I Fixed A Horrible Engine Noise & Dead Cylinder On My LS Police Car! Cheap DIY Fix Anyone Can Do!

After I watched the original Legit PPV series, I had to have one! I searched the auctions for months and finally got a 2014 Caprice with only 68,000 miles. Only paid $6,500. California car no rust. Love that car. I park it on the street in front of my house. No more crime! I can't thank Alex enough for his inspiration!

[@LegitStreetCars]

Wow, great deal! Congrats!

The last LS

[@TireSlayer55]

I had a white Crown Vic ex cop car right after high school and when I first got it I would prank my friends by pulling up to their houses or parties in it… never thought about crime deterrent effect of having a cop car in front of my house as an adult though, now I think I need one again…

Where are my LS guys at? Whatcha got! My current LS collection is my 2001 WS6 Trans Am, 2011 CTS V Wagon, 2012 Chevy Express 3500, and the Caprice.

​@@LegitStreetCars, I have one question, apart from the Mercedes giveaway on your previous video, do you plan to do another giveaway on your next project car??? Perhaps the Black Grand National or the white Corvette???

Yup I second that comment. Awesome to get back to the older style content from time to time.

[@SR-gt350]

Electric cars are hypocritical. Look at the amount of specialty metals and rare earths compared to aluminum and steel in an ice car. Now look at Lithium required and where it's mined and human rights violations. Not to mention the amount of great oil and gas technical jobs lost that were employing Americans and Canadians. It's also in cold weather the ice shines (no pun intended). You get immediate heat as well quick refill. You can wait upto 30 hrs waiting for charge and due to cold weather and keeping battery warm 1/2 the mileage per charge.

[@dakotaruiz3890]

Holy cow, 3 years already?? Time flies, it felt like just last year you were doing the rebuild.. Keep up the amazing content!

[@rustler08]

That adjustable thing is a quarter-wave resonator, sometimes called a Helmholtz resonator. The reason it's adjustable is not to change the exhaust tone as a whole, it's so that you can eliminate drone at a specific frequency where the length dictates the resonance frequency (more specifically, it's based on 1/4 the wavelength of the drone).

Excellent methodology and troubleshooting. Usually hardest of all is the diagnosis,without just randomly throwing in parts into it! Well done mate all the way from Australia 👌🏻

[@lrnasigo1]

Alex is so calm when diagnosing an issue that would make most shade tree mechanics freak out 😂

[@quantumtime6883]

Always great to see you take the time to properly diagnose and repair the issue with your vehicle. SBC is a great engine, also I have had good luck with the Ford 302. I was in Florida and took a Airboat tour and the boat had a supercharged LS engine with straight headers, awesome power and sound, had to wear earplugs. I highly recommend the airboat rides, incredible power and reliability.

[@jacobcashen1301]

Said it many times and ill say it again: your caprice is a legendary car and arguably my favorite on the channel. Glad youre keeping it forever! It was also the car build that led me to your channel. The video of you buying it popped up on my recommended page and the rest is history!

[@guiart4728]

That was an amazing display of ‘spidey sense’ to track down that broken plug! Imagine taking it to a shop and having it returned after a week with no clue!!! Well done!!!

Finally more Caprice content... I'm slowly modifying my "Holden WM Caprice" into a "HSV E3 Grange", so all the Caprice content is really appreciated so i can see what i may want to do to my own Engine at some point!

[@warpspeedracer]

Dang, I miss working on my Trans Am. Engine was so easy to work on. It's always cool to see your thought process in diagnosing the issue. Cutting that injector open was just funny, I got a laugh out of it. Great job in making an unexpected problem into such an entertaining and informative video.

Alex glad you almost at a million subs. You actually work on your cars and finish your projects. I just really enjoy watching an actual master tech work. Thank you.

[@DouglasJobin]

The J pipes are for attenuating drone like Solo said, and it seems the optimal length for the pipe is 30.5". Someone online did some math to figure that out and when I built my own J pipes I used that length. It totally killed the drone on my '14 Caprice, which was impressive due to how ear splitting it was before. Glad to see some more Caprice content! Hopefully you decide to LSA the car around the time I'm doing the same. Would love to see your video on something like that!

Trombone, correct answer! Slide Trombone to be exact, there are valve trombones as well, but rare.

You could also check the resistance in ohms of each spark plug with a multi meter. There could be a vast difference in resistance/ohms between all 8 spark plugs.🤔🤯

Really appreciate you showing us your diagnosis flow, everybody loves a mystery!! Also, maybe reward the LS with a new headliner??

[@mattbuckley5038]

Hey where is Peter these days , not seen him in recent videos

[@kingersgarage]

I also custom welded a Solo J pipe to my exhaust on my LS swapped RX7, it is adjustable to change the frequencies that the waves bounce into and hit the cap, and bounce back to the exhaust stream to cancel out drone. How you tune it is get a sound analyzer on your phone, and you will see one freq really higher in db then the others, then go and look at what length you need to adjust pipe to cancel it out. On my tin can RX7 it BOOMED at like 38hz and that was 25" so I adjust it to that and now zero drone when cruising. My exhaust sounds sooooo good and no drone. Makes a difference in smaller cars, the caprice has mass to help absorb some of those freq. So you are tuning for a certain freq not to change the overall volume. Cool find for $8K!!

[@InHypnoticTrance]

I like how wacking things on cars is sometimes a legit way to make them them work. I used to work as a kid at this place that repaired MGBs. I took one on a parts run / test drive and the car didn’t want to start on my way back. Call the shop and when he told me to tap on the fuel pump (which is obviously external to the tank on the MGB) I was a bit surprised when that actually worked and the car started. Also, I’m a Chevy guy, got the LT2 in my C8. I like that Caprice though.

[@scottc78]

Even if you aren't getting a lot of extra power from E85, it has cooling benefits as well. I almost wonder if you'd get more power after another tuning session with the new injectors, the old ones were looking tired. Really need a ton of flow for that corn juice.

[@idwellinthehillslikegandhi]

[@abdullahhajat3364]

Wheres Peter at ?

[@grumpychocobo]

Had the Solo setup on my Chevy SS. Adjusting the J pipe length won't change the sound really, at least not a noticeable amount in my experience, but it will change what frequencies it best combats. They are basically there to combat resonation so like, if you're cruising down the highway and getting tons of resonation, you can tweak the length of the pipes to try and better target those resonant frequencies and eliminate that drone.

[@grumpychocobo]

You know, one day I'll learn not to pause a video to comment cause half the time, 30 seconds later, what I said becomes pointless. lol

I went to the Australian distributor of Amsoil recently and we chatted about the Holden performance company , HSV who sent customers to him for Amsoil as it was best for their highly tuned motors. He tests the oils for customers at the CAT Diesel Headquarters across the road in their laboratory and amazes them with its quality and performance in diesel motors small and large. The Cummins guys nearby allow Amsoil to be used by owners in their maintenance program due to witnessing the 1 million (mile or kilometre i dont remember....) regular teardown ( as a maintenance schedule) and seeing that the oil stays clean and the motor is like a third of the normal expected wear............This Man had so many stories of great outcomes from AMSOIL! He has a HSV Ute and build and maintains Honda race cars for a local race series in Australia. he is passionate! He got me into using the right Amsoil for my high mileage Volvo V8 and my Volvo T6 turbo engined cars both Signature 5/50 as the T6 is also high mileage and also fluid for the transmissions! So far my XC90 V8 is sounding sweeter and revving so much better , may have a little more power from my butt dyno........Amsoil is the ONE!
