1. After disassembly and modification of the main oil gallery, technicians should carefully clean all RTV from mating
surfaces using care to avoid scratching or gouging any mating surfaces. Spray degreasing solvent through all
oil gallery passages from the underside through the piston cooling jet access holes to clean any debris from galleries.
Caution:
2. If desired, chase all threaded bolt holes for the cylinder head bolt holes and the main cap bolt holes using cleaning
thread chase taps. Avoid using thread cutting type taps to clean threads. Thread cleaning taps are
available through sources such as ARP, Snap‐on, or Mac Tools for SAE and Metric thread sizes.
Caution:
3. Clean the engine block prior to honing using either of the following methods;
a. Clean in the spray booth using degreasing solvent followed by a 50/50 solution of EF‐411 and Degreasing Solvent
followed by air dry using clean dry compressed shop air.
b. Clean using the Ultra Sonic Cleaner following the manufacturers recommendations followed by a water rinse
and spray with a 50/50 solution of EF‐411 and Degreasing Solvent followed by air dry using clean compressed air.
Note:
If cleaning the block in the Ultra Sonic Cleaner, install M12 x 1.5 50mm long bolts with M12 nylon oil drain plug type
washers snugly into the cylinder head bores to prevent the Ultra Sonic Cleaner solution from leaching out the
lubricant on the threads in the block to prevent bolt chatter during the cylinder head fastener torquing procedure.
4. Clean and inspect the cylinder head fasteners from the New Engine Disassembly.
5. Lightly oil the cylinder head fasteners with EF‐411 and allow to drain all excess oil from the threads using clean
Teri towels before installation of cylinder torque plates.
6. Clean and lightly oil the main cap fasteners and side bolts using EF‐411 allowing all excess oil to drain from the
threads using clean Teri towels.
7. Cylinder head gaskets are Multi‐Layer Steel gaskets. The cylinder head gaskets removed during the New Engine
disassembly can be re‐used with the BHJ Torque Plates and spacers used to position the fasteners at the correct
bolt drop in the cylinder block.
8. A good practice for build technicians is to ensure there is no oil or debris in the blind threaded bolt holes before
assembling the main caps or cylinder block torque plates using compressed air or blotting with absorbent materials.
Note:
Technicians should prep the cylinder head fasteners and the main cap fasteners prior to installation by wiping the
threads between folded sections of an EF‐411 saturated "Lint Free" rag during fastener installation.
See the materials section of the IIIH Engine Assembly Manual for suggested supplier information on Lint Free Rags
that have been found suitable for use by the test labs.

Technicians should exercise extreme caution while cleaning mating surfaces of the engine block. Use only
plastic type non marring scrapers for removal of RTV and other debris from mating surfaces. Visual
imperfections on the cylinder deck and other gasket sealing areas may remain even after removing RTV.
Non compressible debris such as oil, coolant, or RTV sealants not removed from bolt holes can cause the
aluminum cylinder block to fracture when tightening fasteners.
