Lq9 pistons pressed on lq4 rods?
 

I already pressed brand new lq9 pistons onto lq4 rods that had 60,000 miles on them. What do you guys think?

Unless the rods are bent or fatigued from abuse... I say you're good to go. I got 83,000m on my LQ4 when disassembled it for kicks while it was out. Rods looked great, and unless you're running heavy amounts of power adders, (Forced Induction, Nitrous) i wouldnt worry one bit.

Thanks for your input!

I have another question. I have this engine diassambled down to the block by a buddy of mine and now all the bolts are all over the place. i don't know which bolt goes where? Do you know of any literature that would help me.

Take pics of the bolts and number them with photoshop and Ill tell you what each one is. Im way too familiar with them:jest:

I dont think you'll have any problems but I am curious as to why you went with LQ4 rods instead of LQ9. The LQ9 rods are a little stronger, which I would assume a little heavier. Was weight of the rotating assembly a concern?

Well i figured the rods were fine and i really did not want to spend too much cash on this rebuild. I wanted to make it quick and easy but unfortunetly i have been to busy and i have let the engine get a little rusty. Now i have to take time and carefully clean the block. And i have to round up all these loose bolts.

hey what wrist pin did you use and what was the outcome of the engine?
