Some people post swearing that they are useless, and the extra oil on the cylinder wall and bottom of the piston does more harm then good. These people claim that they should not be installed on an H23, and should be removed on the H22.

Other people claim that the H23 should not be revved above 6500 RPM even when built, and especially under boost, as the extra heat generated due to the lack of oil squirters will cause problems if you rev it that high.

build up in question: H23A, built & boosted.

 

 

I would also like to know.

 

Is this a street engine or race.If race 99% of engine builders plug them and alot of people do it on street engines also.My opinion,and thats all that it is an opinion,is to keep them.I believe the Honda engineers know more than most of us and they put them there for a reason.Just my .02

 

I take them out...I have a built N/A motor it seems like a waste of oil.

If you are running forged aftermarket pistons you shouldn't be worried about 'hotspots' as the forged lightweight piston should have good properties to prevent that, stock pistons get oil squirters for hotspots. I mean really hot much can hot oil cool a piston?

 

well, oil temps are several hundred degrees cooler then combustion temps...

True but 'm just curious how quickly heat will transfer into the oil and actually cool the top of the piston? Before it hits the power stroke again?

And why would you want to heat up your oil anyway

 

Keep in mind teh H23 didnt come with em anyway......wheres the logic in that where the h22 does and the h23 doesnt?

 

The oil squirters are there for a reason, whether built or not they are meant to help keep the components in the cylinder cool and to minimise detonation.

Satan: Im dissapointed in that response from you of all people. Oil is meant to lubricate and transfer heat from moving compontnets throughout the engine.

 

Leave 'em out... That oil pressure is best used in other places

 

I have read that the oil spraying is good for piston cooling which is very important in my opinion. Read the following site:

Yeah, and people dont realize that the H22 was designed to rev a bit higher than the H23 was. Higher rpms mean alot more heat can be generated. People who state that the oil squirters take away from other components dont know what their talking about. The oil squirters divert a very small fraction of a quart from the oil pan. If your going to build up an H23 and its going to rev higher than stock. Keep or add the oil squirters by all means.

 

the other difference is at higher RPM's it's going to be harder to get oil up in there and to stay in there... allowing it to reach the areas of the engine in that manner are alot harder. the squirters actually force it up in those regions on a more consistant and continious basis. This helps the life of the motor at higher RPM's and at lower RPMs as well.

Remember, race engines dont' last nearly as long as production ones, and to keep the motor revving higher and lasting 150,000+ thousand miles w/o a hitch takes some effort

 

Can someone post a pic of what oil squirters look like??

How hard are they to install??
