Whats the difference between 1g, 2g & 3g lifters?

[dsmGSTtuner]

How can i tell if i have 1g, 2g or 3g lifters without removing them? I have a set of lifters out my old engine with a gaping hole on top. From what i understand they are the 3g lifters. Does anyone have any pics of them?

Well one thing to understand is the "3g" lifters are not from 3g Eclipses. The term 3g is just used. The "3g" lifters are revised versions of our lifters. Someone may be able to explain why they use the term "3g".

Anyways, here are a few comparison pictures I found online.
"3g" lifter and a 1g DSM lifter.

I believe these two pictures are of a factory 2g DSM lifter, and the 3g revised.

If they have the 3mm hole in the top then they are the 3rd revision of the lifter.

The latter two pictures are from my build and a little misleading. They mainly show the difference between legitimate 3G lifters (left) and Ebay 3g lifters (right). But, the much larger hole is what is to be noticed. I have never seen much difference between 1g and 2g lifters, they both have mere pinhole sized oil releif holes. The 3g and "revised" lifters have a much larger hole to allow for more flow. A clogged lifter is a noisy lifter.

I have always accepted that they are known as "3G" lifters becuase they are found in the 3rd generation 4g63: The Evo 4g63. But regardless of name, 3g or revised, they are the same.

okay thanks!! The info is well appreciated! Isnt there an easy way to change out the lifters while keeping the cams in? I have a set of 3g lifters and i believe the lifters that are in my engine now a the 1g lifters. Is it worth it to change them all out?

The main reason im changing them out is because i have this loud "clack" and i think its because all but one of my lifters are pumped up. One lifter i can push down with my finger..

I believe it would be well worth changing them out. The noise alone gets annoying.

You can buy this $35 tool to change them out like so.

I myself probably wouldn't recommend this way, but it must have worked for the guy filming the video.

Make sure to soak them in oil and bleed them before doing it too.
