Head removal, rings & cylinder
I'm trying to sell a 2005 Rhino 660. I've only owned it a short time and I go thru a lot of oil (like 1 Quart every 300 miles). It will occasionally puff some blue when you follow it, but hard to see, and only sometimes (like hammering gas pedal). The dipstick movement doesn't lie, and I'm not leaking it at all, so i assume the consumption is either rings or valve seals (maybe valve guides, but I'm really hoping NOT on the guides). I only have 2000 miles/3500Km on the rhino/engine.
Unlike the guy I bought from, I find it hard to knowingly screw someone and not identify the issues. I'm mechanically inclined and have worked on other small engines, just re & re'ed car tranny on Nissan, etc.. I can do this myself and i can't afford to pay a shop (except for machine work).
I have a Rhino repair manual. There are 30 pages of info on removing cylinder head cover, cylinder head, then finally getting to the cxylinder & piston. Basically, i want to get the jug either honed or re-bored (whatever machine shop tells me), replace rings, and valve seals. I think that will do it all. So how much do i have to remove/do to get to this point?
I assume the overhead cam needs to come out, and I need to keep timing chain in place so it doesn't move. But all the pages on rocker arms, valve removal, etc... I don't want to do all that. Can I remove in sections, with that stuff intact?
Do I need to drain coolant, or can I just disconnect coolant hoses? Can I take the head to the machine shop with valve train assembly together, and have them tell me what I actually need?
I want to be thorough, but I also don't want to do a bunch of stuff I don't have to do. Right now I have the engine at TDC on compression, and I've walked away for the night. I need to get this done ASAP.
I was going to get whatever shop says i need and I was hoping the piston would be fine and no rebore necessary. i was going to buy a set of Tusk gaskets from Rockymountain ATV for $26. I've read mixed reviews on the quality of their head gaskets. Anyone had any expereince with their gaskets?
How hard are valve seals to do, while I've got htis apart?
