305E in Illinois
Hello-
Anybody have a good guy that knows the 305E V6 engine in Northern Illinois / Southern Wisconsin? I have a crazy knock out of the blue that I can't chase down. She was running beautifully but then started a gradual knocking. Suspect some kind of lifter noise but I am not a mechanic... I do have some valve lash over tolerance which I am going to adjust next time I'm in the garage, but may need a solid valve job or other more technical help. Thanks in advance. Phil 1964 GMC C1000 |

Re: 305E in Illinois
An easy possibility to check is ignition timing. Maybe you will get lucky. Good luck.

Re: 305E in Illinois
Like Jim and George said, your best bet for a mechanic is you and us, neither of which are mechanics haha.
BUT We can talk you through just about anything and these aren't complicated engines. The only thing you might run in to is a parts availability issue. Start with the easy things. 1. Take a video and post it up on youtube or rumble or some random site. 2. Buy a 10.00 timing light and check your timing. 3. Check your oil level because low oil will definitely give you a knock/tick.

Re: 305E in Illinois
Did you pull or replace the spark plugs? Or removed the air cleaner?

Re: 305E in Illinois
Timing is pretty close. When I use a seascape I can here it best in front of the edistributor closer to the carb with scope on top of the valley pan. Plugs are new as is pertonix module, coil, plug wires. I put in a American autowire upgrade kit as well. Trying to upload a video. Also- i recently found some valve lash well over spec so I am adjusting that soon.

Re: 305E in Illinois
Timing is pretty close. When I use a stethoscope I can hear it best in front of the distributor closer to the carb with scope on top of the valley pan. It does not sound down deep to me, but what do I know! Plugs are new, as is pertonix module, coil, plug wires. I put in a American Autowire upgrade kit as well. Trying to upload a video. Also- I recently found some valve lash well over spec so I am adjusting that soon. Oil level and pressure is good too.
It seems to be running quite well other than the knock- no great vibrations or grinding noises anywhere. Appreciate the comments. |

Re: 305E in Illinois
It's probably an exhaust leak....manifold or pipe. I assume you have checked the oil and plugs for color. Assume no backfire at carb or exhaust. Starts and runs good, no major missing/stuttering. No smoke.
Also there is nothing special about our V6 motors as far as finding someone who "knows" them. It's a standard internal combustion carb and points motor. It has tune up, timimg and valve adjustment specs on this forum. Nothing different to troubleshoot than a Chevy V8. Etc. Last edited by AZKen; October 5th, 2024 at 09:02 PM. |
