Enjoy....

 

Again, I'd spend the money on a good scanner - such as the generic ELM327 Bluetooth adapter I mentioned, which can be had for as low as $3.27 on Ebay (note: not saying those are good ones, but that they're darn cheap nowadays) and Torque for an Android phone or tablet with Bluetooth capability can be had for free (Torque Free is the name).

For that kind of money, NOT having a OBDII scanner that can read the data streams is pretty darn not-smart, IMO.

It just blew up lost all power and then shut itself off

 

What do you mean "blew up?"

 

Lost all power wouldn't go over 30 MPH I was right at my house so I coasted into the driveway horrible noise from the motor then it shut itself off.

 

I got it to start back but it struggled really really bad and took a little bit to start. Now that it is at the house idk wat to do replace the motor or fix wat ever the hell is wrong with the one that is in it.

 

I'd say "Yes".

Ideally, find a good core in the boneyard, and rebuild it then drop it in. Edit: If you have the 3.9, may want to look for a 5.2/5.9 from a 1998, and pull the ECU and the extra two injector wires also. Be a good time to beef it on up! EndEdit

Secondly, pull yours, rebuild it, and drop it back in.

Both presume you have another daily driver you can use during the rebuild time.

While rebuilding, check out the various Mopar forums (not just the Dakota ones!), grab a couple of the better Mopar LA/Magnum rebuilding books, and pour over them.

(The Magnum block you have is a derivative of the LA block, and as long as you brace for the differences, a lot of the steps are the same between them - and as long as you stick with the Magnum variants for when they're different, a lot of the parts are comparable / interchangeable.)

Sounds like you did lose oil pressure, not a gauge failure, in that motor. Not being there I have NO idea what you did or didn't do to cause it with the intake manifold job. And it's possible that it's coincidental. "Commonality does not always imply causality". Sometimes B breaks when you work on A, but A would have broken anyway!

Well from wat I have seen with wat little I have tore into the Motor isnt actually that bad. Spun a Rod Bearing. Gonna change the Rod and Main Bearings, Main Bearing Housing, get the crank refaced and balanced and should be good. Other than changing the Oil Pump and the Oil Pickup tube.

 

While the motor's apart, do the timing chain/gear set. And I'd suggest considering adding the tensioner to replace the cam retainer.

Well I got the motor out and everything and have finally seen the worst Pick Up in my life like for real WTF.
