I NEED Boost... Opinions puh-lease

[pimp my yaris]

That realy sucks, I thought U would have found something obvious. If it were me I would try switching the copper washers and retry it. Watch that thing like a hawk with plenty of light and see exactly where the oil starts to leak. When you thread the bolt into the turbo without the line and washers, does it go easily? Or does it bind up? Mabe the thread pitch is wrong on the bolt. Thread pitch is the number of threads per. mm or inch. Mabe the bolt is stoping before the washers get tight. I allready ran into this problem with a oil line kit for my turbo. Report back

[Focus_Sh1ft]

Yeah the washers are only very slightly chipped on the outer edge from where I was using a chisel, so no big deal. I honestly think they needed to be tighter. The way I had it earlier was such that the banjo fitting was still able to rotate with some force applied. I took the turbocharger apart so I could more readily get a wrench around the banjo bolt and tightened it a turn or two more.

The return flange is.. eh. I couldn't tell if there was a problem, mainly because I don't know what to look for. I'll be replacing the paper gasket, and using silicone on the bolts. I'll also start off by tightening it a little less...

The nice thing is, since everything is now installed, I can just put the turbo assembly on the engine block and attach the feed and return lines, then crank the engine. This will make it MUCH easier to spot any and all leaks.

Oh yeah, forgot to mention. The return line runs very close to the axle. I was looking at it earlier and it sheared some of the steel braided line. The inner liner is untouched and appears to not be leaking. Since it's the return line, I'll be leaving it for now and designing a bracket to keep it AWAY from the axle.

Sounds like your getting it under control. I would put some silicone on that return line gasket too. As long as their is coolant going through the turbo it should staw cool enough to work. Make sure the gasket surfaces are clean and smooth. Free of jb weld and chisel marks. Good luck and lets see a video!

Update: Turbocharger is back in and I just started the car. I'm not really sure what to think now.

There appears to be a small amount of oil coming from the return elbow on the pan - that's an easy fix. However, I noticed there was a drop of oil on the downpipe flange and where the downpipe connects to the exhaust... How could that have got there? My huge concern now is that for some reason, oil is finding it's way into the exhaust... Because upon starting the engine, I had a ton of white smoke that has yet to dissipate. It's in the engine bay AND coming out of the exhaust. Granted, I did just wrap the downpipe and turbo with exhaust wrap, but why would it be coming out the exhaust as well? Thoughts please

Edit: Just read this usually means the seals are shot... Please tell me this isn't true... HOW could it be true?

Did you end up repriming the turbo? how long were you running it for.

[Focus_Sh1ft]

Yeah I reprimed it the same amount as before. I let the engine run for about 5-10 minutes. I also want to point out there is no obvious oil burning smell, and the smoke DOES NOT have a bluish tint to it.

[Nexus1155]

Hmmmm, if the seals are blown they're blown. its only about a $30 fix but still shitty to do. Otherwise try to run it some more to see if it still smokes alot. If it isn't grinding or making wooo wooo noises, the turbo should still be good just the seals may be bad if the problem persists.

[Focus_Sh1ft]

Yeah no noises or anything... I guess I have no choice but to take it out... AGAIN.

I've read white is usually coolant though. I don't know what to think

Ah something else I just remembered - the radiator fan kicked on to full speed within 5 minutes of idle. I think this may be coolant and oil related. GREAT.

[pimp my yaris]

Engine burning coolant will be white smoke and smell like rotten eggs at the tail pipe. Realy foul. Hope your head gasket is ok. A bad head gasket or cracked head could be another cause for oil or coolant in the exhaust. Did you hear any engine pinging "detonation"? This thread is starting to make me nervious about my own project. Say it aint so Jerzy.

[Focus_Sh1ft]

Haha you're nervous? Imagine how I feel.

I highly doubt there are any issues with the head gasket. I know when I pulled the coolant lines to get the turbo out, I leaked ALOT of coolant because I didn't even realize it was slowly leaking for a few hours. Maybe some found its way into the charge piping? There's also a crap ton of oil residue left from when I was driving around with an oil leak.

