TWG Episode 3: SHE RUNS! SOUNDS LIKE HELL BUT SHE RUNS!

[@Carl_Jr]

As many have suggested, pull the serpentine belt off so you can actually hear just the engine run. My bet is probably 90% of the sound you're hearing is the AC compressor. After you get that done I would go through the typical stages of testing the engine from top to bottom. Do a compression test. Pull the upper plenum of the intake manifold off. Pull the valve covers off and check the rockers. There are a lot of things that you can do to test the engine to see if it's even necessary to pull it out of the car. Don't just jump the gun and assume you're going to have to pull the motor. Learn as much as you can about diagnosing an engine and you could save yourself a lot of money in the long run.

[@Rob-lv7wo]

Between the clicking sounds and chirping sound, I would take the belt off then run it again. Just to eliminate any noises from the belt accessories.

[@davemilligan1171]

Agreed.

Sounds like lifter, pull the heads and check them before you yank the engine. Loving the videos!! Bringing back memories of my old camaros!

[@korbendallas4232]

I hear you. I sold my last Camaro when our first child was born, I still miss it.

[@aubreyi9986]

the one i miss the most is my 25th anniversary Camaro. White on White with that good ole' red interior. i wish i had that one back.

Thank you! So glad you’re enjoying it. We’re having fun making it!

[@keegie7185]

At least *some* of that noise is coming from one or more of the pulleys. Costs $0 and 5 minutes of time to pull the belt off the tensioner for 30 seconds and see if there's a difference. I love ruling things out by process of elimination.

[@Mltemple8333]

Declan the optimist! “Well the backup lights work”…. Gotta. Love it.

[@ThrowingWrenchesGarage]

[@korbendallas4232]

I still have a lot of love for this generation Camaro, especially the IROC version.

[@resurrectionmotors2421]

Listening to it over the phone, it's difficult to tell. But I would take the belt off of the accessory drive pulleys. And see how much of the sound still persist. God bless

[@ThrowingWrenchesGarage]

It's definitely hard to hear over a device but, in person, it's pretty undeniable. Bottom end noise that gets worse with RPM

[@TomWood60]

Enjoy the videos. Do what you want with the car and ignore some of the internet experts, someone really commented on a Fram oil filter? Scott at Vehcor has a whole meme about guys like that. Do not apologize for your welding or any lack of experience. Just do it with your son and have fun.

[@MikeyMack303]

Thank you for taking us along. I think most of us know how much exhaust system work really sucks! Good job!

[@Black91RSCamaro]

I have a 1991 Camaro RS. I love these cars. I bought mine brand new July of 1991. For your battery terminal issue, I used a coarse nut and bolt on each one. I use the nut as a lock nut to ensure a good connection plus the head of the bolt makes a good post for charging or jumping off the battery. Just my 2 cents. I look forward to seeing more progress on the Third Gen!

[@goodvibes5487]

I'm digging the content so far, although....seeing your Chevelle sitting there with no cover on it while you grind and work around it is killing me! Lol.

[@thejourneymen7722]

As many others have said, I would start with the serpentine belt because it doesn’t sound internal sounds more like an exhaust leak to me maybe the smog system if there is one or a blown exhaust gasket, I would also check the spark plugs One of them may be loose.

[@royrexhausen8258]

Check your distributor and timing. Remove the serpentine belt to rule out accessories.

[@dansanmiguel5750]

I have a 90 iroc L98 g92 car.i had to put in a mini starter cause of heat soak.the mini starter did the trick, and now the car starts after a long drive no more waiting for it to cool down .Keep up the good work .

[@russmurphy7062]

I can gaurantee, thats a rod knock. Ive built so many small blocks, til I can recognize that sound. If youre lucky, itll have a spun main bearing. But this isnt gonna be cheap, by any means. Crank kit,gaskets, bearings, oil pump, timing set.

[@russmurphy7062]

Make sure you change the lifters too. I heard one tapping bad. The ticking you heard is probably the rocker arm is loose from a collapsed lifter. Check all the rods for being straight.

[@richardernst8857]

It sounds like an old antique car in the early 1900’s hundreds

Yeah she sounds like she's hammering id definitely pull it out and do a simple rebuild on her.. Nice welding job there was nothing wrong with that and i love your sons name its unique and awesomene!!! I do have hubdreds of small third gen parts especially clips retainers bolts and interior parts ill donate anything you need for your son if i have it.. It took me 5 years to restore my third gen camaro and build the nitrious engine i wanted so i have tons of parts and if he needs them just let me know what you need and if i have it ill mail it to you free of charge

[@ThrowingWrenchesGarage]

Thanks! Thaf’s very generous of you to offer! When we start putting things together instead of taking them apart we might need you!

