Keep hearing ticking sound from engine change oil and went away but coming back

The TPS would be what I would do had that problem once myself solved the problem. as for the ticking noise sounds like a lifter is bleeding down as long as the noise goes away you will be ok. But may I suggest that if you are going to keep the vehicle for awhile longer you might want to have a set of lifters put in it.

The ticking noise could be a faulty hydrulic valve lifter. When last was the oil & filter changed, it coul be that the oil is thick and not going through to the lifters and when it warms up the oil is thin. It could be that the engine is need of an overhaul as 148.000 miles is 238.182 Kilometers and that is a hi milage.

Ticking sounds like a dry lifter, when was the last time you changed the oil and filter? Humming sounds like you need a tire rotation because of uneven tire wear.

might be the valves have been damaged running without oil
- or the crankshaft / camshaft / main bearings
most probably you have to let the engine be rebuilt by a mechanic
(expect cost of more than US$ 2.000)
or get another (used) engine at a scrapyard

Oil viscosity is too thin or broken down..Change the oil to a thicker grade.If the ticking persist worn Hydralic lifters or worn oil pump

Leaks will occur after a few years with any engine so repair them as soon as possible if its a large one

oil pump screen may be somewhat clogged

Definitely change your oil every 3 months or 3000 miles. After you change it add a half cup of Lucas engine oil suppliment when the engine is hot.
If if goes away you know it's cam or lifter issue. If it doesn't the ticking you hear may simply be your fuel system.

I would change your oil and filter ASAP and hopefully that sound goes away. If you are hearing the ticking around the throttle,chances are it is the lifters getting dry and that is why it's ticking. Do your oil change RIGHT AWAY and then stay current or you motor will be toast if it isn't already.

Good Luck

if this vehicle has a high millage then you have worn bearing if the oil pressure go's to low then this would be the problem, if not then you should have your lifters replaced but check oil pressure if the noise comes back when the oil pressure drops then you need to over haul your engine. if this information has been useful please let use know good luck

clean and or replace the terminal and sender for the oil pressure. they corrode pretty badly
