I hope you put two 1/8" pieces of tubing into the airbox so you can trickle 3-in-One oil onto the bronze bushings so the new motor doesn't lock-up and fry like the old one.

The main reason these motors fail is that the bronze oilite bushings run dry after a while with lots of cold humid air passing through the airbox. The short-comning of Volvo is that there's no provision for regular maintenance.

Simply sticking a small tube into the bearing area and dripping light oil onto them once a year will make them last nearly forever, and if your motor starts squealing, you can prevent failure by doing the maintenance.

My 240 started the squeal at 225k miles (7 yrs ago) and still noise free and running fine at 350k mi, but the ATF/3-in-one goes in once a year.
I did that job once about 25 yrs ago, and will never do it again.
