I, too, just finished an engine rebuild this week. The car is a Porsch=
e 914,
but the break-in info should be the same. My reference is the book How=
to
Rebuild Your Air-Cooled VW Engine. The break-in info is, in my
paraphrasing:
1. When the engine first starts, run it at 2,000 RPM for 20 minutes to =
get
oil pressure up and keep everything lubed while it wears in.
2. Drive it for about 25 miles. During this drive, accelerate at 3/4
throttle from 20-50 mph and then close the throttle and let the engine =
brake
the car. Repeat 5 times. This helps shape the rings to better seal bo=
th
positive and negative pressure.
3. Change the now-dirty oil and adjust the now-seated valves.
4. After 300 miles, repeat step 3.
During all of this, check often for leaks, especially fuel, and for loo=
se
fasteners. Also, I believe you need to re-torque the head bolts at som=
e
point.
I hope this helps.

Subject: done and driving....
what a great day. all this talk about weather means absolutly nothing
to me right now. i happen to live in western new york, but i just
finished my engine rebuild yesterday, and drove the car to work today.
what a great feeling. even though the weather is coming down (not
literally, yet), i am going to be driving my spit a lot, for at least
the next few weeks.
ok, now onto the question, i would like to know anyone's opinion on
breaking in an engine. anything at all. however i have just one
thing to add, i would like some sort of reasoning as well. some of
you seem to give your opinion without a reason sometimes. now, i
don't mean to sound harsh, but before i do anything to my spit, i like
to know why i'm doing it. thanks for you input in advance.
