Anyone know where the best place to buy a complete rebuild kit for a 89' Cherokee Laredo 4.0 inline 6 would be? Hopefully with pistons and valves too

 

Why does it need pistons and valves?

 

It needs a complete rebuild. I found kits with everything but pistons and valves

 

Why must everything come from the same vendor? Just buy whatever you need.

 

I've rebuilt a few of these and there was never anything wrong with the pistons and valves.......

 

if your going that far. Why don't you check out Clegg and build up a small stroker motor ?

 

here you go.

I'd let a head shop determine whether new valves were needed. And I would guess that you don't need 'em. A place in NC will sell you a refurbished head for $275.00. ebay

 

top end failures are far more common than bottom end. valves are cheap enough that it wouldn't be a huge cost difference to replace them. they do wear out, you know. and at that point why let everything ride on a 200k+ mile piston that has the potential to come apart for no reason. idk about you but my eyes can only see so much and my hands can only do so many tests verifying proper function and condition of metal parts that have A LOT of use on them already. if I was rebuilding an engine expecting another 2-300k miles out of it I would replace everything.

 

(off topic) i think i follow you on IG. but if your not sure on what you need i would have a shop do it, im getting my entire engine rebuilt for 1,500 this spring

 

Agreed for the cost

 

Yea, and I don't wanna do that.. Id rather do it myself since I go to school for automotive anyway

 

Ah in that case go for it!
