Hey all,

I got the exhaust on the 84 GMC builder pickup today and got to take it for a test drive. In normal fashion for me, something is hosed up.

The truck is a short wide with 3 spd standard trans and a new 350 my brother and I just finished building. I got the cam broken in and everything was going well. The first time we got in the throttle hard today something let go. We drove it home and everythings seems fine except a nasty grinding/knocking noise coming from bell housing area. It almost sounds like a bolt backed out of the pressure plate and is attacking the bell housing.

Anyone want to wager a bet on what the problem is? I am so tired of things breaking.

Throw out bearing is brand new. I thought a about the starter having an issue, but the engine has run for ~20 minutes with no issues. As soon as it started to rev under load the problem showed up.

Mine had no issues to start as well, after the bendix gets worked a few times it acted up...

New starter isn't it?

The noise is the same with the clutch in or out, in gear or out. The starter is not new. It was on the 6 banger that I took out of the truck. It seems to work beautifully.....

I am not saying it is not the starter. I have never had one hang in on the flywheel, but I have heard it can happen. It does not make any bad noises while cranking that I can tell. I have not messed with it too much. I will probably pull the dust cover tomorrow and take a look.

Had a nasty sound once on my 75 Chevell Landau.It was an automatic and the trans to engine block bolts had backed out enough and put the flywheel and converter in a bad bind.I know you have a manual but there is another possible place to look after the starter.

I'm leaning on the Rcastle side of things. My buddy had a late '80's s-10 Blazer that sounded like that too. The torque converter bolts had worked loose. Almost sounded like a rod knock or a rear of the engine main bearing. Is it possible that the release fork is wore on the ballstud? My truck made some weird noises when that happened as well. Good luck.

Is the dust cover rubbing the flywheel? Take it of and try it.

Chris,


With the bad luck you've had lately, I hope it's just a bolt backed out.
Me too. I am hoping I just missed a bolt when torquing or something. If something is trashed I will not be surprised. I think someone is sending me a message about my mechanicing skills or something.

problem solved

Well, I took the dust cover off today and found the problem. A small tab on the dust cover apparently caught on the flywheel and pulled it in so it rubbed. Glad it was easy.

I love it when a plan comes together.


more of the same,.....
the dodge truck i just bought, started making a noise going down the road, only when moving, not at a stop, couldn't find anything with the wheel that it sounded like it was coming from...... started to get worried..... crawled underneath, there was an old exhaust clamp loose on the pipe, every now and then it would make contact with the front drive shaft. a minute with mr angle grinder, and problem solved. I love an easy fix.
