|Any engine fitted with a full flow oil filter may be adapted to take an oil cooler. This is achieved in various ways.|
|Type A||A sandwich plate fitted between filter head and filter bowl. In certain cases there is insufficient room to fit a sandwich plate, in these instances it is sometimes possible to obtain a filter assembly shorter than the original fitting. We can advise if such filters are available for any particular engine. Our sandwich plates for engines with spin on filters can have built in thermostat.|
|Type B||A sandwich plate between the filter assembly and cylinder block.|
|Type C||Discard the original filter head and replace with a filter head tapped to take the oil flow.|
|Type D||The original filter assembly may be relocated and instead of a sandwich plate, a take-off plate and remote filter may be fitted, see below. In the case of the Triumph Dolomite and Stag a cover plate on the block may be removed and replaced with a special take off (TOP7/7B)|
|Type E||For the Rover, Buick, Oldsmobile, V8 where space can be very limited we can supply a replacement oil pump cover with outlets for a remote filter plus oil cooler if required.|
|Type F||For the 6 Cylinder Triumph engines where there is not enough room to fit a Type A plate we provide an adapter turning the filter through 90º, For convenience this takes a spin on oil filter|
|Type G||In the case of BMC "A" and "B"series engines an external oil pipe may be removed and replaced with hoses running to and from the oil cooler. "A" series have 1/4 NPTF & 5/8 UNF use HEM8-4-8 & HEM1-7-8 hose ends or suitable adapters. "B" series have 1/2BSP threads, use suitable adapters.|
|Type J||The Volkswagen Beetle and Porsche derivatives have an oil cooler fitted to the engine as standard, this will be insufficient for modified engines and also blocks the air flow to number 4 cylinder. We provide an adapter to fit in place of the existing cooler with 3/8NPTF connections to cooler. Consideration may be given to fitting a remote oil filter in the cooler circuit, the original engine having no filter, we advise fitting a part number 500 valve in place of the original combined oil pressure relief and cooler bypass valve, this ensures oil flow through the filter at all times. An oilstat can be used to control flow to the cooler.|
Take off plates for use with remote filters:
It is sometimes desirable to relocate the existing oil filter due to lack of space brought about by engine changes, installation in kit cars, fitting an oil cooler or in a dry sump system. We have two types of take off plates that fit in place of existing spin on filter to allow for connection to a remote filter.
|Type H||Top take off, TOP will require a minimum of 4.5" clearance including hose fittings and adapters.|
|Sideport take off, TOPO will require only 2.5" clearance. Can be turned to face any direction.|
Part Nos. SP1/A/B/C/DE/F/G can have thermostatic operation, prefix part no with OT, e.g. OTSP1. Alternatively they may be tapped to take an oil temperature gauge prefix with TGA.
Threads on SP1/OTSP1 & TOP1/TP01. Suffix: None is 3/4UNF male/female, A is 5/8UNF male/female inverted, B is M16 male/female, C is 13/16 UNF male/female, D is M18 male/female, E is 5/8UNF male/female, F is M20 male/female, G is M22 male/female.
*We have also made a quantity of sandwich plates from billet aluminium to fit the Japanese microfilter which are of slightly smaller diameter than the new SP1. They are called SP2A/B/ etc.
For remote filter applications where no take off is shown, the only solution is to use a sandwich plate together with the existing filter bowl with the filter removed, if space is limited, bowl and center bolt must be cut down to suit.
