8-2 Cold Start-up Oil Leak

LH Side of Engine

BritCar ServiceInsufficient tightening of the TR6 factory oil filter bolt and/or use of more than one (1) filter sealing neoprene “O” ring, can promote cold start-up oil leak due to initial high oil pressure in the oil filter body, (viscosity/system inertia related). A small amount of oil can be forced under the filter housing seal on start-up. This condition only exists for a few seconds. Use of the correct filter sealing ring and adequate tightening of the oil filter housing bolt will usually correct this condition.
