I am having my 16v rebuilt by a local machine shop. I heard good things about them and trust there work. However, they took the liberty of removing my oil squirters, which I'm not so sure about. The guy says that with a turboed engine like mine, you want to keep more oil at the crank. He told me that because I'm using forged pistons, the extra heat disapation is not neccesary. Now this seems to be contradictory to everything I've ever read on this forum. The guy says he's been doing it this way for years with no problem. If I want him too, he will replace the squirters and cut an opening for them on my piston skirts. What should I do? Has anyone ever heard of this?
Thanks

Have them sunk into their holes more (coutnersunk?). That's what the machinist had to do on my hogged out 16v block. Oil squirters, rod/piston/crank clearance and no weird cuts on my pistons/rods/crank.

I say notch the piston skirts. Cooler pistons=cooler combustion chambers. You'll need all the cooling you can for a turbo motor.

Interesting. Where did you get your pistons from? My JE's had notches already in them. Those squirters are one of the nicer features on that block. I say find a way to make them work! http://****************.com/smile/emthup.gif

Keep the squirters bro! I hear that is a big plus on a turbo car. Some of the older 10v and 20v blocks on turbo Audi's had them so why take them out? Leave it, they are there for a reason.

Definitely keep them. The main difference between doing a DIY tubro on a Nissan SR20DE and the factory SR20DET turbo engine is that the factory block has the piston skirt squirters. While not a VW, and engine is an engine. If the Nissan factory thinks its a good idea for their engines, it can't hurt yours. However, I can understand where your machinist is coming from on needing oil since the oil to the turbo is something the stock block was never designed to deliver. You may want to investigate an oil pan with some internal baffling, and maybe a windage tray to help keep the oil pan full.

The pistons are made by a company called Venolia Pistons.
Well, I went back to the shop today after reading all your posts. I planned on having him put the squirters back in. He explained himself in more detail.
He said that keeping more fresh oil by the crank is important because (acording to him) rod bearings are the first things to fry on an engine like mine. The pistons don't need the extra cooling as much because they are forged. When you bore for forged pistons, you have to have more of a gap between the piston and cylinder wall than with a cast piston to allow for it's greater expansion. When forged pistons get to operating temperature, they expand less than cast. Because there is more clearance there, my pistons are less likely to overheat and freeze up.
Or something like that. I'm still trying to figure it out.
Anyway, I decided to go with his plan. I know you all told me to keep the squirters but I have a lot of faith in this guy. He has been building motors and racing for thirty some years. The shop comes highly recommended. I'm not sure of the credentials of this forum.
So I sure hope I don't have any problems. I'll keep you posted

Yea right the guys been building turbo 16Vs for years. Tha's why you see them EVERYWHERE. Truth is most cars don't have squirters. I had to remove mine on a stroker in a 1.8 block with Carillo rods because there wasn't room. I imagine it was just the fact the pistons wouldn't accomodate them. I would not remove them unless I had to.

He's been building quality race engines for years. Not neccesarily vw 16v's. But the general principles are universal.

I work in a machine shop and we speciallize in VW, and Nissan race motors. We add oil sqirters to any VW motor that we can (that is alowed to for that class it is in). On the 2L talk blocks turbos (ABA) that don't have the squirtes we always ad them. All porche motors have them. They are needed for turbo motos more than a N/A motor, even if the piston is forged. Venolia pistond are very good. Extend thier life by putting the squirters. If you wont alteast take our words for it do yourself a favor and call a pro VW shop like Techtonics.
Just $.02 from an Automotive Machinist.

Re: plugging oil squirters? (Fast_bunny)

sounds to me like your machinist just doesn't feel like notching your pistons to clear the squirters... if his main reason for pluggin those ports is to inscrease oil pressure/volume to the rods/crank, then i'd be looking for another machinist right then and there.
if i wanted to change the oil pressure/volume, i'd be looking at the pump.
sounds to me like this guy is getting lazy, and riding on his reputation. i know nothing about this guy, but i do know that it soulds like a poor excuse to justify something that is more important than the average guy realizes....

I understand your delimma. In fact, I've questioned the credentials of some at times. Heck, people have even questioned me, and that's fine. But having built a turbo 16v w/forged pistons, I still say there's no reason to ditch the squirters. I mean, they don't provide a large mass flow of oil, just a high pressure spray. You'll keep more than enough oil on the crank.
I upgraded my 1.8 16v to the larger pump (36mm?). Kris at velocitysport indicated that the larger pump was more than sufficient. Also consider that the turbo will draw more volume of oil away from the oil system than the squirters will. Just a thought, though. Good Luck! http://****************.com/smile/emthup.gif

Well, thanks again for all the input. I'm still not 100% confident in my decision, but it's already been made. I guess I will be the guinea pig. Maybe everyone can learn from my failure (or success).

I need a cluepon....do just some ABA's come with squirters? My roommates ABA block has them and my 1.8 16v has them. My plan is to do an ABA 16v (turbo eventually) and I want the squirters. Is there a way to identify which do or don't have them without pulling the pan off?
