Sorry absolutely no idea with my head under the bonnet -hood- Now has the opil been changed regular like every 5/6000 miles if its gungy and old then chances are you have knocked a big end out or two ,best advice is to trade it in quick whilst it still runs

SOURCE: low oil pressure indicator at low rpms (idle) '97 olds V8

Low pressure when at idle, after the engine has warmed up and the oil has thinned, indicates that the oil pump is worn and needs to be replaced.

SOURCE: engine knocking on toyota corolla after replacing damaged sump

oil pan and sump damage are very likely to lead to oil distribution problems, this is not temporary, if you hear a knock have it checked by a local mechanic who can verify it for you, it is possible that the engine is damaged internally.

SOURCE: Smoke comes from around engine

If you saw where the oil came out then that is the repair needed. It may not leak enough oil to get to the ground. Engine temp will make the oil leak smoke before it ever hits the ground. It may be valve cover gaskets because when they start to leak the oil gets all over the exhaust manifold and the exhaust manifold runs very hot. Rate if this helps

SOURCE: 99 olds silhouette check engine light

When a catalyst damaging problem occurs the check engine annunciator will flash and the vehicles computer (pcm) will shut down a cylinder. This flashing light and rough idle is a warning. Usually prolonged engine operation with flashing annunciator will ruin the catalytic converter. ($400.00++ to replace) Important that problem is fixed before operation of engine is continued. Check the ignition leads in the back (right side) for chaffe damage or burns from exhaust collector. Could also be a mechanical problem. Do a compression check. Start there. How many miles on vehicle.

Mitsibushi pajero oil light time


White SWEET smelling smoke, or white OILY smelling smoke? If it's white thick SWEET smelling smoke, you have a blown head gasket - that's the smell of antifreeze burning in the engine, which it should NEVER do. If it's white OILY smelling smoke (smells a lot like diesel), then you're getting too much fuel into the cylinders.

If it's sweet-smelling smoke (antifreeze), pull the oil dipstick & check the oil level. If the oil level is HIGH and the oil looks like a mocha milkshake, that's absolutely conclusive - that's what happens when antifreeze gets into your oil, and it's nasty corrosive to engine parts.

I'm not at all surprised that the oil light is on if it won't start - you won't get much oil pressure until the engine is running.

98 lincoln navigator loud noise, shaking, high rpm at idle, drive


I don't know how much oil you had to put in but it sounds like you have maybe more than opne issue and both sound major. One is engine reving and speed not picking up sounds like trans problem. Two the engine shaking and making noise and being run low on oil leans toward possible engine damage. If your mechanicly inclined check all fluids and when checking trans fluid smell it. If it smells burnt the trans has been damaged. Check oil pressure and make sure coolant is full.You may have to take it into the shop.

High RPMs


yes its related to knock sensor because car is running rich in fuel, and car runs of on safe mode, so overdrive will be off. have you and a friend replace it. remove intake assembly, then intake manifold, but first remove your anifreeze from radiator, trust me you want to remove antifreeze! their are brackets by the fire wall to hold down the manifold, thats the hard part is taking it off and putting that on since not to much space to work on it. on the block you'll see the two knock sensors, has 2 wires each, knock sensors cost between 150- 200 a piece, still cheaper than dealership putting it on. also buy some liquid gasket because you will need that. after putting it all back together reset the ecu and you should be fine,
