I have a strange problem with my 306, its a 1998 1.6xs, and has recently had the head gasket replaced because of an oil leak, it is currently on 64,000, which is now sorted, and it doesnt leak. The problem i have is whenever the engine is hot, or i am parked on a hill, the engine sounds really tappety, but it is not always like this only sometimes, it stays like this for a while. Then some days it sounds alright, the tapping noise sounds like it is coming from the top of the engine, it is a strange problem as it doesnt happen all the time. I am using good oil in it as well Castrol Magnetec, 10w/40, as i thought this may help, as i was unsure what oil was put in when the head gasket was done, but after the oil, change i am getting the same rough tappety noise.
Any ideas of what this could be, or has any one expireenced this on a peugeot before
Thanks
