im fitting some new piston rings, and ive noticed that they have a sort of ridge on one side, suggesting that they go in one way. any ideas?

by **Lloyd** » Sun Sep 20, 2009 5:39 pm

Put it to the top side. Should have had instructions that came with the rings

by **Vertigo** » Sun Sep 20, 2009 9:59 pm

sadly not. cant find anything on the net about it. surely someone knows? which way does #2 ring go in: ridge up or ridge down?

Im sure its ridge down, but don't take my word for it

there will be tiny mark stamped on the end of the rings that says what number or size or brand logo.. that will be up position.

If you can wait I will have alook at my BGB when I get home. Has all toyotas steps for rebuilding a 4age including ring alingment etc.

thatd be great, thanks. post here so everyone can see.

these rings are genuine toyota, and have a very small T in the position you describe, jaypines. im guessing that that side is the one that faces up.

That little 'T' tells you the oil control ring end gap should be between 0.15mm - 0.52mm

by **jaypines** » Tue Sep 22, 2009 9:30 pm

as in the illustration... code marks faces up.

great, thanks for the help. appreciate it.

just a thought, could you perhaps send me that book? i can put it up somewhere to be hosted, for others to grab too. i assume its on your pc?

by **thegreatestben** » Mon Sep 28, 2009 8:26 pm

It's hosted on a few sites I downloaded it years ago now.
Its the BGB for AW11 MR2's and I also have a 4AGE manual.
Whats your email address - pm me
