On the 1998-2003 Honda Accord, some 1998-2003 Accord engine blocks were cast with microscopic porosity in the aluminum, allowing engine oil (and in some cases coolant) to weep through the block casting itself. Because the leak is through the casting rather than a gasket, it can be hard to pinpoint and reappears after gaskets are replaced; severe cases show oil-in-coolant cross-contamination. Honda released a service bulletin covering 1998-2003 model years and has offered repair assistance on a case-by-case (goodwill) basis. RepairPal documents this as a recognized Accord powertrain concern.
Diagnose by cleaning the block, dye-tracing the seep, and ruling out gasket/seal sources to confirm the leak originates from the casting. Remedies range from sealing the porous area to short-block/engine replacement for severe cases. Pursue Honda goodwill assistance under the service bulletin. Many owners with minor seeps manage it by monitoring oil/coolant levels and keeping the area clean.

Honda's TSB fix for a porous J-series V6 block is to SEAL the seep, not replace a part — porosity is a casting void, not a serviceable gasket. Hondabond HT (made by ThreeBond, cross-refs to 1207B) is the OEM sealant used to coat the porous spot / sealing bolts. Withstands oil+coolant and ~315C. Veri
TSB seals porosity at bolt holes by coating an OEM flange bolt with ThreeBond/Hondabond and re-installing. 6x32 flange bolt PN 95701-06032-00 confirmed (HondaPartsNow $1.36, Partzilla, Amazon). Exact bolt size varies by leak location on the block; this is the commonly cited size. Often used WITH the

On the 2003-2007 Honda Accord, 7th generation (2003-2007) Accords are well known for backlight failure on the upper multi-information display (radio/climate-control info) and dimming or dead gauge-cluster illumination, where individual LED/bulb segments burn out and leave portions of the display dark. The condition was common enough that Honda issued Technical Service Bulletin 04-023. A blown fuse (commonly #23 IGP in the under-dash box) can also kill the cluster entirely. Beyond inconvenience, an unreadable speedometer/odometer at night is a real driving hazard.
For a fully dead cluster, first check fuse #23 (IGP) in the under-dash fuse box. For burned-out backlight segments, the display/cluster is repaired by replacing the failed LEDs/solder joints or installing a rebuilt cluster (specialty rebuilders ~120-300 USD) or a new OEM display unit. TSB 04-023 covers the upper-display backlight remedy for eligible vehicles.
