Thanks Reed and wish me luck.

| Post subject: | Intake Manifold removal |
Is it possible to remove only the intake manifold without removing the exhaust manifold? The vacuum valve on the rear of the intake manifold was broke and leaking. When I tried to remove the valve, it snapped off like a twig. It had the frailty of a saltine cracker. Anyways, now I need to remove the intake manifold, tap out the hole and rethread it for a new valve. Any tips on an easier removal and installation would be greatly appreciated. btw - I did read the article on manifold removal but it focuses on mainly exhaust manifold removal. |

This will depend largely on wether or not you have a stud or a bolt on the inboard nut fastening thre intake and exhaust together. Both were used from the factory. If you have a stud, forget it, but if you have a bolt you *may* be able to sneak just the intake off. Of course, the only effort you will save is removing the two outboard most nuts on the exhaust manifold. |

The practical answer is "No". You will have to replace the manifold-to-head gasket as soon as you pull either manifold, so you must pull both. |

I always combine exhaust and intake business at the same shop (my headers shop, they're cool enough so everytime I want to try something diffrent on the intake I go to them so they reseal the whole thing.) I end up loosing no time guessiing at exhaust or intake vacuum leaks.. straight to the business of tuning up the diffrent carb/s. 99% they don't charge me but I solved the emarrasement to myself tipping them big time...  so they're happy and I can have a place to "play" with in/ex combo w/o going thru pain in the butt sealing issues. I usually leave the car overnight to zero cool down and then take it there in the morning on a truck deck w/o even touching the starter. Zero cool is zero cool...

Mission Successful! In ten years I have never had the manifolds off. No broke studs and everything sealed back up good. I wanted to replace all the studs but couldn't find any on a Sunday. Oh well, building a new engine this spring. |
