New to the forum need help
 

Hi everyone. I have an Isuzu Trooper it's an 01 and it needs a new engine. I have swapped the engine tranny and T case in my jeep before, but I have never swapped just an engine and unbolted the engine from the tranny. Is there a certain way to seperate the engine from the tranny without damaging things? I'm just looking for any advice that you guys can give me to make the process go smoothly. I can't seem to find any writups on it. Or picks would be great too.
Also, it is the 3.5L and I have found one for $2000 shipped, cause they're kinda hard to come by. Are there any other vehicle models that use this same engine that would be a direct swap?

Thanks in advance. Klinton

This is strickly by the book. There are easier ways to do it once you get hands-on into it.

NEUWBEA;

What was the source for your answer NEUWBEA? I just bought an 86 Trooper with the engine all torn apart and sitting in the rear; A REAL BASKET CASE.
I have the Chilton manual to help me; but it doesn't lay it out like the directions you just gave. Where could I find an answer for my 86 Trooper like the one you gave to Klint? Mine is the worst basket case I have ever seen; everything is all mixed up and tossed into boxes. Today i am going to start by cleaning all the gunk off everything; and then trying to put the parts into some kind of order. Directions like you gave Klint would be a fantastic help for me.

Hi Tim;
Thanks for your answer; but when I click on the word "EngineEngine nothing happens. If you notice there is a red X beside the word Engine. So I am assuming something didnt didnt get sent correctly; but I really dont know. I am sadly lacking in computer skills; so please let me know what I am supposed to do.
Thanks
