I posted this up in F/I but i figured all motor guys might know this sound better.

I have already redid my valve lashes

I cranked it over with no ECU for over 10 times and there is no sound

No CELS

checked if i left anything in the valve cover

Bottom end is BRAND NEW 0 miles built by a very reputable builder

When i pulled the head off 3 months ago i pulled it running 100%

Timing on crank/cam is right on point

at this point i am completely baffled motor starts up basicly right away

y8 head:
crane turbo cam
crane springs/retainers
oem valve 3 angle valve job
crane cam

y7 block
aebs sleeved
cp 9.1 piston
eagle rods
crank micro polished/balanced
acl bearings

is it comming more from the top end? did you check the clearance between the head and the cam? also how are the lma's

so far we think its coming from the head.

head and cam? or head and block? i didnt do that. block has been milled .015 head had been decked before not sure how much.

the LMA SEEMS fine how do i check if its ok?

 

push them and if they stick on the rebound their bad. what i meant is on some D cams ive seen the vtec lobe is to big and hits the galley it runs in, ive had to grind some out of heads to get some cams to work.

 

mine are pushed in do i just use a socket or something to push it in further?

the y8s are like this

 

if i remember correctly the y8s have the lma's on the forward side, not 90'd like the z6's.
