Yes, apparently so. I've never seen one, but from what I've read on 3si, they can be troublesome and most advise either using forged pistons and ditching the squirters - or - replacing them with new ones at every rebuild. They aren't expensive, so I don't know why anyone wouldn't replace them instead of rebuilding and keeping the same ones. Apparently, the only rationale for using them is to cool the crowns on the stock cast pistons.... forged pistons can get by without them.

As low as oil pressure drops at low rpms on our engines, I don't want to add anything that reduces pressure or flow, so I won't use any squirters at all.

What I'm finding so far indicates that the 6G72 block survives nicely with aftermarket rods (no rod squirters) and no block squirters if you use forged pistons. I even saw where one fella's mechanic had used a hammer and punch to close up the rod squirters in a VR4 engine. <img src="/forums/images/graemlins/scared.gif" alt="" />

It seems to me that eliminating the OE rods should raise oil pressure in the engine and benefit the top end oiling - maybe even driving away future lifter tick demons. <img src="/forums/images/graemlins/wink.gif" alt="" />

So, unless I find anecdotal evidence that convinces me otherwise, I'll use the 3sx rods with no squirters and hope I get enough splash and mist to oil the cylinder walls.
