Could somebody show me some pictures of the timing marks on the 3.0lt V6 engine please. I can't find my spanish friend and wont be able to get a Cambelt DVD in time for the weekend so i can check my cam timing. I know the pulleys have more than one mark on them but i can't remember what each mark corresponds to.
TIA :y

You need a cam locking/timing kit to check it properly ;)
-
As said, the only possible way on a v6 is with the proper timing kit
-
I have a locking kit but i'm not sure about the marks on the cam wheels, aren't there 2 sets of marks on them ? I need to know which ones it should be timed to so i can check that everything is as it should be.
-
They are marked inlet and exhaust, just line them up to the appropriate mark with the notch at the top of the rear cover.

On V6, use the marking for that camshaft, with cam 1 being the left and cam 4 being the right.

On a v6, you need to use the timing tool, the markings on rear cam cover are approximate :y

So you're just checking that everything is as it should be on an engine that runs OK? If that's the case, then whatever marks line up are the right ones! The pulley marks are so far apart that if the cams were timed to the wrong marks the engine would run like a pile of crap, if at all.

The lads that do work on various cars will tell you that it's very common to find cam belt that was fitted a tooth or two out. These cars appeared to run OK before hand, but obvioulsy better afterwards.

The point I was trying to make was that the 'wrong' marks are so far round the pulleys that even if the timing is not spot on, even a whole tooth or two out, when you turn the engine to TDC, it will still be obvious which are the correct marks as they will almost line up. Having just been out to check though - seems that's only true for two pulleys, the marks on the other two are only 4 teeth apart, so in theory you could be two teeth out on those and be between the two marks and not know which way to go to correct it. In other words ignore me :)

Who??? ::) ::)
I made a paint mark on the appropiate cam pulley marks when I did mine ....... just to be on the safe side :y :y :y
