Remove the valve cover and rotate the engine and check to see if all the valves are opening the same amount. If not, you have either a bad lifter, bent pushrod, or cam going flat. Check your valve lash with the valves closed. You should be at 0 lash at all of the rocker arms.

My acura is making loud banging noise from front when idling. sounds like a missing spark plug but all spark plugs are fine. what could it be?


Can be a lot of things.

Could be a bad rod or rod barring.

Could be a clearance issue in a rebuilt engine.

I wouldn't run it until you Take it to a shop for diagnostic.

97 expedition 5.4 doesnt idle very good


Surging idle is usually caused by vacuum leaks. Ford 5.4L engines are notorious for the PCV hose elbow leaking back behind the throttle body.

The PCV tube goes from the right (passenger) side valve cover and loops around behind the valve body. Inspect this hose on BOTH ends.

I have a 2003 Chevy Impala. I ran my car with no oil and now I'm hearing a loud ticking/knocking noise coming from under my valve cover. I added 2 bottles of oil after finding out that I didnt have any...


might be the valves have been damaged running without oil
- or the crankshaft / camshaft / main bearings
most probably you have to let the engine be rebuilt by a mechanic
(expect cost of more than US$ 2.000)
or get another (used) engine at a scrapyard 2003-chevy-wutfveiel3ypko01ydor435x-5-0.jpg 2003-chevy-wutfveiel3ypko01ydor435x-5-2.jpg

Reverse went out on 1978 Chevy pickup


Nothing. Also it will be much cheaper to find a used matching transmission with low (less than 80k miles) than having a shop rebuild the old one. In most cases the used transmission will far outlast the rebuilt one. Check on the web by Googling "used transmissions".

5.3 chevy loud hammering noise


My best guess is that you might have thrown a rod. You will experience a great loss of power, and if you were to drain your oil, you would notice a decent amount of metal chunks. Generally a light tapping noise is uncommon for a engine with 80k, but depending on how well it has been taken care of (ie. oil changes, high RPM, low grade fuel) it is possibe to damage an engine with that low mileage. You would be better off taking your vehicle to a reputable mechanic that has access to rebuild parts. Good Luck.

1997 Mazda Protege: Engine has clicking noise when idling.


Check to see if the valve lifters are not making the noise. Turn on the engine and rev it up to about 1500 rpms and see if the clicking is coming from the valve cover area.

Check Utube for lifter tap, valve tap, and rod bearing noise. If you pull each spark plug one at a time, plugging it back in after each one, the tapping will go away if it's a rod bearing. At any rate, on your next oil change add some valve-medic or similar additive for valve noise. Make sure you follow direction or you will get massive lifter tap if you pour it into a cold engine.

New rebuild chatters


adjust your valves your oil pickup tube needs to be adjusted you need feeler guages to adjust the valves down properly
make sure lifters and oil pick up tubes are not clogged

feeler guage is---> thin pieces of metal cut to different sizes to hold under valve adjusters till the play and chatter gone
check by book what the feeler size needed for adjustment
