[QUOTE="superpsd, post: 1439676, member: 15821"] An injector that works perfect cold but fails when the oil is warm can the a worn upper poppet valve seat and high pressure oil is being lost especially when the viscosity changes due to warm oil. If they are remanyfactured they may have not been bench tested. Even with bench testing depending on procedures it seems sometimes a set that tests perfect will still have an issue. It is also possible the oil sides have been shimed to compensate for worn poppet valves. Mandkole is on the money. [/QUOTE]
