Premium-Quality Ignition Rotor

While prices have fallen, so has the quality of some ignition parts. Luckily, we work with a number of

suppliers here and abroad who are reversing the trend. A good example is this heavy duty ignition rotor.
Some background: recently manufactured rotors are not like what Lucas manufactured when classic Jag-

uars were new. Newer rotors have much more carbon black in the plastic, which increases its conductivity. Original
contacts were molded into the body of the rotor; replacement rotors use a rivet, the tip of which is very close to the

spring clip on the underside of the rotor. Because the high-energy spark from the coil will follow the path of least resistance, this
path can pass through the rivet and spring clip and ground out on the distributor shaft. This will cause a “miss” that will only go

away temporarily when things cool down. Our new heavy duty rotors are made from a non-conductive resin and the brass contact
is molded to the body; no rivet means no chance of conductivity. Finally, the socket is precisely sized for a tight and accurate t.

Highly recommended. The DRB106 rotor ts all XKs, all six-cylinder E-Types, all early sedans and XJ-6 Series I and II with points.

Rebuilt SU Fuel Pumps

Calling these pumps “rebuilt” doesn’t do them justice. “Re-manufactured, improved and restored to perfection” comes a little

closer. All internal components are replaced and all seals and gaskets are ethanol resistant. The Viton diaphragms are exclusive
to our rebuilder and are rated to withstand 25 percent ethanol. Finally, all pumps are converted to pointless style and are 100

percent solid state. In many ways, these pumps are superior to a brand new SU pump and are cosmetically as new with re-plat-
ed hardware and all labels, etc. An excellent value. Core Charges Apply.

ZDDP Oil Additive

We realize the words “oil additive” are
likely to peg your B.S. meter, but hear

us out. Zinc Dialkyl Dithio Phosphate
(ZDDP) is a critical anti-wear ingre-

dient in motor oil. It’s being phased
out because the small amount that

sneaks into combustion cham-

bers reduces the service life of
catalytic converters. For modern

roller-tappet engines, the reduction
of ZDDP is not of grave concern,

but for at-tappet engines such as
those tted to Jaguars, it is of critical

importance. ZDDPlus restores this anti-wear NEW V-12 Cylinder Liner Hold-Down Set
agent and ensures proper lubrication. Sold per
Not something you’ll need every day, but if you work on Jaguar
4-ounce bottle, which will treat 4-5 quarts of
oil. Please note that ZDDPlus cannot be used V-12s, this set of ten cylinder liner hold-downs is essential. Made by a
small shop in the USA. Quality is excellent with .125” wall steel tubing
in cars equipped with catalytic converters. For
retained by 1/8” x 1” steel pins.
