I have an A+ turbo head and want to fit the mini heater tap to it but the hole is sealed for the metro type heater tap.
Can i simply drill through the head casing to open up the water channel or is specialist machines needed and is it best for me to take it to an engien shop.

Thanks for looking

Dan.

Simple answer: YES and you can drill it out yourself the screw holes should already be tapped.

yeah the screw holes are tapped, so i just drill the hole out starting with a small drill bit and working up? is there any chance of drilling through an oil channel or doing damage to the head?

Thanks for the reply

You're pretty safe as you are deliberately drilling into a waterway anyway.

Hi Guys...........
Looking at doing this myself, are there any pitfalls to watch out for such as swarf findinding it's way into the water pump etc?

Got a brand new med 1380 (just about to fire it up) and don't really want any *rubbish* floating around inside it.

you should really do it with the head off the engine, and give it a good clean out afterwards.

Small drill to get a lead hole then up in a couple of steps is probably the best way.

DJ's suggestion has given me an idea - drill a small hole and inject some grease through it to catch the swarf There's little point in drilling larger than the bore of the valve's outlet.

I used a vacuum cleaner to suck out all the debris. Worked VERY well. And no problems 7 years down the line.

Thanks for the suggestions guys...............

May fire the engine up this weekend while I consider either drilling tap out or using later valve and sandwich plate from a later car!
