Hi would appreciate any advice you can give me, I bought my jeep brand new and have maintained it, I have recently started hearing a loud knocking sound in my engine when I first start it up in the morning it lasts about 1-2 minutes then it stops. Thanks.

OIL LEVEL?

OIL PRESSURE?

DO YOU CHECK YOUR OIL AND COOLANT LEVEL WEEKLY AS PRESCRIBED IN YOUR OWNERS MANUAL?

OIL CHANGED ON SCHEDULE?

WHAT KINDA OIL DO YOU USE. WEIGHT. SORTA WHERE DO YOU LIVE? (ALASKA OR PANAMA?)

TICK-TICK-TICK-TICK-TICK-TICK?

TAP-TAP-TAP-TAP-TAP-TAP?

KNOOOOCK-KNOOOOCK-KNOOOOCK-KNOOOOCK? (LIKE HOLDING A SLEDGE-HAMMER HANDLE VERTICAL W/ THE HEAD 4 INCHES OFF THE CONCRETE FLOOR AND REPEATEDLY DROPPING THE HEAD ON THE FLOOR?)
