Intake R&R advice

AllGMV8 · February 28, 2006

My 98 Suburban SLT 1500 has the dreaded intake manifold leak. From my searching here I see it's not an uncommon problem and people have replaced their own, yet nobody here has posted a step-by-step how-to describing the process of fixing it. Since I enjoy documenting my projects (for example this one), I will probably do a writeup and offer it to the forum. I live in Michigan so I'm not going to attempt this until it gets a bit warmer outside because my garage is not yet insulated, maybe another month or two from now.

From everything I read (yeah, I searched) it seems the hardest part is keeping track of everything you remove from the intake before pulling it. Are there any special tools needed for the job? So far I figure you need a torque wrench, sockets, gasket scraper, non-silicone RTV, tape to label parts, camera for documentation and rags. Are there any special fittings that require special tools? Are there any other parts that commonly break that would be good to have on hand? Is this really as straightforward as I am thinking it is? I'm by no means worthy of calling myself a mechanic, but I can take most things off an engine and replace them without a problem.

Thanks,

Adam

One of the easier jobs to do if your mechanically inclined. The only hard part would be to reinstall and time the distributor if you have one and even that isnt too difficult if you know what you are doing.

A fuel line disconnect tool will be needed. Everything else can be handled with what you have identified so far. I have a write up a friend gave to me which recommends blue loctite for the intake bolts when putting back on. Really wasn't that hard of a project. Like you said, just remember where everything was when you disconnect it.

It's a 350 Vortec. And if someone has already done the documenting, I'd be more than happy to just follow the instructions. I have the Haynes manual and it describes the process but with only a couple pictures so I'd be happier if I had another source.

Thanks!
