@DenLorsTools Do I need to rotate the engine at all to avoid any damage when using this tool?

[DenLorsTools]

@rredd47 Good question, this is covered in our repair article. It may be necessary to turn the engine a little if you you have difficulty getting enough room to remove any of the pushrods. Some guys don't realize this, force the too much leverage on the tool and can actually break the tool at one of the welds. Thanks for the question and good luck.

I have a question. I recently did this work on a 2003 Malibu. Why did you not pull the valve covers? The gaskets have to be changed anyway. I like the tool though. Please respond.

[DenLorsTools]

The front VC is removed during this job. The rear VC does not have to be removed to change the intake gaskets (this saves time by not removing some of the components) You can change the rear VC gasket too, if it's leaking. The tool allows removal of the pushrods so you can replace the intake gaskets (the pusrods go in betwen the holes of the gaskets). The pushrod bolts are threaded into the aluminum heads. It's best to avoid working those threads if possible, they strip easily. DennisB

Thanks, I know that the rod guides are there, but I like the tool, nice to have next time.

[DenLorsTools]

@caddop22 Yes, the guides for the pushrods are built into the intake gaskets. And yes, the pushods are different lengths for intake and exhaust. I know you've already done at least one of these jobs and you are aware of this, but I mention it for other guys that may be reading this prior to their 1st job of this type.. I also recommend using a Lisle LIS24610 funnel to help fill the system with coolant after the job is back together. This helps to get the air out of the cooling system. DennisB

If you've done enough of them, the extra time to remove the coil and rear valve cover is miniscule. Not to mention the fact that you SHOULD be replacing valve cover gaskets doing this job. The people are paying for it to be done, corners should not be cut.

[Mikeyssss]

oh yea, it would make no sense at all, if you already have the intake off, y would you do just one gasket?, i mean i cut corners, but theres just some corners you dont cut

do you know of any one that makes an alloy intake manifold for the 3.8L. The closest I have found was the W body store, they have a fiberglass reinforced intake manifold

[midgetmayo]

I didn't use this tool. I just cracked the bolts on the rocker very slightly then just squeezed the pushrods out. Then used an egg carton so I could remember where each one went.

@chrisfrisina

Did you make sure the Coolant system is completely bleed of all air? Is the thermostat ok?

[caddop22]

@DenLorsTools

Ok, thanks man. I do wish I would had that tool though, instead of taking the valve assemblies loose and then having to make sure the pedestals were lined up. I understand letting folks know what they are getting into prior to diassembly.
