So, is the manifold bolted in a simply as it appears? Or are there secret hidden nuts/bolts placed with the intent of bashing my knuckles? | | | | | Joined: Jul 2006 Posts: 707 Shop Shark | | Shop Shark Joined: Jul 2006 Posts: 707 | They are all placed as they are with the intention of making you bleed. When you bleed on your stovebolt, a holy union ensues, so be happy. Soak 'em all down with penetrating oil before you crack 'em, and don't forget to check the plane of the manifold before reinstallation.

Bleed from the knuckles. 2. Bleed from your eyes (cause your so po'd at it). C. Bleed from your wallet to pay for new parts. Thats why we love our Bolts! | | | | | Joined: Sep 2001 Posts: 581 Shop Shark | | Shop Shark Joined: Sep 2001 Posts: 581 | Ditto on the outer dowels to studs replacement. Think my fresh rebuild may have an exhaust leak at the front. Wishing I could tighten down that outside edge! :mad: If it makes you feel better about the bleeding, I managed to shower myself in Coolant lastnight in the process of removing the thermostat. I may not have been "one with the truck", but I sure smelled like it!  -Michael | | | | | Joined: Feb 2000 Posts: 5,191 'Bolter | | 'Bolter Joined: Feb 2000 Posts: 5,191 | The bolts holding the whole mess to the head will come off pretty easy, its the three holding the intake to the exhaust that could give you trouble. If you heat the area around the bolt, but not the bolt itself, they should come out. Take it off as a unit, separate them and check the condition of the surfaces. They wear pretty bad on the exhaust side right under the intake. If you plan to have them machined, go ahead and bolt them together solid. If going back on the engine, leave the three bolts loose till you get the whole unit bolted to the head. Once on the head, snug all the bolts down, starting with the three hold together bolts, then working from the center out, tighten the others. Joe | | |
