Well... started stripping down the turbo's and piping AGAIN today... and noticed a fair bit of coolant in the pipe that connects on to the front turbo (outlet side of compressor wheel)

Somehow I dont think that is meant to happen.

Giving up on stock turbos.

I was hoping to get a decent replacement one to just get me by while I saved up... but after buying 3 sets and having every single one of them with a problem of one sort or another.

Guess its to be expected with 15yo+ turbos... but seriously, I'm already over it... time to quit wasting my time with the crappy stock jobs I think :-)

i just went a single to4b and its good. i will be selling my stockies and aftermarket dump pipe. not that you want another set but its seriously not that expensive to go single, i dont no what everyone is on about. if you can build your own dump pipes and cooler pipes its way cheaper than twin hks turbos.

I'm looking to go single now as well Dylan. Twins are just too much of a dick around... Means this car is going to be off the road for a fair amount of time while I save up for it.

So so sick of driving a gutless little automatic carby fed Gemini as a daily... Depressing at best

Unfortunately I have no welding skill and extremely limited fabrication skills... Would love to learn though. Regret not taking metalwork class in high school and doing woodwork instead!

Tim, may i ask , are you sure your not having something going wrong with the actual install ?

To have the same issue with 3 sets of turbos points to an installation problem that may be causing the issues with the turbos ?

I cannot work out why your getting coolant in the comp side of the housings ?

Daniel, I havent installed all 3 sets... not by any means (my frustration would be tenfold if it were).

First set I bought from a friend, mentioned needing some in passing conversation... got told he had some.. paid the cash, and didnt really look at them for a few weeks. The front one was seized (which I was aware of).. the rear one, which I thought was ok ended up leaking oil past the exhaust wheel. He has agreed to give me my cash back on those.

Second set was from another friend on here. First one leaked oil past the exhaust wheel, so didnt bother with that.. second one leaked oil past the compressor.. and whilst I wasnt overjoyed with it, it was the one I ended up using.

Final set was the ones I got ripped off from Trent Toovey, which you may have read bout.

Anyways, with the one out of the 6 that was worth using, I put on. Everything bolted back up the same way it came off... and I'd had it running... it was overheating and blowing a fair bit of smoke on the run too (around the block twice).

I also had a exhaust leak up the front somewhere... so I decided to strip it down again today with the intention of re-doing it all properly with new gaskets if needs be.

And thats when the discovery of coolant in the piping was made.

Needless to say, tools got dropped and and vehicle got walked away from.

i dont get how coolant is getting into the housing as its a complete serperate housing to the innards, unless the centre housing has cracked allowing coolant into the housing?

Otherwise there is literally no way coolant can get in there

Its got me baffled as well.

I'm going to continue to strip the lot down perhaps next weekend... in the meantime, I will also take the cam covers off and have a look there as well

(thinking perhaps if head gasket were gone, coolant could be coming through the breather from the cam cover back into the pipes somehow?... maybe?)

Under the oil cap seems fine... but it may be best to open it up and exhaust all possibilities.

Is it worth mentioning that the turbo on the front, was originally a rear turbo that had the housing rotated to be used as a front?

Makes no difference Tim. The only way coolant can get in there is either the housing is cracked internally, or as you were taking it apart, some coolant leaked in there. Don't worry mate, I will give you your $150 back, just take it out of the FMIC you are paying off.

Let me know when you get to installing the turbo mate, I have a friend who is good and cheap who can fab up your dump and intake pipe when you require it. Probably need a place to do the compressor housing to FMIC pipe though, as that requires a tig welder on aluminium.

Justin, I want to exhaust all options and find the source of the problem rather than just immediately blame the turbo without knowing for certain. I appreciate the gesture, thank you :-) however I would not feel too comfortable with the possibility that you are refunding me for something which might turn out not to have anything wrong with it. I wouldnt want it done to me, so I wont go doing that to you... if it turns out it that it definitely is the turbo, then we will cross that bridge when we come to it :-)

Its ok, I just need to muster some more patience and get back into it again. Find out how the hell this has happened.. and deal with it.

The more I think about it, the more I am leaning towards maybe the head gasket, because, like you have all said, unless the turbo casting is cracked, its not really possible.

Michael, thanks again mate. I'm really having to look at finances at the moment to get this happening. I cant bring the vehicle down unless I get on the back of a truck... I've got $400 available right now.. a bonus from work probably coming in this week... and taxation being lodged in a fortnight.

I could give a deposit, but the rest will just be a waiting game which I'm not sure how long it will take.. I'd rather work what kind of timeframe to expect first before diving head in and leaving you in the lurch for god knows how long.

If it looks like it might take too long, I may have to see what other options I can look into.

Leave it with me mate, I'm interested... just have to do the sums and see what I can get from where to make it all happen :-)

Yep only way water will get into inlet side would be split in turbo housing. Exhaust side could be anything.

sounds like your not having much luck with it. Michaels turbo kit is looking good for 3k. also then you will only have 1 turbo to fail, not 2.

Yet to check exhaust side, I only removed the induction pipes from the front turbo before the eyebrows became one with the hairline.

What is the possibility of the other idea? - being head gasket problem allowing coolant to escape into the intake piping via the breather in the cam covers?

Is that something in the realm of possibility?

Trying to brainstorm and consider any and all possible options here.

was your radiator chewing through coolant?

also by the time it came out the breather it would no longer look like coolant. It would be a milky sludge.

Are you sure you didnt just spill some in there without noticing? im pretty sure its the only logical explanation, apart from cracked turbo core. (never heard of this) but possible if turbos came off crashed car


And if coolant did get in there, it would dry up pretty quick with the heat and air flowing through the pipes. And if it didnt it would eventually get in the engine causing compression lock.

The radiator was drained dry at the time of the turbos all being initially removed.

After everything was bolted back up, I then put in fresh coolant and went from there. So there's no way I could have spilled any coolant inside.

The coolant was still that distinctive lime cordial green... so that eliminates the head by the sounds of it.

I am guessing the turbo has a cracked housing then, nothing else makes sense....

We will see Justin :-)

I will continue stripping it down this weekend.

And I will make extra care to do it slowly and meticulously and try and see if there is any other explanation for it (I sure cant think of any however).

Oh, and Christian, once the vehicle was running again, yes it was chewing through coolant (forgot to address that enquiry)

id definately say its the turbo core then mate, cracked head will mean your oil will be a milky brown sludge.

And i would highly doubt its t hat, as you would have drivability problems, rough idle etc.

So id say the only way the coolant could get in there, is through the core, or it got spilled into there.

Once you get the turbo off, remove the compressor snail (just a snap ring on the back im pretty sure)

Fill the lines etc with water then seal 1 of the pipes, get a airgun and blow into the other 1 at low pressure, if its cracked you will see water escaping somewhere behind the impellor

BTW got the springs mate, installed and lookin good :-)

Thanks Dylan... appreciate the thought :-)

Looking at that I am thinking one thing though... how long will it last?... and will I be throwing good money after bad by going down the cheap and easy path?

The mindset I am in tells me to spend the extra now and not have to spend it again, and whilst it's a harder option financially at the moment, is a smarter one I think.

Ultimately, this is what I have to be prepared to accept when it comes to owning one of these vehicles... you've got to be prepared to spend the money on it I guess

And Scott.. thanks for the suggestion... I'll look into it :-) Glad to read you got your springs and are happy
