I recently redid the head gaskets in my engine...
I'm getting major air pressurizing in my return fuel line near the fuel filter. Makes for a hard start if I don't start it on the first try. If I do start it on the first try, it runs with too much blue-white smoke leading me to believe its got air coming through the lines. When I turn it off after running it for a minute or two I can hear a hiss when I take off the return line from the filter elbow-- mostly air, very little diesel. Can a leak at a injector cap or return line really cause this much air intrusion? (I replaced 2/3 of the injector o-rings that seemed like they would not reseal-- i know that was poor judgment. I also have new return hoses) My neighbor has a slow leak from an injector cap but he can still start his truck reasonably well. Is there some other place that could cause such an obvious air leak? I replaced the sleeves and o-ring in the fuel filter to injection pump metal line connection because that seemed to be eaten up pretty bad. I had heard theres a check valve on the injection pump return... can this leak badly enough to cause major air leaks?
