My car had developed a rattle over the last few days comming from the, from stood at front, left hand head.

Would start off fairly loud, and get quieter when engine would warm up. Fearing the worst I started to look at new heads etc etc.

Finished early today, So I decided to have a look, and take the cam cover off. With the engine warm, it wasnt making a sound, untill I put the ratchet on the top left hand bolt, and moved the casing MM's to the right...and rattle..

Sooo..Is this normal for the casing to shift? I take it that its just rubbing on the cam wheel, and being made of metal, expansion when warm so no rub, but rub when cold.

Just replace the bolts/rubbers or more than that?
