Feuling 4098

7/16-20 Replacement nut for Feuling Quick install pushrods #4096 and #4097
CORRECT PUSHROD/LIFTER ADJUSTMENT REQUIRES STARTING WITH FULLY PUMPED UP LIFTERS!

QUICK INSTALL PUSHRODS HAVE 7/16-20 THREADS PER INCH, 0.050 ADJUSTMENT PER TURN. 2 TURNS = 0.100

TROUBLE SHOOTING NOISY VALVE-TRAIN
1. Lifter adjustment - Starting with a fully pumped up lifter, from zero lash put 0.90 - 0.100 of pre-load on Feuling hydraulic lifters
2. Lifter to lifter bore clearance out of spec, Feuling recommends a clearance of 0.001 - 0.0015 for proper oil psi at lifter
3. Pushrods flexing and hitting pushrod tubes - look for a shiny ring witness mark around pushrod normally seen up towards the cylinder head
4. Low oil pressure - inspect pressure relief valve in camplate, oil pump/camplate wear
5. Pushrod center oil hole plugged
6. Clearance for roller rocker arms on under side of rocker box covers
7. Steep ramped camshafts, valves closing so fast the valves bounce off valve seats - see Feuling Beehive valve springs
8. Excessive crankshaft runout
9. Gear drive camshafts, excessive gear drive backlash or excessive crankshaft runout
10. Rocker arms/bushings out of tolerance
11. Valve spring clearance to lower rocker box housing
12. Valve spring coil bind and or valve spring harmonics - match up valve spring open height with camshaft peak lift
13. Leaky/broken piston cooling jets
