Hi Again,

Sounds odd

Often when the pistons hit the valves on this engine the exhaust cam can rotate relative to its sprocket, it is only an interference fit. The inlet cam never does this.

If you put a drill bit into the oil way adjacent to the sprocket and then count the number of teeth round to the timing mark you should have 12 to 13. Looking at your last picture where you can see both the oil way and the timing mark it looks about right.

In my experience if the cam rotates then it tends to rotate quite a bit ie 90 degrees not 1 tooth.

Have you definitely got the right cams in your engine the manuals and autos have different cam shafts if you fit the wrong ones then you will have great difficulty starting the engine. Runs ok once started though and will start on easy start.

The exhaust camshaft sensor pickup profile is dramatically different on the manual relative to the auto.

If your engine is now back together and have a friend with the same engine and transmission then time them both up using the mark on the inlet cam sprocket then take out the exhaust cam sensor and look down the hole.

On the manual (I think) you should see an edge on the cam shaft pointing straight up at 12:00 oclock check they are both the same. If you have the auto (could be the other way round) then you will just see a smooth curve, rotate each engine round a tooth at a time and check the arrival of the edge is the same on both engines.

Hope this makes sense

cheers

Ben
