Compresion woes

[TurboStutr]

Standard is 164, with a max variation between cylinders of 14psi...

1- 150
2- 140
3- 60!!! :sad:
4- 140

I wanted to get it running right and put it on the dyno before a rebuild...but that ain't gonna happen now.

Haha, that's what you get for owning a Mitsu. product, wait.....oh fuck.

So you ran 12's with a dying cylinder?

[pat94cobra]

sorry dude.

only 4 readings? Where's the rest? Oh wait... :)

Put some oil in the low cyl and see if the # goes up. If it does, its the rings. If it doesn't, it's a valve.

god i hope it's only a burn't valve.

Pretty much, I knew something was up when I popped the hood and saw the oil that was spewed out my valve cover breather and the dipstick tube after that run...whoops.

Hehe...And I'm probably gonna do the wet test tonight to narrow it down.

UPDATE: After a quick dry test the compression was up to 70 in the bad cylinder(right after a hard drive, with a good full charge on the battery)...then a capful of oil brought it up to 95. Yeah that's not good :sstony:
