Yet another potential chore - Timing Gears
Since I've been driving the truck more, I've notice a rattle or knocking sound coming from the front of the engine. It's intermittent and doesn't matter if the engine is warm or cold. It happens at speed and at idle. When it happens, you can feel it in the distributor.
I'm thinking worn timing gears..
If I'm on track; any suggestions on the best way to replace them? I haven't done this on the I6 before. I know in my 292 Y Block to deal with such a thing I'd need to pull the cam. On that engine, I can pull the cam without having to remove or lift the engine.
On the I6, can I just pull the radiator grill, to make clearance or do I need to lift or pull the engine?
Any thoughts or advice on this potential project would be appreciated.

If I don't need to pull the cam, that makes it much easier. Just get access and pull the gears (after make sure timing marks are aligned first I assume).
I'm wondering about timing. When I did the 302 (30 years ago..) I recall their being an option to install with advanced cam timing or normal. Does the I6 have that option?
Research Research..
On another note, my exhaust trip to Meineke was bust. They couldn't make or get the front pipe and referred me to a custom shop. I'll be giving them a call tomorrow.

Years ago I played with cam timing on a Chevy 305 in a boat. In spite of everything I read saying it would make a huge difference it really didn't. With a stock cam I'd probably go back stock on the timing. But, the 300 six forum is the place to ask about that.

KSC - Do some searching of the archives in the I6 forum or maybe ask out there...

I changed the fiber timing gears on an I6 in a 86 F250 years ago. Didn't have to lift the engine or anything.
The new gears were steel, and always whined terribly after that. Darn thing sounded like it had a 6/71 blower on it!

You want steel for durability and longevity. My 73 had the plastic coated factory gears. When the plastic fell off, the engine would never stay in time. Always overheated. I put steel timing gears in when I rebuilt it. Problem solved.
Ironically, I have only overhauled 335 series engines.....

A Buddy of mine yrs ago was having this same problem turned out the plate that holds the cam in had broken bolts .replaced the 2 bolts no more problem. He was lucky no other damaged had occurred.

To change the cam gear you must pull cam.Pulling fiber camgear with cam in truck can be done but chances are you will break the outside of the gear off and then have to pull the cam I have done a lot of these and found if it has fiber cam gear just pull the cam .Some say the steel cam gear will make more noise but I personally say replace the fiber gear with a steel one
