Valve lash cold/hot
 

I have a new to me 582 -- the builder says valve lash is .016 hot. My question is...

I am changing the lifters= I have a Jesel setup-- so i have to remove the assembly... now when i put it togther i want to lash it somewhat close being cold.. as i cant start it yet ..im waiting on some odds and ends but i would like to have it close.. What should i set the lash at cold if the builder has said 016 hot?

Thanks In advance
Keith

Question, does it have aluminum or cast iron heads?

Close is about all your gonna get till you can figure out just how much growth your dealing with.

I would to set them all on .011 to 010 cold.

Start it, let it get good & warm, re-set them 'hot' let it cool, check again.
Make note of the lash 'cold' - then you you can set them 'cold' all the time.



On my motor, BBC 496 W/ cast iron heads.

I set all mine @ .022 cold, calls for 28 and 30 hot, never had any issues.

I am a knucklehead... the lash number is 026 hot... i dont know where i got 016...sorry

The are Dart 360 aluminum heads .

Thanks
Keith

set them at 23-24

Mine I set cold at 23 and they are 25 hot alum heads

I set mine at .016 cold and they are around .021-.022 hot. Iron block aluminum heads. BBC.

I sure hope this doesn't turn into another 'valve lash' thread.LMAO

Tell me EXACTLY how to adjust my valve lash. :lol:

Well Tod first you remove your valve cover then... :lol:

Mine are .26/.26 @ op. temp. Sorry guys, but you know I am learning too, so here is what I do not get: If metal EXPANDS when hot, why is the lash LESS cold? If metal expands, should you allow for more LESS lash when cold? I don't get that!! Should the heat provide less tolerance in itself? For this confusion/reason, I never set mine cold. Until I understand this, I will not take a chance.

Wish I could help you here scooter, But i've been setting my lash, the WRONG way, for forty years.
