Here is a movie of what the noise sounds like. Yes it quicktime, its the only format i could do

http://home.comcast.net/~linda...4.MOV

I just replaced all my LMA's today, the new ones are in in this video, 8 ITR LMA's, we checked my valve clearance, and adjusted what need to be.

THIS IS BAFFLING me i how no clue what it is, its not rod knock because it goes away at high rpm's and it changes pitches, well it sounds like it to me atleast. car still pulls fine. compression tested at 200 across.

PLEASE help me figure this out before i encur any long term damage. Or do i just need a buy a new head?

TIA
Matt

edit: its the fast paced ticking noise i'm wondering about.

 

curious, is the valvetrain oem... any work done before?


that is really loud. sounds like valve clearance but hard to tell without being there in person to listen.

 

valve train is all stock, SIR 2 b16a cams, new intake valves on #1 piston, had new seals cut and new guides. someone stated to me it was valve tap. Is valve tap bad for the motor? will it hurt the longevity of the motor?

 

Wow.. that's loud!

 

when did the noise start. important details are crucial to any diagnosis.

 

Went on a trip. 400 miles each way. I started hearing it on the way back when i was no more than 20 miles from my house

 

Are you sure its not the voice of satan?

 

Im no pro, and this is a guess, but do the cam caps go with this head, maybe there is some play in one of the cam shafts. Just a thought and I'm probably way off.

 

I have the same problem.... any news?

 

any news?

Here is the low down of what happened with me.
I HAVE NOT PLACE THE HEAD BACK IN THE CAR YET SO I DON'T KNOW IF THE NOISE IS GONE.
I had the same noise that you guys have been hearing in my car for a while so I asked my machinist to replace the valve guilds. When he took my head apart he found that: 1. all my valves were bent and twisted (therefore not seatting properly). 2. most of my valve guildes were cracked or broken.
I had bought the head from a friend without known what work had been done, or what was wrong with it. Needless to say I have had to replace all the valves, the guilds and the valve seals. I will let you know what happens when the engine is back in the car.

Got my head back and have it installed. The car is so quiet now and drives like a dream. The only noise that i heard is from the injectors.
