Subject: Re: Break-in.......new engine (your opinion?)

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 !!
