*FOR HONDA MODELS USING VVT VALVE 15810-R70-A04 - This Odyssey is a 2008 Touring Model with brittle gaskets in the VVT Solenoid Spool causing considerable oil leaking down the side and front of the engine (area of the alternator and camshaft timing belt) and dripping of the bottom near the serpentine belt tensioner.
*Honda VVT Solenoid Spools are known to develop oil leaks with age. The VVT Solenoid Spool is generally located on the head of the engine. In this case, it is right at the oil dipstick. Various vehicle models and engines will have different types of VVT Solenoid configurations. This one has another VVT on the rear engine head at the opposite corner.
*The Touring Model may have a different VVT Solenoid than the LX and EX Models. Use your vehicle VIN number to look up the correct VVT parts for your vehicle.
