Just fired up new redtop, awefull noise.

[DTS]

So i just replaced my blacktop with a redtop,

the motor has 155 compression across the board, and my guess is it has been sitting for a good 10 years..

so i primed it, fired it up, fired on the 3rd crank, however there is a terrible sound comming from the head like

TICK TICK TICK TICK and it does not go away with rpm, when the engine is reved up the ticks just happen quicker but the sound does not get higher pitched..

i let the motor run for about 30 seconds to see if oiling would make it go away but it didnt seem to help much.

however on the plus side the motor seems to run well and idles smooth.

im thinking its most likly lifters that need to be bleed since they probobally ran out of oil from sitting so long?

or do you think the oil pump is dead and not supplying the head with oil?

any imput guys any help is greatly appreichated!
