Well....same ole same ole :p
I am rebuilding the Top End on #3032 the Last 1990 ZR-1 sold to public (57K miles).
Everything removed/restored/replaced on Top End (Plenum, Secondary Vacuum system, HVAC Vacuum, Plugs, Coils, Starter, Crank Case Vent Cover, Alternator, AC Compressor (not disconnected).
This is my standard Top End Restoration.
This time I will leave the Water Pump as there are NO leaks at all and ALL bolts were tight.
1. Replaced Power Steering Pulley with Billet Aluminum Pulley.
2. Replaced Belt Tensioner Pulley with Billet Aluminum Pulley.
3. Replaced Crank Case Vent Cover Gasket (several loose bolts - use Red Loctite).
4. Replaced Aftermarket Spark Plug Wires with LT5 Original Plug Wires.
5. Blocked TB Coolant at Injector Housing (appearance is as stock).
6. TB Coolant Return Line to Coolant Surge Tank Blocked.
7. New Spark Plugs.
8. New Secondary Port Throttle Linkages.
9. New RC Injectors (SL4-205s).
10. New Primary and Secondary Injector "O" rings.
11. New Plenum Gasket (use NO gasket sealant of any kind as there is NO Coolant.....Dry Gasket- NO Loctite).
12. New Crank Case PCV "L" hoses under Plenum.
12. Reconditioned Vacuum Canisters (shined up).
13. Reconditioned Starter Solenoid (wire brush contacts on plunger).
14. This time I had to replace bearing on Solenoid end of starter armature (it was a bit rough).
15. New Radiator Hoses with rounded edge clamps.
16. Checked all Coils for proper and consistent resistance.
17. Reconditioned Coil Plate (shined up).
18. Checked Alternator Bearings and shined up Alternator.
19. Replaced Fuel Line "O" Rings at Connection Rear Passenger Side of Plenum.
20. Replaced Injector Housing Coolant Manifold Gaskets and bolts (Use Heat to remove original Torx bolts).
21. Checked ALL Injector Housing Bolts for tightness (Did NOT remove Injector Housings as there were NO oil leaks).
22. Used light Steel Wool (0000) and Simple Green on Plenum and Cam Covers (Will leave Stock Look without Painting or Powder Coating).
23. Removed cover (six 4mm Torx 20 bolts) and dried out TB Coolant Area above TB. Will Replace this cover with Carter Billet Aluminum (ZR-1).
24. More when I think of it ;) (takes three days......one day to disassemble, clean, and repair broken parts, one day to think, and one day to put back together and fire it up) :D
NOTES:
Everything Degreased and HOT WATER Pressure Washed when TOP END Disasssembled. This included clearing the Valley Vent through Bell Housing.
Oh....LT5 ran great (I thought) but found four bad Injectors (resistance 10 ohms, 10 ohms, 6 ohms, 6 ohms)
Compression checked earlier and ALL Cylinders 215 lbs within 5 lbs.
ALL Fluids were Replaced (Engine Oil, Transmission Oil, Differential Oil, Coolant) and Differential Drain Plug Installed Earlier. Haibeck Chip and Starter Relay were also installed earlier.
Typically I check and locate ALL vacuum leaks on secondary system but this LT5 had NO Vacuum Leaks (Secondary Canisters functioned perfectly BEFORE Start of Top End Restoration).
