Anybody out there had any experience with using hydraulic valve lifters (like those from Weber Camshafts) in a 914 2.0L four? This seems to me to be a good way to eliminate the hassle of manual valve adjustments on 914 four cylinder engines. All and any info greatly appreciated. Thanks.

How can that be? There is a vast sea of cars driving these days that have hydraulic lifters - are there no good ones that can be used in our engines? Is the problem caused by poor manufacturing of the hyd lifters that are currently available for these engines? Is the oil system not compatible with hydraulics? I'm confused at why this is a problem.

QUOTE(Last930 @ Nov 13 2014, 11:55 AM)  How can that be? There is a vast sea of cars driving these days that have hydraulic lifters - are there no good ones that can be used in our engines? Is the problem caused by poor manufacturing of the hyd lifters that are currently available for these engines? Is the oil system not compatible with hydraulics? I'm confused at why this is a problem. Think of a hydro lifter as a cup pf beer. (IMG:style_emoticons/default/beer.gif) (Mmmmmmmm, beeeeeeeeerrrrrr) In 99% of engines, these are in a "V" or vertical "I" engine and the cup is upright so it's difficult for the oil inside to come out. In our engine's the cup has tipped on its side and when a car is parked for an extended period of time, the oil runs out (loosing it's prime). What results is the sound of 8 midgets with jack-hammers when you start the engine. Depending on (1) how often the oil was changed throughout it's life, (2) how much wear has occurred in the lifter bores/lifters, (3) what weight oil you run, (4) how much oil pressure your pump makes, etc, etc. this momentary lack of oil in the lifters can linger on for many minutes. It sounds so bad that I've had clients tow their vehicles in thinking the motor was toast. I once had a Vanagon (IMG:style_emoticons/default/barf.gif) that took 15 minutes at hwy speeds to finally pump-up the last lifter!!!! There is also a big lack of performance cams readily available for hydros. Who wants to run a cam that is just one step off of stock?? Other than the stuff mentioned above, they're great!!
