Me thinks turbo go bye bye

[Neosaber]

Hi all, just asking for people's opinions.....

The car has lost top end power like a mofo, feels like its not even going anywhere after like 4500-5000rpm.

There is a little oil in the intake manifold soemhow and its leaking out into the engine bay....i have taken off the intercooler piping to find a little oil inside there too....iam seriously clueless what the go is......i take off the blow off value...and there's a little oil in there....i take off the manafold....there's a little oil in the throttle body.....

oil pressure is fine, i check the oil 3 times a day and its going fine....just losing it into the bay/intake.....

have been told by a few people its called 'blow by' and could be the rings.....one other mate reckons it doesnt have all the symptoms of fried rings and its the turbo which is rooted......

i might as well mention i have had the stock s1 r33 gts-t turbo at 15 psi a couple of times for a few drags.....my bad

any of you smarties on here have any ideas?

Are you still making the same boost through the rev range

Are you still making the same boost through the  rev range

the boost gauge tells me i am but it has a bit of a splutter and it sure as hell doesnt feel like 10psi used to.....even a commodore cold prob beat me now....

after a little while when i'd give it full stick on full boost it would feel like its going nowhere. I little extra black exhuast fairy dust on my back bumper too.

Its booked into gavin woods workshop here tomorrow so hopefuly its nothing really major....i dont mind if its the turbo, good excuse to upgrade.....i just want to know how its leaking oil into the intake pipes/manifold.

a small amount of oil in the pipes/intake is normal. As long as its just a bit and not pouring out then its not the problem..

Could the fuel pump have died? Just guessing here but it may not be able to flow sufficient fuel over the 4500rpm range?

I had a 180SX that did the same thing and turned out the pump was the problem.

Highly unlikely to be the the turbo if it is still generating boost.

Probally a vacuum leak from cracked hose, loose clamp etc etc.

My best bet is a blocked PCV valve. Are we taking any bids?

[SECURITY]

my car does that too.. and im 100% sure its my fuel pump.. im putting in a walbro as soon as i can afford it.

[Neosaber]

turbo still def generating boost......how much for a half decent fuel pump...and is this something i can install myself

the car feels so gutless on boost

[Neosaber]

Had a few people look at the car, would a busted seal on the turbo cause a nice amount of oil to run thru the manifold and intercooler piping? Also the spool sounds weak as hell....

This blocked pcv problem a few of you have mentioned, is it an easy fix?

Do a search for posts about walbro by predator. The sock on his walbro dissolved within 6 months.
