G22 turbo build

alright I finally found my oil leak in the piston problem...I need another oil ring (oil rail support) that goes behind the 3 oil rings that wiseco didn't packaged

[dbsharp]

huh?! more details please.

[Gtseviper]

Well to be more specific...in order to lower the compression with these pistons, wiseco had to move the pin location, which in turn projects into the location of the oil rings up to the expander ring. Under high compression in the oil pan area...the oil can seep in from behind the oil rings and come up pass the 1st and 2nd ring easy

exact pistons

notice how the pin hole location interjects into the oil ring area...an oil rail support ring goes behind before the 3 other oil rings

[Gtseviper]

I called wiseco today and I didn't have to do much before the guy said that he will send out 4 of the rail supports within 2 days

[dbsharp]

Dammit! I knew about these support rings, but I didn't notice that they didn't come with my pistons. why is wiseco not providing these? Thats BS.

[Gtseviper]

call them now...and they will send it to you for free. (these rings where suppose to be packaged with the pistons...some people got them others didn't)..do not start your engine if you haven't already

[dbsharp]

lol no I am waiting for the cash to buy the expensive oem bearings for my motor. King bearings are not good. The mains weren't even the right size (about .001" too thin). I should have the $$ by next week.

[Gtseviper]

problem not fixed...one the rings are gone they are gone...I have to get a complete set new rings

[dbsharp]

whats wrong with the ring?

[Gtseviper]

to much oil got pass the oil rings since I didn't have support rail and and now I have tons of oil on top of my pistons....grrr

[dbsharp]

I don't see how oil getting on top affects the ring itself. How long did the motor run?

[Gtseviper]

Ok..I want you to install your pistons oil rings without the support rail...then tell how loose the oil rings are in the seat...Now install it as is with out firm support...The oil rings will be ok for a sec until it beings to flop around in teh oil area without sealing correctly in position...Now you have to much oil bypassing the oil ring to the first and second rings that not suppose to handle that much oil at one time...now you have oil blow-by

anyways I just sent the pistons and rings back to wiseco for them to check it out for me..

[dbsharp]

I don't see how your top rings get damaged from this. I could see damage happing to the oil rings if you ran the motor much or at higher rpms without the support.

[Gtseviper]

ok...well I have oil everywhere on all the pistons..gunks of it...and I'm working on fixing it...I just sent the pistons and rings back to wiseco to check...because a sec more I would have been done with project..I"m just recheck my cylinder walls and lightly hone it

[dbsharp]

don't quit while your so close! When it gets to frustrating just take a little break from it.
