Thread: Oil Squirters...Absolutely necessary? I don't think so...

While I agree that they're there only to cool the piston itself, it still makes me wonder how well they cool the pistons. If people driving with a DE+T setup never have any issues, you have to wonder...

One of the primary failures of SR20's has been bearing failure, likely due to a combination of oil temperature, and lack of oil pressure. I don't think I can recall/count on one hand how many SR's have been pulled due to piston seizure/failure (not caused by blowing a hole into the top of one because of a tune related issue).

By removing the oil squirters, you run higher pressure (obviously, creating a restriction would raise the overall pressure) which would help to protect against lack of lubrication of bearing surfaces.

true but thats what higher volume ve pumps were designed to do. But you are correct because the det's use the same pump as the de's and have squirters so i could see oil pressure being lower than a de would be. Which like you said could cause premature bearing wear and failure.

But again a ve pump can solve all these problems. haha

Which is pretty much the reason I'm going with a DET block on my (eventual :cry turbo build

Tek, this is what i was thinking...........Thanks Cory

Anything to keep temps. down is a good investment.

look at it this way.

Take a piece of metal you just cut and douse it in water that is significantly cooler than the metal. How long does it take to cool down? Almost instantaniously.

Take that same hot piece of metal and just spatter water on it and see how long it takes to cool. Alot longer thats for sure.

Works the same way, The pistons without the squirters just gets splashed and speckled with oil from the the rotating of the engine and also from the oil from the rod bearings, the rod journals on the crank have an angled lip to allow oil that escapes from the bearings to be flung and sprayed upwards towards the pistons and also happens from pepetual motion from the crank spinning. But other than that the underside of the piston recieves no real douse in oi.

Now with the squirters its literally quenching the bottom of the piston with constant oil. This should cool the pistons significantly under high hp situations.

^You make a good piont Tekkie. Plus I will be running CP pistons which are stronger than stock DE or DET pistons. That is my piece of mine right there. Seems like it would be over kill with the squitters if you look at it that way, but some times overkill gives you double piece of mind lol.

You could definitely do without them (people makes tons of power on stock DEs), but I would never scrap them in an attempt to raise oil pressure.

Instead of scrapping the oil squirters to raise oil pressure, just put a spacer in the release valve of the oil pump. That raises the oil pressure and you don't mess with the squirters.

^^^ for a budget build though. If you build a motor then the price of a VE pump isn't gonna kill you. Especially considering that you "should" be using a new oil pump for a motor build anyways.

(Just another heads up for those who didn't see it, but there's a thread about the correct spacers to use when running a VE pump on a de/det. Very important. Just putting it out there)

^No way I would do that as my DE does not come with them anyway. I might just pick up a used set on the board for $40-$60 as a cheap investment/insurance . Again, I already have the VE pump.

I would not waste my time or money getting a de block machined for that. Jwt will do this but I iirc its not cheap. You would be better off getting a oil cooler.
