your problem may be lifters have picked up some carbon.

the use of the engine after it sat for a time may have caused this.

even though the engine has about 1000 miles on the install changing the oil and filter would be a wise action to take.

use 5-30wt oil with a high quality oil filter [NO FRAMS] .WIX ,PUROLATOR PURE ONE are an excellant choice.


before replacing the oil use 5oz of marvel mystery oil to the engine oil. give it a few miles to clean the carbon from the lifters. check to oil color if it turns black this is the carbon...If this action improves or eliminates the engine noise replace oil as above , and install 5oz of the marvel oil to remove any remaining slidge carbon..

post back how this all worked out ..
