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 )

damn that sucks hopefully everything gets fixed and your boostn again soon but when you do get boostn again dont leave your pcv valve attached to the intake manifold your letting boost into the engine and are you using an oil pressure reducer?

i took the breather out and left the pcv on due to the one way valve in there..and i was using a reducer when i first installed everything but broke it a lil while later and just ran straight 3an hose. if i could find another reducer i would use it but I will not be buying anything from atpturbo again.
