another TD42 turbo oil feed question

[Mark2]

I'm in the process of fitting a 2nd hand turbo kit to my TD42. The donor engine used an oil cooler with a sandwich fitting under one of the oil filters. This has fittings which were used for the turbo oil feed and the oil cooler lines.

I'm ditching the oil cooler and the sandwich plate for the time being and want to take the turbo oil feed from another location closer to the turbo.

Searching previous posts, most people seem to take the oil feed from a fitting near the passenger engine mount. My question is, is this the same fitting used for the alternator feed - if so, I presume a T fitting is needed?
Or is there another fitting in the vicinity?

On a GQ there is a oil feed from memory in between the passengers engine mount i think its about an 6 or 8mm hex key thats the best one to feed a turbo its a feed direct from a oil gallery ..Cheers

Thanks - had a look this morning and found the hex plug.

Looks like the turbo might need rebuilding theres a fair bit of side play and it kind of binds up if you push the shaft sideways and try to turn it

Bummer mate, but better to work it out now than have it spitting bits of shite into your nice motor!

Spoke to a diesel place this morning - they reckon once its spinning and with a film of oil on the bearings it should basically self center and so should be right to put back on ?? I

some side movement is ok but end float is no good does it have any?

[love ke70]

a bush bearing turbo will always have a bit of movement, it aint fucked til its scrapin the housing coming on boost

[Mark2]

No end float at all, but you can make it scrape a little bit if you push sideways fairly firmly and turn it. It feels really smooth to turn.

thats because there is no oil pressure in the bearing.
i wouldnt be pushing too hard on your turbine...

at the end of the day, they usually give you plenty of notice before destroying themselves.

the only i had that didnt (i went through 5 turbos on my go fast car) launched the exhaust wheel into my muffler, stupid ceramic wheels...

if your really worried, take it to a turbo place, get it checked over, then fit it.

cheers, andrew

Well, I ended up putting the turbo one as it is/was. Took it for the first test drive tonight - its awesome! I've never had a turboed TD42 before so dont know what to compare it to, but the difference is amazing. Its possibly a little worse under about 1500 rpm but after that - wow! Speeding tickets are going to be a distinct possibility if I'm not careful.

The turbo is very quite so hopefully the play wasnt an issue.

if it was rubbing the housing, you would know about it, sounds like all is good

So Mark2, did you just pick up a second hand kit and bang it on? How many kms has your TD42 got on it? Can i ask how much you paid for the kit?

Its a bit complicated because the kit came with a parts vehicle - what I get for the left overs will determine what it owes me. Thats not much help to you....

The engine has 438,000 km on it. Compressions are good and all seems fine.
