Anyone really interested in this issue should check out the type2 archive, where this issue was well hashed through, recently. However, I can quickly rehash a few points: (1) The the type 1-3 engine was not designed for hydraulic lifters, as James MacNaughton pointed out, and there are plenty of people out there who have had bad luck with them. Some places that do the conversion rework at least some of the oil passages, as I recall, and probably use a different cam, heavier valve springs, and maybe stronger pushrods too. The Type 4 engine had hydraulic lifters from '77 or '78 on, and got all of these other goR&¦ë hough the case remained the same -- I don't know if it was designed with their future use in mind). I believe that at least some of the Mexican type1-3 engines came/come with hydraulic lifters, but I don't know the details on this (again, for this and other non-type3-specific acvw info, try searching at http://vw.i405.com). (2) Hydraulic lifters not only wear out, like solids; they also fail. (3) Adjusting your valves keeps you apprised of the state of your engine, so you have some advance warning if a valve is stretching and about to pop its head to dance around in your cylinder. Also, it gets you down under the vehicle, where you'll notice that your cv joint is attached with only 3 bolts, and the gas line looks pretty dodgy. Oh, and helps you bond with your type 3! (4) Quieter? Yes, but if that's what you want .... Hey, the solid lifters sound more like an old VW.
