Results of the Compression Test
 

well i did the compression test today to try to diagnois any problems that may have developed since the trubo install.

recently the idle is a rougher, and there is a trace of white smoke coming out of the dipstick

so me and my buddy did it today and this is the results

cylinder result
1 165
2 160
3 165
4 160
5 165
6 155
7 45
8 160


as you can see cylinder 7 is all messed up :cry:

we poured a little oil into the spark plug hole and it went up from 45 to 65. so from that we concluded that it was a piston ring.\


what do you guys think


and what should i do now. rering the piston, get lower compression pistons, stay with stock pistons or roll my car off a cliff :cry:

if ur inthere then low comp pistons

forged internals so you can run more boost

so does anyone want to forge the internals for me :wink:
i was already thinking of the lower compression pistons, but i don't have the funds to forge the internals. remember, i don't work :cry:

my aim is blacktoprecs if ya want help, or email me

That sux man, good luck getting her back up and running soon!

cool, i'll email you later cause now i'm in class. where are you located and how long do you think it'll take. there's soo much crap underneath the hood :cry:

damn man that really sucks. Good luck!

:( Sorry mang.

May I second the assistance of 9secfirebird.... he knows his stuff.

and he has cool t-shirts

but he's black!

RJ that really sucks man... its funny how whenever people blow up from Forced induction its always cyl #7

Re: Results of the Compression Test
 

hmmm, those seem terribly high. i say lower the compression down until they all match #7. less cyl pressure means less strain on connecting rods, pistons, and the crank :P

sorry to hear about the trouble with the motor. sounds like a good excuse for a big inch LSx from TTP with a healthy cam and head combination :)

Welcome to the world of forced induction Gen 3's. I broke number 7 piston also..... :evil:

is this a common thing with FI LSx motors?
are the pistons burned or are the rings just eaten up?
