It pains me to have to admit this - I though I took more care to keep everything organized..
While doing exhaust work on my truck I had to take off the heads (which means intake, valley pan, throttle linkage, other bracket/s also) to get broken exhaust studs extracted. When I went to reassemble the engine later I ran into a problem finding all the bolts, understanding where some of the brackets go, and identifying what bolts go where (of the ones I did have). My engine is the type with a valley pan and the intake design that goes with that and the Chilton's manual diagrams seem to be for the other style of intake. I'm going to look again in other places in that manual; but, so far, I haven't found anything in there that shows the location of throttle linkage brackets and other brackets that came off during the disassembly. Also I need to be sure I use (or buy replacements of) the proper bolts for the place that they go - proper dimensions / length / design and match the right ones to where they really go. So far I've managed to find / identify the following bolts..
- Valve cover bolts (12)
- Valley pan bolts?
- Intake manifold bolts?
The heads are back on already so that's out of the way. All 6 bolts that I think go to the front / back of the valley pan are the same length BUT there is a bracket that uses 2 of the holes in the front of the valley pan that is maybe 1/8 inch thick - I'm not sure of those 2 bolts should be longer than the others (see pic)? I don't remember them being longer but it kinda makes sense. The intake manifold requires 8 bolts (4 on each side) but I can only find 7 (that I THINK are for that). Those ones have a piloted tip (no threads on the very tip of the bolt until about 1/4 inch up). The thing is there's a bracket for throttle linkage that I THINK goes on the rear most manifold bolt hole (driver side) but I'm not sure. It is also maybe 1/8 inch thick - same thing - I'm not sure if that one bolt needs to be longer? Again, I think I remember them all being the same size; but, IF that's where the bracket goes, it kinda makes sense that that bolt MIGHT be longer than the others? I'm also unsure how the manifold is to be oriented. There is a place next to the carb studs on the intake manifold with 2 holes (so something bolts there??) - LORD HAVE MERCY!
I'm either missing bolts, missing a proper understanding (for sure), or mis-identifying where bolts go. Probably a combination of all of that. I've got to get the ol' girl back together though.
I'm in a real pickle guys. I'd really appreciate any help you can give me. If any of those holes are blind holes I don't want to damage my block or heads by using the wrong length bolt (if I have to buy replacement) and I don't want to use too short of any bolt and have it not hold securely.
Picture above taken before removal. That bracket and valley pan are currently off the vehicle. Picture was taken from the driver side of the truck (the distributor sits at the front of the engine and is pointing toward the passenger side).
I think the numbers stamped on the manifold go toward the front of the engine. That would make the two holes next to the carb studs be on the passenger side (not the throttle linkage side) in that case I would be unsure what goes there. Also bracket sticking up forward of the stamped numbers I am not sure what that is for.
