If you have a rod knocking, a new oil pump isn't going to fix anything. You need an engine overhaul, sorry.

Can lifters be replaced


Oh yea, lifters can be replaced , best if you replace cam an lifters together ! Loud knocking is not usually associated with lifters , they usually make a ticking noise ! Knocking noise is most usually in the bottom of the motor , main or rod bearings . most of the time rod bearings !

Hi, this is not the first time i've heard of this problem..I have repaired engines with rod knock, crank bearing knock and piston slap after these treatments. These products can clean so much carbon and varnish from the engine that it brings the real internal problems to the surface. Try using thicker oil

I have a 1998 GMC Sierra, when I start it in the morning it makes a knocking noise but once it warms up it goes away, what could be causing this?


We really need to know more about what kind of knocking you are hearing.

Pinging, clink clink, sounds like the time you got bad gas and put a strain on the engine causing it to knock. Airflow sensor telling the injectors how rich or lean to mix the fuel. Computer sets fuel air mix. timing , ect to match operating temp and if it is going bad throws the whole thing out of balance.

Ticking... click click click sound from the top of the engine that gradually fades,,( lifters on cam and valve chatter) sticking lifters can be treated with oil additive to clean them out if they aren't stopped up to bad. If that doesn't work or the noise keeps getting louder you need to have someone look at it or you can damage your cam or bend a valve and that can lead to a cascade failure of cam. lifters, valves and possible broken pistons.

Knocking. KNOCK KNOCK knock knock,from the bottom of the engine that fades ( rod bearing worn and slapping the crank til it gets enough oil to float it on the crankshaft or crank bearings worn and bearings trying to spin in the races)
If it is a hard knock could be a worn rod bearing or a partially stopped up oil port in the crankshaft that doesn't let the oil do its thing until it is warmed up. This problem can be slowed down with cleaning additives but the damage has already been done and will do nothing but get worse over time. If it is a bottom end bearing don't let it totally fail. If you have a mechanic you trust get him to listen to it and help you figure out what needs to be done. Once you have heard these noises and have someone point out the differences you don't forget them.
Remember. Sooner you get this figured out the less damage done and the cheaper the repair bill will be.

My 89 chevy is making a knocking sound i just replaced lifters,push rods rocker arms timing chain and gears cam and valve springs and umbrella seals. i have no clue what it could be except mabe the timing


Did you check the knock sensor located on the passenger side of the block, behind the starter, The sensor can be bad sending a signal to the Computer causing the computer to readjust the spark advanced timing causing Knocking and pinging....... or it could be as simple as bad gas. If you changed the timing chain, the gears should both be set with the the timing marks at 12 oclock for the 89 chevy K1500 5.7 350 V8 TBI OHV 16V if you set the timing at 12 oclock on the cam and 6 oclock for the valve and Distr. the number 6 is firing as number 1 you can recheck by bringing the No. 1 piston back up to TDC and check to see if your Distr. is pointing to the No. 1 Plug Hope this helps

96 Suburban v8/7.4L/454 K2500, Knocking Noise??


sound like an internal engine problem. either one or more of the pistons has "piston slap" and that knocking will diminish as the engine warms up or possibly a rod bearing is worn out. have a tech do a manual oil pressure test to make sure the oil pump and main bearings are ok. piston slap or knock that decreases when the engine warms up is not that serious, but a rod bearing knock or possible oil pump failure should be taken care of asap.

'99 jeep grand cherokee v6 loose rod in engine


Likely you need more than one (not rod, but rod bearings) In most cases you get knocking noise and low oil pressure as symptoms. If caught early you can do this in-car otherwise engine needs crankshaft and all bearings as well as new pump and system flush.

High oil pressure and knocking in the engine


There is a pressure relief valve in the oil pump, it is stuck closed, this happens now and then, seen it 2 times, since the oil pump is a positive displacement pump it can produce 100's of pounds of pressure, the reason for the noise is that u have allot OF pressure but very little volume, the bearings are being starved for lubrication, replace the oil pump, DO NOT DRIVE THE TRUCK, U WILL BURN OUT THE ROD AND CRANK BEARINGS.
