According to Au7o's research across NHTSA recalls, manufacturer TSBs, and owner forum reports, the 1998 Acura RL has 2 documented known issues, with 1 rated critical. The most serious is Timing belt + hydraulic tensioner replacement at 90k mi / 72 months — interference engine ($1,400-$2,800 repair). Across all issues, repair costs range from $150 to $2,800. DIY maintenance guides at au7o.io.
On the 1996-1999 Acura RL 3.5L V6 C35A, the first-gen RL's 3.5L C35A V6 is part of the Honda C-series V6 family, which is widely documented as interference design (valves and pistons share rotational space, separated only by timing belt synchronization). The published timing belt interval is 105,000 miles or 84 months per the maintenance schedule. The hydraulic timing belt tensioner on this generation has been reported by independent shops as a known failure point: the internal oil seal leaks, the tensioner loses pressure, the belt can jump a tooth or two, and valves can hit pistons. Multiple sources caution that aftermarket tensioners have a worse failure rate than OEM Honda or Aisin — pay for the OEM-equivalent kit. Note: belt replacement intervals are sometimes quoted as shorter (90,000 mi) by independent shops as a conservative buffer, but the manufacturer-published interval per Acura is 105k/84 months for this engine family.
Common Symptoms
Squealing or rattling from front of engine (tensioner bearing or pulley)
Coolant leak from timing cover (water pump weep)
Oil pooling at base of timing cover (failed crank seal)
Engine cranks but doesn't start after belt jumps a tooth
Loud metallic clatter on cranking (valves striking pistons after belt failure)
How to Fix
Replace the timing belt + hydraulic tensioner + water pump + all front seals + idler pulley as a complete kit. Aisin sells a TKH-022 complete kit covering all of these for ~$200-300 — vs $1,200-1,800 in labor at an independent shop. Insist on the OEM Honda OR Aisin tensioner specifically — cheap aftermarket tensioners are the #1 cause of premature post-replacement failures on this engine. Total at indie shop: $1,400-2,000. Dealer: $2,000-2,800. Never use a generic 'timing belt only' service — replacing the belt without the water pump or tensioner is a guarantee of a second teardown within 30,000 miles.

UpgradeAisin TKH-022 complete kit (belt + water pump + tensioner + all front seals + idler) — $200-300. The OEM-grade option that doesn't fail like cheap aftermarket kits do. (Aisin Acura RL C35A Timing Belt Complete Kit)
NoteAftermarket tensioners (Continental, Dayco, no-name imports) have higher failure rates than Aisin or OEM Honda on the C35A. Pay the extra $40 — the labor cost dwarfs the parts price.
TipNever accept a 'just the belt' service quote. Replacing the belt without the water pump or tensioner is a 30,000-mile-deferred second teardown. Do it all once.

On the 1996-2004 Acura RL 3.5L V6 C35A, like every C-series V6 Honda used in the 1990s and 2000s (Legend, NSX, CL, TL, RL all share the family), the RL's 3.5L C35A V6 has a distributor mounted at the back of the head and driven directly off the camshaft. Inside the distributor housing, an oil seal isolates the cam-driven shaft from the cap/rotor/electrical assembly above. By 100,000 miles the seal hardens, oil pressure forces engine oil past the shaft, and the cap fills with oil. Result: misfires (typically P0300 random plus individual cylinder codes P0301-P0306 since this is a V6), rough idle, hesitation. RepairPal explicitly lists distributor O-rings as one of the most common Acura RL oil leak points. The figure-8 oil cooler seal and oil filter housing gasket are the other two common leaks on this engine — diagnose carefully before assuming distributor. The C35A engine remained in the first-gen RL through the entire 1996-2004 production run, so this issue affects all years.
Oil pooling inside the distributor cap when removed
Engine misfires, especially under load or after warm-up
Check engine light with P0300 random misfire or P0301-P0306 single-cylinder
Rough idle that smooths out with throttle
Visible oil at the rear of the engine, dripping down the back of the block
How to Fix
There is no replaceable seal inside the distributor — the seal is between the rotating shaft and the bearing inside the cast housing. The only fix is replacing the whole distributor assembly. OEM Honda runs $400-700; Cardone remanufactured runs $150-250. While the distributor is out, also replace the distributor cap, rotor, and ignition wires — they're cheap and you're already at the parts. Inspect the cap and rotor on the old unit for oil contamination to confirm distributor was the source. If you also see leaks elsewhere (figure-8 cooler seal, oil filter housing), address those at the same time — they share access path. Total job: 2-3 hours independent shop.

TipReplace cap + rotor + ignition wires at the same time as the distributor. You're already there. Saves a future labor cycle.
NoteDon't assume distributor without inspection. RepairPal also lists the oil cooler 'figure-8' O-ring and oil filter housing gasket as common RL leaks. Pull the cap and check for oil before buying the distributor.
