Oil squirters/ piston oilers discussion
#61
100% street. Tried changing driving habits and absolutely nothing changed. This was my last attempt before next overbore, new rings... Glad this seems to have worked.
What PtW clearance and ring gaps are you running? Your Pistons do have the drain back holes near the oil control ring right?

The pistons have holes near the oil control ring, yes:

Same gaps as mine. My rings are wiseco XX. Is that what you have?
My PtW is .0036", .0037", .0038" and .0039". These were measured on the engine stand and it makes me wonder if on a table they would be a little closer together. One ten thousandth every hole out from the stand. A little loose, but I wouldn't say excessive.

Did you bore with a bore plate?

For what it's worth, I have Weisco low comp pistons, factory squirters, and run Rotella T6. I drive mostly street (sometimes hard) and produce a peak of a bit over 300whp.
The only oil consumption I seemed to have was when my tuner had the car for 3 weeks and was romping on in on the street and the dyno and during that time it needed an extra half quart or so. For when I drive the car, my oil level stays fairly steady (nothing that is concerning) and certainly not as bad as the OP had with his setup.
My motor is not the tightest setup either, so some use is expected. I even asked the tuner what he thought about the oil consumption and he said that for the power the car is producing and how he was driving it, it was totally normal. I had a habit of checking my oil level at work and always panicked about it reading low until I realized our parking lot is not flat.

Do the wiseco's have the drain back holes in the pistons?
I've made a habit of always parking in the same spot at work. Pretty level by eyeball. However more importantly I alway check it there so I can see if it has actually lost some or not. It really doesn't take much tilt to really throw things off.

The pistons did have some holes, IIRC where the oil control rings go.

Update: at 2200 miles since removing the squirters, I added one quart. So far oil consumption is roughly cut in half.
I'm thinking that hone and PTW clearance are the contributing factors here. Although not ideal, I can live with 1/2 quart in 1K miles. I may be going on a pretty long road trip in the next few weeks so I'll get to see if consumption goes down with less cold starts in between fills.

Installed and have about 500mi on new engine without squirters. Wiseco 10.5:1, coated skirts, .003" p2w clearance, XX rings.
Have been driving the crap out of motor during break-in and not a lick of oil loss, oil pressure is rock solid, oil temps have been more stable, and about 10 cooler than last motor. Aples to oranges comparing motors, but I am very happy with my choice to remove them for this build.

I'd say for sure, stock cast pistons, keep them. The pistons will run cooler, which will help keep them alive.
For Weisco's, I would not run them as they are not needed due to the alloy. They will not get hot enough to ever fail from temperature in normal use since they are much stronger at temp vs other alloys.
