Hello Chris, do not worry about differences in engine sound whatsoever. The block is a sturdy, reliable 350 ci Detroit Iron that, when taken care of, runs and runs.... It is always wise to add cleaning fluids to the gasoline to clean the engine from inside. Love your videos.
Isn't that what they call an "Italian tune up?" People would bring their expensive sports cars to a shop complaining of rough engine issues or such and the mechanic would just take the car out for a hard run somewhere and bam, back to running well. Probably a good idea for anyone who owns a C4 to get it going hard once in a while, where it permits, and not just slowly weekend drive it around town.

As far as I remember that actually HAS to be done when using seafoam. I dont get it why he used it when the car was not able to drive on its own... no wonder it did not work as good as it could have!

Chris, I used sea foam in my Wrangler and it did such a good job breaking up carbon the first time it actually fouled one of my plugs. So it’s good you’re going to change them anyway. Many folks run an old set of plugs for the sea foam process due to this.
I think the engine noise is coming from the accessory drive. My 92 made the same noise. I sprayed some belt dressing on the belt, pulleys, idler and tensioner. If that doesn't make a difference then a bearing is often the source of the sound. Holding a long screwdriver on the alternator etc and putting your ear on the handle will help identify the noise.
I had plenty of run issues with my 88, car would stall 2 or 3 times every day. I treated the fuel with seafoam. 3 oz per gallon. No more stalling for a year now.
Oh ya I use that stuff all the time 2 times a year in my vet , clean the PVC and catch a can out , good stuff it do works Thanks Chris Nice new shirt too 😊
Chris, love the show bro and good luck with the C4. I agree with Seafoam in the throttle body and crank case is awesome but give Berrymans a try for the gas tank. It's so much better at breaking down deposits especially over long storage.Merry Christmas from Texas

Hello Chris, nice video I swear by seafood myself, but my C4 has been sitting for better part of 3mos give or take and it had a dead battery plus completely empty on fuel, I just bought a new battery and put 10gal of fuel and it won't idle, I can get it to start briefly with starting fluid but when I go to give it a little gas it dies out and then won't start back up, what do you think it is?
A long time mechanic told me that SeaFoam was developed for 2 stroke engines and does little to help our C4 cars. He suggested Techron, and I’m telling you it made a huge difference in mine. Whenever I hear the engine starting to miss a little, I add a bottle.
"Cleans & lubricates critical upper engine areas where fuel cleaners can’t reach Cleans intake valves & chamber deposits Safe in all types of 2 & 4 stroke gasoline engines Apply through gas fuel-injection throttle body or carburetor throat Important for modern Gasoline Direct Injection (GDI) engines Lubricates throttle plates, bushings & upper cylinders Use to fog & protect intake & cylinder areas during storage"
and... of course then it works. had great success quieting down my mk2 golf and making actually 5 hp more on the dyno the same day same conditions. Feels more lively especially down low and consumes less fuel. Helped a buddy with his MR2 to do it and he also was very happy. Just watch the video of project farm on it. He is, to me, the most trustworthy source when it comes to testing stuff like that on youtube, not your mechanic all those years ago. @@monroebass2
Chris, great job with the videos! I just bought an 86 convertible for a project car. It starts and runs, but stalls and doesn’t want to stay running. I bought some sea foam but haven’t put it in the tank yet. I also bought some for the oil and throttle body cleaning. I have no idea how old the fuel in the tank is or how much water may be in it. Do you recommend starting with the sea foam? My thoughts are leaning towards draining the fuel tank and filling it fresh before even adding the sea foam. That’s obviously a whole lot more work though. Any suggestions?
I'd recommend draining the fuel from the tank. The way I did it on my 90 Corvette was disconnecting the fuel line from the fuel filter (Replace the fuel filter while your at it). It won't drain all of it unless you could manage to run the fuel pump while the fuel line is disconnected. You could also try removing the fuel pump (should not take more than 15-20 minutes) and clean up the tank. IMPORTANT: Check the gasket of the Gas Cap. If it seems old and dry, it probably allowed water into the gas tank. Replace it as soon as possible. (I know this from personal experience, it can lead to rusty fuel pump assembly, which leads to clogged fuel injectors.)
Did you get any clouds of smoke from the seafoam? . Project farm has a nice cloud going. (I used it twice on my turbo Subaru and no smoke. I was kinda disappointed about the lack of smoke . But my gas mileage when up after the treatment)
We used a product from BG at the Ford dealer. Pretty much the same method, but We would drive the car after the 15 min. When the engine got up to temp, STEP ON IT! Burn out the cleaner, and makes a big smoke show!
Maybe you could run one of those mechanics cameras down in through the spark plug holes when you change the plugs that might be interesting. Although having a before-and-after would have been really cool. Just a thought
I would do an oil flush / then change the oil using maybe a semi-synthic oil... because of the age of the car... I would also replace the oil filter with a high quality oil... run it for a couple 100 miles... and then change it again.. Keep the Sea Foam topped off!!! Use Chevron Techtron two cans!!! Changes the transmission and rear axel..... flush the brakes!!!
When you change your transmission filter, make sure to get the GM filter. They do have it at Rock Auto, it's the more expensive AC Delco filter. As that version is made in the USA. If you get the cheaper AC Delco filter or some other filter, then it's probably made in China.
This is one thing that I'll have to disagree with you on. I've tried Seafoam 3 times on 3 separate cars and each time ended up having to replace the injectors.
Did you replace the fuel filter first? Most likely the Sea Foam is doing its job and contaminants are being dislodged in the tank and going through the system. This is why I did the Sea Foam first before any other maintenance.
Without a before/after video of the valves & combustion chambers there is no way to tell this stuff cleans anything. The fact that it smokes out of the exhaust doesn’t mean it’s cleaning anything, it just means it’s burning something else besides gasoline. With good maintenance you don’t need any additives.

