Piston oil squirter deletes are almost always done when replacing factory pistons with aftermarket forged pistons, and/or sleeved blocks, and aftermarket rods. Their removal obviously eliminates the problem you ran into with the squirter tube contacting the piston at BDC, but more importantly, blocking the passages means a beneficial increase in oil pressure to main bearings and cylinder head components.

[@inaNis_]

The thing with oil squirters is that they only activate at higher RPM once oil pressure has reached a sufficient level. They have a check valve operated by a spring that is set to a certain PSI, much like a wastegate. Once the PSI is high enough, the force of the oil overpowers the spring and the check valve opens. Even if oil pressure does drop, because they only open up at higher RPM when the oil pressure is already sufficient, it isn't an issue to the health of the motor. Oil squirters are great for reducing knock on higher compression pistons. If you want to see real proof of this, look at the turbo 3 cylinder Toyota made for their GR Yaris rally homologation car, which has a total of *9* oil squirters, 3 for each cylinder. In stock form the engine runs about 20 pounds of boost with a 10.5:1 CR. If that's not going to harm a motor, I doubt much of anything will with oil squirters. Though I can't say anything about removing them for the sake of clearancing aftermarket pistons.

[@CrazedPerformanceRepair]

@@inaNis_ Awesome points mad by both. I personally like oil squirters for the cooling factor. I feel the extra cooling is worth the slight hp loss they may cause.

[@stephenjohnston226]

I’ll say it again. The world needs more mechanics like you.

[@cliftonwimbush5774]

I just bought me an gen 3 block for my sn95 98 mustang gt. I am looking forward to learning some thing from your video

[@chuckram2188]

Nice work, good tips.

[@mtrefethen1]

Great stuff sir.

[@malloymotorsports780]

Fyi, your suppose to delete the oil squirters when you go to a 2618 forged piston. Why the heck would you try to cool a forged piston that is trying to get up to temp? also you mentioned nothing on line honing the block when go from a main bolt to a main stud. the torque is different and the block can distort differently. also the coyote crankshaft has been proven to over 1500hp with no issues.. save your cash for other areas of the build. I just when through all this on my Gen 3 build and it's a pretty simple engine that was well thought out.

[@CrazedPerformanceRepair]

No, line hone checked out pretty dang good. Metal must not move much under added clamping force. Yeah I realized the oil squirter thing later on. Being the first time playing with one I recorded the video as such as well. I'm no Coyote genius I just find the issues and address them as I find them.

[@pault4513]

Built many truck engines I always shake my rods meaning i will make sure after they are torqued they move a little movement free play had one one time someone took the engine apart after i torqued the rod it wouldnt shake figured out the other guy nicked the rod bearing journal that caused a high spot after i cleaned it up it was ok could have spun a bearing had i not shook the rod

[@jonelford4513]

My kingdom for a workbench.

[@geotard]

Doesn't change the molecular structure of the steel. Cryo treating, like quenching and other processes changes the crystalline/grain structure of the steel. More or less/grain increases or reduces hardness and ductility of steel. Cryo treating increases hardness and rigidity and reduces ductility. So less wear on journals and less flex on crank. 😀

[@rggt6225]

What are the torque specs on the bottom end? Thanks

[@MilushevGeorgi]

I reckon the coyote tick is coming from that uneven piston angle, it’s a piston slap

[@CrazedPerformanceRepair]

Not likely, only if the piston to bore clearance is too loose. Mercedes does the same offset pin along with others.

[@erwinkrolop8731]

Invest in a good set of Mitutoyo micrometers. They’ll pay huge dividends in getting your clearances dead on. Also a WIP cart would help a lot to keep parts off the ground.

[@CrazedPerformanceRepair]

Agreed, cart won't happen till my shop size is increased though. That comes soon. Moving next month so shop size will increase.

[@harrisonclark4382]

Holy crap. I had no idea how easy it is to screw up an engine build.

[@CrazedPerformanceRepair]

Yup

[@harrisonclark4382]

It seems like one needs a whole lot of experience and perhaps failures before they get a really good grasp of engine building. I have a sleeved coyote built by Tim Eichorn that rips, but man was it expensive. Would love to learn how to tinker with the coyote or even a LS engine. @@CrazedPerformanceRepair

[@CrazedPerformanceRepair]

@@harrisonclark4382 Iv'e deffinutily done my fair share of LS based stuff. This was my first coyote. Iv'e learned what to watch out for over the years for sure. Yes, some of those things were learned the hard way back when I was doing SBC stuff.

[@MaciusSzwed]

Why are the pistons anodised red? Is that supposed to be an anti friction coating?? Never seen that before..

[@CrazedPerformanceRepair]

I've done a lot and it was new to me too. Customer ordered the parts but my best guess is a form of heat resistance. Something like ceramic coating does. Didn't look or feel like it would be very effective though.

[@origionalwinja]

Gen 3 coyote dont have piston sleeves. there is a crazy "welding" process to "sleeve" the cylinder bore that cant be adjusted. i have a gen3 in my 18 mustang. if i do decide to change any of the internals ill probably go with a gen 2 block or the voodoo block (5.2L) mainly because i dont trust the new process of "cylinder sleeving" great job catching those interference issues.

