LT5 Tool Kits

Jeal Enterprises is proud to introduce a new product line. In the past there 
was only one source for the expensive specialty tools required to work on our 
ZR-1 engines, but now that has all changed! We are now offering two new kits. 
The difference with the Jeal kit is the tool quality and price. The pricing is 
based on using the Kent-Moore's 1998 Jobber or Wholesale price sheet. The prices 
reflected are ONLY 70% of the 1998 WHOLESALE PRICES! Check it out. 

The first kit is what we call a "TOP END" kit. The tools in this kit will allow a 
person to install and degree camshafts. The tool assembly includes:

Part Number     Description                     Cost
38098   Crankshaft Timing Slot Locator          $109.33
37305   Camshaft Chain Pre-Tensioner            $ 71.47
37326   Camshaft Timing Alignment Pin Set       $ 60.94
41009   Chain Tension Unloader                  $ 25.80
37303   Camshaft Temporary Retainer             $ 84.77

TOTAL "TOP END" KIT                     $352.31

Note: Kit does not include a degree wheel or dial indicator necessary to degree 
camshafts.

The second kit is the "LT5 Overhaul tool kit", it includes all of the tools 
listed for a "TOP END" kit plus the following:
 
37306   Crankshaft Cup Plug Installer           $ 23.91
37309   Front Cover Aligner/Seal Installer      $ 39.66
37312   Crankshaft Rear Seal Installer          $ 47.04
38124   Cylinder Liner Remover                  $ 80.40
38132   Crankshaft Sprocket Installer           $ 29.89
38211   Crankshaft Sprocket Remover             $ 14.30
38837   Crankshaft Rear Core Plug Installer     $ 11.83
37328   Idler Sprocket Bearing Press Tool       $ 42.56

camshafts.

LT5 Exhaust Manfolds

This is a service bulletin of information. It IS NOT a recall. 

It does not require GM to do anything for free to your car *unless* you have a failure of the exhaust manifolds or cats that is still under the 5/50000 emissions controls warranty. 

 

Subject: LT5 Exhaust Manifold Servicing 

Model: 1990-92 Chevrolet Corvette with 5.7L Engines (VIN J-RPO LT5) and 6 Speed Manual Transmission. 

 

When servicing the exhaust manifolds on 1990-1992 Corvettes with LT5 engines, use the following parts. These parts are the 1992 production exhaust manifold parts. Use the 1993 production exhaust manifold bolt pattern and torque specification. Plug the EGR hole on the RH (right hand) exhaust manifold with a 1/4 inch pipe plug. Tap hole approximately one inch down with a 1/4 inch pipe tap. See table below for pipe plug part number. 

 

 

Quan Part Number
Description
25129492  LH Exh Manifold 
25143612  RH Exh Manifold 
25129500  LH Exh Manifold Shield, Outer 
25129498  LH Exh Manifold Shield, Inner 
25034993  RH Exh Manifold Shield, Outer Rear 
25034884  RH Exh Manifold Shield, Outer Front 
25035039  RH Exh Manifold Shield, Inner 
10187776  Exh Manifold Gaskets 
16  10067660  Exh Manifold Bolts 
14  10110994  Exh Manifold Bolt Spacers 
03983422  Exh Manifold Bolt Spacers 
25129502  LH Ctltc Converter 
25129503  RH Ctltc Converter 
10174330  Converter Bolts 
12  09440166  Manifold Shield Bolts 
10137641  LH Oxygen Sensor 
10096129  RH Oxygen Sensor 
12338136  1/4-inch Pipe Plug 

 

 

Clearly, what is happening here is that GM-SPO has no more 90-92 manifolds and cats left so they are adopting a procedure of, when manifolds need replacement, updating to the exhaust manifolds for the four-bolt motors. That is a good update because the 93-95 manifolds are probably 10-12hp of the 30 more you got with the 93-95 405hp engines.
