Hey guys,long time no see.anyways got a stock lt1 60k 1.6rrs.
after it sit for 3 or 4 days,it will make a strange noise on start up.
it fires right up,and woooshing,for about 5 seconds like a vacuum line is off,sounds like air wooshing its constant, then fades away. not pidder padder like exaust leak.
Im thinking lubrication,maybe the oil isnt on the rockers yet???? it sat a few days and the oil has to pump through the push rods to get up there??
but I really dont know so im asking.
