You're aware that driving it 5 miles twice a day isn't enough to get everything thoroughly warmed up.
I would suggest planning a nice scenic route of approximately 100 miles for next weekend. Something that is not all highway, not all in town, but allows for a variety of throttle positions and loads.

PROPER BREAK-IN IS IMPORTANT/BREAK-IN PROCEDURES
Fast idle until normal temp is reached
As soon as the engine is started,set the idle adjustment to produce an engine speed of around 1,200 rpm.this will insure
a good oil pressure and throw-off will be sufficient to lubricate
adequately the cylinder walls. operate the engine at this speed until normal operating tempature is reached(usually 15 to 20 minutes.
If for some reason it was not possible to pressurize the lubrication system before starting the engine,a few squirts of
engine oil should be directed into the carburetor air horn during the first minute or two of operation. This will provide cylinder lubrication until bearing throwoff and "split hole"lubrication takes over.
Check oil pressure and coolant temperature occasionally during warmup.Check coolant level as there may have been air in the system when filling.Inspect for any signs of gasoline,oil or coolant leakage.

Drive the vehicle to a spot where you can SAFELY reach a speed of 50 mph.Accelerate rapadly up to about 50 mph.Immediately let up on the accelerator and allow the car to coast down to around 30 mph.Drive at 30 mph for a block or so and again accelerate rapidly up to 50 mph. Once again, coast back down to 30 mph.
Repeat this procedure fifteen to twenty times.
When slowing down,watch for cars behind you. | | | | | Joined: Feb 2009 Posts: 400 'Bolter | | 'Bolter Joined: Feb 2009 Posts: 400 | Between break-in and road test,retorque and check head bolts and valve lash. | | | | | Joined: Jan 2007 Posts: 161 Shop Shark | | Shop Shark Joined: Jan 2007 Posts: 161 | what I did after installing a new piston and doing a valve job, is just drive it. will change the oil this weekend (after approx. 200 mls). just take it easy the first 15 mins or so, and after a few days, run it for half an hour and adjust the valve lash. retorqueing essential bolts is a good idea, plus: check everything for the first few days. | | |
