150000 miles ka(got free from a memeber three years ago), replaced headgasket, reringed(ghetto way: just clean carbon take out old rings and put in new rings. clocked them according to FSM). New headgasket oem, arp head studs, new front main oil seal, guides and timing chain was fine(another place i cheaped out
). All was cleaned up and put back according to FSM, eyeballed main bearings and were retorqued. I know I know i know, i should have replaced the timing chain oil pump tensioner, but i didnt so blast away. The turbo is t25, full face front mount, z32 maf, apexi air filter, hks ssqv, koyo radiator and FAL fan setup. NRG adjustable FPR set at 35 psi i think, but was stock settings according to FSM, was done when i assembled everything together. Running 610cc injectors from a scooby, side feed, rom tune. Daughter board setup from emance(i know you guys dont like him, so please no comments about the tune sucks or hes a .....blah blah blah). the first tune he sent was on the richer side, so he sent me a retune after about three months, his mailing setup is not the best out there, Agreed.
Have been driving this first tune setup for a bout six, eight months, put prolly 8000 miles on it, no problems. Oil was synthetic valvoline 10w-30, filter was fram tg(my doubts go there too). have used mobil1, stp and what not. Boost is max t25 8 full psi...nice...
Installed the retuned chip in earlier this month, kept an eye on wideband and was not going leaner than 15 on cruising, on boost drops down to 11~11.5. Fuel mpgs were about 23mpg for three tankfuls. Never let the temps go above 210F, have to turn on fans manually, no controller. Sorry for the lengthy history, now comes the issues part.
Last night, while coming back from work, all highway about 32 miles to home. Started off, warmed up for 5 minutes, temps hit about 160F, drove out from parking lot, onto local streets. Didnt go into boost, maybe 2psi at most, got on the highway and started boosting, went about 3 to four miles. Was in fifth gear and doing about 70, started going into boost and went to about 90. then started to coast down to 65mph, had a pop from the exhaust on throttle tip in. Then noticed that i wasnt building speed any more, turbo was coming on instantly, but the car felt as if it was towing a semi. WTF? this is about 8 miles from work, dont have money to tow, so pulled over and saw oil on the valve cover. Oil pressure went down to 15 to 10 psi, oh oh... seems to me that the oil has either disappeared or oil pump is toast. Seems to be coming from the valve cover breather filter, i have noticed blowby on startups but never did anything about it nor did i check it again. started to drive it at 45 to 55, and costing mostly for another 10-15 miles, but after that it was getting worse so i pulled over to the side, checked oil and there was none. Called my brother, poured in oil but the battery was dead coz of the lights and hazard running, tried to jump it, motor was turning very slow. Said screw it, called the tow truck parked it home and went to work next day in the Audi(96 A6)(this car has issues of its own but thats another story.
Questions:
Where did the oil disappear?? Car does not smoke, only driver does.
Did i bust the ring lands? the missing burbling popping while driving tells me that.
Did the oil pump take a dump? no oil pressure... filter blocked.
None of the oil fittings, turbo feed , return line have any leaks on them.
Spun bearing? would that cause a no oil pressure scenario.
All inputs welcome, come in, let the smackdown begin!!
(how do i put that poll thingy mods?)
. number 1,2 plugs are fine, too lazy to remove strut bar to check number 3. 
Next: check compression.
