What causes lifter noise at start up?
Your engine can develop a sticky valve lifter or two due to several factors. They can create some nuisance noise because of the type of oil that is used, the type of oil filter, the condition of the oil pump, overall mileage, cam position on stopping, and even any recent work that involves moving them.
Why do my lifters tick when cold?
In the mornings or when the engine is cold, the oil has had the chance, due to gravity to drain out of these back down into the oil pan. When you start the engine when it is cold, this can produce a ticking sound as you describe. This happens as the lifters are moving without oil initially.

Many things can cause engine knocking or banging. Common causes are: carbon buildup in the combustion chambers or on cylinder walls, lifters or connecting rods, combustion timing out of sync, overheated engine, back pressure from the exhaust, vacuum leaks, fuel octane or quality, spark plugs, or knock sensors failing.
What causes cold start knock?
When you first start it in the morning, it takes a bit of time for the oil pressure to build allowing the oil to circulate properly throughout the motor. This can cause a bit of knocking and is somewhat normal as long as it does not last too long and is not excessive.

Why do Olds engines have lifters that are not adjustable?
The 1949 – 1964 early Olds engines use hydraulic lifters that are not adjustable. The 50’s Olds engines were notorious for flat cams,dished lifters, and worn rocker arms. Usually the lifters are the first to fail. One theory is that the cam lobes were too narrow for the amount of load from the valvetrain.
