Owner of a 1994 f-150 i’m considering buying for super cheap sent me a video of the truck starting up and giving a few revs. He says the motor is a 302 5.0. I can hear from when he starts the car and revvs it, it sounds like there’s a bit of a knocking or rattling noise as you can hear from the video. Would you all steer clear of this? He said it runs and drives. Does this sound like a lifter, rod knock, exhaust leak, etc. thanks > **[1994 ford f-150, 302 5.0 v8 motor.

It sounds like timing chain rub. This truck may have the silent cam timing gear. Which means the teeth on the gear made from plastic. Tester ---

Sorry, unable to listen to vdo. But I own a 302 equipped 50 year old Ford truck, never had start-up noises as you describe, but have some experience w/engine at least. For rattling noises on start-up, if nothing obviously wrong, like pulley or belt is hitting something, my first suspect would be a loose/worn timing chain. Water pumps on my version of this engine, when they are about to fail, can make rattling noises too, usually worse until coolant warms up. A length of garden hose can be used as a stethoscope to narrow down if the sound is coming from water pump or not. Water pump relatively easy & inexpensive to replace. Timing chain, not so easy. One more idea, if ignition timing considerably too advanced, that can sound like a rattling noise. It’s actually not something rattling, it is pinging coming from the cylinders. I had that problem briefly one time when I got the vacuum hoses to the distributor mixed up. ---

With the timing chain rub you’re talking about - is failure in the very near future almost guarantee? ---

Only if you continue to operate the engine if it isn’t repaired. This is the silent cam gear with the plastic phenolic teeth. ![image](https://global.discourse-cdn.com/cartalk/original/3X/4/a/4ad7bb801d0090d30cfb3668b2aeb9d3e08f3b6f.jpeg) Tester ---

So the truck is already flirting with 30 years old, there’s a suspicious internal engine noise…and you’re still considering buying the truck? I’d keep looking.
