If you guys really want the engine to live, stay solid lift, leave the hydros alone..

We refuse to build hydro engines, as we see so many die every week. I know adhjusting 9144 valves is no fun, but neither is losing a cam at less than 40K miles, or not finding that stretched valve during a valve adjustment....

Doing this everyday, 16+ hours/day has taught us something, that the law of averages is against the hydro engines.

Dirty oil is rough on lifters, which will grenade from contamination within their tight tolerances, also thos lifters bleed down, and really pound the valves into the seats when the engine has sat for a few days, helping to loosen seats and prepare for destruction..

The ONLY 914 engine I have ever seen drop a seat, had been converted to hydro< FYI...

Everytime I post this info, I catch a hard time for it, fact is fact, and I stand behind it 100%...Even if it defys conventional wisdom.
