What should I do if my manifold is stuck?
If that is the case you should be able to pull the manifold off and then address the stuck bolt separately. A good soak with PB Blaster always helps and the previously mentioned trick where you weld a nut on to the top of the broken bolt works surprisingly well.
Where is the intake manifold on a Ford 302?
While trying to remove the intake manifold from an old Ford 302 one of the bolt snapped off. As you can see below it is just about flush with the manifold (just below.
Do you have to use an extractor on a manifold?
The bolt extractors should really be a last resort. The extractors are much harder than the original bolt, and if that extractor breaks off inside the bolt, you just made your job a lot more difficult. Drilling through normal manifold bolts is cake compared to drilling out an extractor.
What are torque requirements for intake manifold bolts?
The torque requirements of the head bolts and the lower intake manifold bolts are specified in the manual, and should be followed, since the head is aluminum and thus a little vulnerable to damage.
Where is the lower intake manifold on a Chevy?
The lower intake manifold is the tricky part. You have to jack up the motor and remove the passenger-side motor mount in order to remove one of the bolts from the intake manifold. The power steering reservoir is bolted to the block right over one of the bolts to the lower intake manifold.
What to do if you have a leaking intake manifold?
The more reference points you have the better. Zip-lock bags are a must. Put all the nuts, bolts, small gaskets, and small parts you remove into a bag; then label the bag with the name of the particular part. Seal the bag and put it in a safe, clean area where it will not get lost or moved.
Why is my intake manifold leaking coolant into the oil?
The lower intake manifold gasket fails and leaks coolant into the engine oil. I had the dealership replace the manifold gasket the first time at about 40,000 miles before it got to the point of leaking coolant into the oil. This cost me $1200, mostly for labor. Then, just 15,000 miles later, the gasket failed again.
