Good point, Dillers. No modifications should be made to an L36 until:
1. The upper intake manifold is replaced with a Dillon, APN, or Dorman replacement including a reduced-diameter stovepipe.
2. LIM gaskets replaced with aluminum framed design from INTENSE, ZZP, or GM.
3. Fully flushing the DEX from the engine, and replacing it with Dex compatible prestone long-life.
Failure to follow the above advice will eventually result in your car failing you at a very important time, or costing you your entire engine.
