Help!! piston rings for 3sge beams

[James Sen]

So I'm doing a standard rebuild on 3sge beams motor out of an altezza, I bought a set of genuine toyota piston rings, when i came to put them on the piston i saw that the 2nd ring and the oil ring are to thick and it doesn't fit on the groove. So i checked the the part (13011-88570) and thats the correct one listed for the engine. The pistons in the engine are the factory toyota ones.

So my question is that has anyone else come across this problem, or does anyone have this engine apart to compare the piston ring grooves compared to my ones, maybe theres something weird with my engine or toyota may have packed the wrong rings. can anyone help??

I have a left over piston in my garage somewhere, will take a photo when I get home tonight.

Hope that helps.

[James Sen]

hey man thanks for the pic, it does look identical to my piston, do you still have the original rings for it, just need to know if the top ring is the same thickness as the 2nd ring.

[Soiled]

Nah they're long gone sorry

Just measure the ring groove in the piston. Order some aftermarket rings with the ring sizes and bore size.

There were two variants of the RWD beams motor for compression ratio, so maybe the Auto motors (11:1) had a different piston ring part number to manual motors (11.5:1)?

I've got some pistons somewhere here you can compare against if need be.

[James Sen]

yeah thats what I thought at first but theres only one part number listed for the altezza beams engine, yeah if i can get a piston to compare with that will be great.

The 1GFE in the Altezza is also a 'beams' engine... haven't happened to get some 1G rings by mistake??

[James Sen]

its was for a 3sge for sure and plus the rings in the kit was for 4 pistons

Measure the ring gap on the pistons.
If you put up some measurements people may be able to help a little more.

[James Sen]

ok the ring layout on my pistons are 1.2 x 1.2 x 3mm and the layout on the toyota genuine rings (which are the ones specified for my engine according to the part numbers) that I bought were 1.2 x 1.5 x 4mm

sounds like gen 3 3sge piston rings

[James Sen]

which ones? the rings off my piston or the rings that I got

[Grrrrrrr!]

1.2/1.5/4 is gen2 & 3 3sge and gen 2,3 & 4 3sgte, prob gen 1 too, but i've never stripped one.

take the rings back and ask for another set. sounds like some one has mixed the ring packs up