I don't really know how to go about this. I think I'll check all my coolant lines, make sure the oil return isn't plugged at all, then off comes the turbo again. This kinda sucks

[Focus_Sh1ft]

Ok figured it out most likely. The paper gasket I used had flaps around the hole that actually blocked the oil's return for the most part. Currently trying to figure out how to cut those out, but I'm still worried the pressure build up may have blown the seal in the turbo? Guess I won't know until I lessen the restriction on the return.

Uh, on the positive side, the previous leaks I had are definitely dealt with at this point. I'll be more happy about that when I know for a fact that I don't have to rip the turbo out, pull it apart, and replace the seal.

Just wondering, have U installed the 1zz injectors yet. Also have U made any adjustments with the FIC

1ZZ injectors (and tb) are in. No adjustments to the FIC yet.

Here's where I stand now:

I unplugged the return, primed the turbo, fired up the car. Within a minute it stopped the white smoke, so that appears to be solved.

However, I was about to take the car out and now have a new problem. I tore out of my neighborhood and blew a ton of white smoke out the exhaust. It appeared to stop about a minute later, but then the oil idiot light came on? Came home, popped the hood, and nearly passed out by how much white smoke came out from under the hood. I'm 100% sure the smell is coolant burning... so... interesting... lol. I definitely hear some sort of bubbling noise happening around the engine block as well. Bubbling + burning = boiling? But why coolant, WHY?

I'll be checking all the coolant lines and blah blah blah. Anyone feel free to throw me some ideas. I also have a CEL again, and was about to go to advance auto to check it out but... not now.

[pimp my yaris]

Well I would say you need to start thinking about the head gasket or cracked cyl. head or possibly a massive coolant leak under the hood. The bubling sound was the engine overheating. I use a funel that attaches and seals directly to the radiator neck. After I have filled the coolant and blead all air out of the cooling system, I check for air bubles coming up from the radiator. If the bubles never stop. Their is a good chance of a blown head gasket or cracked head.
Clean the engine compartment with a hose and fill the engine back up with a 50/50 coolant, water mix. And first check for under hood leaks. It sounds like it overheated bad and possibly blew the coolant out of the resivoir bottle.

[pimp my yaris]

Its also possible that when U installed the turbo coolant lines, U may have created a large air pocket in the cyl. head. This would cause some bad over heating as well. When filling coolant U must keep engine runing long enogh for thermostat to open so coolant will flow through the cyl. head and push air pockets to the radiator filler neck. This will take about a half hour. During this time U must monitor engine temp. and make sure U dont over heat. If your fan has turned on and off a couple off times this will be long enough. Dont rev. your engine during this time. And make sure You keep the radiator full.
Sorry for long explanation. Hope this is helpfull.
Good luck in this mission as U have allready accepted it.

Haha you're making me nervous man. But...

I checked the coolant lines on the turbo and (thankfully) they're leaking. They only seem to leak while the car is in drive though, because during idle there is no smoke. If the engine was overheating, wouldn't it throw the engine hot light? I wish I knew what this CEL was...

I'm still worried about what you're saying though. The smoke does seem to be isolated to behind the engine block, and the exhaust. I'll work on the turbo coolant leak and hopefully all will be resolved.

cdydjded, are you saying it HAS to be this toyota brand coolant? I was using something else, and at this point most of the OEM coolant has leaked out or evaporated.

I'm also still confused about the oil idiot light. What would cause it to come on if the oil level is adequate?

Also if it's of any importance... The car drives absolutely fine currently.

As for the coolant lines, if you can stop the leak, dont use them until all other issues are resolve. It will be 1 less problem you have for now....

Honestly, I believe this is what I'm down to regarding issues. Oil is finally resolved, and after fooling around with the t-clamps on my coolant lines it appeared that there was definitely less smoke. I'm thinking the bubbling is simply the coolant burning on the turbo. However, the fact that the radiator fan jumps to full power within a couple minutes during idle (I don't think this ever happened before I put this thing in) makes me nervous. cdydjded, I'd greatly appreciate it if you could get me the specs on the coolant. I think I'd prefer to swap it with the definite proper stuff so I know it's not an issue.

[Focus_Sh1ft]

What's the brand name, can't tell. Think I could find it at walmart?

I have no idea what the hell I'm using lol. It's like lemon-lime yellow and I found it in an Arizona tea bottle. Probably wasn't the best idea in retrospect
