One of the great things about the Triumph 6-cylinder engine is the amount
of wear it will tolerate and still keep working!
I always offer the same advice for these engines - the oil pressure thing
comes up frequently. If the engine has done about 60K - 70K miles, then
it's time to get the crank ground, put in new shells and an oil pump, and
the lump will go on for another 60-70 thousand without any trouble. The
only real problem with Mr. Triumphs' engine (or should I say Mr. Standards'
engine?) is that it's a bit short of bearing area, so this is the bit that
fails first.
One other thing - if you've an Injection TR6 with the 125BHP 'emissions'
engine, the camshaft and followers (lifters?) will need changing at about
the same time - this is the infamous 'three-ring' cam which wears like
mad!!
