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 )

as of right now 4-9-08 i'm waiting on the guy from the machine shop to come and pick up the head and block, do some measurements and see what i need to do. I'll keep this updated

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.

how many miles did it have ?
you were boosting up to 15psi on an auto ?

>
thats why you were blowing smoke then waaaaay too much oil pressure and i here ya on the atp turbo reducer i ordered mine from jgstools.com.....much better quality

>

around 180k ....the only problem i've had with the trans is the axles have too much play and start knocking.. i think in the past two years i've replaced both of them maybe 7 or 8 times ...i plan on doing something about this maybe 5 speed conversation in the future?

70psi is too much?

i'll check out that site.

haha yea 70 is waaaay too high

Well yesterday(4-25-08) i got my block and head back from the machine shop.
i think i'm getting better at talking pics with this $50 dollar camera



i couldn't resist the urge to paint it




allow me to reintroduce the 7A







in the pics it looks like i missed some areas










-




el cheapo ITM pistions

this is where the magic happens

the turbo came off of a volvo - anybody know if this is a standered 5 bolt down pipe flange?
so i can buy something like this http://i35.photobucket.com/albums/d198/bre..._flange_obx.jpg and go external wg?

looks like the same 5 bolt pattern call em up and see what they say

how much did the machine shop charge you for the work?

the rod caps have a "2" stamped on all four so i guess thats the size of bearings i'll use and plastigage


but for the main bearings what number is the dealer looking for? where do i find it? the only numbers i found were:

2232



and 22333 witch i guess makes more sense







>


it cost exactly $820 i'll post a list of everything they did and the charge when i get the receipt

well bro, you got to get a decent camera

are you doing any work/modifications to the head?

damn bro i got mt block bored, honed, and cleaned for $120

>








today i got the crank and rod bearings plastigaged ...tomorrow i'll start cleaning and start reassembly

hmm

any whats your eta on gettin this back on the road? looks like you;ve made some descent progress so far.

and how much hp was it puttin down at like 8-10 psi? i cant see anything good happening on a somewhat stock bottom & top ends runnin 15psi+

>

next weekend i hope its ready. i'm having some issues with ring gap - three are somewhat alright, one cyl is set up for full drag


it'll be alight
