"What causes engine 'tick'”

Q. When I first start my car in the morning, I hear a ticking noise coming from the engine. It's a 2003 Ford Escape Limited with a V-6 engine and 70,000 miles. It goes away after 30 seconds or less and doesn't do it upon subsequent warm startups, like after a visit to the grocery store.

It is always hard to know exactly how much oil is too much, so it's best to get it right on the nose. While the oil level being exactly on the line is not as critical on your car, it is extremely critical on some of the newer vehicles. The oil level has to be right or it can set computer codes in newer models, and in fact some of the hybrids won't even start.
