BMW Engine tapping. 93 318i 4cyl M42

I just got finished replacing all the lifters and replaced the timing chain tensioner. This did not fix my problem with the engine noise.
When cold, the engine sounds fine, little tapping. After it warms up, sounds like a diesel. Please give me some ideas. This is driving me crazy! Click the link to watch and listen to what Im talking about.

Update: The problem has been resolved.
When we removed the oil pan to replace the oil pump, there was shrapnel from the old timing chain guide. (previous owner had that replaced)
They were large pieces too. They was getting sucked up to the sump pump screen and restricting the flow of oil to the top of the engine. Purred like a kitten after the new oil pump and removing that crap from the oil pan.

These engines require 15w-40 oil. Same motor oil as the put in diesel engines.

The problem ig you have the clicking noise is going to be 1 of a few things.

Replace the timing chain tensioner 1st. This isnt that hard to do.

You may need a new timing chain and rails, if this has never been replaced.

When it does get replaced, make sure the mechanic removes the oil pan and cleans the oil pan. particles will get dropped down there when the timing chain rails get chipped up by the chain.

If you are a DIY kind of person, join the

M42 club. Can get a lot of free help from that group. There are other BMW forums online to join as well. People share knowledge and photos that really help. Google search M42clu & BMW forums. That will help you. Good luck!

Also, all M42 owners should check their lower oil pan periodically for loose bolts that have fallen out of the upper oil pan ESPECIALLY after you buy a car from another owner. The lower isn't such a PIA like the upper, only a 30-minute job for even an amateur mechanic. Make sure you replace the gasket every time you take the pan off.

Here in the uk we run 5w-40 oil and thats the chain tensioner.

Yes we did. When we removed the oil pan to replace the oil pump, there was shrapnel from the old timing chain guide. (previous owner had that replaced)

They were large pieces too. They was getting sucked up to the sump pump screen and restricting the flow of oil to the top of the engine. Purred like a kitten after the new oil pump and removing that crap from the oil pan.
