I would not worry to much about this noise when the motor is cold; engines have clearanaces that come together at operating temperature. If this noise happens when the motor is at operating temperature then you might have a problem.
It sure can.
Rods and Rocker arms were the problem with my Malibu after changing lifters
The most common cause of lifters knocking is low oil pressure.
Exhaust leaks, bent pushrod
Could be, Out of adjustment Worn camshaft Worn lifters Worn pushrods Worn rockers All of the above.
It sure could. If you KNOW how to use it and READ it.
A bad fuel injector poppet could cause that.
it will cause the engine to overheat and also coolant to enter the oil system, which will in turn cause wear of the lifters.
Not if the are the same fitting wise and gaskets are used if necessary. There could be differences as the vortec is designed differently.
low oil pressure could be one cause cold oil is heavier in viscoity and as it warms it gets thinner, the lifters are not getting the oil inside of them causing them to colaspe try having a new oil pump installed
Low fuel pressure, bad IAC valve, vacuum leak, bad injector(s). You also need to check the EGR valve.
the iac is controlled by the computer and adjusts the air flow needed by the engine, hence idle air control. if the iac is defective and does not seat properly, it will cause a high idle
Lifters dont really knock, they chatter. You may have a bigger problem.
Yes. It is very common in weight lifters.
It has both.
Although there are several things that can cause this code. The most common on the vortec is a bad distributor cap. When you replace the cap. Do NOT use a cheap cap and always use ac delco plugs in a vortec. They are very picky with ignition. If you need it timed afterwards you will have to use a scan tool and set it plus or minus 2 degrees of 0 while watching the cam retard on the scan tool.
Yes, roller coasters can be very bad babies and can result in injuries and death.
A bad fuel injector poppet, a bad spark plug, a bad spark plug wire, a bad distributor cap and rotor.
A spun--Bad rod bearing. NO OIL PRESSURE.
the roller coaster freak Marcus delo; the carts cause the're always together
Honestly yes. it can cause major problems and all together it could cause your engine to blow. so id change them they arent that hard.
