When to Ditch the OIL SQUIRTERS?

[DSMsamurai666]

I was just wondering why some people ditch the oil squirters in the block. I know that with forged pistons the crowns of the pistons don't need the extra lubrication and cooling which is what the squirters do, but is there an advantage to removing them or is it just to get rid of the unnecessary? Also, can you get rid of them if you're running any kind of forged pistons or is it only when you have really good ones?

The short version is some people think they get stuck open and that starves the crank of oil at low RPMs so it develops crankwalk. Since forged pistons don't have to have them, taking them out should increase the reliability of the engine. If you search you should find some topics discussing it. Magnus Motorsports has a very good article.

If you have a 6-bolt, you don't really need to worry about the oil squiters. On a 7-bolt, the oil squirters are more likely to be removed b/c if they get stuck open they can cause crankwalk. So to sum up, most people get rid of the squirters just so there is one less thing that could go wrong.

True, kinda like balance shaft removal. Just one less thing that can fail.

I do agree with what everyone has said so far. Me personally have decided to keep mine and install new ones in my 1g 6bolt. Just makes sense to run cooler if possible. Alot of the time is rebuilds not having proper clearance and hitting then breaking them off or things of such during the rebuild process. I have had 5 different 6bolt build and never replaced the squirter and have had no problems. Guess it can go either way. Also magnus numbers are great but if only 2 a month in their area are going bad then it's pretty good odds there is nothing to worry about. 2 out of every 5,000 cars example.... pretty good number considering what uneducated people do to them.And the fact some are 15+ years old..

Hope this helps