[@pheonixfps9248]

Cylinder sleeving has been around for literally over 100 years. It's not new. They bore out the bore, removed the plasma weld, and insert stronger, more reliable darton sleeves. The plasma liner is very well known to fail.

[@origionalwinja]

@@pheonixfps9248 im fully aware that sleeving has been around for more than 60 second. the new gen 3 blocks have to be bored out to sleeve them. you're boring the block to get the same CID. thats bullshit money spent for something that shouldnt be a thing

[@albduke]

Isn't that hard to block and something else supposed to be combined For a good running engine with these coyotes I don't know what the combinations are

[@harrisonclark4382]

It’s not bulletproof. Sleeves definitely drop from time to time.@@pheonixfps9248

[@edgarmarcha2460]

Watching your piston wrist pin offset location, could this be the issue with GEN3 V8 having cylinder shears that cause oil consumption issues. If installed with wrong side orientation, on those plasma arc weld cylinders.

[@CrazedPerformanceRepair]

It would cause binding and premature skirt wear if installed wrong. That could lead to oil consumption I suppose. But that isn't likely going to happen from the factory anyway.

[@ssswdon]

I just wanted to voice my experience here. When you measure bearings, the vertical clearance and the horizontal clearance are going to be different. This is by design

[@CrazedPerformanceRepair]

Only if the bolts aren't fully tq down. Once the rods are tq down it should be very close to a perfect circle.

[@ssswdon]

@@CrazedPerformanceRepair Well, the rod and main caps/hooles are definitely round, but the bearings are not, by design. Under load from the power stroke, the crank will be pushed down from torque, and the horizontal clearance will decrease. They build in clearance for this on the bearings.This is why clearance is only measured at 90 degrees from the parting line. Here is the science about “eccentricity" in bearings - www.mahle-aftermarket.com/media/local-media-north-america/pdfs-&-thumbnails/cl77-1-205r.pdf BTW - Just sharing

[@mtrefethen1]

Would you mind sharing the ring gaps, crank bearing and rod bearing clearances you used on this engine? Also, I know where that rotating assembly came from 👎

[@malloymotorsports780]

let me get my spec sheet from MPR race engines that spec'ed my block.. going off of memory the rods were like .0018- .0020 and the mains are simliar. I will udate this tommorow when I dig up the sheet. Being the gen 3 coyote is dual injection traditional ring gaps are out the window. the factory top gap is only .09 and the secondary is around .033. I went with MAHLE powerpak pistons that use the factory ford rings. I went with .024 on the top ring and left all the other rings alone as they are already set from ford. I went with clevite bearings as king bearing QC has been down hill. if your going to be boosted keep the top ring around .023-. 026... I'm pushing over 1k hp and all is well. also the arp headstuds are the same as the early 2011 engines that used a long M12 bolt. and yes, I see the MMR red as well.

[@mtrefethen1]

@@malloymotorsports780 Thank you Mike! I just saw this. Appreciate the info.

[@queso2561]

@@mtrefethen1 ring gap will be specific to manufacturer but most NA builds run the top ring at .016-.018 and secondary rings are set to .019-.021 If you are running boost under 1000 hp then add .004 to both top and 2nd ring if you are running boost over 1000 hp add .006-.008 to both top and secondary rings. You can also contact Mahle or Total seal to get generic ring gaps for your bore size, but each engine builder will have there own "performance ring gap" the specifications I suggested would be best for performance.

[@JMAC479]

@@CrazedPerformanceRepair I would've went through the same as well. I watched a series on here with LS vs 5.0. The main reason is clearance as you found out. But you gain 4 or 5 HP as well by deleting the squirters.

Fair critique, not everyone can afford the fancy stuff though. If you listen through it you'd notice I said it's very fussy doing it that way. You have to be extremely patient in order to get even a decent reading but it's still not perfect by any stretch of the imagination.

Sadly soon all combustion cars and trucks including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing all conventional fuel stations to only one state operated central gas station per city or county. Car washs will be forbidden too because they are climate killers, now they want to slow down all the gas station pumps from 20 litre per minute to 2 litre per minute...From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called emissions and smoke crime.!!! (BABVVEN & TEBBVEN & BEFVO laws)!!!!!!!

I hope your wrong but that fits the globalist narrative of "you will own nothing and be happy" also the eating of the bugs. I don't think it will happen though. People are waking up and starting to fight back. There are only so many elites after all. There is a global famine coming though with all the over priced energy, food, etc. Once the majority of people can't feed their kids all hell will break loose. At the rate it's happening we will likely be at war before 2027 unless it changes back after the American presidential election. I won't hold my breath though. I think multiple civil wars are coming. America is far too divided right now and Canada, Australia, and Europe have some serious issues against their government. Unfortunately those countries aren't as armed as the USA. I feel bad for those countries. Don't want to get political on my channel but seems politics are effecting every part of our lives lately.

Fair criticism, but If you plan to build one in a controlled clean room more power to you. If you plan to build it in your own garage, then my content is much more applicable to what you plan to do.
