Catch Tank/Breather

Recommended Posts

Looking around at catch tanks on the market, there isn't one that can take a 19mm intake hose, has a pressure release oil cap, sight guage and can mount somewhere sensible.

This is a modification of a standard Mocal (or copy) 1litre tank. It comes with a pressure relief cap, (should the breather filter become blocked). Directly under the water tank on the S3T there are two brackets welded on the chassis. No idea what they are for, but with a bent up bit of ally rivetted to the tank, it sits nicely between the two brackets.


The tank inlet is modified with a 1/2" BSP to 3/4" hosetail. The spare inlet is blanked off with a 1/4" BSP plug. An extra hole is cut in the top to take a 3/4" hosetail. We therefore have 19mm of airflow from the engine all the way through. The K&N filter is 19mm but can be replaced with a hose back to the air box. The whole thing sprayed black to suit the rest of the engine bay.


Sits nicely on the chassis bracket, with easy access to the drain plug


Picture from above, out of the way. 19mm Heater used to join up to the original pipe out of the engine


Survived the run up to Donny & back, no more dipstick flying out! :rofl:
