Hydralic Valve LIfter Problem

Posted by fainacci556 On 2022/8/22 10:08:58

Good morning- I hope you knowledgeable guys can help me. I have a very nice 1955 400 I just got. The car was beautifully restored and the few leaks it had were fixed. I understand these engines were prone to a valve lifter noise and mine has it, especially when the car is run on the highway and is hot. When it is being driven local the lifter noise comes and goes. The engine has plenty of power, uses no oil and the drain oil is pretty clean. I tried the remedy of using a heavier, 15-40 oil and STP but it does not help. I'd like to avoid tearing down the engine. If I run it the way it is will I damage something? Please advise and thanks
