 Should
the oil filter and circulation system on an early
3 Litre (or any other Vintage Bentley) be maintained
as original or can it, or should it be improved
or replaced? There have been several attempts
in the past and apparently with good results.
One disadvantage is that originality is altered.
In some cases, drastically. There have been several
replacement filter systems suggested in the past.
Going a step further are the modifications that
were done to The Great American Racer, an early
3 Litre owned by Dick Burdick that has made several
rally runs across the United States. The objective
was to limit engine wear and increase reliability
with a modern oil pump/filter system on chassis
392.
View photos of this system on his chassis
page. When the engine is started, the pressure
is instantly high and remains high at idle and
under acceleration and deceleration. It is not
just a modern oil filter. His mechanic said a
modern oil filter alone would not work because
it would restrict flow efficiency. A modern oil
filter needs a pressurized system.
Vintage Bentley owner and restorer Alan
Smith made these comments which readers
will find of interest:
"A few years ago
some American Bentley owners such as Bill Porter
fitted pre pressure oil systems to their engines.
These systems used an external oil pressure source
that would pressurize the oil system prior to
starting up the engine, the theory being that
this would minimize engine wear as the engine
normally rotates several times before the oil
pressure pump is able to bring the system up to
pressure.
Looking at the photos of Dick Burdick's car I
can see that the oil filter system is the same
as on my engine in that he has fitted a full flow
oil filter but there is something else that I
can't identify but I suspect that it is an external
pressure device.
The modern full flow oil filter that I fitted
to my car is the same system as on a modern car
but on a modern car the filter is fitted to the
side of the crankcase to an internal oilway.
I don't know anyone that has fitted this external
oil pressure system, the only way to know if this
system does work is to do comparison tests on
an engine that is fitted with the system and on
an engine that is not fitted with this system.
I suppose it's just too much work so we will never
know!
Perhaps you can ask the mechanic if such tests
were carried out but I bet that they weren't,
so this theory is really unproven.
The filter system that you have (on your car)
at the moment is fine, is full flow but liable
to failure if water is in the oil. The solution
is to fit a full flow external oil filter which
has a bypass fitted such as the one on my car,
making sure that the filter is mounted in the
correct direction relative to the oil flow (direction
arrows on the filter nozzles will show this).
As regards wear on start up, a good synthetic
multi grade oil will help but as nowadays the
cars are just languishing in the garages and never
taken out — this problem with wear is really
just academic."
My response was that my discussion with Dick Burdick's
mechanic/restorer was about 20 years ago and the
Burdick museum was closed and the cars sold. I
would think the subject of filters and oil pumps
is worthy of discussion. After all, we do not
want our engines to wear out and technology has
changed. Is there a better way or was W.O. Bentley's
way adequate? What are your solutions? Do you
have a revised system? Is there one being produced
to our cars? Your comments please.

| The
conspiracy to kill off Bentley Motors |
| By Alan C Smith - Vintage
Bentley owner & restorer |
|
|
"The reader may perhaps consider this title a
little dramatic but a document has come into my posession
that can throw some new light over the demise of Bentley
Motors. This new document, of which I will apprise the
reader shortly, set my mind racing and I started to
reread all the relevant Bentley literature.
There is a difference between just reading through a
book and reading to obtain information from a book.
Innocuous statements out of context can be read in a
different way when a particular theme is being pursued.
In this article I write down my conclusions but ask
any reader who has better knowledge to come forward
and enlighten us where there is any doubt about the
subject matter." |

1930s adventures of 4½-litre Reg JB 1850 |
| Memories of a super-charged 4½-litre
Bentley in a variety of countries. |

"Reading of other's experiences
with vintage cars has filled me with nostalgia for one
of my own of long ago — surely one of the most
entertaining high performance cars ever made —
a supercharged 4½-litre Bentley. I shall always
remember my first sight of the 'blower'. I had an ordinary
4½-litre at the time and had driven up to H.
M. Bentley's in Hanover Street to discuss some modification
— and there in the showroom stood the perfect car,
a 4½ with a shining black open four-seater body
with screen folded flat and two aeroscreens in position:
I had to have it and a deal was struck. 'H.M.' had had
the engine stripped and new bearings fitted as well
as everything else possible done and I started off with
a virtually new car and drove it 75,000 miles with only
normal decoking and brake relining having to be done
in the course of them." |
