1992 mercury topaz wouldn't start the fuel filter was changed and now when running the oil light comes on and sounds like the rods are knocking then will not start again could this be the egr valve any simple solutions?
It sounds to me like you've run out of oil completely. You may want to check that. A low oil light could mean you're low on oil. AKA you have less than 1qt left and that doesn't bode well with most engines. I wish you the best of luck with it though
You changed the crankshaft on a 1989 z24 but the knocking noise wont go a way you talked to a mechanic and he told you to wait until the oil goes back up three days pass and the noise is still therean?
The oil should be pumped into the oil journals in a second or two. If you still have rod knocking, you still have problems. It could be piston slap or any of a number of problems, but rod knocking is most common. Have you checked your oil pressure? If oil pressure is up when the engine is running and the knocking continues, it's not a crankshaft problem.
The Hummer H2 is a 2005 SUT with the 6.0L Vortec and a Magna Charger supercharger. It runs great with plenty of power, but I'm concerned about some noise I'm getting out of it. When I first start it up, everything sounds fine. After running a mile or so, I start to get a knocking sound. I only notice the sound when idling, not when running.
1996 Chevy cavilier z24 makes knocking noise when running could this be timing belt tensioner needs to be replaced?
You have 85 celebrity 28 carb loud knocking from lower engine loss of power oil changed regulary no leakage usage took oil cap off with engine running looked dry could it be oil pump or rod knocking?
The rod knocking is caused by loss of oil pressure. Did the oil light not come on? That light is red, red means stop. Do not start this engine again until the problem is corrected. You are probably looking at way more than just installing a new oil pump if the engine was run for very long without oil pressure. A complete overhaul may be in order.

Whats wrong when your car starts chuging and then making a loud knocking noice and it starts but makes those noices and shuts off?
Hard to say. If you mean it keeps running after you turn the key off it sounds like it's all carboned up. The carbon (inside the cylinders) gets hot and acts like little spark plugs and keeps the engine running and knocking a while. If it does this all the time I suggest you do a compression check to see if it has a bad timing chain.
