Bert--
You don't need and should not use any sealants with the oil pump line. The
AN threads/fittings are designed to seal on tightening. BTW not all of
these oil lines are created equally: After my original copper line broke
at the block end (luckily I just happened to have my eye on the OP guage,
saw the needle fall and shut down in time to prevent catastrophic damage) I
ordered one through a major Healey parts supplier. They sent me one that
did not have swivel fittings at both ends and installation was not easy.
The DW pipes have swivels at both ends.
If the engine was not run in properly--which I would define as 20-30
minutes of continuous running at 2500 or so RPM's with oil containing high
levels of ZDDP--there is not much you can do about it now, as whatever wear
that took place to the tappets and cam surfaces is irreversible. So I
would simply hope for the best and pretend you are starting out from
scratch. If the cam/lifters go south they will do so in pretty short order
and you'll see it in the tappet clearances and general flat performance.
Run it in, drain the oil and change the filter and let us know how it goes.
