Has anyone used Seafoam on their 5.0?

[vristang]

The only prob is that we only put it through the gas and Oil. You are supposed to put it through you vaccuum tube too. The stuff works just ba carefull cause it has created holes if you have em..

I don't understand,
It created holes if you have them?
Can you elaborate?

As far as using seafoam in the oil, just take a second to think that through.
You are adding a solvent to the oil which has a viscosity pretty similar to that of water. It will mix with the oil and reduce the viscosity of the oil.
In my mind this is the same as dumpin coolant into the crankcase. Bad things will happen.
It is possible I missed something? If so, someone please explain it to me.

If you are worried about sludge in the engine then running a qt of aod fluid will do a decent job of cleaning the sludge out.
Keep in mind that you add 1 qt of trans fluid to a fresh oil change. Drive the car LIGHTLY until up to full temp (oil temp not coolant temp). Then drain the oil & replace filter. Drive the car a little more, and drain the oil and replace the filter again.
You don't want to have trans fluid in the oil when you start running the car hard, so it is worth the extra flush of the system.

Anyway, that is what I have done a couple times. Mostly when getting a used motor and deciding to run it 'as is'

If you change your oil fairly often you should not have any sludge issues. The oils and fuels we are running today are very good.

I would not put it in the crankcase or the gas tank, only through the BB vacuum. I had great results with my cobra when doing it through the PVC line and I got good results with th5.0 also.

gcwh02, this is exactly what happened to me, put it in and the next day I was getting horrible blow-by, glad im not the only one.

If you keep it in the oil after addidng it...your using it wrong. I do believe the instructions say to not use for extended use in the oil....it's only for temporary cleansing.

I myself have however have never used it in the oil or fuel...so I can't speak from experience.

Yes if you read the can and read other forums about it, you put a third in the gass, a third in the crank and a third in the vacuum. So this is all supposed to be done just before and oil change. Yes it does break down the viscosity but again thats why you use it just b4 an oil change.

As far as the holes i talked about, if you engine is older over time oil will fill holes in your crank case and gum them up so they dont leak. Well if a solvent is added it will clean these holes out and you will have a leak. This is why you should be careful. I am speeking from experience when i say this stuff is amazing when used in this 3 part way.

can someone explain blow by to me real quick. is it just a vac. leak?

this nasty smoke that comes out is out of the exhaust isnt it?

I see what you're saying.
I guess my point is... Why would you use a solvent to clean out the crankcase, when the detergents in trans fluid will do the job. At least trans fluid is still considered a lubricant.
Just my opinion though.

Yes. I have video of the smoke show somewhere. It works good. Doesn't destroy o2 sensors unless you do it wrong. I used it on a high mileage engine, and it did not cause leaks or problems afterwards.

True it'll clean all that build up but if you're like me and haven't had a rebuild EVER! Then you can start to lose oil pressure cause you don't have that oil built up acting as a sealant. I lose more oil now than I did before I used it.

 

[PoopDawg]

I used it on my '90. Before putting 3/4 through the brake boost vac line, and 1/4 in the tank, I was gettin 180 miles to the tank in the city. After I am getting anywhere from 240-260 in the city per tank. And when I DO drive my car, it's not just cruising.. I have fun. I KNOW this stuff works. You can't get a 60-80 miles per tank difference through a placebo effect.

Ive never had a rebuild and i have 230,000km's on my engine. Burns MAYBE 1 quart every 5000 kms. I used seafoam and it did improve my gas milage as well as improved throttle response. It works and does what it is intended to do. Quit doubting it and just use it.

It doesnt create any problems that werent already there, it simply brings them to your attention so you can fix them before they become even bigger problems.

I like it for detecting exhaust system leaks.

I was using it on my 2.3 TurboStang and found several leaks that added to my turbo woes.

Tried it on my Thunderbird 5.0 and found no results.

 

[ramz28]

ok i've been reading this post and it seems like this product it realy good but im stll a little worried about doing this, i know my oil pan drain plug is messed up, and i know the driver side valve cover is blown, and im not sure of any other leaks except the the crappy ass welded o2 sensor holes, if i run this and i have any more major holes i might have to put my stang to rest a little earlier then i expected. should i run this or not take the chance?

 

[oldschool88vert]

i've used it with good results. it blew a ton of smoke and afterwards it picked up responsiveness. nothing dramatic, just smoother. i only went through the brake booster vac line tho since i just got an oil change. cool stuff but i guess only cause i had positive results.

 

[JIffy94]

I used it on my 84 4000, didnt really notice a whole lot, cause its slow as hell. but it def gave me a little bit better gas mileage. not anything to write home about, but hey, every little bit helps. Def gave off a great smoke show, that was probably the best part about it, I think. It was a riot. I hadnt even planned on using it, just saw the can at checkers one day and heard good stuff about it on here, so i gave it a shot. Look at it this way......even IF it doesnt do anything for your car, its still a $5 smoke show that you dont waste a single bit of rubber contributing to....not that buring out is a waste...but ya know...

so where can i get some?

Yeah another quick Sea Foam question...merged with previous thread

Ok my car has 160,000 of hard miles on it, should i use sea foam? I mean it really hasnt been babied any in its lifetime, just wondering if its a good idea to use it?

couldn't hurt...
