I would have to say your engine is probably shot. The bearings are probably gone. It is possible, i suppose, that your oil pump is faulty. As soon as the oil warms up, and becomes thin, the rods and lifters start to rattle. The same goes for the oil pump, as oil becomes hot, and thin, it may not be pumping properly. I would try a used oil pump, and see if there is any difference before i wrote the engine off.

Lifters rattling and engine oil light is on? 1998 ford taurus...lost!

Will tappets on a pontiac 3.8 start rattling after motor overheats?

it can if the motor got very hot. you may have poor oil quality from overheating. damaged valve lifters, damaged camshaft/bearings, oil pump, water in oil which can cause engine damage from overheating. it will have to be checked out to find what caused the overheating then the lose of oil pressure to cause the rattle.

Why does my cars lifters make so much noise when i first start the car?

this will be from , incorrect oil filter ( cheap units are missing a non-return valve which keeps oil in the lifters), wrong grade of oil ( viscosity to low for the wear on the engine go up to 30w-50), worn lifters (replace), low oil pressure in the system.
Most lifters that have seen some miles will rattle for up to 10 seconds until the oil pressure builds up but any longer and I would consider replacing them

1993 ford f150 oil pressue gadge running low after truck warms up

I would put a oil pressure gage on the truck and verify that the pump is good. The lifters should not rattle unless someone has been adjusting the valve lash. At 196000 miles the lifters maybe getting weak, push rods could be wearing.

I have a 99 vw passat with lifters here's how it went. I was passing a car when my check oil light came on...I stop check the oil, within a few minutes the lifters started clacking, I...

You should perform an oil pressure test and see if the engine is producing oil pressure within specification. If it is, the lifters may quiet down over time.

My 1999 Ford Taurus has the check engine light and oil light on. The lifters are rattling. I removed the oil pump and put a drill on the shaft and it pumps oil. Do you know what else it could be?

Just because the oil pump is turning doesn't mean it pumping enough oil. I think the first thing you should do is get a mechanical oil pressure guage hooked into the system and read the oil pressure you actually have. This will determine what to do next.

If you have a high mileage engine then perhaps a thicker oil may fix the noisy lifters. Go to 10W40 or maybe even 20W50. This should stop the lifters from rattling and boost your oil pressure if it's low. A compression test would help to confirm the wear from high mileage.

It could also be that the oil passages are partially clogged and while you have enough oil pressure, it's not getting where it needs to be in sufficient volume. If this is the case, I would try using an oil additive to help clean it up. Just be sure to increase the frequency of your oil changes to keep the crud out of the oil system.

It's also possible that your engine has enough wear and tear from mileage that it will need to be overhauled or replaced. Generally a good used engine is cheaper than a rebuild. Be sure to check out the warranty from the scrap yard first. Hope this helps.

My 2000 Nissan xterra started shaking while idling and the service engine light came on. I changed the oil and it feels better. It doesnt knock In neutral or park. It also rattles till you hit about 30...

Also- the rattle is most likely the valve lifters. The lifters on this engine and the model previous (I have owned both to 180k miles or more) lose pressure when the motor is off. They re-pressureize with engine oil after the motor starts and tap a little until they "pump up" to full size. Just don't drive until the rattle dies down and as long as it is under 30 seconds or so- you will be fine there.

2003 Taurus. Oil light came on. Checked level. Good. Drove another 5 miles, now have engine knock on top side of motor. Thought maybe oil pump malfunction. In the middle of nowhere, drove 50 miles home....

Before driving it anymore I would have someone test the actual oil pressure using a mechanical test gauge to see how much , or little, oil pressure you actually have. The knocking noise could be a hydraulic lifter that is partially collapsed due to low oil pressure or a rod bearing that has been damaged from low oil pressure. If it is just a lifter that is making noise then there's a pretty good chance that the lifter will quiet back down once the oil pressure is normal again. If it turns out that your oil pressure is normal both at an idle and at highway speeds then the noise may be unrelated. You can cause some serious damage by continuing to operate any engine that is low on oil pressure even if the dipstick shows it to be full of oil. Hope this helps and good luck!

The engine valves are rattling like a desiel, on my 1998 ford explorer 5.0. How can i solve this?

This engine has hydraulic lifters that depend on clean oil with good oil pressure. Check the oil dipstick for proper level. Try an oil additive that is supposed to help sticky lifters. If no help, you may need to replace the entire lifter set which requires removing the intake manifold and removing the rocker arm assemblies to get to the lifters. If the engine has high miles, you may need other repairs as well. Good luck!

Loses oil pressure

Have u verified the oil pressure with a mechanical guage? this may just be a sending unit, if the engine had no pressure the lifters would be rattling like crazy at idle.
