**It was the seals.**

My CRX is currently in the shop for a turbo install. I recently talked to him after being out of town during the install and he said he got it all bolted it, started it up, and it filled the shop with smoke or oil. Im not clear on which it was, I was not able to talk with him long. He said he thought the turbo had a bad seal, which would be oil. However after talking to many people, I do not think thats the problem. For one, the turbo had no shaft play, spun freely, looked great, and was purchased from a reputable seller. Im wondering if there is either a problem with the return/feed, or maybe he forgot to let the car idle long enough to relearn everything (I did that once and it smoked like crazy and idled poorly, his exact description of the symptoms). We are going to meet up tommorrow to look things over together, so I will not know more until then, but I was hoping someone might know what could be wrong or what I should look for. Thanks.

After the install, your turbo shoudl smoke for quite a bit. It hass to burn off all the grease, oil and anything else that may have stick around your block and etc.

After a couple of days, all smoke shoudl be gone. Where does the smoke happen ? at idle ? at WOT ?

It happens only at idle, he never even drove it, just started it, and realized something was wrong. It was shipped in packing nuts, so there might be one in there also.

Where should it smoke from?

back exhaust.

Just let it idle for 30 minutes or so. And drive it around the parking lot.

Of course, after checking for leaks, oil pressure and etc.

We just have a downpipe right now, no exhaust. Which could also be why he thought the turbo was smoking itself, when it was only the dp.

If there is oil in the downpipe than your seals are blown.

MooreBoost

Ill check for that.

Check the charge pipes too if you end up driving it around the block or something.

I went to the shop the other day and took a look. There was a drop of oil off the tip of the DP, and then I stuck my finger up into the DP a couple inches and it was dirty, but not really oily. Im not sure how long ago he started it and had this problem, could have been days, so I guess the oil could have dried up. Ill just have to wait to talk to him again, and let you all know what else he finds.

MooreBoost

If the turbo is blown, I can purchase another 14b, or a 13g. Which would you suggest? And also, will my adapter plate, and oil lines work with a 13g? Thanks.

MooreBoost

Ok, we dont think its the turbo anymore. We checked the charge pipes and theyre clean. Then we checked the plugs and they had oil on them. Im going to run a compression test tommorrow but it shouldnt be anything internal, we had no problems before I brought it in. Any other ideas?

Up.

Check your valve seals, usually when you have high mileage motor. They tend to wear and it'll smoke.

Ok, I ran a compression test and the results are 210 210 215 198. When the car was in the shop the mechanic told me when he started it, it idled, but smoked and oil came out of the DP. I had it towed back to my house, and now the car cranks, but wont start, and no oil nor smoke comes out of the DP. Now remember, he's the one that told me the rings were bad, so he might just be full of ****, and the car could have never ran. The AFC settings are -40 for idle, and I tried -45 and -50 and that didnt help. When I crank the car the boost gauge does not go into vacuum, I figured it would. I can spin the turbo fine with my finger. Can anyone think of something that could be wrong, or something I should atleast check? Thanks.

MooreBoost

Up.

MooreBoost

Up, help please!

MooreBoost

Update, I just got it started, and its doing what the mechanic said. It started smoking the instant I started it, it was grey smoke, then after about 45 seconds of idling oil started to come from the DP. It did not drip from it but blew out instead. Any ideas?

MooreBoost

Ok, this is a pic of how much oil came out after probably a minute and thirty seconds of idling.



Here are two pics of the oil return.

Some of the guys at HMT think I have too much oil pressure, and thats causing problems with the seals. I did have to use a GSR oil cooler in order to get the oil feed adapter to work. I suppose that could have altered it. Someone has to have an idea...

Sounds to me like the turbo has some bad seals. Is the turbo rebuilt? Did you ever get it checked out or is it just straight from another car or a junkyard or something...

Back in my early days of boosting, I just grabbed a used turbo, checked for shaft play and threw it on thinking everything was fine. Turns out it was bad from the start and that sucker blew oil out the exhaust like a banshee. Strangely enough, there was NO oil in my charge pipes at all. Squeaky clean. Sounds to me like that's what is happening to you.

I had the same problem today, however I just had it rebuilt and got it in the mail bolted it on and wow. I have never seen oil fly out of my exghuast before. Bad times for sure. I am sending it back to PTE to get it fixed again.

your oil feed line is too big just by looking at the pic., and make sure that the return line off the turbo has no more than an 45 degree angel. I had the same problem and my feed line was too big and had an 90 degree off the turbo for the return line. Good Luck.

What size is your oil feed line ?

svmnredracr

if your asking me it was -6an feed to -10 return all you really need is -4an feed

I believe so too. Looks like a -6 at least. I was running a -4 on my old setup but then I got an oil restrictor. And now I am running the oil restrictor with the new -3 oil like that I got from http://Fast-turbo.com.

Greddy comes with a -6 oil feed line right???

Need to change the line and it should fix the problem if your turbo seals are still ok that is.

Most likely it was feeding so much oil that it was coming out of the Turbine side.

Keep your fingers crossed.
