Ford Zetec Undercrown cooling jets
Turbo Mini Forums

righto, nic, any luck with those pics of your block?

am i right in thinking its similar to below?

(Red is the drillings, green the oil spray)



what size drilling would be adequate? 0.5mm? 1mm?

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

Sorry its taken me so long to get these, i took them the same day but my bluetooth wasnt working

No1


No 2


No 3


No 4


The drillings aim underneath the pistons towards the crown (obviously)
The only difference is 1 or 4 (i cant remember now, ill have to check) where it isnt quite possible to get a good drilling on it

The hole is smaller than 1mm, not quite sure what size, it is discussed in vizards book

(bugger i think ive number them around the wrong way but im too slow to work it out tonight)

Edited by Nic on 21st Nov, 2008.

That hole is bigger than 1mm, a 1mm diameter hole is fooking small.

They look more like 2mm holes, perhaps 1.5mm

its smaller at the other end

brill, thanks nic

I thought more and more the BMW oil jets are used?! I like how clever they are constructed and how easy to install.

oooh yes i like those,

nice and easy to seal with a copper washer :)

what bmw are they from?

I like the way Nic's block is done.

Trouble is, I don't think that I have the skill to drill a hole that small without breaking the drill :$

Those BMW jets are exactly what I was after originaly, why have we only been told about them now

TurboHarry, do you have any part numbers? Do they come with the bolt or is the bolt a seperate part?

I recon I can rework the zetec fitting to take these fairy easily :)

They come with the bolt which includes a built in check valve which opens at about 3 bar - this has the nice effect that you don't waste oil on idle (thats what I don't like on the bored main cap idea...) If I remeber right the thread was M8x1, of course I have the part No but not here at the moment - will post it when I am back on my homecomputer at the beginning of next week.

mine is the same as nic, and so far havn't had any problems at all. Then saying that they probably came from the same persons idea.

google German, Sweedish, and French.

should tun up what Nic is reffering too.

failing that Motorworks not sure if they will do them though (never been on thier site)

Motorworks is a motorcycle breakers/ dealer

oh well thought they did all bmw stuff.

fore mentioned BMW oil jets retro fitted in Zetec holes, not as good as it would have been if I had done them in the first place, but much better than the things I had

Sprox,

How big is the actual hole in the end of the nozzle?

half the size of the zetec

Did you crimp the Zetec jets at all as recommended by TD or fit them as they came?

Any idea which BMW engines used these jets then?
