no problem it clamps around the small lip there at the end of the pulley then threads in and pulls the pulley off the shaft - the pulley is pressed on.

It's nothing more than a P/S pump pulley puller/installer. Say that 3 times fast.

DO NOT be tempted to use a 3 jaw gear puller. :tisk:

Yes, that's a P/S pulley pulled/installer.

What gaskets are you trying to replace? If its anything more involved than the cam cover gaskets, throw the Haynes out and get a real Helm FSM.

Actually, do that anyway.

Just doin cam cover for now that's all I feel comfortable doing on my own but your sayin the Haynes one is garbage, it was the only one I could find and get today I'm a newbee

Thank you guys for all the help, blessed me really couldn't find any info for days from any parts store clerk

Haynes and Chiltons are way too vague, la k way too much info, and sometimes just plain wrong. Best used to soak up spills or line bird cages.

You can get a Helm FSM set (not just one book) used on eBay, or new on Helms site.

NEVER ask a parts store clerk for information.

Either find a used GM/Helm service manual set on eBay or new at www.helminc.com. (A new set is now over $200)

Or subscribe the car (multi-year) to www.alldatadiy.com - cheapest of all ways.

I got the tool and removed that darn pulley but now my head is completely unbolted but still won't come off dew to the rod that the pully was on. Any help please

The "rod" is the left bank intake camshaft. You need to remove the intake cam oil seal - at the pulley end - and work the cam cover off the head. New seal, or you'll have a heck of an oil leak.

You NEED to get a real GM service manual. Too easy to break something costing big bucks.

Wait until you start on the right (rear) cam cover.

The removal procedure assumes that everything is out of the way of the cam cover - hoses, belts, pulleys, belt tensioner, everything.

As posted, you'll have to remove (and replace) the camshaft seal.

How do I "work" the valve cover off

----------

Valve covers wedged on there do I have to jack the front side of the motor??!?

Submariner409

Is everything - EVERYTHING - out of the way ? All hoses, radiator cover, belt tensioner, w/p belt, cover, everything.

No, you should not need to lift the engine - and if you do, you'll need jackstands to hold the car and then remove the front motor mount.

I can lift the cover all the way off on the one side (over the chain on the inside and everything) then when I go to slide it off the rod the covers not moving at all

Have you removed the cam extension oil seal as shown in Post #14 ?

Buy a new one for the replacement process. The original WILL leak like a sieve.

It takes the removing of the bolted on cam seal to gain enough clearance to work it off the end of the camshaft "That rod"

He did that since Post #14 and #17, verified in #22

Can you work the cover back into its original as-installed location and begin again with the oil seal removed ?

I see where you told him but didn't see any response where he did it. All he can talk about is having his head unbolted and that darn "rod"
I think he needs to bolt his head back on so he can think and do as suggested and remove the cover.

I can put the cover on its stuck though when I try to lift it off like post #16 but it will not slide off

If the cam cover is off how about - Is the belt tensioner for the water pump still in place? Did you get the valve cover bolt that's hidden on that side? Is it getting stuck on the oil dipstick or upper radiator hose? Those are the initial items in that area that come to mind that you might be fighting against.

Thanks for the reply I have everything out of the way the cover seems to get wedged by something under it on the right side near where I took the pully off when I lift the left side over the chain then I can't slide it

Have you tried rolling the engine over a little. you may have a cam lobe interfering with it.

There's nothing else on that side of the motor only thing under the valve cover is the 2 camshafts. there is a camshaft cap near the end there where the shaft comes out but that should have no bearing on the valve cover removal. any chance you can shoot a quick video of the issue and post it onto YouTube so we can see visually what your having an issue with - just post the link here. Is the valve cover completely loose before you go to move it can you move it feely before you go to slide it over?

If that's his picture and those are his yellow arrows, it's a pre-2000 engine, but there should be no difference in the removal sequence.

I wonder if the spark plugs need to be removed.

Good question. I can't imagine anyone trying to remove the cover without removing the plugs.
Shure wouldn't go endways with them in.

I did not snap this shot, found it online... My cam covers just the same molding as the one pictured (pre2000)... Of course u need to pull out the plug wires, but the actual plugs set down that there's no way it's gettin stuck on them.
I don't see the word deville in this whole thing till u said it lol

With the cam sticking through the cover there is no way you can raise it enough to clear the plugs so you can move it endways. SHEESH!!The plugs sit in a tube that is cast into the cover.

That one is a bit tricky. Do you have that gasket off on the end of cover? Remove that, it may give you a bit of extra room.

If I recall, when I took mine off, I lifted it up a tiny bit, then slid it over to remove it. There isn't much room to do it, as it is a tight fit, but I can assure you I did not have force anything. Kinda like a rubics cube, it will come off one way or the other with little force.
