Engine tapping and stalling

I lost my job so I haven't had the money to change my oil. My car started running really bad so I added 3quarts last night. This morning on the way to work my car was struggling to switch gears, still tapping and now stalling out on me. Did I kill my car?

    Is it missing any? Some vehicles if the oil pressure is low they will refuse to run in order to save the engine. Check the pressure and think about maybe changing the sending unit. It is possible you damages the cam or the vavles are sticking. Please clarify as to what engine you have in it. If its what I think it is you could have damaged the lifters if its a push rod engine. Get a helper, and take one of the valve covers off. Have them start the engine while you hold the valve cover over the lifters to make sure oil doesn't spray you. Listen to the lifters. Also before you start it, try to spin the push rods. If they are lose and move easy then you messed up the lifters and just have to change the lifters. Won't cost an arm and a leg, but your looking at $10-20 each and there is 12 on the car, so depends on how many broke.

Car wont stay running unless foot is on the gas pedal


is the CEL check engine light out running? (it comes on stalled, and is normal that)
stalled. engine stall. no year, now that makes this 10x impossible
and even more impossible no engine stated, (displacement or VIN)
F22? 2.3. 2.7? 3.0L?
if in usa, (no loctation stated ) open hood, look up, see tag?
see vacuum EPA map, see engine type? bingo.

so I wall answer in the generic, (ALL CARS gasoline)
fails hot or cold engine, does hot engine reach 180F and hold?
wow, how low was the oil, off end of stick, none?
stalling is caused by over 50+ things. (we do tests to find it fast )
we use tools, do you have tools, or can buy them, or do you just want
endless guessing. here is the path.
#1 stall maker is a stuck open EGR main valve, ignored during the turn up, clean it. make sure it close
in the macro,
1: bad engine, the hot engine can lose compression and stall.
tool1 the $20buck compression guage.
2: bad spark, or timed wrong. gapped plugs wrong, wrong plugs used. bad wires sets, (old dizzy engines) bad COPS newer cars.
check for hot spark at all spark plugs, skip none.
3: bad fueling (too much or not enough
if engine runs perfect and only idle is too low 800 hot is normal
no DTC 300s misfires, then maybe the ISC is just dirty.
we clean the EGR and ISC every time.
if the EGR leaks, the fast right foot can save a stall but is hard.
if the ISC sticks closed, saving the stall is piece of cake, super easy
after all , you are adding the missing air.

does that help,. no, then take it top the man, the ASE man.
The Mechanic.with the ASE patch on his /her sleeve.
no year, ouch.

2004 Navigator 5.4l dohc passenger side lifter tap.


Are you absolutely certain the noise is lifter tap and not an exhaust leak? These are pretty well known for breaking exhaust manifold studs, or even cracking exhaust manifolds. The noise will be present on a cold engine but might go away as the engine heats up and the manifold expands. Maybe that's why it seems to go away after adding additives or changing the oil. It gets just enough heat in the engine to fool you in to thinking the issue was resolved by adding the oil/additive. Are you always adding to a cold engine?

A ticking sound on a 06 ford f150 super crew 5.4L


Ticking sound could be coming from a Coil-on-Plug, or a pcv valve, or (hope it's not) a valve lifter which could be sticking. Sticking lifter noise often disappears when rpm's change, or the noise comes & goes. try changing the motor oil & filter right after adding an Engine-Flush Treatment to the motor oil, running the engine for 10 minutes at idle with treatment added to the oil, then draining the oil & changing filter while oil is still very hot. That last part is very important, so be careful not to burn your hands - be careful. -- The sticking lifter is a likely cause if motor oil has not been changed at frequent intervals in the past (every 3-4K miles) -- dirty oil causes sticking lifters.

You need a valve job and probably the bottom end done also. it runs crappy at first because the cylinders are full of oil from the valve seats leaking after a while you have burned this oil and it runs better, Don't waste you money on an ECM. Broken valve springs , leaky valve seats, if you know all this you should know you need to rebuild your engine and stop wasting you money, by hoping it's something else. I'd sell it and just by another low end driver, because it isn't worth the repairs.
good luck

What can cause a knocking at the right hand side valve cover


Hi , usually a knocking / pinging from the valve cover indicates a lifter tapping. Could be worn out or just worn. Do you change your oil every 3000 with high quality oil? (I always have used valvoline standard with outstanding results) Dirty oil and filter and or incorect weight oil and or using synthetic oil in older cars can result in lifters tapping. If your oil is under 2000 miles since last change and you used a high quality oil (watch who changes your oil, some places use inferior oil because its cheaper) you can buy a pint of oil treatment formula to quiet noisy lifters to coat the lifter and quiet it down. It is a sign of engine wear, but one lifter tapping a bit wont really hurt your engine mechanically. If they all get noisy, time for a valve job. Root cause is wear due to insufficient lubrication. The lifters on newer cars are all hydraulic and they self adjust. No manual adjustment is possible. Bottom line: keep your oil changed regularly using a high quality non-synthetic oil for your 1999 vehicle.

BAD LIFTERS WILL MAKE A NOISE.IF VALVE LIFTERS AND LOWER SPRING SEALS BEEN REPLACED AND LIFTERS STILL NOISEY.EITHER ENGINE OIL TOO THICK OR ENGINE NEED OIL CHANGE + FILTER CHANGE.DIRTY OIL CAUSE LIFTER NOISE OR OIL PASSAGES IN THE CYLINDER HEAD STOPPED UP NOT ALLOWING LIFTERS TO GET THE RIGHT AMOUNT OF OIL.OR OIL PRESSURE TO LOW DUE TO FAULTY OIL PUMP.OIL PRESSURE SHOULD BE 29 PSI @2000 RPM. TRYING ADDING SOME SEAFOAM CLEANER IN CRANK CASE IF OIL PASSAGES STOPPED UP IT WILL CLEAN OUT OIL SLUDGE.GO TO AUTO PARTS STORE TELL THEM YOU NEED SEAFOAM.AFTER 500 MILES YOU NEED TO CHANGE OIL AND FILTER AGAIN. SEE IF THIS HELP BEFORE SPENDING ALOT OF MONEY .
