Valve reliefs 16V

I'll give it a go but one machine shop tried boring my VW block with a bridgeport, another one tried selling me a VW bloc as a volvo block, and another one I tried (actually a speed shop that did machine work) refused to work on a volvo block.

I'm wearing thin here lol. But thank you guys. I am going out of state and trying.

wow, that sucks.....

I was thinking more of a "real" machine shop that , not an automotive based one.
 
the first two were actual machine shops. C&D performance was the last try. He went out of business from taking on a bunch of FFR kit cars, taking money, and running.
 
You guys, sorry but it IS a fairly involved set up to hold the pistons without damaging them, get the exactly square to the axis of the machine, crank the upper part of the mill around, do the little ziiiiiiip cut, then reposition and do the second ziiiiiiiiiiiiiiiiiiiiiiiiiiiiip, then reposition the mill head for the other angle.

In fact it would be several hours all told on any mill all told.
On a CNC mill it would take less set up time but then you have progamming time.
And CNC machine time costs a lot more.

I wonder how many guys saying "It's easy" have ever run a mill doing an angle cut 16 times....

Anybody want me to post a clear drawing with distances and angles?
You guys won't understand it but a machine shop should make sense of them.

does a bear $@#% the woods?? Of course we'd like it :)
 
$150-200 with a 16v piston as a template gets you flycuts:



"B234 block with new Mahle 2nd OS pistons from FCP"

smaller cutter used than on the Ross piston I linked to....not a bad price, could have gotten it cheaper if more pistons cut at the same time...kinda hard to get a "group buy" on something like this....

OK, here it is in a good bit of cross border and cross forum co-operation thanks to our Canajian friend Hudson who was yakking with me over on the nice Rally site www.rallyanarchy.com

There. Real number. Not bad for a guy who really isn't even a Volvo guy, eh?

Maybe if some of the Forum Apparatchiks were like right on top of it, this could be added in the 16v FAQ things rather than disappearing into the abyss of the forum.

That is a bad price, I had some pistons fly cut for $55.00.

just cause you got a decent price, does not mean the other guy got ripped off, different markets and I thought you didn't need the reliefs, if your pistons are not cut the same way...your price it is not a fair comparison...

if you had the entire tops milled to remove material, big difference and a cheesy way to do things...

Hey Tex, look up the word 'pugnacious".
I don't know if you're trying to sound like a dickhead, but it kinda reads like you are trying to.
As far as you are trying to do anything.

Rather that being a twerp, why don't you HOW thpiston was cut, and in terms we might understand more than "fly cut".

Or not, no loss for us.
