Questions about dry decking
Turbo Mini Forums

Do you block off the water ways on the head AND block? to make the deck completely dry? Or do you just do the block to stop the water flow between them?

+ am i right in guessing that the heater take off at the end of the head would not work as well with this mod? So would a metro thermostat have to be used with a spacer plate?

+ any idea's who could supply the parts to go from a core plug diameter down to normal 1/2 inch pipe? Or would this not flow enough?

And finally does anyone have any pics for me to oggle!

cheers!

saw the title, and was going to say ive got a nail gun you can borrow to save some time. obviously not that sort of dry decking then!

Roadster conversion kits on the way!

as far as I know its fitting brass plugs to both the block and head, then skimming after (in a similar fashion to the brass plugs already fitted to the head)

this then means if this part of the head gasket which normally seals this area goes then no water can escape at all

not sure on the other bits, all the engines i've seen that are dry decked have the loop your on about from the core plug to the head

maybe try B&Q for the fittings, and get your block and head tapped (& drilled) as required

hopefully someone else will have some better experience on this, is it for reliability that you are looking to do this?

cheers

pretty sure turbo phil has got this done, or something very similar anyway. remember seeing a pipe there while i was drooling over it at avon park :)

Yea Phill has done this, i have looked around his site and couldnt really find enough details about it to satisfy me!

i dont think phils is dry decked, its just got an extra pipe to improve flow

o right, i cant see how an extra pipe would really help at that end...?

Mine isn't dry decked, but the block & head are tapped and a bypass hose added. This is to improve flow around cylinder four. This years engine has certainly run a lot cooler than previous years.

Which tap have you used? The size that is. I was thinking of doing something like that myself.

why is it called dry decking?

Yes, Im getting there.....

because when the water ways between the block and head are blocked off the deck is well....dry

Vegard - I had it written down somewhere, i will try and find out for you.

Interesting.

Can we go into a bit more detail WHY?

There is obviously a bloody good reason for it. I just can't see it.

Bugger off, I'm getting there.

doesnt it improve head gasket reliablitily and cooling round the no.4 piston or something?

Cooling is far more evenly spread out, by flowing all the water through the block then all through the head as apposed to allot of the water going around just 1 or 2 cylinders before it passes through the head and out the thermostat

+ if your head gasket blows, all you will lose is your cylinder compression, no risk of blowing out all of your water and overheating/not being able to limp home.
