Can you drive with an intake leak?
As far as driving the car, as long as you don’t have a fluid leak or the car is not stalling or running rough, it should be fine to drive for a few months. If your engine stops turning then you will stall, although there could be other reasons for a stalling engine, faulty intake gaskets will be one of the problems.
Will an intake leak cause high idle?
A vacuum leak in the intake manifold allows excessive air to enter the engine that the computer cannot compensate for. This can cause the engine to stall, it can cause a very high idle rpm, or it can cause the idle to constantly rise and fall on its own.
Can intake manifold leak cause low compression?
A bad intake manifold gasket will not cause low compression. Bad head gaskets can cause low compression. If your intake manifold gasket is not sealing, and you have low compression, it is possible that your engine is bad.
Can an intake leak cause a misfire?
Yet damaged intake manifold gasket tend to be one of the most frequently experienced causes of engine misfires. Such a leak alters the engine’s air–fuel ratio — one of the most important factors in promoting complete combustion. A bad enough leak may allow enough air to escape that combustion cannot occur at all.

What kind of intake manifold does a Ford 351C have?
The Performer LB 351C-4V manifold is designed for 351C engines with the factory 4-barrel heads. What you get from this dual-plane manifold is the Holley 4150/4160 baseplate flange pattern and long, high-ceiling intake runners that improve low- to mid-range torque. Valley width is 6-31/32 inches for the 1970–1974 351C only.
What causes a head to crack on a Ford 351 engine?
Overheating is the most common cause of cracked heads in the 351C engine. While thermostat failure is a common cause of the overheating, bad radiators and radiator caps, failed water pumps, and coolant leaks are also common overheating causes. 351 Cleveland cylinder head cracks most commonly occur across the exhaust seat and in the lifter valley.
What are the problems with a 351 Cleveland Engine?
Oil starvation is a common problem on 351 Clevelands which can cause the valve guides to receive inadequate amounts of oil and therefore wear down more quickly than they normally would. If the guides are excessively worn the valves can get off-track and close against the seat at a slight angle, eventually leading to cracked valves.
What is the valley width of a Ford 351 engine?
Valley width is 6-31/32 inches for the 1970–1974 351C only. There’s also the Performer 400 non-EGR and EGR manifolds for the 351M and 400 engines with long runners for good low- to mid-range torque, which are compatible with 2-barrel heads. Valley width is 8 17/32 inches for the tall-deck 351M and 400.
