It sound like it may be pinging. Does it sound like a clattering noise. Later model Fords are prone to this condition. Carbon builds up on the pistons and the combustion chambers and raises the compression. That is why you're mechanic said go to 93 octane gas. No way a 300 should need it and it is a might more expensive as you know, Try Seafoam. Take the truck outside, get it warmed up, take off the air filter and trickle it down the carb throat. You'll have to work the throttle by hand to keep it running. Run about half the can through it this way then let the engine load up and stall. Let it sit for 15-20 min. then restart and run it. It'll smoke a lot when your pouring the Seafoam through and still smoke a while after mabe for 20 min or so but this is normal. You may have to do this in a few months again as the carbon build up starts over again. Check the ignition timing also.

Take a piece of rubber hose and place it on the timing cover and see if you have the noise in that area. If it has steel gears on the timing gears, that a missing tooth or two will make a racked as certain rpm's. I know, I had one do that for quite a while before it stripped enough to quit.

Like others have said....the 300 is noisy by nature, but one of the best wngines for the money ever built.

Using higher octane fuel is a total waste on the 300. It thrives on about the worst fuel you can pour into a tank.

Your are right regarding knocking..ford specs it set so it barely knocks when accelerating under a load.

Thanks

Thanks for all the advice! I'll try some of the things when the weather gets alittle warmer. If I have any other questions I'll be back!!!
Thanks again, Arnie

Does anyone know where to get the tools required to remove the timing gears on a 1994 Ford 4.9L engine? The garbage fiber gear Ford uses finally went.

Thank you

Good Luck! I tried a gear puller and it just cracked the plastic. I fear you may end up having to pull the cam and press it off, unless someone else here knows a better way. It was no sweat for me, 'cause I already had the engine out for overhaul. You might be ableto carefully drill the metal hub in the center and crack it to release thepressure, but you'd be in dangerof getting metal filings into the engine. So pulling the cam seens the best bet to me.

I got in touch with a Ford mechanic, I offered him $25.00 to stop my my house and pull it off for me, he accepted. I also have a brand new engine, that needs to be assembled, that also has one of the fiber gears. For this engine, I'm going to take the camshaft to the machine shop, have the junk gear removed and have a metal one pressed on. Ford, has ****ed me off so much with a number of the stupid ideas they came up with to the point I don't think I want any more Ford's. I have an 85 Ranger with timing gears, metal, and the gears are bolted on, never had a problem. What was the reason why Ford decided to do this with the gears now, other than to make money. was just plian stupid!

Years ago I worked in the garage at a bakery. We had about 25 bread trucks with 240 and 300 engines. Engine noise usually was caused by one of two things, cam gears or a broken crank. Crank will break at a angle and the only thing you will hear is a dull "clunk" when you let off the throttle. Saw 2 or 3 of these in the 5 years I worked there. Most often it is the cam gears. 240 and 300 have different gears but they will interchange if you use the crank/cam gear as a pair. The problem is they don't get enough oil. Look on the outside of the gear cover, there is a boss there where the timing marks are. Drill a hole there and tap it for 1/8 pipe threads. install a pipe fitting and run a line to the pressure gauge outlet. No more timing gear problems. Doug

I may be wrong, but I think that they are more expensive to manufacture. Ford isn't the only one to do this, though. GM, Chrysler, they all had some type of nylon coated or fiber gear for the camshaft timing components. It allegedly makes the engine quieter. I have a 1984 Oldsmobile 98. This thing is super quiet (right now). It's one of the many that I have changed the nylon fiber carp out of and replaced with all metal gears, and I can't tell a difference in quietness. I fail to see how it would affect the 300 any differently, other than it's a beast compared to the other engines.
