Will thicker oil stop lifter noise?

If the oil is too thick then it will not pass through the tiny holes resulting in an increase in friction. The increased will not only lead to noisy lifters, but it may also increase the temperature a little bit. On the contrary, if the oil is too thin, it won’t provide proper lubrication as well as padding.

Can you replace lifters without removing heads?

You do NOT have to remove the heads to get the lifters out. You simply remove the cam without putting anything in the block to hold the lifters up. The lifters will fall down on their own after a while.

What causes a lifter to get stuck?

There is a tiny valve on them that allows oil in. When the vehicle has not been run for a while, or runs low on oil, the lifters will loose oil. As oil pressure build up, they will ‘pump up’. So the issue is not that they are sticking, it is that they are compressing all the way when usually they do not.

Can you drive with a stuck lifter?

If it is indeed a lifter (Does the 1.8 Audi have lifters?), then it would be OK for a while. But until that is determined, I wouldn’t drive it. If it is a bearing on the crankshaft or cam, then it would damage it by driving it further. If it’s a turbo problem there may or may not be a performance hit….
