Rod knock, excessive oil consumption, or a seized Theta II or Nu engine? As dedicated Hyundai engine specialists we supply and install blueprinted long blocks that correct the factory design issues — so the problem doesn’t come back.
If your Sonata, Santa Fe, Elantra, or Tucson is showing a persistent rod-knock ticking noise, burning more oil than it should, or has thrown a low-oil-pressure related code, you're likely dealing with the well-known Theta II or Nu engine failures. In many cases the block is damaged beyond a simple repair. As Hyundai engine specialists we replace the factory-flawed components most commonly linked to repeat failures, so your new long block is a corrected version of the original — not just a like-for-like swap.
We stock long blocks for these Hyundai models: Sonata, Santa Fe, Elantra, and Tucson, covering engine families 2.4L Theta II (G4KE/G4KJ), 2.0L Theta II Turbo (G4KH), and 2.0L Nu (G4NA/G4NB).
