as they needed to be 105mm when all done. So next came this; After turning down the ends and matching the lengths on all 4 pieces, the ends were ground ready for welding. I've dropped them off with the Technician who cut the flanges, he's gonna get them TIG'd up in the next few days. I was going to MIG them myself but I want them to look nice and neat. So that's it for now, I'll get some pics when they're all welded up! Fungus

Hi,
I'm after a Distributor for a 1.3 or 1.0 for a Mk2f/3, the closer to derby the better.
Thanks
