What causes valve train noise?
When the sound is throughout the entire valve train the cause is usually; the weight of the oil or the oil supply itself. Too much oil in the crankcase will cause, foaming and aeration. Excessively thick engine oil will cause, entire valve train noise, when cold-starting an engine.

How Much Does It Cost To Fix A Valve Train? You can expect to pay between $900 and $1,800 for a replacement after replacing your vehicle’s make and model.
Will seafoam quiet noisy lifters?
Sea Foam works to dissolve and liquefy petroleum deposits that grow too big and sticky to drain. Use in gas or diesel oil crankcases to safely clean and quiet noisy lifters, cleans chain tensioners, actuators, VVT solenoids, oil control rings, and cleans out oil passageways.
Does lifter noise go away?
This happens as the lifters are moving without oil initially. As the engine warms up and oil circulates back up to the top of the motor where the lifters are and they begin to pump up full of oil, the ticking sound should become lighter and eventually go away.
How long does a valve job take?

Why are my valves rattling?
One common problem that will cause a rattle at idle is a failing hydraulic valve lifter. The lifters are small parts that open and close the engine valves, activated by oil (hydraulic) pressure. If you hear a “clack-clack” kind of rattle when you start your car’s engine, it could be a sign of piston slap.
Why are my valves ticking?
The most common cause of engine ticking noise is low oil pressure. Your engine may be low on oil or there could be a problem inside the engine causing the low oil pressure. Ticking, tapping, or clicking sounds can also be symptoms of worn valve train components such as lifters or cam followers.
Can I drive with noisy lifters?
Do not ignore this sound because the damage from this ticking noise can be big and expensive. You shouldn’t drive your vehicle for more than 100 miles if you have bad lifters.

If the oil is dirty, it can also cause valve sticking and cam lobe scoring. Change oil and filter immediately and see if the noise goes away.
What causes a valve train to make noise when starting?
Insufficient oil supply to the lifters can also cause, general valve train noise. This could be the result of too little oil in the crankcase; an oil pump not operating properly or clogged main oil gallery lines. Excessively thick engine oil will cause, entire valve train noise, when cold-starting an engine.
What is the frequency of the valve train noise?
The sound frequency of the valve train noise is, one-half the crankshaft speed. A clicking lifter is one, very common, valve train noise. Also, if the engine is equipped with solid (mechanical) lifters fixing this usually requires, an adjustment.
How do you fix a noisy hydraulic lifter?
If the noise stays, you may have a defective hydraulic lifter or cam follower that needs to be replaced. Turn the valve spring half a turn with a wrench.
