Did you or do you have any starting problems with vehicle? Milky oil may be a cause of too many short trips, is that possible?

Length of oil dipstick for a 2002 dodge ram 1500 4.7 v6 cause when I try to check oil with the one that is there the oil is way up past full mark


The 4.7L is a V8. Did you just get the vehicle? Has the oil been at the normal level until now? Check the color of the oil - if it looks milky, you may be getting coolant in your crankcase making it overfull. If the oil looks normal (clear and clean), find someone else with the 4.7L engine and compare dipsticks.

1999 Pontiac Bonneville-My fans don't work, lose coolant very fast not sure where it's going? Hasn't overheated, but I don't drive far. Planning to take 1500 mile trip at end of month?, no...


I assume it's the 3.8 V6? They are notorious for intake gasket problems. The fan problem could be a few things, fuse, relay, ECT (electronic coolant temp sensor), ECM, Do the fans come on when you run the A/C? Hope this gives you some ideas. Let me know a little more and I'll try to help. TJ

Have very slow water leak.. can not find where it is leaking at . checked oil and it looks milky


milky oil would suggest water has mixed in with it. this added to a slow, unfound water leak points toward a head gasket problem with the coolant escaping from the cooling system, into the oil.
this needs to be sorted out fairly quickly. apart from the obvious problems of a water leak and the risk of overheating, oil with water in it will not lubricate the engine properly and there is a serious risk of engine seizure.
a garage should be able to do a simple test on the oil to discover if it is coolant contaminating the oil.
a pressure test on the cooling system would also confirm where the coolant is being lost.

When i checked oil it looked milky


water or coolant is getting in oil. could be a bad head gasket. If the coolant level continues to drop, but there are no signs of coolant leaks on the ground or from the exhaust pipe, there is a good chance that coolant is entering crankcase and mixing in with the oil. check head gasket and manifold gasket for leaks.

Head gasket


depends where its blown if your oil is milky looking and thick or it blows out all of your coolant if you have rad cap of ff you will see bubbles in rad either will indicate a bad gasket

1997 pontiac bonneville 4 door v-6 coollent leackage but no signs of leakage,lose of power, lose of oil pressure, trubles starting at times.


You may have an internal leak. It could be leaking into the cylinders past a head gasket. Check the spark plugs. Pull one out and if it has white residue on the electrode then it's burning water/coolant. Also check the dipstick. If it has a sort of frothy watery looking oil on it, then you're leaking into the crankcase.
