Sounds like a bad rod bearing. Doing an oil change with halfway decent oil will "disguise" the sound but is still there. Check oil pressure when car is warm, if u are getting a low reading it's definately rod bearing (s). Car must be completely warm. Drive around for ten fifteen minutes, then check.

Tdi engine noise

If you drove after the oil change, I would kind of rule that out. There are many noises an engine makes and nine are good so you should be concerned about it. Bring it to another guy to check if you're not satisfied with this guy.

Knocking noise coming from engine changed oil and it went away for a month and now the noise is back.

Assuming oil pressure is normal, you could have a worn piston or bearing. Could also have a blockage in one of the passages in the crank or block.

I took my 2005 Dodge Caravan in for an oil change and it is making a knocking noise. I took it back and the mechanic said the oil pump went bad and now the van needs a new engine. Is this correct?

That very well could be-- if you lose oil pressure, this can ruin your engine. You should have seen a red "oil light" indicating that there was a serious problem, to accompany the knocking noise, which could be "rod knock" if you had very low (or no) oil pressure.
Make sure you have someone else verify before giving this guy thousands of dollars.

Oil pressure light on and knocking noise now

The light comes on when the oil pressure is too low, when the sending unit is bad, and, if you have too much oil in the engine and it whips the oil so much that the oil pump cannot pull the oil in since it is mainly bubbles

The knocking sound comes from a shortage of oil to he bearings, tapping comes from the valve train under the rocker cover (cylinder head).

Make sure you haven't lost any oil & that it isn't overfull and correct that if needed. Beyond what I've mentioned, you would be looking at the oil pump needing to be replaced or major engine repair if the bearings have spun or worn excessively.

good luck

Knocking noise from valve lifters , car was low on oil replaced oil will it correct itself

These engines were overhead cam.If you did put the oil back in as you said and the noise went away,no initial problem.The noise from the lifters, if its still there, is a ongoing problem.Maybe just an adjustment of the lifters needs to be done.Hope this helps

Have a 1990 Z71 4wd that with loud engine knock.

I'd consider some fresh, clean oil & filter change first of all, if it hasn't been done . drive it for a while providing it isn't too bad, & see if it goes away, if not get back to us.

noise is caused by lack of oil to lifters, or worn timeing chain. if noise is from lifters it should go away wit proper oil level, if still there needs timeing chain.

Knocking noise in the engine.

have you check the level of the oil... if it is down you are either dumping it on the ground (major oil leak) or it's burning oil quickly... i suspect if you ran it without oil the damage is done... either buy some stp oil conditioner (thickens the oil) or start using 50 weight oil.... all that will do is keep it quiet mostly.

one thing tho... don't try these solutions if you live in a cold weather climate... the oil will get so thick because of the cold you will have trouble turning it over.
