does a cam belt failure on a 200 tdi disco result in valve damage or are they non damage engines..thanks..robbie
-
just push rods peice of cake to do
-
I had a cambelt break a couple of weeks ago on a 200tdi, the result was 8 bent pushrods and 1 broken rocker! They dont normally bend valves as the valve stems are harder than the pushrods and the valve heads are parallel to the pistons so they hit square on the pistons.
If you have any broken rockers make sure you recover all the broken pieces as a bit of mine fell down the pushrod hole, tried magnets and every thing i could think of to get it out ended up taking the head off it was a propper pain!

i done the cambelt in mine not so long ago. i have never replaced 1 b4 let alone replaced a broken 1 and it was a piece of cake. dont listen to the garages when they say the eng is shot. i done the head gasket (didn't really need doing but wanted to look at the valves) cam belt and water pump and all the bits came to less than £100

thanks lads,,,forgot to ask but just need any advice or pointers on how to set timing back up now then... :oops:
-
mark the pulleys with tipex,put the new belt on and line up the marks,or borrow a proper pin kit that pins and holds the cam and pump sprockets,crank mark is the key way,mark that too, :)
-
I cant remember exactly where all the marks are but i made a tool to hold the fly wheel this was a wading plug with (i think) A 3/16 hole throuh it then use the drill bit as the timing pin for the fly wheel and the wading plug to hold it in the middle. there is a hole in the injection pump sprocket which will take a larger drill bit (about 8mm i think) and the other 1 has a mark on the pully and a arrow on the housing from what i can remember just to the left of it near a bolt hole.
hope this is of some help
Cheers Rob

Put a 9.5mm drill bit through the injection pump at about the 11 oclock position to lock it, the woodruf key on the crank lines up with a cast arrow on the timing chest at the 12 oclock position and the cam pully has a dot mark on it that lines up with a web on the timing chest at about the 7 oclock position if that makes any sense to you!!

not one of your's is it
-
the hardest part of this job is getting the bottom pulley off!!!!
-
