OK i just happen to purchase an 88 gxl na, for 500! good buy right?
well i cheacked my oil level and it was really low, i have a leak somehwhere, most likely my oil lines, for they're are drenched in oil and grease.... i wanted to pin point exactly which line was busted( or maybe the pedistal ids that was the case) , but as i gave it gas past 3800 when the aux ports should open up i noticed a bit of smoke seeping from the header/ aux port area not much but still noticable....

any one had this problem b4?

you have four plastic Oil lines that run off the OMP and go to individual Injectors on the Engine.
You are going to have to Find out which one is Broken.They Run from the OMP and Under the Manifold,onto the Keg(two of them,the other two are on the Lower intake).
I am "guessing" that one of those lines is broken and Oil is running off there and onto your Exhaust manifold.
you won't really know without pulling the Top of the engine to see,or Pulling at the Oil lines,Which MAY snap when you pull at them.(so the best is to take the Upper Intake off and you can see the Oil injectors and lines).,.keep us Posted.

i checked them out today and they opened up normally after 4k rpm, and no smoke i wonder why? i think i must have over revved it too much cuz when i revved it i did from the throttle body, so i must have gone in the red and it did that, when i had someone give it gas from the inside it didnt smoke...

They should be fully open somewhere around 4000-4200 rpms i believe... have you modified the exhaust at all? s4's aux ports open off of back pressure from the exhaust, if you've modified it at all there wouldnt be as much back pressure and they wouldnt open as fully.

I thought the car needed to be under load for the s4 aux ports to function, hence the famous grease test? Idk, could be wrong. I'd still check the omp lines though.

yeAH they open just a tad bit, im thinking its gonna be the omp lines. im premixing as a precaution.

if you are premixing
might as well disconnect the mop rod so it injects less oil so you have a less leak