[@RyanBadger-o9n]

Been loving the Channel keep going

[@bosmerfromcanada3878]

The noise definitely sounds like worn or spun bearings, camshaft is probably worn-out/rounded, and the valve lifters sounded like they were clicking or ticking. These are usually the top three reason for shavings in the oil in Third Gen. Camaro 305 small block. The crankshaft is probably starved for oil or has a plugged channel which why former owner overfilled it. On the plus side, it is a great opportunity for Declan to learn...a little at a time and Chevrolet is relatively straight forward, easy, affordable to work on. Unlike European cars, you'll never lack parts or suppliers. Subscribed.

[@greatbull67]

Loving this car and project.

[@EthanRempel-mk8xr]

Talking from experience, you should definitely pull off the front bumper when pulling the engine. It gives you almost a foot of room, which you’ll definitely need if you’re using a cherry picker. Good luck on the rebuild guys!

[@ThrowingWrenchesGarage]

Solid tip! Thanks

[@EthanRempel-mk8xr]

@@ThrowingWrenchesGarage My pleasure! I love watching you two work together, and I love seeing other young guys getting into older cars!

[@retrobear9367]

Looks like she's got some fairly decent speakers in the car. When you get to the audio system. I gutted the Bose crap in my 03 Corvette. I replaced the speakers with polypropylene cone Kenwoods. I would highly recommend them in the Camaro. They sound good and can take a beating. With the engine. At least you're pulling it from a Camaro and not say... a Mercedes. Ez pz

[@jeffcorum8312]

Just come across the video...if it had more oil after Drainage the oil pump might have lost prime(drained back in pan) the lifters have probably lost prime(tick-tick-tick)...maybe re-prime oil pump...👍

[@ronaldwarren5220]

Dump a can of Marvel Mystery Oil into the crankcase. Or a bottle of Berryman's. Kinda sounds like valvetrain to me. Before you pull the engine you should drop the pan and check the crank and rod bearings after adjusting the valves. Good luck!

[@nowherefastgarage]

Great project! I’ve been working on an 84 z28 for a few years now. I hope to be doing something like this with my son when he reaches this age.

[@Kilnor]

I would look into all the easy engine stuff before committing to pulling it out. Could you perhaps on the next video tell us where your experience is, like what you do for work? You say you don't know what you're doing, but it seems like you're doing alright to me!

[@mtrgv]

It sounds like something is making noise as it's rotating. I would remove the serpentine belt and run the engine again. There is a possibility that one of the following; smog pump, p/s pump, a/c compressor, water pump, alternator is locked up or the bearings are bad. The car will start and run on off the battery alone for at least 1/2 hour. The glitter in the oil pan and filter may have come from the factory timing chain hitting the timing chain cover and gouging out metal as its rubbing and rotating> ?

[@kevinfrench8055]

100% spun rod bearing

[@sambarnes9520]

Compression test would be good before pulling it.

[@mattc6872]

Pull it and rebuild it love the videos

[@jeffs4690]

Just friendly advice but if you do pull it mark and label every line, hose, etc. for making the install process smoother. Hopefully you don't have to but almost seems like that's the road it's headed down. Plus think of all that content for new subscribers 😉

[@Zelaznogsiul-63]

I am no expert, but may be a flexible pipe could’ve been used to replace the missing section. Great video.

[@rbest402]

..and you might as well put a kit in the transmission if your pulling the motor. Its not much more work. I put one in my 89 iroc and it was so much more crisp. And I had the 350 version

[@adamdewitt1]

I cant believe you didn't do the patented Derek Bieri fire test when you hooked up the battery ! LOL

If I was a betting man it was an RPM death or a pulley/other, Nice car and worthy of... I hope your Son realizes what he has, buy him another "I'm learning the Driving thing" car and add this one to your collection.

[@mtrgv]

Your welding is good. With welding the more you weld and fabricate and repair stuff the better you get at it. I would use 4 jack stands and get the entire car off the ground as high as possible.

[@silverback8183]

Sounds like everything is knocking! Someone rode that poor car hard!

[@MichaelDean1]

Sounds like timing chain is slapping,may be why it back fired also.Definitely lifter tick also.may have collapsed lifters,the 350s love to do that.🙂

[@timsharpe2419]

Yeah it sounds rough but hey you guys scored you cannot find them like that anymore . It's most likely turned a bearing but I would make sure that the torque converter is tight and the flex plate is not cracked or shattered. To me it does sound like it's got some noise coming from the flexplate. You don't have anything to lose by checking that's for sure. I've seen those flexplates crack where the 6 bolts fasten them to the crankshaft. If you pull the converter bolts out of it and slide it back as far as you can you might be able to see up in there possibly if not I would get one of those camera attachments that go on your phone with a 90° camera on it so you can see what it looks like

[@tigheklory]

Before you pull the whole engine run some detergent oil though the engine with some Rislone and Lucas oil mixed in. You might just have a stuck hydraulic lifter, I had this happen in my Camaro years ago. I ran that thought it and then used Royal Purple and the lifter noise went away.

