Question [Help] Blouch turbo swap resulting in smoke

Hi guys, long time lurker first time poster.

Today i started my car for the first time after swapping the stock td04 on my 06 wrx with a Blouch td05h-18g (not the new XT model).

After about a minute there started to be whiteish smoke coming out from the turbo/downpipe area.

I turned the car off, started it again, and the white smoke appeared after pressing down the throttle a little. Im thinking it might have something to do with oil pressure.

First, the turbo didnt come with oil feed lines, and with all the research i've attempted to do, i didn't come across any information that suggested reusing stock lines would cause any damage.

So i've narrowed it down to 3 possible problems.

1/ Stock oil feed line pushes too much oil causing it to weep through seals and smoke

2/ All the chemicals (WD40 and such) i used in the install are burning - i am doubtful on this one because i used Isopropyl for the majority of lubrication

3/ Tubo is bad, seals are bad, oil is just leaking through.

Does anyone have any advice? I can't find any data sheets on the Blouch td05h-18g since it's a discontinued model, but i am hoping the problem lies with the oil feed line. I have also contacted blouch but am awaiting reply

Thanks all (Y)

Is there oil leaking from the oil drain/oil drain line from the turbo to the block?

Isopropyl alcohol is not a lubricant.

Sounds like you have an oil leak somewhere. Have you double-checked the oil feed line connections, the turbo oil drain hose to crankcase, all coolant lines?

What does this white smoke smell like?

You can always call Blouch and ask if they have any data sheets on the Blouch td05h-18g

after a turbo swap there is usually smoke which is normal since coolant, oil, and what not got all over the down pipe, up pipe. drive it and it should go about after it sits for a day. but if not then something else is going on. i would double check all the lines as well and make sure you use NEW cooper washers for the oil lines

Thanks for the advice guys, i'll pull of the intercooler and double check the drain line, but i couldnt not spot any leaks while priming the turbo with the intercooler off. Nothing underneath the car either.

The smoke doesnt really have a smell to it, probably because it's not thick enough.

Still awaiting on blouch to reply aswell

Technically no, but it doesnt leave a residue

Have you let it run for a while to see if it will burn off?

Not excessively, I wanted to ensure I'm not damaging anything first

Isopropyl Alcohol is a cleaner/disinfectant. If any residue is left behind, that is because whatever you were cleaning is still not completely gone.

What do you think Isopropyl Alcohol is used for?
Hospitals use it to disinfect surgical tools, for one.
Quote:
Isopropyl alcohol dissolves a wide range of non-polar compounds. It also evaporates quickly, leaves nearly zero oil traces, compared to ethanol, and is relatively non-toxic, compared to alternative solvents. Thus, it is used widely as a solvent and as a cleaning fluid, especially for dissolving oils.
But hey, if you want to use something like this for a lubricant, it's up to you

Im quite aware for what it's for, i just received some friendly advice to use over wd40 as wd40 will lease a residue. Would you say wd40 or similar would be the better choice? Isopropyl did do the job

WD-40 is a penetrant, not really a lubricant but it does leave a graphite residue behind after the carrier evaporates. Great for things like doors knobs, locks, etc.

What exactly are you trying to lubricate?

The lubricant used would depend on what is being lubricated
You have to be carful not to contaminate fluids w/lubricants

It was for the silicon inlet and other tubes.

On the topic of my turbo, I can't see any visible leaks and the oil drain line is dry and also does not seem to be leaking.

The smoke on the otherhand is directly related to revs and there for oil pressure, so i would say there is oil burning somewhere, might give the engine bay a hose down when it's cooled off

Also took the IC off and didnt see any oil in the piping.

I did drop alot of coolant through the engine, and i'd be confident that it was just coolant burning IF the smoke and revs didnt relate

If you are just trying to make installing the silicon hoses, etc. easier, you don't need a lubricant, per se.

A little water, or soapy water works wonders and doesn't hurt anything.

If the oil drain line from the turbo to the block is dry, and the block around the area is dry, then it's not from there.

If the oil feed lines are dry where they connect to the turbo are dry, and the areas on the turbo are dry, then it's not from there.

Have you checked the valve cover gasket, exhaust header gasket, turbo gaskets, etc. for leaks?

Have you checked the valve cover breather hoses for leaks, especially on the turbo ( passenger ) side?

Thanks for the advice Samurai, i havn't had a chance to look at it due to uni/work but will double check all those points tomorrow

Still awaiting a reply from @blouchturbo to verify whether it is an oil feed line error, is there any way to tag on this forum?

I just replaced mine. I had bad seals, and was making more clouds then a diesel. How bad is the smoke? Quart of oil in your intercooler? Lol
