Noob turbo question


falco

Recommended Posts

Hi!

I've got an SF5 Forester (1997), with a dead turbo. Least, that's my assumption. Everything works well - runs smoothly, boosts OK, etc. But, smokes all the time, with huge clouds when the turbo spools up. I'm assuming the oil seals have failed. So, the questions:

- What turbo would this have? VF20, TD04? It's all completely original, as far as I can tell.

- If it looks OK regarding no internal damage, OK shaft play etc, is it possible to replace the seals?

- Does anyone have a turbo floating around they'd like to sell?

Cheers,

Mike

To be clear a turbo seal in a td04 is quite literally a piston ring so it doesnt blow/fail. If oil is passing the seal it will be due to another issue that needs fixing. Oil feed, return, contamination or failed bearings etc. Whip it off and pull housings.

So - this would definitely by a TD04 then? When I get time I'll pull the shields etc. off it and see if it's marked, but I would expect that it'd be pretty predictable.

Also:

- Oil feed must be OK, or it wouldn't be dumping oil into the the housings?

- What can go wrong with the return? Just get blocked up by bad oil and crud? Or is there something complicated, e.g. pressure regulation valve that could be stuck?

- Bearings could certainly be bad. Car has done 174000km, who knows how hard it was driven.

A new ones like $100, if it were me I wouldn't bother rebuilding it, just chuck another on and cross fingers

That's what I figure. I'll check it's getting oil and the return is clear, and see if the shaft is flapping about first.

Where's best to buy a replacement?

what colour smoke? on / off throttle? hot / cold etc

It smokes a bit even at idle, but not much. Even light driving isn't too bad. But as soon as it boosts, it lays down a huge smoke screen, and keeps doing it for ages even if I take it easy. Hard to see the colour of the smoke, but it's dark.

Haven't had a chance to pull it apart yet, been working on a Legacy. Will do it ASAP.

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
