STARTED HER UP!
after cranking her for a bit to get the oil moving, i turned and key and she came alive instantly...not even hesitation or stumbling. purrs like a kitten...no leaks (water, oil or otherwise)!
d/pipe isnt connected yet so its kinda noisy...but it was cool seeing little bursts of water flowing out and then system becoming super clean with respect to emissions!
pics and tune updates tomorrow!
spoke too soon...! ran into a myriad of problems over the weekend. will try to be as concise as possible:
1. we carried the car to the muffler shop, did the downpipe re angling, all the while no leaks..things looked fine. hit the highway to visit my tuner and decided to do a lil WOT pulls...NO BOOST! i got a lil concerned and called the tuner...he suggested that wastegate had some issues. sure enuff when we got there, the rod is apparently too slack - i didnt kno the difference. so another thing to note on a evo 3 swap is the vary the bolt up of the wastegate (longer bolts/washers) in order to get things right.
we fired up, took for a spin and got a nice 9-10psi range. we put this to be a good base and dropped on a mbc in order to get 15. we now have 15 and the system boosts well (18 felt better tho!)
so this is
solved..just for info purposes!
2. anyways...heading down the highway to get some 3rd gear wot pulls for tuning, we started to smell heavy oil burning scent and pulled over. sure enuff, there is oil dripping from under the turbo area. we carry it back to the yard to see the sump, the downpipe, the return line and generally anywhere under the turbo very very wet with oil. we tried to rev whilst car was jacked to see source, but we cant. so i have to clean off the bottom and carry it for a spin and determine the source.
3.
a thing i'd like clarified is how do u get that damned oil return line on the turbo and sump properly? i tried it last week when puttin it up with the turbo end bolted in and the manifold just resting on the head (no boltd up). i struggled with it and managed to catch the bolts up but wasnt satisfied with my efforts. i have suspected this area as well so did it over today..it was even HARDER with the turbo bolted in place up on top. why i have focused here is that nowhere above that point is wet with oil..only from that point go down and its particulary wet around that sump join area. so i got a buddy over and we fought and fought with it and sort of got it back together again.
but why in hell is it so hard? i had to push the flange end upward whilst he tried to quickly catch the bolts in. apparently these bolts runup at an angle to the flange? it was overall a pain and i hope we got it right this time...the wash up in #2 above will determine this for sure.
4. we are still smoking thru the exhaust. not as much as before, but its there. granted that i honestly did not clean up the hoses/intercooler from the last 2 smoking scenarios, i pulled them today to find - in horror - a puddle of oil here, puddle there and the hoses very wet inside. the puddles were predominantly at the bottom of the hot-side pipe i have that turns into the intercooler, the intercooler itself had lots of gunk inside and generally the whole system. even the compressor side of the turbo has oil (alot) resting in it.
sorry for being so lengthy but i am at my wits end. ive tried everything so far and nothing seems to be specifically solving my issues.
ive got 160 compression across the board (give or take 1-2psi)
no other smoking - off boost, start up, etc.
a relatively new turbo (less than 17k on it)
had 3 others do the same thing
a healthy performing engine otherwise
so kinda all out of pinpoint areas. we are re-cleaning the system a bit to ensure that this isnt old oil circulating thru the system. my tuner also like me didnt like the 110-115 WOT oil psi we were seeing. its just too high for our liking and the sad thing is, this was NEVER so high. usually sat at 90-100psi tops on hot day, 20w50 oil etc....couple months later, same oil, same temps, and we're geting almost 10-20psi more?
so...any advice...at all..will be appreciated..im just lookin at this car and hating it now! kinda makes me wanna pack it all up! but i guess im a sucker for punishment

it's interesting tho that there was a distinct difference in the water bung positioning. i guess i should have factored in the compressor housing sizing and its effect on the line-up. ah well, u live and u learn (and u post it up)!
the hours i worked on the car were a bit unreasonable (9pm-12am). but the constant bending, lifting the turbo and manifold on and off, etc...really takes a toll!
