Intake R&R advice

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.

what engine is it and i will get the step by step for you

 

 

 

 

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! :thumbs:

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
