I'm new to this forum and american cars/engines in general, I hope you guys can help me

I recently bought a 87' Caprice with a completely stock 305 engine (non TBI, 146k miles on it), unfortunately it didn't even make the way home the day I picked it up...

I drove it for about two hours without any real problems, the engine hesitated a little under acceleration from time to time, but I figured it was due to not being driven for a few month during winter...

As I drove up the freeway from a fuel-stop, I put it back in overdrive and suddenly hear a silent (luckily the radio didn't work ) ticking, which seemed to be coming from the tunnel right under the dash...so my initial thought was that the transmission/ TC was getting into trouble.

I took the next exit and rolled down the window as I sneaked the car to the next possible parking spot and heard that the noise was actually really loud outside the car and the idle was way too high in Park and almost stalls when putting it back into Drive :...so I shut it off and called a tow truck.


The next day, something odd happened: I wanted to drive to car a few meters into my garage and the sound was completely gone, so I let it idle for a few minutes and the sound slowly returned, but very infrequent in neutral and completely gone in gear

Later that day, I went to fire it up again and the noise was there again, so I took quick videos:

When you stand infront of the car, the noise is actually more present on the passanger side...

shortly after that, the Idle began to rise again, I guess the timing and carb setup are completely off...

Haven't run the engine since then, It ran about 5 to 10 minutes total with this noise, most of it idling...

As I wrote before, I have no experience with this engines/cars, so I hope someone can point me in the right direction

And please forgive me if some of my grammar is wrong, I'm a german dude doing what I can :drool:


Thank you very much
