Which Engine Is in Your 4Runner

Four cylinder 4Runners carry the 2.7L 3RZ-FE and the V6 trucks carry the 3.4L 5VZ-FE. Most parts on this page are listed for one engine or the other. A few, like the oil hole cover gasket and the billet oil caps, fit both.

3RZ Oil Pump, Pan, Pickup and Dipstick

  • 3RZ Oil Pump Cover and Rotor Kit: cover, rotors and O-ring together. The rotor set and the OEM cover are also sold on their own, and LC Engineering recommends replacing the cover any time debris has been through the engine or after a failure.
  • Oil Pump Cover Allen Head Hardware Kit: replaces the factory Phillips screws, which wear and strip every time the cover comes off.
  • 3RZ Oil Pan: replacement for OEM 12101-75050, listed for the 2.7L 4Runner through 2000.
  • OEM 3RZ Oil Pickup Tube: OEM 15104-75050, for the 1996 to 2000 3RZ 4Runner. If you are rebuilding and keeping the factory pan, a new pickup is cheap insurance against old debris finding its way into the new engine. Seal it with the OEM pickup tube gasket, 15147-75020.
  • Oil Dipstick for the 1996 to 2000 3RZ 4Runner, for a bent, broken or missing factory stick.

For race builds there is a custom 2RZ/3RZ dry sump pan made to suit the application, and a CNC machined oil filter adapter inlet plate that blocks off the factory filter adapter with a 1/2" NPT port for your own plumbing.

5VZ Oil Pump

The 5VZ Oil Pump is a new, OEM quality pump for the 1995 to 2004 3.4L. It comes without gasket or seal, and the front seal is sold separately. It does not fit the T100, which uses its own pump.

Oil Filters, Remote Mounts and Gauge Plates

  • K&N HP-1002 oil filter: listed for both the 3RZ and 5VZ 4Runner, with a 1" nut welded to the canister so it comes off with a standard wrench.
  • Oil Filter Remote Kit: moves the filter somewhere easier to reach, adds oil capacity and frees up room in a swap. Universal, and it takes 3/4"-16 thread filters such as the Fram PH8A.
  • Oil Filter Adaptor Plate: an aluminum sandwich plate with four 1/8" NPT ports for oil pressure and temperature senders, with no drilling or tapping.

To finish the engine bay, LC Engineering makes billet aluminum oil caps in black and cog style, CNC machined from 6061 T6 and shipped with a new O-ring, and HPS makes an anodized billet cap as well.

Rebuilding the bottom end? The timing components for this truck are next door, the 3RZ oiling and 5VZ oiling pages cover each engine across every truck it came in, and the rest is in the 1996 to 2002 4Runner engine section. Not sure which part you need? Contact our tech team.
