The front crank seal is already out in the open every time the timing cover comes off, and it costs a fraction of the labour needed to go back in for it later. Fitting a new one alongside a cam or timing set change is the cheapest insurance on the front of the engine.

Mr. Gasket 18 Timing Chain Cover Seal Features:

• Seals the crankshaft at the timing chain cover.
• Should be replaced at the same time as a camshaft change or timing set replacement.
• Sold individually.
