Johan's 850R

jagardh

I got it on eBay, seller is xaviar turbo. Kit came in Mitsubishi box and every little plastic bag is marked with part number and Mitsubishi so it seems authentic. I paid around 100$ including freight.

I did mark the turbine wheels up so it should be fine without balancing. Not 100% sure though as I haven't done it before.

I believe @clinton‌ did a similar rebuild recently

They do alright as long as it's marked in my experience.

Excellent news , i must do this in future as well.

Now its back in one piece again :)
Just need to wait until my new torque wrench arrives so i can tighten the last nut. It only requires 2nm.

This is why it had play in it. that ring is worn into the old part.

Vee_Que

Bit of a waste to buy a torque wrench for that. Just a small spanner and not much force to do it..

Luggage scale spanner and maths

I remember @jamesinc‌ said something like that and the result was the nut came loose and shit went mental. Nothing wrong with getting tools to do the job right. Tools are more of an investment than a cost. Good work there!

jamesinc

No, mine was a different issue. I lined the nut up with the wrong marking on the shaft and it spun loose. When I did it the second time, Nick's suggestion to use the luggage scale worked correctly.

IIRC the issue is it is annoying to get hold of a torque wrench that does such small values. You need a bicycle torque wrench, and who wants to spend $90 for one bolt?

I found one on eBay for 54$ and hopefully it's decent quality.

I think the setting for this one is 50 in-lbs / 5.6Nm.

jagardh

Hmm it says 2-14nm in the description. Maybe I have to find my luggage scale....

Today i put the turbo back in the car. changed oil and filter and filled it up with coolant.
It runs smooth but i still have pretty thick white smoke. it does not smell like coolant so i dont think it is head gasket.

anyone got an idea what it can be? Can it be oil residue in the intercooler and pipes? Vale stem seals?

egads (she/her)

Intercooler can fill up with quite a lot of oil over time maybe start with that?

jagardh

Thanks, will have look at that

jamesinc

The IC on 850s has a small drain hole in the bottom, so it shouldn't fill up

Valve seals? Seems a common white block issue.

jagardh

I have ordered a valve spring compressor and valve spring pliers to do the valve stem seals. Bought the parts from the US (around 250 AUD for all i needed). I called volvo in brisbane and they wanted 20$ per valve seal!!!, 100$ for chemical gasket plus some more money for valve cotters etc.

Hopefully this will make the smoke go away

Its worth double checking the PCV hoses are not blocked/crimped, if the new valve seals don't fix the white smoke you could also try changing the PCV hose (return to intake pipe) to 5'/8 inch hose, could be excessive blow by that that stock oem hoses are choking.

jagardh

@phonsa i did change the PCV (volvo OEM). Do you mean that this can still be the problem and that it might be fixed to change one of the original hoses?

You can get a complete head gasket kit from IPD. Permatex 51813 Anaerobic Gasket Maker

I found a cheap valve spring compressor and spark plug air thingy on fleabay
