I have no idea of the quality of the parts as I'm just starting this pursuit.

VTI - I intend to zero time it. New bearings, rings ...

Wife's super clean garage kept 04 v70 is needing an engine rebuild at 280k miles. She'd rather me refresh the drivetrain than get something newer.

I'm not seeing cam bearings in the rebuild kits so my question is how are the heads and cam dealt with during an overhaul.

I have past experience with ...

So I'll close this thread out with the oil leak resolved.
The exhaust hub had a lot of play and both front oil seals were bottomed out. So that was the leak.

What I accomplished this weekend:
- front and rear camshaft oil seals
- exhaust hub replaced
- intake hub reinstalled with new o-ring ...

Thanks.
Agree on my mighty vac not being sensitive enough.
Just read the excellent right up by cn90 on cam seal replacement. At 280k Miles I'm ordering the parts for front & rear seals, hubs and TB.

So the oil leak is getting worse. Appears to be coming from the front crankshaft seal and or Cam seals.
I put a vacuum gauge on the oil dipstick hole and there was no vacuum or pressure, idle to 3k rpm.
In addition recently got the code that says the EVAP vacuum pump behind the muffler needs to be ...

The driver's side spring seat has over 100k miles and is still good. The passenger side is about to get its third changeout in the same timeframe. Last repair used the xc90 heavier version. That was 35k miles ago.
Any suggestions on what else I can replace that would make the passenger side spring ...

I have successfully used a steel guitar string as a snake to clear the sunroof drains. I use the smaller ones on motorcycle carb port cleaning.
