Man I've been waiting for over a week for them to send fed ex to pick up the new pistons that I ordered. To replace these pieces of shit ones.
Called yesterday and that I have to wait another week. BS I tell you.
First they send me the wrong side then they send me the correct side but dished although on the invoice they have the correct part number.

......right buddy. I find it funny how all of the probe pistons break in the exact same place.

That's what happens when the rings are gapped too tight + detonation.
The ring ends 'but-up', flex & pop the top ring land off.
Gap the new rings larger!

If you like I can see if I can expedite this for you and see what is happening. I can honestly tell you UPS & FED-X sometimes take a LOOOOONNNG time to do a merchandise pickup which sucks because it makes the reseller look bad. We have had this happen to us at my other business.. Surpluscomputers.com Please PM me your details if you would like our help.. I will need your Name, address, date of order, if it was pistons only or a complete block/engine, invoice #, who you have been talking to, and your phone number.

That sucks..
You really do not have to worry about them taking care of you. If the product is defective they will replace it. I have seen them replace a short block that was OVER 4 years old. Mark O'Neil (Owner of Coast/ Probe) is a pretty stand up guy and always stands behind his product. We have sold over 25 of their engines/ shortblocks and not have had "1" issue.

ring gaps were perfect right to specs. I had another 331 exact same stuff with the same gap (wider for the nitrous in mind) and they never did this in 10K. Even under nitrous use.

The top piston shows the cause. The ring gap was too narrow. Even .001" too narrow can end up like what you have there. The bottom piston just shows how detonation occurs with nice sharp edges left from the broken ring land.
Modded Lightnings and 03-04 cobras come in to our shop weekly with the same results. The added boost and resulting temps with a tight factory end gap = broken pistons.
And, keep in mind how flexible these stock blocks are. You might be surprised how much the cylinder walls can deflect under high cylinder pressures and temps.

Exactly. ![[Smile]](smile.gif)
What were the rings gapped at?
Different ring materials call for different gaps. Recomended ring gaps can vary greatly from manufacture to manufacture.
For reference I gapped my wife's 347 Perfect circle Moly rings (w/the same probe pistons in your pics) to .024/.024. Some would say this is too wide...I say it gives me room for error.....or a nitrous shot.
Honestly, if I pulled those pistons out of a motor I built, it'd be my fault for the ring gaps (if they were too tight), but your fault for the detonation. Either way, I don't see how it's Probe's issue unless they built the shortblock block....& even then it's questionable. Detonation creates tremendous heat, which in turn can close the ring gaps (even gaped on the wide side) & causes the damage you see.
Probe pistons are not pieces of shit.

And I will politely say that you don't know anything about building engines. Now before you go and tell me that you have built hundreds of engines, and this has never happened to you, look closely at the top piston in the picture. The piston crown is pushed UP above the top ring land. Since we both don't know crap, maybe you can enlighten us on how a piston can do this without the end gaps butting together, causing the piston to deform and break.

There is nothing wrong with Probe pistons. Probe probably makes some of the very best pistons for the money. Many shops in the area AND on this board use their pistons including HCI.

They were gapped wide.....
.028 top ring and .038 second.
All of the probe piston failures I have seen have come from the same area. Seems to be that by adding the additional notch for canted heads. It is in fact weakening the pistons.
Then to add instult to injury they have screwed up the order several times.

No doubt about it, Mark needs to 'kick some ass' in the shipping/packaging department. It seems 50% of the time we get the wrong parts.....sometimes even packaged in the correct boxes.
.028/.038 is definately not tight! Unless you were pushing a shit-load of power.
Still, the motor detonated severely which creates tremendous heat along with 'rattling' the piston in the bore.
The rings DID but-up, & there was detonation present. That is why the pistons failed. Any other piston (JE, Ross, SRP, CP) would have met the same fate in this situation.

a 5 yr old kid can do a better job at processing orders and getting an order right. they have PATHETIC customer service, and cant get shit right half the time or better. and for that i dont do buisness with them.

So we can all agree though that CHP has crappy customer service an they lack the ability to get an order right.
