and what about if you just do timing belt and head gasket would you recomend waiting/ giving time for breakin before hauling on it??
on a brand new rebuild motor I1) change oil and filter with engine warm after it gets operating temp. gets rid of assembly lube and any missed crud from cleaning.2) drive it on a curvy back road that gives me the accel then decel in 3rd or 4th gear(driving like I stole it) for maybe 50 to 100 miles, checking for any leaks or problems (watch gauges). Change oil and filter adjust valves.3) Drive it like I stole it from then on.I belive in breaking the motor in how you are going to drive it. Race engines get some dyno time then hit the track at WFO throttle. I finally got over 50 mpg on my 98 Jetta TDI, at 255k miles, hmm it's still getting better mileage, guess the motor isn't broken in yet. :lol:
but it is the EGR system that really gunks those engines up, negating any benefits...
