Engine question

[Whamm]

The 2.5l that i have now is starting to go south. :fs1: I pulled a lifter out and had a hole in the bottom of it where it met the lobe of the camshaft. I have found another 2.5 from a 86' manche for a pretty good price.

Couple of questions

1. Is the 86' motor a carburated motor?

2. If so, will it still work with my 90 which is TBI? I would still like to use the TBI if at all possible.

The 86 2.5l has throttle body fuel injection. Only the 2.8l Chevy V6 was carburated.

Thanks for info.

 

I'm still not sure which is better to rebuild or buy some one elses possible problem child. :dunno: .

i depends on what u are paying for the motor i think it was $400 to rebild the short block $100 to do the head

[Whamm]

The "new" motor is about $350 with 103,xxx miles on it. I was just afraid that i would be inheriting someone elses problem child.

 

My current motor has 275,xxx on it and not sure if has been rebuilt at all. But i do know that the PO had replaced the timing chain with one from a 4.0 (mines a 2.5). :nuts:

 

 

I figured it coust around $400 to rebuild my motor. Thanks for comfriming this.
