i would go and get a oil restrictor valve for your feed line. honda engine put out about double the amount of oil pressure your turbo needs, so i'm guessing its that...

 

I put in the restrictor. I wasn't too sure where the best spot would have been. I hear from some that putting it off the block is good, and some say it's also good before the turbo so I went ahead and did it before the turbo.

After putting it on, I degreased the whole entire area, drove it around for about 30 minutes and still noticed some smoke. It wasn't AS much, but still some smoke. I checked my chargepipes once again and there was no sign of oil to be seen.. Not even at the compressor.

As I was taking apart my charge pipes, I noticed a kink in the oil return line. It was the same way that it was in the picture.. But the kink wasn't as visible until you actually squeeze the line.

It seems as if only 40% of the oil was going into the pan smoothly. It kinked right before the oil return flange on the pan.

I'll be replacing that return line tonight w/ a line not as soft and hopefully stronger and thicker.

Question: When I took the line off from the pan, oil poured out on a flat surface. Could this mean I put too much oil? I put in about 3.75 quarts or so and the dip stick showed full. So now I am a bit confused.

My oil return flange is actually at the very top.. But the hole of it is almost the size of a quarter...

Anyway, I believe it's the kink that's causing the smoke now.

 

Maybe it's just the way the picture was taken, but your turbo seems to be clocked at more than a 15 degree angle from straight up and down.

If this is the case, you should reclock to be as straight up and down as possible - this would definitely have something to do with your slight oil leak.

 

I believe it's just the picture. The turbo is clocked perfectly so that the feed line points up and the return points down.

I'm going to have to try to make a line that goes 45 degree towards the pan, and then start it from there..

 

That doesn't appear to be kinked from the angle you took the picture... but if there truly is a kink at that spot just before the pan (an underneath shot would show that better), then you probably need to redo the line (possibly take some length out of it) to eliminate that.

A 45 coming off the turbo and 45 into the pan might position it just right.

LOL.. exactly what I was thinking.

45 off the turbo and 45 into the pan would eliminate any sorts of kinks. I'm hoping to have one straight line about 3-4" long..

 

UPDATE

Well, I finally took apart the downpipe and no traces of oil whatsoever was found. EVERYTHING looked clean. I cleaned off the oil on the compressor and drove it around for a while. After rechecking charge pipes, intercooler, and DP once again, I sitll found no signs or traces of oil.

HOWEVER..

I looked around my headgasket and found some fresh oil there. I wipped it off, drove it around and came back and again, found some fresh oil. Not ALOT, but anyone can notice it. I checked my coolant and everything seems to be fine. no smoke coming out of the valve cover breather or anything..

BUT..

Now I think that my piston rings could be a HUGE possibility. While installing my turbo, I put on DSM injectors w/ a resistor box. First time starting it up, it had trouble starting. Once it started, it threw nothing but blue smoke and the only way to keep the motor alive was the give it full throttle and yet, it would only stay at about 700 RPMs with heavy vibrations.... AND throwing blue smoke. After that, I decided to use the stock injetors just to see if it would start. It did, and ran fine.. ( I ddin't boost more than 7psi)

So from all the facts that I've gathered, I came to the conclusion that the turbo is good, my return line is fine, an oil restrictor IS used and the only possibility now that I can think of is ...

-damaged piston rings

-leaky/blown headgasket, although it could just be both...

What do you guys think?

 

Lots of times, oil around the headgasket can simply be a valve cover gasket leaking down the side of the head ...

 

I'm guessing it's the piston rings then.. Because my temp seems to be A-OK... no signs of oil in the overflow tank or anything..

Looks like this one is gonna cost me a ******* grip just to get it back to running standards..

 

Well... it's still smoking... ?

from where?

 

All of it is smoking from the exhaust.

I had left the car in Nuetral (*sp?) and revved the motor up to 3k RPMs and held it there for about a minute. All that came out of the exhaust was blue smoke and tons of it.

yet again, the turbo seems perfectly fine. No signs of oil anywhere... Opened it up from the exhaust side and no signs of oil. NOWHERE to be found..

The motor is pretty old. 1st gen. B16A to be exact so I'm assuming the rings were already in bad shape.

I don't notice any stuttering while driving or any hesitaton nor overheating.

 

You won't necessarily see wet oil in the exhaust, it is burning up...

I say compression/leakdown if you are worried about the motor... but I still say find a friend with a spare t3 or t3/t4 hybrid and try it out.

 

I see.. I see.. hmm...

Cause I opened up the DP.. and I didn't see any moisture what so ever.. I'm THINKING about putting my stock exhaust manfold back on to see how the car will react..

But I think you're right.. A compression test sounds like a good idea. I picked one up yesterday but I haven't used it yet so we'll see..

 

I ran a compression test yesterday. Results were 200 all accross. I've narrowed it down the turbo seals...But is there a way to absolutely make sure??

btw.. the oil near the headgasket was leaking from my stripped valve cover bolt..

 

in my opinion conclusions are being jumped to too fast. your best bet is what size is your oil drain line? i read but forgot, it is recommended to use -3 feed (some use -4 and it is safe on bigger turbos) and -10 drain. which would be a line with like around 1/2" ID roughly? make sure your lines big enough, it does look big but just make sure, in my opinion you can't have too big of a drain line, only too big of a feed line. i would center this problem down to lines and lines only (the feed/drain) which many have said they feel is the problem here too. however, on my car i've fixed my lines and the seal continues to leak out of the same spot yours is. i don't think those seals self-repair after they're blown. i even went to 20w-50 and everything, nothing worked. gotta do a turbo rebuild

 

This is my new return line..



I'm sure the size is good enough. There are no longer any kinks and oil is only traveling downhill..

BTW.. Could doing a wet compression test effect the result of a bad piston ring?

 

pull your spark plugs and read them. If the rings/ringlands are bad, you'll see evidence of oil on the plugs. The plugs should be a nice dark tan color with no specs, or residue.