A nice 20 minute drive on the highway and an oil change will clear everything out. Don't forget to replace the PCV valve. Great job Chris!

Hi Chris, thanks for your videos, they are really useful. I have a '01 C5 Corvette in Russia.
Great information Chris, thanks. Hope you and your family has a Merry Christmas.
Great video and I love the shirt! Definitely the coolest design I’ve seen for the C4
Great video Chris and very informative....I'm now a believer in Seafoam.
Dont skip the last step tho!

When i reverse after a cold start and i let the car warm up i hear like a squealing noise, could it be the belt?
@@alexl9334 Its a small child screaming that you ran over them......
yes. @@alexl9334
I did a similar oil treatment on a 1977 pontiac, it somehow screwed the lifters became so noisy i had to change all the lifters
The car DEFINITELY has some rumble now. Not sure why, but I did notice that new bass tone. Looking forward to the follow-up.
I had plenty of run issues with my 88, car would stall 2 or 3 times every day. I treated the fuel with seafoam. 3 oz per gallon. No more stalling for a year now.
Is there supposed to be air pressure in the fuel tank when I take my cap off pressure blows out
Oh ya I use that stuff all the time 2 times a year in my vet , clean the PVC and catch a can out , good stuff it do works Thanks Chris
Nice new shirt too 😊
I can’t wait to have a l98 c4 of my own
Hope u are close to getting one. Im after a 1995 or 96.
I recognize that noise. I believe it's the smog pump.
Hello,
Can you chose one of the methods or do you have to do all 3?
Seafoam definitely works as advertised but kerosene does the same thing. Many think seafoam is just kerosene.
What size tires or you riding on

Then your mechanic was very wrong.

what a coincidence Chris I've seen some of the testing he's done as well, pretty revealing by the way the t-shirts came out awesome!
? Are you changing the filter and oil like NOW! And see how dirty or how much dirt you get out!
Yep
@@mycorvettelife do a update on the crap content in the oil
I've been conflicted about putting sea foam in my 88 vette I've used it on my atv's but I read a lot of mixed reviews
How do you like that lift your using I’ve been looking at them
Been using it for 2 years now almost daily. It’s great.
Hey can I just order a XL tee with a large MY CORVETTE LIFE logo on the back??
How long do you leave the sea foam in the oil?
I would suggest no more than 300 miles.
Great video I have a 86 that iam going to seafoam it this weekend.
you should have shown us the exhaust smoke after wort. so we could see .
....I did....
Is this the same product as Marvel Mystery Oil?

My engine oil must be pretty clean because no white smoke which I'm assuming is burnt carbon?
SeaFoam is oil based, so if you are spraying it into the combustion chamber the car will smoke.

I’ve also heard of people having A lot of problems using sea foam. Some things are better just left alone.
Where’s the “spirited drive”? Lol
seems alot noisier after warming up and about the same after the sea foam treatment.
BG 44 Platinum in my opinion is far superior to Seafoam

The fact that it smokes out of the exhaust doesn’t mean it’s cleaning anything, it just means it’s burning something else besides gasoline. With good maintenance you don’t need any additives.
I can find a dozen other videos that show those things with results.
I've seen videos where guys do a scope of the cylinders before and after. It absolutely works.
But if you buy a used car with miles you have no clue the maintenance that was done beforehand.
It doesn’t tighten your lifters Automatically
SEAFOAM IS MADE FOR BOAT ENGINES AND DOES NOT WORK VERY WELL WITH ANY OTHER VEHICLES!!!!!
This is false. An engine is an engine.
It's an engine, the same as a boat. If it's such a travesty then how come they sell it and not have a huge class action lawsuits?
