Turbo Service

[Le0n]

Hi, I've purchased a Surf with a 2.4 turbo motor. Happy about that

Could some one tell me what a minor service on the turbo is and what it entails.

Thanks.

It would not involve pulling it apart as that would mean new seals throughout, they do not seal properly once they have been apart!

I have never heard of a minor service (which does not mean it does not exist) but I would suspect a mechanic might be borrowing your arsehole! So look into it

Realigned contact pins, flushed sedimentary waste, and cleaned and exfoliated the housings! (i used to help make up things to put on a service) I wouldnt used exfoliated but, thats poetic licence!

I dunno rob I've pulled apart plenty of turbos and put them together again and they seal fine. BUT I've also never heard of a 'minor turbo service' - if you want to give it a good flush just put a litre of kero or diesel in the oil and let it idle for half an hour, (don't drive it!), then drop the oil hot and let it drain for an hour or longer.

is it the 2L-T motor (cast rocker cover) or the 2L-TII (pressed steel rocker cover) or the 2L-TE (like 2L-TII with lots of wires hanging off the fuel pump)?

how many km on it? does it drive/boost ok? temperature ok? no leaks or bad whiney noises from the turbo? if so it doesn't need anything except regular oil changes.

Brian. I have heard about the kero before an oil change but never understood why, hence never done it. Does it thin the oil out and make for a cleaner and more thorough change?

Is there the potential to damage anything in the process?

Does it affect the fresh oil going in and should that replacement oil be changed sooner than the normal 5000kms?

Why should you not drive it after adding the diesel or kero? What is prefered, diesel or kero?

[slowhilux]

Ive had turbos rebuilt time and time again, never had any problems with them not sealing......

Minor service?? I'd say whoever told you it needed a "minor service" dunno what they are on about, you either rebuild a turbo, or you dont, simple as that

[ORSM45]

probably just his way of saying its on its way out

It's a 2L TE. Is there any one or any where I can get a service manual from.

The Daihatsu boys all got together and obtained one on CDROM. That was great.

watch the head on the 2lte they have a habbit of cracking
check out www.toyotasurf.asn.au they have a forum there with alot of tech on the surfs and part no.'s etc etc etc etc

Hi Spazbot,

Thanks for the info.

[dumbdunce]

the kero/diesel thins the oil and helps wash out any chunks of sludge that have built up anywhere. diesels have a habit of thickening their oil as the oil gets old so sometimes its hard to drain out all the oil for a change.

it's bad to drive with thinned oil as it does not provide adequate protection for bearing surfaces. the loads at idle are very low compared to the engine under load or at higher rpm.

there's no need to reduce the oil change interval if you let it drain well and replace the filter, in the tiny bit of kero that is left the short fractions will evaporate out fairly quickly.


not much to tune on the 2L-TE, best you can do it get it a big fat exhaust and keep the cooling system in top condition.

cheers

Kero is a very mild abrasive, we used to use it to finish lapping gas valves when I was a kid back in the 60's at the Sydney Gas Works. It's ok to use as a flush mixed with you old oil before it's changed.

I had a mate who changed his Honda Civic to synthetic oil and didn't do a flush. The cleaning action of the synthetic oil picked up a bit of sludge and clogged his oil pump. One stuffed Honda motor.

Maybe but I dought it some of the commercial flushing additives are a little safer to use.

[dumbdunce]

the commercial flushes probably are safer, but the times I've used them I'm popped the can and thought 'wow, smells just liek diesel'

plus I'm cheap :)
