Pistons by fireman725

I am rebuilding the engine of my 2001 3.9 liter dodge dakota. I have to replace 3 pistons and connecting rods, this will make me have 3 old pistons and 3 new pistons. Will this matter in the performance of the engine when we I start running it again? I'd rather not spend the money to buy all 6 new ones but would it be worth spending the extra money replacing all of them or no?

Melted EGR Valve and power loss by nanell
May 29, 2008 (8:25 pm)

To start out I have a 1994 dodge dakota V8 5.2 liter automatic. ABout a month ago I started to loose power and it would die on me. So I replace the EGR Valve as suggested by people on forum.
 
But today while driving, the truck sounded as if it was not in gear and then would not accelerate well no matter how much I pushed down on the gas. Then it sounded as if there was air coming out of a hose. When I pulled over and took a look it smelled like melting plastic. The plastic part of the EGR valve was melted. So I replaced the EGR valve again.
 
And after a few blocks it sounded as if the valve blew again. ANd sure enough the valve looks as if the very center of the plastic piece is melted or blew straight down the center of it.
 
Any help or suggestion of what I can do would be really great.

This might be a bit late but have you checked the EGR valve? It is not the cheapest part (about $100) but is very easy to replace. Let us know what you figure out.

SO after dealing with 2 dodge dealers and the local shop found out that the catalatic converter was the problem. It had broken in ternal part that where causing the exaust to be to hot and that was what melted the Egr valve.
 
SO got that replaced and then put in the 3rd EGR valve and it runs like it should again. Wow forgot what a beast it is. Thank you to our local Shucks who replaced not 1 but 2 melted EGR valves under warranty for us. There customer service is awesome. ANd I have to drive by 4 other parts stores to get to them but it is worth it.

The 2 engines are VERY different.
 
Here is a write-up on the 4.7L semi-hemi. (with photos)
 
Perhaps this will help you identify your engine.
 
HINT: The 4.7L does not have any sparkplug wires while the 5.2 does.

I'm pretty sure that after 2000 the 318 (5.2) was no longer available.

You should have no problems swapping in '98 to replace a '95, they're both Magnum versions. A '92 might be better. They used a larger exhaust manifold and were rated slightly higher in horsepower.

Dusty
