installing cams = removing head?

**Ghost** · 26-10-2005 08:59 PM

Just wondering if its an absolute necessity for the mechanic to remove the head in order to install valvesprings?

is it possible to install while the head is still on

yes otherwise you will have valves falling into your cyclinders.

You don't have to have the head removed. Rotate each piston to tdc when doing the corresponding valvesprings. I had ctr cams installed and my head wasn't removed...

Correct, we did the Turbo EM1 (feature car) this way.

It gets VERY tiresome, especially when installing dual springs, i dont recommend it.

excellent...thanks for that guys

i dont want to remove my head for a few reasons

1. new headgakset
2. with head removed i'd be pressured to do a pnp
3. with head removed i'd be obliged to rebuild botom end

is it the same amount of time involved with doing it with the head on?

and also if a valve does drop... does htat mean off comes the head or can u pick it back up?

you can also use compressed air or rope inside the combustion chamber to hold the valves closed.

yep. compressed air. they make adapters that screw into the plug holes.

I'va heard of using compressed air but never knew how it was done, cheers for the info

rope is easyer and simpler,

less farting around and lees posibility of some thing going wrong.

like proecu says, double row valve springs will take time, but I have done heaps of single row springs and valve srem seals useing the rope method. Id much rather do that even if it takes longer to do than taking a head of for no reason. its all about cost.

even if the head was off, its still a pain in the ass to change springs on some heads.
