    2008 ultra 250x 60 hours - MILKSHAKE

    hey guys - first post here - new member

    i have a 08 ultra 250x - had a hard start after sitting for 3 weeks (sounded like no compression/fast crank)- after cranking for a while and starting noticed top end rpm loss and stalled a few times - upon inspection noticed it to be 2 quarts low on oil - added oil - all milky - pulled head - its at machine shop -pressure tested - its not cracked and they are telling me its warped 4 thousanths and exhaust valve are not holding vacuum - any ideas ???
    is it possible this happened from flushing a hot ski with cold water -
    is the water coming in from the warped head or could the water be coming into the oil from somewhere else like the oil cooler???
    not sure where to go from here


    **UPDATE - machine shop just told me exhaust valves are all hammered and need replacement
    does anyone know if they valve guides can be purchased??

    does anyone have the valve lash specs>>

    yes you can purchase stems and seals dont think they would be hammered at 60hrs though, how much trust do you have in these guys, i have had two cracked heads best you do a search here and find the you tube clips as the second head cracked on the camshaft side and never showed up during a standard pressure test. good luck

    cant find the youtube links but ive seen all the pics - i dont know what to do at this point - im going to tell the machine shop not to start milling and replacing the exhaust valves - dont want to waste 350 labor + a few hundred in parts only to have the same problem - i guess i need to buy a new head -

    no one is saying buy a new head just make sure it isnt cracked i would be more concerned with them saying the valves are hammered at 60hrs, at the very least they should only need a light lapping
