Going OUT of my mind by ronindelaware

Hello,
     I have a '98 Dodge Dakota, V-6 , 3.9 4x4. Its been a good truck over the years and I have taken care of it the best way I can. Its got me around 188,000 miles, I cannot complain much. Low cylinder compression in cylinders 4 and 6 . OKAY needs a new head gasket.
Tore it all apart and swapped out the gaskets with the top end overhaul kit.
New cylinder heads- cause they were cracked.
  OK.. RE-INSTALLING the heads went fine - torqued down to spec.
Now I am installing the INTAKE MANIFOLD onto the heads and I keep snapping bolts--#1 and #2 in the sequential order. I replaced the bolts and bought a new torque wrench- Craftsman dial- in torque release---How could one go wrong? Snapped another with Dodge dealer bought bolts and new torque wrench---
  Haynes book says to tighten to 12lbs and rock around up to 144 lbs---Dodge dealer said to start at 24lbs to 48 to 82 lbs---I have tried Haynes first and broken bolts ---redid everything and tried Dealer way---still same results.
 What is the proper torque spec and foot lbs; so I dont have to keep replacing bolts ?
        Please , any help would be Wonderful. Losing my sanity in Oklahoma . Thank-you

I just bought a 99 Dakota with a 3.9lt and 63,000 miles in it. The truck was not used for about a year at the time I got it. I have change the oil and filter as soon as I've got home. Couple days ago the pressure gauge hits 0 for a couple of seconds and then got back to normal. It does that twice on the same trip. Tonight it goes down to 0, never came back to normal, I was close to my house so I just got there. I turn it off, wait for a couple of minutes and start it back. The engine start to make some noice (I guess it was the lifters). Any advice from someone. Should I replace the pump and start praying?

Hmmm. The older 3.9 motors and 318s required a 35 lb. torque for intake manifold. Are you sure about the 144 foot pounds?

Oil pressure falling that rapidly then rising again usually indicates a clogged oil pump inlet screen. I suppose you could have a bypass valve that sticks intermittently, but I've always seen them stick in one position and stay there.
 
Looks like your going to be pulling the pan anyways.

Dusty
 
P.S. I once found an oil pump screen blocked by a heavy paper return parts tag on a '70 Ford. That engine had 16,000 miles on it before it seize from lack of lubrication.

same thing happened to my 02 but what i found out is that the studs that are in the block unscrewed by finger and i had 4 of them broke, i took one of the broken studs to my local part store and they hooked me up with what i needed.
