Geoff,
I've got 4500 miles on my total rebuild and had the same concerns as you,
starting at 2000. I was told by 2 mechanics that they've experienced rebuilt
some engines taking over 7000 miles for the consumption to settle down. I
still burn oil, about a half quart in 400 miles but it's increasing.
I've experienced different rates of oil consumption with different oils, too.
When I was pouring in a quart every few days, I kept the crankcase filled with
Amoco Gold 20W50, an inexpensive oil I got from the local discount warehouse.
Oil consumption never slowed down. Upon advise of a mechanic, I've switched to
Kendall 20W50, a racing oil. The mechanic stated he uses it for his rebuilds
and thinks that the issue may be due the amount of additives in the Amoco vice
the little or no additives in the Kendall. In my case, the oil consumption is
diminishing.

>TR6 consume and how frequently? I ask because, my TR6 has around 2000 (two
>thousand) miles on its rebuilt motor, but from the minute I got it back from
>the shop that rebuilt it, it consumed a fair amount of oil. For instance:
>at the start of a 500 mile round trip to St Petersberg, I popped the bonnet
>and topped off all fluids. Upon my return, (those of might remember I
>couldn't get the car started 20 miles from home, but that's for posterity)
>and checking the fluids, I was exactly one quart low on oil. External leaks:
> one small one, I think from the timing chain cover, but looks like nothing
>substantial. Plugs: a light coating of oil around the threads, but the
>electrodes themselves are a lovely light nut brown and dry. Smoke: none on
>startup, and none whilst driving. Should I be concerned?
>Thanks and Regards
