Fitting Piston Squirters
 

Any one had to fit thier piston squirters?

I'm wondering if I should use an epoxy or locktite product to hold the replacement squirter in my case. It has a reasonably snug interference fit, but not snug enough to hold it against the 50 odd psi oil pressure.

Advice?

You "stake" them. Look at the originals and you'll see where a chisel (ish) tool has been used to upset the metal around the squirter to keep it from coming out.

Excellent!. I did notice that, thanks Chris.

how did you get them out, and what is the part number?

I had mine replaced during my engine rebuild. I spoke to several well respected Porsche machine shops and engine rebuilders, and there were several opinions about securing these.
Some just staked them as per the factory. Some just used ultra high strength high temp Loctite, their reasoning being that if you try to re-stake around the edges of the hole, because of the heat cycling the aluminum becomes brittle and is difficult to stake properly.
I ended up doing both so I think I have the bases covered.
To get them out I think you use a 5mm drill to open up the end, then you use a 6mm tap and create a thread, then you should be able to pull them out.
Wayne sells them as oil spray valves I think I payed $27 ea, they come in a couple of sizes.

is it possible to add piston squirters to a 2.0 l engine block ? :)

I don't have it handy right now, but the part numbers for the squirters are in the Engine Rebuild book...

Yes!

and get the 964 squirters, they move a little bit more oil.

is there a procedure to do it ? what I need to know for this operation ? thanks :)
