Description

This Td5 injector seal kit includes both the O rings and the copper washers.  When these parts fail you get two very different symptoms/problems.

Injector Copper Washer Failure generally allows combustion gas to escape causing poor starting, rough running and often completely cutting out.

Injector O Ring Failure is the one you may not notice immediately.  When the O rings fail they allow high pressure fuel to escape in the engine and mix with the oil.  This gradually fills your sump with diesel, dilutes the engine oil and can cause catastrophic failures.  This is one very good reason to check your oil level regularly – you’re not always just checking if it needs topping up – you’re also checking it isn’t topping itself up.

So one issue is inconvenient, the other is much more serious.  This kit solves both issues at once.
