Hello. I have a 07 Dodge Magnum. I had an oil change and an inpection done on my car a little over a month ago. A week later, my starter went out. Two weeks after that, my car was already out of oil. Now, my engine is tapping and/or knocking with smoke coming from the muffler. What could be the problem?

SOURCE: audi engine oil leak?

Sounds like a leaking valve cover gasket. The parts are around $50 to do both cylinder heads from www.ecstuning.com. It's not a major issue, but it may be a sore point to a potential buyer.

SOURCE: 98 f150 4.2 110.000 miles went to start up engine started clacking and smoking out exhaust

the intakes go bad on these engines....... they leak coolant in the cylinders and cause a hydro lock that causes the rods to bend making the piston skirt hit the crank......" clicking noise" theres a law suit in progress for this issue......... you can find info on the internet

SOURCE: coolant leaking on manifold, steaming.No hose or radiator leak.

i think its going to be the head gasket duto the way its leaking coolant. one of the water jackets maybe i would have it checked to be sure but it sounds like head gasket

SOURCE: Oil Change two weeks ago and oil level is low already???

I assume you have no leaks as you say. Your van does hold 5 quarts of 10w30 oil with filter change. The level was 1/4" above the add mark, which is less than 1 quart low. You drove the van 1,300 miles so it is very possible that it could burn that much oil in that many miles without you seeing much smoke. Top it off and have someone else drive it. Have them get up to around 60 mph, then let off the accelerator and let it coast down to 30 mph, then accelerate fully while you follow in another vehicle. If your van is burning oil you will see a big puff of blue smoke when they accelerate after coasting. If you do not I would suspect you were cheated out of about 1/2 quart of oil. You would not be the first person this has happened to. Top it off and check as I described and then check the level after driving another 1,300 miles. If it is still full find another place to change your oil as the place you went are crooks.

it could be either,main bearings or rod bearings,you seem to have a handle on it,now all we can do is take bets when the big knock happens!
