I have a 2004 ford f150 making a tapping noies can it be the cam phasers going bad


check oil level ---yes it can but tapping noise can be a lot more reasons --worn oil -low oil pressure--low oil level--rocker loose-worn or damaged lifter-worn damaged valves --timing chain --water pump--pulley --really anything can cause a tapping noise --try to isolate the area or sound and diagnose problem

Can the tensioner make the chain to be loose inside the engine an cause it to make noise an show sign of oil on the dashboard?


A loose timing chain tensioner will not cause the oil lamp to light. The noise you are hearing is most likely valve noise due to oil starvation. The oil light comes on when the oil pressure is too low to be safe for the engine. Most people believe it is to tell you the oil level is low. A low oil level can cause low oil pressure is the oil is below the sump, but low oil is not the cause of the light - low oil pressure is. This can be due to a number of things, such as a bad oil pump, faulty bypass regulator at the oil filter, loose sump pipe connection, or even an oil gallery plug that comes out internal to the engine. You need to stop using the vehicle immediately and have the oil pressure checked with a mechanical guage to determine if the problem is the oil ressure or the sensor that lights the light. The chain tensioner being loose CAN cause noise, and that itself is an issue that should be fixed, as in many vehicles a loose chain can jump time, or jam and break, and since many cars have interference engines, either of these scenarios can cause severe internal damage to the engine.

How to tell if oil pump is starting to go out?


1. Engine Noise. With a bad oil pump sufficient engine oil will not get to all parts of the engine, especially the top end, and you will get engine noise with metal parts that would normally be lubricated and quiet knocking due to metal to metal contact. Engines with hydraulic lifters that become noisy can be a sign that they have insufficient oil supply. In addition to the hydraulic lifters, your valve train may begin to make noise if your oil pump begins to fail. Valve train components need to be properly lubricated as well. A bad oil pump can result in a lot of additional noise from your valve train system.

2. Higher engine temperature. Poor lubrication because of poor oil flow generated from the pump will cause friction in the engine and the engine temperature will rise. Good oil flow is essential for lubrication and reducing friction to a minimum.

3. Low oil pressure. The oil pump generates oil flow through the engine but tolerances between metal parts produce the oil pressure. Very worn engine bearings will result in low oil pressure. Thus a worn engine will have low oil pressure even though the oil pump may be fine and there is no issue with the oil pressure relief valve either. However you will also experience low oil pressure due to a failing oil pump because poor oil flow will also result in lower oil pressure.

If your oil pressure warning light has been triggered in your engine, the causes of the low pressure need to be properly investigated because the problem may not be with the oil pump. People replace oil pumps assuming that is always the problem and then still have low oil pressure because the pump was not the problem to begin with.

Oil light comes on and is dinging.


The oil light has nothing to do will oil level, but rather oil PRESSURE. If the engine oil is full and there is no rattling or banging noises in the engine, chances are the oil pressure sending unit is bad. If noises accompany the light, then shut down the engine and troubleshooting the engines internal lubrication system.

Low oil pressure light came on engine madee noise and died will not start but makes growling noise whe n trying to start


Sounds like you lost oil pressure and possibly the engine is shot due to losing pressure. It's possible the timing belt/chain broke. Even if this is this is the case, usually it requires valves replaced and head rebuilt/replaced.

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!

All the oil was sucked out of the engine into the radiator but no water went in the engine, is the just a head gasket or somthin else? i am a decent mechanic myself but i never heard of the oil goin into...


had lots of oil in my coolant when my saturn head cracked. Just depends on design--if there is high oil pressure near coolant passage. Is this a rotary engine? Overhead cam has high oil pressure in head...

Lifters making tapping noise. whats the cause??? 2003 mercedes sl55 amg. v8 kompressor


1 of two things. They are hyd lifters so there is no adjustment to be done. So it is either a lack of oil pressure or an odd thing but does happen, a small piece of derbis will get into the pressure bleed hole, the oil is push out as the camshaft comes up to open the valve, the lifter will collapes and not re-pump up due to the hole being closed off. Im quite sure AMG rquires Mobil1 oil, sometimes extream temps either higher or lower will change viscosity requirements. you may need the 15W 50 to maintain enough pressure where you are at or it is possible the oil is broke down so bad that it is no longer able to maintain the correct amount of PSI. 1st things first. Put a mechanical oil pressure gauge on the motor, observe pressure after complete warm up. If it is too low go to the 15W 50 weight oil. If it is an oil pressure issue two things should happen. 1 the lifter making noise should be farthest from the pump. If not you should do a very carefull inspection check psi with mechanical gauge 1st if it's low, then you'll have to find the causeor cause. if psi is within spec you have a bad lifter IE: dirt or collapsed spring.

I have a 1999 Beetle and When I'm driving My dash beeps like 10 beeps in a row and the inside lights come on but nothing so up on the dash to tell me the problem


Ok, so are you saying NO LIGHTS come on to tell you what issue is on the dash? The beeping you hear is a low oil pressure warning beep. Its telling you that you are either low on oil or that the oil pump is not delivering oil properly to the motor (car is sensing low oil pressure but on these cars there is no oil pressure gauge on dash to look at). Check your oil level and make sure you are not low. Best time is in morning on flat surface start car and let run 5 minutes. Stop car, let sit 5 minutes and then pull dipstick and check level. Also make sure you are using the correct oil and viscosity for this motor. VW's require VW certified oil and a certain viscosity. You can go to www.mobil1.com to find the correct oil available in the states for your vehicle. Too thin or too thick a viscosity could cause similar issue. Otherwise please clarify the light comment as I have never heard of the lights coming on automatically after a beeping noise and I will research.

Low pressure motor oil lumina 1991


Who has this on a board? Have someone check the oil pressure at the engine to see if your gauge is off. If the oil pressure is too low you may have connector bearings problems or main bearings. Suspiciion will be high if the engine has a lot of miles on it.
