Did the motor get over heated? Good luck with that though.

well it has overheated twice but it was about 3 months ago was the last one and 5 months ago was the first one. replaced the water pump twice and radiator...keep gettin that tanish oil/coolant on the bottom of my spark plugs, just got the oil changed today but its really hard to get over 60 now ever since i got it timed. could it have been timed incorrectly?

you need a head gasket and possible new head,your mechanic should have known this or learned this when he ran it after working on it.have head milled and pressure checked and if its not to warped or cracked reinstall or replace and it will run sweet.good luck,,,dont let anyone talk you into just putting gasket in without haveing it checked for warp/cracks,,you will be wasting your time and money

if the valves are burned its from a timing or lean fuel mixture,if you overheat from a water pump or leak you get a wapped or craced head
