Robert,
I get a puff of smoke when I start the car after driving it somewhere and
stopping for a short time.
Here is the description of the "fix" that is in the Rimmer catalog:
The Rocker Feed Kit and Oil Consumption.
When the supplementary oil feed to the rocker gear is fitted on the Triumph
TR6 engine an increase in oil consumption is often encountered. This is
attributed to oil being drawn down worn valve guides. The extra amount of
lubricating oil flowing through the valve and rocker chamber, as supplied by
the feed kit, exaggerates any tendency for oil to be sucked down worn valve
guides past worn valve stems. The best solution is to fit new valves and
guides, but this is not always on the top of the repair priority list. To
assist in the reduction of oil being sucked down the guides a method of
valve stem oil seal is required. We offer the simple do-nut rubber ring that
is used so successfully on MG sports cars. Its part number is AEK113, 12 of
which are required, one per valve stem, to service an engine.
Now the clever bit... How to fit them without removing the cylinder head
from the car.
Each seal needs to be fitted to the valve stem above the valve guide but
below the valve spring upper retaining cap(s).
Remove the rocker cover, rocker gear and the spark plugs. Cover the holes
that the push rods come up through so nothing can be dropped down into the
engine. Turn the crankshaft so that number one piston is at bottom dead
centre (BDC). Feed a length of clean, pliable rope down the spark plug hole
of number one cylinder, leaving a bit hanging out so you can retrieve it.
Now, slowly and carefully turn the crankshaft clockwise by hand, a
resistance will be felt as the rising piston in that bore compresses the
rope against the combustion faces of the two valves in that cylinder,
holding them against their seats. The valve collets and spring caps of that
cylinder can now be removed without the fear of losing the valves down the
bore. The valve stem oil seals can be fitted to these two valve stems and
perhaps a new set of valve springs. Be honest, this tip has saved the cost
of a decoke set! Once the valve stem oil seals and other parts have been
refitted to this first pair of valves satisfactorily, simply turn the crank
anticlockwise to BDC, withdraw the rope and repeat the process on the
remaining five cylinders and five pairs of valves.
To be sure that the rope has compressed sufficiently against the faces of
the valves, attempt to push the valves by hand, as if being acted on by the
rockers before removing the spring caps or collets, this is the fail safe
check.
This method can be adopted anywhere as it does not require the use of
compressed air, special tools or luck.
Does it seem like it would work?
