I now have 1500 miles after a rebuild (1000 miles on the oil change after the break-in period). Today I checked and the oil level was down to the minimum line, so I had to add about 1.4 pints (.7 litres). Is this normal?
That's not too bad, the rings have to seat. I believe adding 1 liter per oil change (3000 miles) is normal. some engines use less, but it shouldn't use more.
BTW, how do I break in an engine?
I drive it like I stole it.
Mark is right. Drive it like you stole it, but do run it a constant speeds. Hammer it from time to time. Rings probably have not set up yet.
1500mi and rings not seated? That seems long to me, no? I am not an expert.
My questions would be:
Were the cylinders honed properly?
Were the pistons and the bores measured for trueness and matched?
Those are two biggies that will screw you every time. I have learned this before a long time ago
Depends on the brand of rings. Seating time varies widely from brand to brand.
