A vacuum leak can cause the engine to idle high, but worse than that it can cause one or more cylinders to run lean. That can result in exhaust valves and pistons running at a higher than acceptable temperature and cause premature engine failure.

How many miles should you be able to drive before needing to replace a head gasket seal?

A head gasket does not wear out and there is no specific reason for replacing one unless it fails. Usually, head gasket failure is related to engine overheating that causes the heads to warp. Thank you, but it's not the head gasket that has broken. I had the seal replaced last year because it was cracked/leaking and leaking oil. And now the garage says it needs replacing again. Should it been leaking again so soon (after 13,000 miles)?

Normally oil leaking from the top of an engine is a sign that you have a leak at a valve cover. The cover may be loose or the gasket may be defective. Tighten the valve cover bolts to no more than 5 lb/ft of torque. If that does not stop the leak, the gasket will need replacing.

Why would coolant be leaking from behind the main pulley on a 96 V6 Oldsmobile Achieva?

Sounds like water pump needs replacing The main pulley is near the top of the engine. The water pump is toward the front of the engine.

My first hunch is a leaking gasket.

The head gasket sits between the head and the engine block if it is leaking out where you can see the coolant, yes you can smell the coolant if it is leaking into the engine no you cannot smell the coolant.

Where is the Leaking valve cover gasket?

What can a head gasket do?

Head Gaskets are a seal between the engine block and cylinder heads. It keeps oil, coolant, and pressure inside the engine. Usually if its "blown" the car cannot be driven due to lack of pressure in the cylinders. Smaller problems like a cracked or leaking gasket will be noticed by overheating, leaking of fluids and mild to severe decrease in engine performance. Since it is inside the engine usually replacing one involves removing the engine. Cost for repairs can run from $500 to about $2300
