You need to get that from the Ford dealer.

Have they heard the noise or just you? Not hearing the click myself, it is quite possible that the exhaust manifold gasket has a small leak due to improper torqueing, crack, defect, or warp. I would sound mechanical but is actually air and would be intermittent at the early stages. Just to make sure, get a flash light and mirror and examine the exhaust manifold assemble looking for grey or black powder. It is a long shot but could be the issue, as could be a flat cam lobe, sticking valve from a bent or damaged guide, or other unforeseen abnormal conditions such a crack in a bucket. You could try a super oil and see if it does not go away in a week. I have had them fix issues like this as well.

Generally, when foam exists in the radiator, you have combustion gases entering the coolant system, and the cause may be a bad head gasket or a cracked cylinder head and in some cases may be an intake manifold gasket leak. If you open the radiator cap (make sure its not under pressure) smell the air near the radiator cap opening while the engine is running and if it smells like exhaust fumes then you have the problem as I first stated.

Any codes?fuel filter.

My lists of interference engines does not list the 99 ford focus 2.0L engine. There shouldn't be any damage to engine.
