Hydraulic vs. Solid Lifters

Recommended Posts

I am rebuilding a P90A head from an L28 turbo and was confused when I came across the hydraulic lifters. I have not seen these before on a cylinder head so I am wondering what people think about them. I've seen videos of people who do conversions to solid lifters using time-serts but am not yet sure if I want to invest in this. Is it worth it? The hydraulic lifters I currently have seem pretty solid with no play in the pivot. It would be great to hear any thoughts or experiences regarding these hydraulic lifters. Thanks.

There's a procedure for testing them.  They're called pivots.  I've only read of a few problems with them, they can wear out.  You can probably replace them without removing the head, engine in the car, if you have to.
