Dude, I totally wasnt. Look at post 19 and tell me where they hit.

Every FS-DE has them.
Just took pics and measurements of an engine I built with Pauter rods and Arias pistons.
Pic 1 - a shot of the oil squirter->piston clearance with that piston at BDC
Pic 2 - a paperclip in between above oil squirter and piston
Pic 3 - a measurement of the paperclip.
It appears that we have at least 1.1mm of gap in between the two.
Clearly, there is ample gap. It appears that for these pistons to chop off an oil squirter, the skirts would have to be at least 1.1mm too tall, which would be WAY far out of spec for a piston. There is a much greater chance of the issue being related to something besides the piston.

ok so back to my original statement that you pooed on, what IF ONE of the sets of pistons is bad, its not hitting at the tip of the squirter, it is hitting it at the base. We can see where the piston has come in contact with the oil squirter.
Look I dont know what you think im trying to do here, I dont want to s*** on arias pistons cuz they are quality, I asked a question if anyone has had success, I asked you a question via IM, and you instantly started to blame sam. I just wanted to know if anyone has had the same problem because I<~~~~~~~ am purchasing pistons for MY<~~~~~ Build. Thank you for the pictures I doubt the pistons would expand enough to make up 1.1mm so my guess is sam got a bad batch.

Why not take the measurements before hand to prove the claim right or wrong?
Also, be sure not to press the oil squirters in further than spec. That's another potential cause for his issue.
PS - I just compared a set of Arias pistons to a set of CP pistons, and the Arias have even deeper reliefs than the CP.

What are you going to measure? a broken off stub?
The jets were installed exactly like the other pictures shown here posted by you and max mazda. They pic with the indentation circled shows even it was positioned at the lowest point on the cut out relief. Max's pic is even depicting how it is installed stock by the factory never being removed. They were not pushed in too deep.
If you want 2 more comparisons to stock/factory pressed oil jets to compare I will take pics of Blake's 2 untouched engines tomorrow when I tear them down tomorrow. The stock piston even shows you the piston crown is angled downward to accommodate the jet arm. I'll take a pic of that to illlustrate.
Mine cleared on the test crankovers manually. Obviously, they didn't once the engine was fired up and run and the pistons expanded. Dino, you even had a squirter that fell out out of no where recently. Did I go, "Oh you put your motor together you messed it up! It's your fault!" No, I didn't because I have the respect to give you the benefit of the doubt you know what you are doing.
This is not the first motor I've built. I've done way more complex engines such as the VG30DE and other Honda motors. Give the installer mistake/error excuse a rest. I'm not inexperienced around mechanical engine work.
I've already spoke to Arias and they offered to shave it down for me but wouldn't rebalance it so I said no I will just have my local machinist cut it down and rebalance it. I don't have the time nor the patience to send it back and wait 2 weeks to get my car back up and running.
I personally didn't want this to get out of hand because of what you are doing here, blaming installer error because these are your spec pistons and assuming this is tarnishing your product. I was resolving this myself behind the scenes.
Blake knew about this because he is local and he talks to me at meets, so he was inquiring if anyone else had any iproblems before purchasing. He was really about to buy them anyway through me from Ken, but you basically turned this sale away with your response to his post.

I had a pretty good amount of time invested in Sam's motor on this most recent build. I don't understand how the squirters came in contact with the pistons at all. We turned the crank multiple times TDC to BDC. There was plenty of clearance at the angle we positioned them. I don't believe they were pressed on too far, we still had a bit of a gap between the block and bottom of the head of the squirter. In my opinion, the best option is to have our local machine shop grind the pistons near the squirters and have them rebalanced. Sam's set of Arias pistons aren't the only ones that have sheared the oil squirters, I've seen a few other forged pistons do this as well.

Well, yesterday I took a look at the pistons with Dino, and they cleared the squirters with a decent amount of gap. I would have returned the pistons for a brand new set of pistons to confirm whether or not it was the pistons itself. Like you said you're on a time scale and just don't have the time, but if there was anyway to wait it out, I would.

Bend them by hand to clear before installing..

What if the squirters were bent?
