I have seen information that suggests the front seal onn the injector pump will wear and cause leaking fuel into the crank case making it lose pressure until the engine warms up and the seal swells. check the oil level to see if it is over full..
Post back with more information or if you have more questions.
Ok, a couple of possibilities are the glow plugs or glow plug relay. Glow plugs heat to start and also do what's called post heat to raise the cylinder temp until the block is warm. To see if they are not functioning, clip a test light onto one and switch the glow plug on to test the relay. This is a common wear item.it could also be a stuck EGR valve - If stuck open it run a very lean mix when cold. It's two bolts on the inlet manifold, pulls out and looks covered in soot - it should push in and spring out. Can be cleaned in carb cleaner, gasoline or alcohol and blown off with compressed air. Post back with more information after you look into the mentioned items.
egr valve is not stuck,its all clean and working fine
do you have any other suggestions?What about the thermal advance solenoid?I'm thinking its an electrical problem now ,not mechanical.
