How are the intake manifolds on an Oldsmobile used?
How are the intake manifolds on an Oldsmobile used?
Further, a special vaccuum linkage was used to allow the end carbs to go from closed to WOT at 68° throttle opening on central carb. Central carb provides all fuel for idle and off-idle! Lack of this vacc system will require a jury-rigged mechanical linkage, if you can scrape up the carbs at Ye Olde Junque Yardes. There are 371’s lying fallow.
How is the IAC connected to the throttle body?
The IAC may be part of the throttle body or connected to the intake via a smaller intake hose, off the main intake hose. After intake air passes through the throttle body, it passes into the intake manifold, a series of tubes that delivers air to the intake valves at each cylinder.
When did the holes in intake manifolds get bigger?
Secondly, the throttle plates of the appropriate 2-Jet carbs were small, about the size of quarters, the later 2 barrel throttle plates (and appropriate holes in intake) were visibly larger from about 1965 and after.
Where do you find the firing order on an Olds intake manifold?
Not to be confused with the 8-digit firing order, which is always 18436572, and usually marked with the words “FIRING ORDER”. Each runner has a raised number corresponding to it’s cylinder number cast into the top surface of the runner. There’s a casting date codeon the underside of the manifold, on the heat crossover.

What are the symptoms of intake manifold problems?
1. Engine misfires and decrease in power, acceleration, and fuel economy. One of the most common symptoms of an issue with intake manifold gaskets is engine performance issues.
