You bet it's an issue. The mann w917 never set the oil pressure light at startup except maybe a nanosecond. These blackies are no darn good. One other time I used an off-brand filter and also encountered the oil pressure light staying on at startup 4for 2-4 seconds. 2-4 seconds is too long for me.
The early white blocks had spin on filters that were vertical. So they didn't drain back. I didn't look at the mann catalog but maybe that is what they gave you? After all it read volvo in the listing.
Which part is a tight fit? I'm not familiar with the dimensions, but the W917 is a tight fit to the alternator on all my 240s (even with denso alt) to the point that i have to disconnect the battery to change oil.
Maybe your interference with with the downpipe due to the relocation arm.
