    2004 RXP dropped valve; Cracked block repairable? Need Advice

    Hello everyone,

    Well long story short my buddies 04 RXP dropped a valve. I pulled the head off for him and found the head is junk, piston banged up, and the sleeve/ block cracked. Does he need a new case or can he have the local weld shop Tig weld and re-sleeve?

    Anything else to replace besides updating the flywheel bolts?

    Best place to purchase gaskets and required bolts; connecting rod, rocker arm, and head?

    Thanks in advance!

    It would be best to replace the block with a Clean Block with std bore. I have a rebuilt head READY to Install for $500 plus shipping. You will need a 03,04,05 era block with has the Oil regulator fitting in block & head gasket area.. If you go to a later block 06-2012 you will need a different rocker shaft to regulate the oil flow to the upper rockers & lifters. This repair will be expensive with the block, head and Timing chain lost, also will require all gaskets & all new brgs & new rod bolts .. Plus a new piston assembly with rings. I have redone a couple in this cond. it is Expensive to bring it back to life..

    Thanks for the response. That's what I pretty much figured was going to be the case. I believe he already has a hit on the parts but I will inform him in regards to your head for sale. I was wondering if it was even worth fixing. Better to part out or sink the money into? Cost comparison
