Hmm perhaps, you would have to go around the head studs. And back fill this original inlets.

Water ways are interesting as they all appear to be full of muck...

not enough antifreese me thinks

Good point mate, weirdly though this year when i stipped my engine down i had a load of brown _hit in the water and i made sure i had the right amount of Anti freeze.

Damage could have been done years ago...

I have been flushing my engine for a while but i cant get the coolant clean! I have used de ionised water and antifreeze mix but it still has a brown tinge!

Cheers Star mag, makes me feel better :) I'll give you a bell soon.

I would love to see some pics like that of the top of the block water ways.

I have started posting on Instagram also my name on there is turbomk1golf

Nothing is impossible it just costs more and takes longer.

Would be good to see a vertical section through the middle of the chamber, between the valves through the spark plug hole (if you know what I mean?) to see how much metals there for enlarging the chamber.

one day boost will be mine!

Verticalis the way i have one cut up. so i know where the meat is, but if i showed you , you would know too, abndwe can't have that,lol

WWW.FORCE-RACING.CO.UK PLEASE CLICK HERE

I did think that when I wrote it, I notice ppl on here sell modified heads....... Would be bad for business lol

one day boost will be mine!

I love cutting stuff up

As for antifreeze, I noticed the same. a very clean block and head but still got a load of brown shit in the coolant. I reckon some european legislation has caused manufacturers to change their coolant specifications. I don't think the blue stuff is up to much cop these days, and I am now considering only buying antifreeze from the likes of VW to be sure you are getting something that will work as intended. 50/50 mix!! as that will have the most inhibitor present.

I have also considered putting the Late Mini expansion tank back on the rad overflow, and then fill the rad to the very top. That way keeping the nasty oxygen out, that which causes the red rust in the first instance!

Nice one Sprocket, seems like i'm not alone, which i'm pleased with. Has to be some thing like you said as draining my passat VW that's doe TONS of miles, it's still the pinky colour with alomst no brown _hit.

Alu block and head though Matt. Same in both mine.

I too have problems with the brown _hit, even with the expensive stuff...

@Sprocket: is the VW stuff realy that much better...?

Alloy head on the VAG stuff, but I'm fairly
Sure it's all cast iron blocks still. Water never discolours in my vag cars either.

G12 is the vag anti freeze to use. I may start running it in the mini

Mr. Prawn, the friendly Crustacean- slowly making steps towards forced induction.

yes Prawn that was my point my VW has a cast block. could be the way forward :) Not cheap though if i remember.

The problem is that there is several technologies of coolant system corrosion protection, and choosing the right one is getting ever more confusing.

Many people will buy coolant from halfords, and look at their packaging. They have two types> antifreeze and Coolant, or, advanced Antifreeze and Coolant. The standard coolant is labled as for vehicles up to 1998 (IAT technology) which is blue/green. The advanced coolant from 1998 (OAT Technology) which is pink/red.

Looking at the products by Comma, whom promote what is in essence a BASF cetified product, they recomend for Mini/ Metro their G30 Xstreme product which is an OAT technology and pink/red in colour

Does it really matter? well I think it does. I have used only the 'blue' stuff, and while the colour is not the be all and end all of the story, the colour in most instances is an indication of the type of coolant installed. Im not so sure that the blue stuff available these days is any good, as I have suffered the brown shity coolant problem with the Halfords 'blue', as do many people these days using the blue. Never tried the pink so I don't know, but if Comma recomend it as a Rover Group approved coolant (which was used in the MPi) I'll give it a go.

Switching over to the 'pink' coolant, I suggested a VW product only in that it is a factory approved product that gets used in millions of vehicles around the world. There can be no bullshit in that situation. The VAG quality is very well known. You could try the halfords 'pink' but then Halfords are generally useless. I won't, not any more. I'll try to use a branded product with a name you can trust.

I seriously doubt it!

I've been using toyota pre mix coolant in mine since i rebuilt the engine, not changed colour at all! and i get it for free too

good point Paul, many people will say it won't make and difference, but until someone trys it you'll never know, But would think any gain would be to small to notice.

I would think it would have more value on n/a than turbo, but its all about getting gas in and out as fast as possible. Could be worth trying

I seriously doubt it!

but if you stop the flow there, then coolant either side of the blockage will be stagnant, and could cause localised boiling, soon as it does itll push the coolant out the head and you can guess the rest :) just a thought..
