hey robert,thanks for the diagram of the peugot 406 timing gears,have been

doing the timing correctly before,but the problem still persist,at half engine rotation the valves are still totching the piston,what am i doing wrong,remember the head was totally removed,and replaced,valves refaced,some of the hydrolic tappits were sticking,i freed them up,what what am i missing


Still sounds like the timing is still off somewhat if your sure the valves are still have to be sure the no1 piston/cylinder is at TDC "top dead centre" or the crank is..if you remove the no1 spark plug and insert/drop in place for example like a welding rod then turn the engine over by hand uptill you see the rod rise to its highest point that should be at tdc then check the timing hole on the crank to insert the pin,also ensure the cams aren't out to - then try re-fitting the belt once both top pulleys are lined up and see if that helps..other things you may want to recheck is for the possibility of the wrong headgasket "thickness" maybe,did you make sure you put the right cams in back in the correct place ie: inlet cam hasn't been swapped with exhaust cam..

ok robert,all that you are saying makes sense,the cams are in the correct place,the head gasket is the original gasket,the one thing that i am not sure about is if the head gasket was put in correctly,it was done by one of my wokers un-supervised,but your advise was helpfull,thanks,

i am the propiator of an auto and diesel mechanical,and straightening/painting workshop,from time to time i may experience difficulty with mechanical issues,so will be in contact with you again,

thank you

robert its me again,decided to replace the engine,just installed a used engine,with the same old transmission,but the engine not starting,may have overlooked something small,proberly a wrong connection,what can you suggest that i look for to rectify this problem



If its was running in the donor car then it could be the immobiliser thats not allowing it to start up / also ensure all earths have been connected - if its the same engine code then it might be worth considering swapping all the electrical components/inlet manifold etc from the old engine over onto the other one that been fitted - also check to see if its getting a spark and fuel upto the engine sometimes if you spray easy start into the intake then this will narrow down wether its either of the two..
