SOURCE: Ticking Noise in 01 Chevy Silverado 2500

if noise is higher pitched and coming in on valve time...(2wice for every revolution of motor..ie: faster)...then upper end pressure is down due to sludge, wear , lifter failure, valvespring failure,rocker stud lifting out of cylinder head (kinda common) cam bearings failing (very rare)..oil pump bypass stuck open..and a few other possibilities... respond and we will go over lower end sound (deeper ,slower) and see what identifies your issues .... miles

SOURCE: I HAVE 02 TRAILBLAZER LTZ, AND IT JUST STARTED

Hello, I see you have a trailblaber with a knocking noise. It sounds like you have an electric fan clutch issue. Believe it or not your vehicle has an electric fan clutch. It looks just like the older non-electric but if you look on the driver side of the fan shroud that is the wire connector you see. It is an exspensive part just for the clutch but thats exactly what you are describing. It doesn't get louder just fast with rpms. Please rate my answer, Thank you

SOURCE: suddenly running rough

Well, it could be a couple of different things. The "jump timing" theory would have a poor engine performance and engine miss associated with it. So I don't believe this is the problem.
If the ticking or knocking sounds like it is coming from the top of the engine, you have a clasped lifter, bent push-rod or rocker arm problem.
Is the noise present when the engine is cold or hot?
Make sure the oil does not look milky.
Let me know.
Regards,

SOURCE: 1998 s10 oil leak

well it wont be the oil pan seal then cause they never leaked that much. I would go back and look at the filter he put on. could be just a problem with it. for the cost of one put another one on and make sure the gasket surfacce is clean down to the metal engine block.

SOURCE: oil pressure drops to 0 at idle

OOO not good sounds like some of the head gasket got stuck somewhere, or the gauge or sender is bad or got knocked around when repairing the head gasket. I would check that first. If that checks out will need to drop the pan to see if something got stuck in the pickup tube,might as well change the pump while you are there. Or worst case some thing wrong with gasket job impeading oil flow back to bottom of the engine. Was the oil and filter changed ?if so pull out filter and see if an chunks are stuck in it now. And change oil and filter again. Sorry that was out of order I had a long day

Honda passport problem


The louder noise and burnt smell possibly was the bearing getting worse, or going out, causing the belt to slip over the pullet and start heating up.
Was it a burnt rubber smell?

I don't see how this could have anything to do with the flywheel though.

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?

I've got a slight ticking noise, but not at start-up. After the engine warms up, it will start out very faint and gradually get louder. After about 2 - 3 minutes, it goes away. This is a High M


This sounds like a tappet (cam follower/rocker arm) is at max clearance. This can be the sign of cam lobe wear or follower wear on its internal clearances or valve tip wear.

Cracked oil pan on 05 pontiac g6


The car could have hit something on the road that made contact to the oil pan, or if the crack come form the inside the engine. It could have internal engine damage. The best thing to do is to just replace the whole engine with a rebuilt and you'll know that your going to have warranty and have the car for a long time. Good luck and hope this helps.

Car overheated and knocking.changed rod bairings.good to go. now


99.999% of all spun bearings cannot be replaced with any expectation that the problem will be repaired 1. debris from the old bearing enters the oil port on the crank and will damage the new bearing as well as others. 2. damage to the crank itself must be precisely machined to exact size and concentricity. Most crank pins are too thin and will become egg-shaped after machining and re-use.3. even replacing the crankshaft without flushing the entire oil system is a gamble. Waste no more time or $ on this and either get another engine or different vehicle.