[@richardernst8857]

I wouldn’t have saved that old exhaust system Noooo way i would have taken it somewhere and had stainless steel tubing with flow master 10’s put on it just behind the rear axle and wake that baby up i have them on my Challenger Hemi and my Z28 and they roar like a beast I like it fast and loud and I would put sound deadening in the interior before you put carpet in it

[@michaelbloom5342]

Hooker makes (or at least they used to) headers that are a direct bolt-in. I had them on our 85, and they were fantastic.

[@daredevil7442AUTOMOTIVE]

Eh, can’t really hear good compared to being there in person but, I would pull the serpentine belt off and have a listen and another problem area with those Z’s is the flex plate. The plate cracks around the bolt holes and sounds like bottom end is demolished? Someone cut that exhaust for a reason?? Hard to believe that 305 is toast? Although, shit happens.

[@michaelsim4338]

Check the lifters, then pull the heads..could be something bent or broken

[@wellingtonroad]

Keep the videos coming.

[@michaelfrederic7343]

Noisy water pump bearing. I don't hear any bottom end noises. Just top end. Lifter/Valvetrain noise, it sounds like. To fast to be bottom end. Try the ol' vacuum hose stethoscope trick. If you yank the motor just save it in plastic wrap and ls swap it!

[@markbonwell209]

Remove the belt and try again just out of curiosity, BUT as soon as I heard this engine run I was immediately thinking it has spun the main bearings and will for sure need a rebuild. I can hear the exhaust and A/C making noise as well but this is very familiar to me. I've owned 2 of these cars and one of them had this same result. My opinion is to get a remanufactured engine and give that one as a core, or find a good donor car with a good engine if funds are an issue. Although a sad situation, your son will definitely learn a lot.

[@andrewforbes146]

IS THAT WATER PUMP OR TIMING CHAINE OUR A LAZY LIFTER OR TWO

My friend welding would've been the last thing on my mind I'd put that piece back in place and taped it close as best as I could and then attended to the engine noise everything should operate off of that engine and then worry about the exhaust won't you find out whether you need to get a short block or not just saying By The Way I'm highly Jealous that's a Gorgeous Iroc z 😎

[@ThrowingWrenchesGarage]

I had a welder but I didn’t have muffler tape. Believe it or not, the welding was the lazy way out! I only repaired it to make it easier to hear the engine noise and to avoid pissing off neighbors. It definitely was not a “repair”

[@07Knightfall]

Chevrolet offered the IROC-Z trim model of the Z/28 from 1985 to 1990, its badge nodding to the International Race of Champions series that sprang from the brain of Roger Penske to become a fixture on ABC's Wide World of Sports. So the "Z" stands for Z-28 so you were correct in your original statement. Don't listen to all the keyboard warriors out there.

[@toddprater14]

The iroc z became a model in 1988 on thru 90…before it WAS a trim on the z28…if you look in the console on the spid sticker on any 85-87’ it will say z28 with the rpo codes…1988 it became the model and the z28 was dropped till it was resurrected in 1991 when Chevy didn’t renew the iroc contract…all 1990 irocs were built from august 89’ till December 31st 1989 and were done…they retooled the plant a bit and the 1991 z28 came out early in April 1990…this is why there are so many 91’s..they were built from 4-90 till July 91’ ..August of 91’ started the. 1992 builds till august of 92’ and the plant in van nuys ca was closed.

@@jeffs4690 at this point I'd wrap the nose and the rocker-panels if I was worried about scuffing them, that bra probably traps more heat too besides scratching the paint

[@jeffs4690]

Agreed they are horrible on the paint. Had a few on my late 1980s TAs back in the day. By the same right if you had front end scratches, paint peeling or worse they could hide the damage. As far as heat that wasn't a problem with having one that I ever recall. The LeBra was the higher end brand to have and had ventilation built in if needed for other models. Wasn't necessary on a TA though. You did get individual headlight covers for the flip up headlights that usually rubbed and came off eventually.

From the oil change last video, you have either a spun bearing on the crank or a cam bearing is wiped out... It now comes down to your budget, to rebuild or replace with a 350, you should be able to find a good motor on marketplace for a decent price... I wouldn't go back with a 305.. Back in the 90's when I had my 3rd gen I swapped the tired 350 tpi with a build 383 stroker from a monte carlo that a guy crash out running the cops... I didn't have any of the build spec's of the internals but I tell that engine had some hp's behind it, the car got stolen and the guy was toying with a detective going down the highway and it turned into a hot pursuit and they caught him with spike strips and he ditched the car tearing the front end up.. Sorry I got caught up in the moment there lol... Anyways good luck with pulling the engine..
