Upgrading a 1978 Ferrari 308 GTS: Engine Lubrication System

February 20, 2013 Comments (0)

In 1995 I bought a 1978 308 GTS Euro spec Ferrari with a rebuilt engine and 13K miles on the long non-functioning odometer. It had had a serious accident on the right front corner. This is the second in a series of short articles about how we repaired and updated it.

Auxiliary Oil Accumulator System

Two weeks after I had taken possession of the WASRED 308, I had coffee with a veteran 308 owner. I mentioned that I thought the wiper system was rather weak. “Wasn’t really designed for use in the rain” he replied in a manner that implied my expectations were rather high. Pressing on, I mentioned that the oil light comes on when I drive around a sharp corner. Don’t worry about it, he said, they all do that.

But I do worry about flashing red lights above the word “Olio” on my dashboard. John Tirrell, of Independent Ferrari Service in Easton, MA, again came to my rescue. The problem is indeed common to all older 308s and peace of mind comes from the installation of an additional three quart oil container from a company called Accusump.

The Accusump Company of North Brantford, CT, manufactures pressurized oil accumulators for performance engines. Accusumps are oil reservoirs that connect to the engine's oiling system. They are designed to collect pressurized oil from your engine and store it so it may be discharged when oil pressure is low. Accusump Oil Accumulators deliver oil before starting, to eliminate dry start scuffing (pre-oiling), and discharge oil during low oil pressure surges.

This is not an installation I could do myself so John had the hoses made up and fitted the Accusump to the trunk compartment of my car. A single hose goes from the accumulator to the base of the oil filter mount. It is a fairly clear path from a couple of angles. There really is no excellent location for the unit and the trunk is as good as any. I have seen pumps fitted to the wall of the trunk area above the headers and I have considered that change.

So, as you can see from the pictures it is a clean fit but it does have drawbacks. For one thing, the heat generated by carrying along an extra three quarts of hot engine oil means things get toasty in the luggage compartment. Then again, with a set of headers abutting it and an exhaust system under it, it was never intended to store milk and butter.

In Chapter #3 we will talk about exhaust headers and sound.
