Compression Test

Well for those who have been exetremly helpful. I did a compression test. results are as follows
1 - 165/170
2 - 170
3 - 165/170
4 - 170

So but when i move the car at idle does not smoke, when i rev it just to check ( only did this once ) and when i say move i mean in and out of the garage so i can work on the hatch. anyways it still smokes. could this be caused by not enough oil or maybe oil not getting to turbo?

Help please.

Are you sure it is oil smoke?

Bad seals in the turbo CHRA could cause it to burn oil. Or if your turbo oil drain line and/or PCV were up to par, oil can back up in the CHRA.

Maybe you are running just ridiculously rich since, if I recall correctly, it is untuned. I hope you atleast have an A/F Ratio gauge....preferrably a wideband o2

i have a A/F gauge, i have wideband on the way. Maybe it is just reallly untuned. i mean turbo looks brand new.

your driving around a boosted car completely UN-TUNED?!!??? Your lucky your compression numbers were that high....an a/f gauge is only going to show you what it is not change or adjust accordingly....get something decent like hondata AND a wideband and go have someone tune it before you blow it up...because it will happen :roll:

compression numbers look ok. have you done a leakdown test? that will tell you more than the compression test will

Huh no, im not that freaking stupid!

Im in the middle of making sure the turbo's seal's are good, and making sure that the turbo is getting oil right now. I have a wideband setup and hondata on its way. then i am probally going to go get tuned.

Well i figured out what was going on, The turbo wasnt getting oil. Im not sure why thou. i primed it, so that there would be oil in the line. im in the process of fixing.

Not getting oil?

I'm curious to how that happens. Good oil is the life blood of a turbo........more so than the engine.

An engine will survive with oil pressure a little low. A turbo spins over 150k RPM's. It needs sufficient oil pressure (unless you got a Garrett GT ball bearing CHRA). It will die without oil.

True dual ball bearing turbo's don't need as much oil pressure. It will essentially flood them (in the simplest terms)

Since you escaped a problem....how about you DO NOT drive the car until you tune it. You may have dodged a bullet but I'm still questioning it. Low oil pressure in the turbo usually will not cause it to smoke. The only smoke that will cause is gonna be what kills your turbo when it starts burning shit up.

Fuck what everyone tells you. Tap the turbo oil feed as close to the oil pump, but after the oil filter as you can. Assuming it isn't a Garrett GT(R)or Garrett style dual ball bearing CHRA. They do not need near as much pressure to perform. Too much oil pressure on those can actually kill them

exactly...don't drive the car until it is tuned...and yea how can it smoke when it's not getting oil...smoking is generally due to too much oil going to the turbo or bad seals.

I don't think tuning is going to affect his turbo getting oil, he obviously has other problems.

But I don't think his turbo not getting oil is gonna produce hugh clouds of oil smoke. It is obviously coming from somewhere else....if it is even oil smoke

Driving it around untuned is what makes extra holes in blocks

I REPEAT> I DO NOT DRIVE THIS CAR. i took it out once weeks ok just because i had to much excitement and wanted to see if it would spool. THis car has been sitting since then. So please i know that the car can not be driving untuned. i have a wideband and hondata coming in so that i can get it tuned.
Now that i cleared that up.

When idle it does not smoke, it would only smoke when it would be revved. and how i know this is because every rare occasion i have to moved my em1 out of the garage to work on my ek9 i have to back the integra up. now i have my drive way situated that i dont have to move it.

And what i did is i pulled the line off the turbo, figured hmm i should get some sort of oil or somethign to maybe drip nothing. so i pulled the line. And hooked my blow gun up to see if i would get any splater on the ground when air moved threw. NOTTA. so i pulled where i have it tapped in at the oil pressure switch. i pulled that fitting off and seen only alil bit of oil but not enough to make me believe that there was oil pounding threw the line. So i dont know. I pulled the oil pan off so i can do some work to where i have it tapped in there. but i need to figure out when i put it all back together if it is or isnt getting oil. before i get it TUNED
