j.---The oil pressure seems right, as is the usage during the break-in
period. Oil going thru a hot muffler usually will make for some smoke,
so be sure that what you see is not oil blowing out from farther
upstream and collecting on the rear of the car. Don't be fooled by a
mix of carbon and water, that can appear to be engine oil at/out of the
tail pipe.
Never hurts to do a leakdown test.

I have a 74 tr6, recent head rebuild, new valves,seats,guides, lower
engine new rings,cyclinder ridge cut and new clam shells on rods; that
was 1000 miles ago; using 20-50w racing oil; have used now 1.5 qts, oil
pressure around 30 when running over 1 hour; 20-25 at idle;start up
until warm 75 psi; some wet oil blow out present from exhaust-no smoke;
is this normal?will have tappets adjusted next week,head was re-torqued
at 600 miles.if not normal should I consider leak test, could something
have gone wrong with valve etc?
