So far thank you all for your quick responses.
I was lucky to make contact with a member of the danish Austin Healey Club
who lives nearby and thursday I will go visit him. He will have a look if
the oil spilling is normal or not, he will also check if the valve guides
are worn, and if there are other problems. It4s so nice that people are
willing to help with such short notice.
I haven't tried to run the engine hot or at higher rpm , so I dont know how
much spillage that gives. By reading the archives I got the idea that it
should only be dripping lightly. I maybe misunderstood that.
The engine doesnt normally drip at all, it had the improved rear seal
mounted when it was renovated. I noticed some oil drops from that area after
the long run, perhaps 5-10. I will have to follow up on that continues or
not.
Regarding breaking in piston rings, how many miles does it take?
The mileage in San Francisco in 2007 when it was exported to Denmark was
33,758.
The previous owner had the engine fully renovated because of oil pressure
problems, and only used it a few times.
I bought it in May 2010 with 34,214 miles.
Today it4s at 35,600 miles.
I changed oil and filter in april 2011 at 34,575 miles. 20w50 Castrol
Classic.
July 18. filled up to max with 0.8 litres (0.85 quarts) of oil at 35,250
miles
Today oil at 20% above min, 35,600 miles.
If you have any more ideas please let me know, and I will talk with the club
member i am going to visit. I will return with what he concludes.

It appears normal to me, Niels. When I run my engine with the valve cover
off, it doesn't take long for oil to begin spilling over the lip of the
head. Problems with worn valve rockers and shaft typically manifest as
spurts of oil from the top of the rockers. Have you tried increasing the
RPM to see if the oil comes out of the rockers at more than a trickle?
Do you have oil dripping from the lower parts of the car, or are you sure
the engine is burning oil and not leaking it? I wonder if the new piston
rings are seated properly?

Subject: [Healeys] BJ8 Oil consumption
I have only had the car for a little more than a year and normally I only
run
short runs in the car, 20-40 miles, and havent seen that much oil
consumption,
but when I ran 350 miles this weekend at 60-70 Mph, the oil level went from
almost max to 20% above min. I know the engine has been rebuilt with new oil
pump, a rebore, new pistons, bearings and hardened valve seats before I
bought
it, but I suspect not much was done to the valve train and perhaps valve
guides. I read on this list archives that excessive oil consumption could be
related to a worn valve train, if the cylinder compression was good and
there
appears to be no blue smoke.
Can you tell from these videoes, whether the oil spillage from the valve
train
can be the cause of a high oil consumption.
Cold start
