After searching high and low for a 2.4 TDCI engine after ours died lasyt year with over 300K Km's we eventualy bit the bullet and bought a brand new one which was sent out to France with 4 new injectors etc. Timed new engine up with the injection pump off the old engine using varios corresponding tutorials off the internet, programmed new injectors useing nanocom evo . Swapped all the auxillaries over useing new gaskets, water pump etc , filled with oil, coolant, turned engine over first on the starter with the crank sensor disconected to prime with oil and she fired up first time . Let her get up to temperature on tick over and all was good, no leaks, everthing spot on ! But : There is a tapping ! Can only be heard above tick over and when the engine is warm ? Starts and runs absolutely spot on, no smoke, no engine fault codes but as soon as she gets up to temperature there is a rev related tapping ? Engine supplier thinks that the timing is out and its the pistons hitting open valves ? Knowing that the timing was the most important point of this operation I took a lot of time to maticuously set it by the book ! Engine supplier since suplied procedure and corresponds with exactly how it was done . ( 2 x cam cogs locked with 6mm drills, flywheel locked with special tool through crank shaft sensor holder, 3 black links on chain lined up with arrows on cam cogs and hole in injection pump cog etc ) We have listened with a stepthoscope over every inch of the engine, scratched heads, checked , re-checked, injectors bolts etc to no avail . Absolutely unbelievable ! Just can't believe it ! if anybody could shed any light it would be much appreciated. Thanks in advance |
