I have a head laying in my garage and I was wondering if i could adjust the valve lash b4 i slap it on the block or does it have to be on the block in order to do it?

anyone?

 

You should be able to do that, if you figure out how to handle a couple issues.

Lubrication while you're turning the camshafts?
Support the head without scratching the headgasket surface or obstructing the action of the valves.
Make sure you return the camshafts to #1tdc before installing onto an engine.

You're SUPPOSED to adjust valves with them at room temperature, so that part's good.

 

I can use oil or wd40 for the cams right? any other special instructions i should follow?

 

i dont think that wd-40 is good enough i could be wrong...id use 60w motor oil...are the cams in or out of the head

 

in.. could i take them out then do the valve adjustment?

no dont do that...the whole point of a valve adjustment is to adjust the clearance between the camshaft and the lifters....the only reason why i was asking if the cams are in or out was because if they were out just apply assembly lube before puttin em in...

 

ohh ok.. should i apply it all over the cams?

 

only if the cams are out and ur putting them back in...if ur gonna disassemble and reassemble just for learning sake...yeah id put it on the cam lobes and lifters between the head and the cam cradles..pretty much anywhere that metal to metal contact occurs...good luck

 

id do it with the head on the block. Your going to find that the cams are going to want to wander without the tension of the timing belt on them. Plus to do it properly your going to have to install the cams then take them off to install the head then reinstall the cams again. Too much work.

I cant slap on the head with the cams already installed?

 

how are u gona torque it down with the cams in it...u have no access to the headbolts

 

to save time i would do it when the head is on the block. This will be easier to adjust and make sure that the clearance is correct.
