7AFE Budget Build!!!, ***not cable friendly*** Options

[southwest2118]

I know this should probably be in another section.
well my 7AFE in a corolla has been turbo'd since march of 2006 i believe. its my daily driver first i started at 5psi and worked my way to 12-15psi. haven't ran into any major problems with it. about 6 or so months ago i started getting smoke at the tail pipe after sitting at idle for a while. then as time progressed the problem got worse. Three months ago i did a compression test because blow by was pushing out excessive oil out the breather hose and found cyl 3 and 4 to be out of spec after putting a lil oil in it it shot up which meant rings were no good. The problem got worse, i had oil being pushed of nearly every seal that could leak. On 3-30-08 Sunday when i was in Houston it started smoking so badly it became undriveable, i left it there went back the next weekend 4-5-08 and stared tearing it down.

Damage found - on cyl 3 in between the first and second rings the piston broke(i guess you can say the ring spacer) i was able to take a peace of it out with my hands in one of the pics you can see this area missing. on cyl 4 there are two cracks in the same section as cyl 3 piston. visual inspection of rings shows no damage. visual inspection of cyl walls shows no damage.

(i know pic quality sucks )
