sorry nvm that post, i was thinking your using 4afe slugs
will they clear the oil squirters?

???????
I saw the rods... and just a bit of the skirts... it appears from your rod photo that the AE92 4AGZE has full skirts, and the AE101 has cut down skirts.... is that what you are trying to say????
Btw... if I might ask about your thread... how can a smallport make its power @ 7200 when the late TVIS engine uses the exact same cams but can only twist to 6600???????
Information is POWER... learn the facts!!
Why remove them oil squirters? They keeps them pistons cooled.
this^ is why i think your doing it wrong
I think get the oil squirters plugged is to get high oil pressure throughout the main bearings? I could be wrong though...
That doesn't make sense, the oil pressure wouldn't change, you would be doing more harm than good removing them.
dude.... dont remove the oil squirter's! they are there for a good reason.

All you'd need to do is put some clearance notches in the piston skirts
the 4AGZE pistons already have the notches....
Why I removed the squirters (2 reasons)....
1) there often can be a low oil pressure issue when using squirters - I've now had 2 direct experiences. All the earlier 4AGE(and 1st gen 4AGZE) never had squirters, they lasted hundreds of thousands of miles. When those engines/pistons fail(4AGE) it isn't usually a burnt piston, but a broken land that is often the culprit.
2) they CHANGE the engines balance!!!!! Think of the Dopler effect.... When the piston is coming down the force on the bottom of the piston is greater then when the piston is going up. This can cause weird balance issues. Now think of all the pistons with "changing" mass
I have no proof... but knowing Toyota like I think I do... the squirters were used because of owners who don't maintain their engines.

Keeping pistons cool isn't an issue affected by poor maintenance?
Although it does supply more oil to the small ends and hence the bores too.
You should not experience low oil pressure with the oil squirter's fitted IMO.
I don't think the squirter's were used because of owners who didn't maintain their engines. I think it would have something to do with cooling the pistons sufficiently and I would imagine Toyota found this necessary after they had the GZE slugs manufactured and tested them. It would have a lot to do with the metallic make-up of the pistons vs. temperature in my opinion. ie. there must have been a good reason for doing such, otherwise mr toyota would not have gone to the expense of fitting them and I doubt poor maintenance by owners was the "reason".
My 2 cents.
