I've already removed the flapper valve from the intake air thermostat, the hose that sucks in hot air from the over the exhaust, and capped the hot air side off so all the intake air comes in from the front. Did that awhile ago when I noticed how high my intake temp was getting.oragex wrote: ↑27 Nov 2020, 12:38 The 2001 had problematic throttle body and also the transmission was fragile. I would not try replacing more than 1-2 liters then drive for a while. Check the link in my signature below for videos about 'intake air thermostat' and PCV test (very important). Sites like Fcpeuro.com sell good parts like Sachs, Lemforder, Bosch - but also poor brands like Febi, Proparts and others
ETM has been replaced with a used XeMODeX ETM, that was donated to me through the FDPP here.
PCV system has all been replaced, too, with Genuine Volvo parts. The lines in the block were already clean so I didn't need to clean them out or drop the oil pan. I got the parts for that from FCPEuro, and the Oetiker clamps, and tool, from https://www.belmetric.com/oetiker-ear-clamps-c-15_494/ which I've also used the clamps to seal up the lines for the power steering reservoir and pump too when I flushed and refilled it last week.
