Hi Mike,
Based on my experience this is completely normal, especially with larger than
stock push rods. I pour a quart of oil in and wait five miutes or so before
adding the next quart. Works the same for my 948 and 1275 engines.

PS - I'm enjoying the sunshine in Hesperia for the next few days. Hot up
here!!! :-)
