A few comments - and one question - on this First I´d say I´ve never had a new WBX, my experiences are with I4 engines - hence the question....

When I started the Volvo I4 up for the first time I let the starter turn the engine for a couple of seconds before the coil was connected in order to start building a little oil pressure even though everything had been soaked with oil during assembly. I had the engine running at 1500 rpm for a couple of minuits while listening for odd noices under the bonnet then a little coolingperiod. Repeted this 4 - 5 times. Took a 20 minuit ride at 2-3000 rpm, letting the revs go up and down a bit . Then a loooong drive, about 250 miles with a 1 hour break about halfway. At the end of the drive I could feel the engine "loosen up" and occationally took the revvs up to 4-5000 rpm. The next morning I changed oil and filter, RE TORQUED the head bolts - never seen anything about this in the WBX, is it not neccesary there ???- changed plugs and set the timing again . . After that, it was used and maintained the normal way with oil and filterchanges every 10000 miles but for an additional oil and filter change after 500 miles too . I used 20W50 good quality mineral oil but have changed to syn. later since the engine was buildt with highpreformance cam, head and bigbore pistons ( up from 2.0 to 2.4 litres) It has dual carbs, would easily revv 7.500 rpm and is still running good today after 150 000 miles

I found a good investment in a magnetic drainplug, caught lots of metal there that probably would have clogged the oilcooler othervice !!
