i have a 2002 volvo c70, i bought used with a bad turbo that came apart filling exhaust with oil. i had turbo replaced, then while driving the new turbo went bad then replaced that. motor was sludged, removed cleaned pan and changed oil to a synthetic and cleaned pan and screen but wasn't too bad with sludge the pick-up screen was not clogged. I had oil sending unit replaced. and manually tested and was told that was good. .
what would cause this to do that if pickup tube is clean? is this motor hopeless? engine is quiet, no taps or ticks.
also how long should it take to burn oil from exhaust it looks like a dump truck driving down the street.Volvo oil light comes after warmed up. new sending unit...?There is an oring kit for the pickup assembly. Usually these rings get hard and brittle. When that happens air get pulled in along with oil causing pressure issues.
You can get the kit at a deler, drop the pan and replace the o-rings on the pickup assembly.
Usually that will fix the light issue.Volvo oil light comes after warmed up. new sending unit...?Did you clean out the oil supply and drain lines that connect to the turbo. They can get clogged up, too. You don't mention that in your notes, so they may be something you should look into.Volvo oil light comes after warmed up. new sending unit...?check on the turbo hose.this is on top of the engine or side i may say.if this is loose.
