... Your statement gives me pause: "pretty unlikely" does not mean "impossible"... Which to me also means you may know of the conditions that need to happen internally to that TD04 to make it possible, however unlikely it is. Is this the case? If you do know how that might occur...

Coolant in oil Cylinder head and gasket (have to do both) Oil cooler (rare on RN 1999- engines) Cracked piston liner Cracked block Fooling with the turbo is a waste of time, statistically At 200k the cylinder head job will run 600-900 in parts get a copy of VIDA up and running and check the ETM sen...

Not too much on the diagnostic advice (brain isnt all there right now), but if you are thinking of throwing a different turbo on it then you might need to get it tuned by a professional, unless you want to put countless hours into learning ME7 tuning and mapping out your bin. You will need VIDA to ...

Sounds like it could be fun to fix up! Keep in mind 99 is something of a mixed year and has quirks, it's the first year of ME7 engi...

Ok... I have the exact same turbo setup already. TD04 13T Mitsu... So a swap would need 0 remapping. Everything I've seen says otherwise about the head gasket... But since I can do the job either way, so I just may bite. I'll update after the bleed test I do Even if I did drop $1500 into it, which I...

I have a lead on a New England unicorn, but I think it needs open heart surgery to save it from going to the unicorn glue factory... It's a 1999 V70 XC AWD with the 2.5T. Around 200k, so 10k a year, and the dude said $500. It's also originally from Santa Cruz, CA, and despite being parked in his sid...

Was this your T5 that had a coolant/oil mix issue?

If so, what was the issue? How was it remedied?

Thanks!
