I am due (2nd time) on my 2003 Passat 1.8L for the water pump/timing belt at 185k miles.
That whole front end thing tear out is sissy work (very, very do-able if time is not an issue). On the up side, after the sissy grunt work, you have outstanding access. I'll take that over tearing your forearms up on a 1.8L Turbo Beetle for the same job.
Buy the metal water pump from ECS Tuning. It ain't the timing belt that will go.
Now, coking. Yes, Sir. That probably will happen.
Switch to a heavier oil and at every oil change use a "flush" for a few minutes to start to break down the crud.
I have 30k of bonus miles since my first oil starvation warning.
When I say switch to a heavier oil, I mean like what you would use in your early 80's 911. Castrol 30W-50.
This is not based on science, it's based on experience.
