hlava motoru, pár rad??

[soptik]

zdravim, mám pár dotazů ohledně 300 motoru.
u ventilu rupla hlava, tak je momentálně ve švařovně.
za prvý, hlava byla neuvěřitelně přetažená, šrouby se povolovaly pomocí trubky.. odhadujem, že tím došlo k rupnutí??? nebo je to nešvar těhle motorů???
a za druhý jaký maj bejt ventilový vůle??? dotažení hlavy sem v manuálu našel, ale ty vůle ne....

díky za rady Jirka

VALVE CLEARANCES - ADJUST
CAUTION: To prevent possibility of
damage to cam follower seatings, it is
essential that ball ends of tappet adjusting
screws are seated in recess in push rods and
that ball end of each push rod is correctly
located in cam follower slide.
1. Rotate crankshaft by means of crankshaft
pulley bolt in a clockwise direction until number
8 valve ( counting from front of engine ) is fully
open.
2. Using feeler gauges and a screwdriver, adjust
clearance of number 1 valve.
Valve clearance - all valves = 0.20 mm
3. Tighten tappet adjusting screw locknut when
clearance is correct.
4. Adjust the remaining valve clearances in the
following sequence:
Adjust number 3 clearance with number 6
valve fully open
Adjust number 5 clearance with number 4
valve fully open
Adjust number 2 clearance with number 7
valve fully open
Adjust number 8 clearance with number 1
valve fully open
Adjust number 6 clearance with number 3
valve fully open
Adjust number 4 clearance with number 5
valve fully open
Adjust number 7 clearance with number 2
valve fully open
5. Upon completion, re-check all clearances and
adjust as necessary.
