To find cylinder 8, you'll need to find the firing order for your specific engine. This information is crucial because the cylinders aren't always arranged in a simple 1-8 sequence around the V. You'll likely find the firing order:
* In your owner's manual: This is the best place to start.
* On a sticker under the hood: Sometimes manufacturers place a sticker with engine specifications, including firing order.
* Online: Search for "2002 Ford Econoline E150 [engine code] firing order," replacing "[engine code]" with your engine's code (found on the engine itself).
Once you know the firing order:
1. Locate the number 1 cylinder: This is usually the cylinder closest to the timing cover on the passenger side (right side, facing the engine).
2. Follow the firing order: Use the firing order sequence (e.g., 1-3-7-2-6-5-4-8) to locate cylinder 8.
Without knowing the specific engine code (which is stamped on the engine block itself) and the firing order, it's impossible to give you the exact location of cylinder 8.
