i just put another engine in my 2000 cav ld9 and this time i had to reset the timing, so i had to crank it for 15 to 20 min to get it to start thinking the lifters were stuck but now when i did get it to start it runs like crap, almost no power at all and smoke is coming out of every oil hole on the engine. i think it might just be a couple of bent valves does anyone have any other ideas?
