oil squirters

[zil40]

well i orederd pistons from wisco and they were not notched for the squirters i called them and they said to move them or notch the piston if i move them they will hit the rod to clear the piston i was wondering if anybody has just blocked them off i know they are there to cool and lube the top rings and cool the under side of the piston i just dont want to notch the pistons and cause a stress spot on them any help would be great

[warrantynazi]

I'd be hesitant to block them. I dont think a clean notch will give you problems, just make sure you dont leave nasty cuts. they dont need to be big, just clean.

[Liquid_Neon]

What would u recommend to notch them? my DE pistons lack the notch as well.

[kapower06]

you ordered the wrong pistons, They wont exchange them for the correct pistons? Im not an engineer but I wouldnt go chopping up my brand new pistons. I also wouldnt run with out the piston oil squirters, they are there for a reason.

[float_6969]

They sent you the wrong pistons. Also, I would be worried about getting the weights off. If your pistons weights aren't all pretty close to each other, it may cause problems

[zil40]

well i asked them and they said they were the write ones and they said i should just notch them i wold like to call them but i get off work to late and they wont email me back so i dont know what to do

[sydwayz]

its called a machine shop take them there get them notched and weighed cheap easy and correct

Still sucks that you have to do that. It sounds to me like they sent you the wrong piston and now they don't want to fix the problem.

[kapower06]

they sent you the wrong pistons. Im using the wisecos and they have the correct oil squirter notch.

part number is K630M830 for std. size or K630M835 for .020" over.

do NOT remove those squirters...

[zil40]

sorry to bring this up again but i have called wiesco and they now they say to bend the squirters out of the way or block them off i have looked every were to find out if thats ok nobody knows i know with handas you can do it even if they are turbod has anybody bent there squirters out of the way i would think they would break im at a lose here every time i call wiesco they refer me to a tek guy that is never there and i cant leave a message any thing would help guys i need the car on the road as soon as posibly

[float_6969]

Tell Wiesco they're full of ****. The squirters aren't made out of tubing, they're cast. Most squirters are made out of steel tubing.

Get the CP pistons, they work great, have the notch, and no run-around. Go here; http://www.raceeng.com

Their only drawback is the are of a higher silicone content so they tend to have a higher rate of expansion and will slap a little when cold.

[zil40]

i cant get ahold of them to get my money back

[float_6969]

That's ghey. I guess you could take them to a machine shop, or an engine building shop and have them cut the notch in the skirt. They'll just need to weigh the pistons afterwards to get the weights the same.

[zil40]

well i have talked to e few shops and they are woired to gring them because they dont want to make them weak so i think i will try with out the squirters i have built ls vtec motors that we turbod and they dont have oil squirters so i will see what happens wish me luck

[MeanGreenS13]

good luck when your engine breaks... do yourself a favor... take them to a machine shop, tell them to match the notch on your factory piston, tell them NO QUESTIONS ASKED

you will no regret it unless you dont do it... dont be stupid man, if they are there, they are there for a reason!

[S@nt0s]

i will have to disagree, the oil squirters are in place to help with cooling of the piston being force induction/high reving. when running forged pistons ( which run cooler) there isnt a NEED for the squirters but it doesnt hurt either.

[zil40]

runs fine with out them has been for a while now so i will run with out them untill it breaks

[S@nt0s]

Did ur machine shop tell u what they used to plug them?Bolt? Banjo plug?On honda's we weld them since the block is alum. But these being cast iron its a different story

[iliketocrash]

kind of makes me wonder now that i think about it. because i took my motor to a machine shop to be worked over and assembled and i had bought wiseco pistons to put in it and the machine shop put it all together but never mentioned if there was any issues with the pistons and i haven't run the motor yet. i think i might yank the oil pan soon just to make sure before i put the motor in this spring

[Fleemer]

i would rather hav eno oil squirters then grind into the piston :P

don't dink around with modifying a piston, when you introduce something like a notch or anything you change how stresses react in its shape and make it weaker and more prone to exploding.

i'm not an engineer or anything..

oh wait i am.. (not yet, couple for years ;P)

correct , you will be inducing stress factors that were not intended in the engineering of the piece.

agian unless your doing long runs with lots of laps your fine..

[Seishuku]

Ya.

Ditch them if you're running forged pistons.

Then again, I'm running 10PSI on 10:1 CR cast pistons with out oil spray.

But it's just an SR

[float_6969]

I'll see your 10:1 compression w/o oil spray on an SR and raise you 10.5:1+ compression CP pistons with oil spray on a CA.

[Liquid_Neon]

Ive got my squirters... and 10:1. I ended up notching my DE pistons, should go great!
