    What to replace whilst the engine is out

    All, 2006 RXP with 40 hrs on engine.

    I am doing on engine upgrade to handle more power and so am replacing the pistons and rods with CP / Carrillo etc as well as valves, retainers etc.

    I am just putting together my order for genuine items that I will need. So far on the list I have:

    Big end bearings, main bearings, balance shaft bearings, thrust bearings, head gasket, PTO cover gasket, oil pump rotors & plates, timing chain and guides plus 08 oiler mod parts.

    Anything I am missing?? Full list and part numbers below.

    Would you all replace these parts? Someone said that I could save money and not bother with the bearings, measure the wear on the pumps and go again with the chain as it's low hours.

    My gut feeling is whilst it's out, replace everything so I know it's good rather than something going bang in 6 months and costing more plus the hassle.

    Don't get me wrong, money is tight and I want to save where I can if you get my drift.

    Thanks

    I would change all of the above. Check motor mounts and carbon seal.

    Yeah I have new racing mounts to go in. Carbon seal is on the list as well, just looking at internal engine parts on the list above.

    I would change your oil pressure valve and spring,flywheel bolts and the O-rings that are on the main bolt plugs...you would hate to put it all back together only to have to pull it to replace one of them O rings....

    Thanks Snoman for the oil pressure valve and spring. Flywheel bolts, head bolts and rocker bolts are going to be ARP. Good call on the O Rings, thanks again.

    Orings should come in the gasket set, which I assume you are going to purchase.

    Well who ever told you not to replace the bearings do not take any more of his advice in the future. Best to get Oem gasket kit it will come with all your orings pto gasket Oem head gasket, valve cover gasket, valve seals blah. As far as oil pumps no in your manual there's a section take your feeler gauge and measure gear gap and spacing I doubt there's a issue. Chain guides, oil pump covers scratch as well. I'm assuming the rotors on the list are the oil pumps leave them alone measure and inspect and walk away. I will give you a little advice on the 2006 what I did on my build last year is replaced all the bolts( they are not stainless and rust like a mofo) with stainless steel marine grade for like 100 bucks. I have all the sizes some where if interested. I have my complete build list on my current list if you care to know I will be happy to help out good luck

    Shrabber, the bolt change is a great suggestion. The parts catalog have the bolt sizes for easy reference.

    Yes and thanks, if you have a list off all you done that would be great. Thank you.

    So you can get a whole gasket / seal set? I could not find an OEM part number for it.

    As for the oil pressure valve and spring, it looks like there is a choice of two springs. 420939210 or 420939400 that both are item 12 and state that they replace 420939410. Any ideas??

    Good question...I dont know which one is which...Also as long as you have the PTO cover off i would replace the water pump seal......
