oil squirters

12606356 is the part number for the nozzles.

Midnightriderz24, where are you getting the work done on your block?

i took it to a place in bolingbrook. a few of my friends know the old guy running the machine shop, so im getting a pretty good deal for what he's doing to it

What is the name of the place?

[gectek]

ok did anyone ever successfully complete this...i have access to plenty of the squirters(there are 2 diff designs) and maybe want to look into this.

I have been thinking recently about them and they are a cool idea. I wont be doing it to any of my engines but that's simply because they are gen I engines.

But what I was wondering is if anyone had concerns about increased windage looses from more oil being sent above the crank and hitting the pistons and then coming back down and being hit by the crank.

[gectek]

well it couldnt be any more than the windage losses from the oil just shooting up there from the rods anyway. i dont think it would be that much, if anything i would worry about more PCV system operation due to increased oil temp, being that more of it cools the back of the pistons and carries more heat with it. and then it would build more vapors possibly...but i think that is all minimal issues really. i really wanna do it though, but i wanted someone else to pioneer the way...lol. i only have 1 block...maybe i could get a spare and try it

This does sound like a great idea... but is it really needed? Has anyone really seen much scoring on their cylinder walls?

[gectek]

scoring isnt the idea, it is the cooling effect and being able to run more timing and possibly cr and still stay cool in the cc

[Z26-T]

That makes much more sense to me . Wouldn't water injection be more "bang for your buck"? On lowering cc temps? Not stepping on the idea, I really do like it . But the problem with the water injection, really easy to put too much in, or tune your car to run it and then have your tank go dry.

[gectek]

yah, you are thinking of the wrong side of the piston...the oil squirters would work from the block side right by the cyl bores, and they squirt oil to the underside of the piston...water inj is ok, but too many variables. the oil would run all the time that the pressure is met that opens the check valve on the nozzle assy, unless you change the spring, then it would open at a diff time...plus when you inject water into the intake charge, you are taking up space that could be used by extra air, or by atomized fuel, and by cooling the charge you can also hinder the atomization of the fuel...why do you think a TBI setup really wasnt that good or a carb setup over port fuel injection...because the fuel takes up space and it can cool too much and start to puddle, esp on the TBI, you could see the fuel droplets on the back of the throttle plates and the bottom of the intake, i never liked that idea at all

yes running a cooler t stat can help lower the cc temps also, but if you get an oil cooler and run those jets, then that is better IMO because oil also acts as a coolant and not just a lubricant

[Z26-T]

Not really the wrong side of the piston, what causes the majority of the heat in an engine? The top side of the piston. Yes, you also get heat from friction, but not nearly as much. But everything is is totally right .

So has anyone figured out how or where we're going to tap into pressurized oil for these squirters? Does anyone currently use engine oil coolers on their 3400s?

[gectek]

no thats not what i meant. by the oil squirting onto the back of teh piston, it cools the piston and in turn allows it to absorb more heat over a given period, stay cooler, live longer, and be able to take more heat due to it being removed quicker. where do you think all the cc heat goes...def not out the tailpipe...i dont remember 1200* exhaust temps on a gas engine...

there are a few people that do...aaronGTR is one of them, he has a nice setup on his SC ga

[Superdave]

Just remember.. it sucks to hone the cyls with those damn nozzles in there.. lol

[gectek]

mine area already honed...just dont do like i did and forget to take the NEW main bearings out when you finish ball honing it...yah that sucked

See 1700* when towing with my dads 8.1...

But I get what ya mean, just giving you a hard time. Post up pics, etc. after you have them in.
