Hey everyone been lurkin around for awhile decided to register especially cuz my truck started acting up recently, let me give you a little info on my pickup, its a 98.5 OBS ECSB, rebuilt auto transmission,5.7 vortec, cold air intake, 6" BDS lift, on 35s, and not much else, its always ran fine, fired right up and ran with a lot of power, now lately it seems to be losing a little bit of power not a whole lot though just noticeable on the highway and sometimes it almost sounds as if its missing when it first starts at lower RPMS this clears up though, and its really hard to start (cycling the key doesn't seem to help) usually takes 3-5 times of crankin to start. and its started smoking some white smoke with a little blue in it and it smells really rich of fuel, im concerned about the smoke and hard starting and overheating Also the first time it overheated I checked the coolant immediately and it was 1.5 gallons low.. was full two weeks prior and I never noticed spots or smoking before. SO I topped it off and it continued to get hot, I then noticed that my overflow was filling up? so I replaced the radiator cap and it seemed to fix the problem, no more overflow full and no more overheating, then the other morning it overheated again and the coolant overflow was full again... thermostat opened and the overflow drained back to the radiator again, hasn't overheated since but the smoking seems to be getting worse, oil has no coolant in it, coolant has no oil in it, I can't see any obvious leaks. SO far I've replaced the radiator cap, fuel filter, plugs, wires, cap, and rotor just because it was due for a tune up. Trucks got 195,800 miles on it. Im weary of driving it anymore because I don't want to cause anymore damage. Im hoping I can avoid having to rebuild the engine but I'm not afraid to if I have too, just wondering ya'lls opinions?
