There is aticking sound coming from the engine. Sound like it's one the driver side of the engine. When it warms up, the ticking gets quiet. It doesn't go away completely. Anyone know what the problem could be? Thanks!
And I think I might have a knock?!?! Not sure if I'm just paranoid or if I'm really hearing a knock!

Sounds like a loose exhaust manifold.

I agree with 442harv, if you can feel around the exhaust manifold quickly after start up from cold.
The knock could be a bad motor mount or trans mount.
I would check the oil, do an oil change and see if its clean.

I merged your threads and fixed your link. Its better to keep all the info in one place instead of opening multiple threads.

Copper Nine Eight

Thanks! Sorry about the multiple threads

76olds

Man, I hate to say this but it sounds almost like a connecting rod. Was the hood up or down in the running clip?

Copper Nine Eight

It was from the bottom of the car. You can hear it better from the bottom of the car or if you stand back.

I clicked on you tube link and ended up with china! I think

Copper Nine Eight

Lol wth. Well that ain't right

Rustbucket2

without hearing it, the first thing I would check is flywheel, I had one that had come lose and sounded like a knock in bottom of motor.

oldcutlass

That is definitely a noise. However can't really make out exactly what it is from the video. What happens when you increase the rpm's, does it get louder?

Copper Nine Eight

When I increase rpm's, I stop hearing it but I'm pretty sure it's because of the fan and belts drown out the noise. And when I decelerate the sounds can be heard again.

The speed of the knocking sound increases when I accelerate and decreases when I decelerate. And when I put it in park, at idle it speeds up.

What weight and brand oil are you running? What is your oil pressure?

Copper Nine Eight

10w-30. Oil pressure, I have no idea.
Oh and the brand is pennzoil. IF YOU RECOMMEND A DIFFERENT WEIGHT AND BRAND PLEEEEEAAAAAASE TELL ME. I stood in auto zone looking a oil for 30 minutes trying to pick smh. And that's what I ended up with.

Copper Nine Eight

That would make some since. The transmission was rebuilt 2 months ago and I swear I don't remember this knocking BEFORE that. I'm still under warranty so I think I will take it up there Monday and see if they will tighten it down. And hope that fixes the knock.

oldcutlass

I'd pickup a cheap mechanical oil pressure gauge and hook it up and see what it is cold and hot.

Copper Nine Eight

Will do sir!

If you can hear the knock as the key is turned off but the engine has not stopped all movement yet, it is likely loose torque converter bolts.

Copper Nine Eight

Ahhhhh yes I can! I will go have the people that rebuilt my trans to look. Thanks man! And everyone. I LOVE THIS FORUM!. Hopefully that's my problem

Rustbucket2

well, was it the bolts?

Copper Nine Eight

Literally at the shop right now finding out! Lol I praying it is. Will let you know when I find out!! Pray for me lol

Copper Nine Eight

They said it wasn't. Said it's my engine :/ horrible engine knock!

76olds

Ahh that sucks, I thought it sounded like a rod. Are you still trying to diagnose the problem ?

Randrup

So...?? Did you find the problem? :-)

Ive got a 307 in my '83 custom cruiser and its got a similar knock that acts the same but yours sounds much meatier

Check the transmission yourself, or have someone else do it.
Im a plumber, people think plumbers rip people off....how about transmission places, im better at transmissions than 4 trans. shops here.

Also, an engine knock will get louder with time, how many miles since the trans.

Copper Nine Eight

A little over 1000

I replace my egr valve and the knock isn't as loud. My dad said I should go with a straight 30w oil.

See if your egr valve is bad. You can check by removing the egr valve and compressing it by hand so that you hear air and cover the small hole that's on the part the hose goes over and if the valve doesn't stay compressed then it's most likely bad.
That's if you didn't know that already!
The new egr valve helped my knock!

Northern Custom Cruiser

Are you sure you arnt referring to the choke pulloff? On the passenger side of your carb?

Copper Nine Eight

I'm sure. It's on the driver side right by the valve cover. I'm serious haha! It helped my knock! Luck maybe? Who knows ha

Northern Custom Cruiser

I was informed to whack it with a hammer... But i guess your method works as well xD
