Hey guys,

2002 V70 II 2.0T 5 cylinder, 180 hp. When I bought it, the engine was wet with oil in several places. I replaced the PCV box and a defective camshaft oil seal that had slipped out. The PCV seems to be OK when idling. Under full load with boost pressure, the second oil seal on the camshafts came out – boost pressure from the intake manifold into the crankcase?

Other problems: There is a smell of gasoline in the interior from time to time while driving. It comes from the ventilation system/outside. I suspect it is the tank ventilation. Is there a connection with the first problem? I also have wave-like acceleration at around 3500 rpm and very little torque at low revs.

Maybe someone has some tips for me.

Cheers, Alex

Fuel leak is typical from the top of the fuel pump housing, fixed mine with epoxy putty 8 years ago.

Crankcase should be under vacuum during boost.
Any codes ?
Glove test ?
You might want to test the turbo control solenoid, it should open and close when voltage is applied.
See youtube videos to test it.
