So today i had a little extra time on my hands and decided to use the bottle of extra SeaFoam i had . So i ran the motor until it was at operating temp , while it was idling i let a vac line suck in 1/3 of the bottle and let it sit for 5 mins like the instructions say . Well while i was craking the motor back up the engine makes a popping noise and stops turning . Well i let it sit for another 10 mins and try again and now my motor sounds like it blew
Oil is now leaking from my exhaust manifold and the car sounds like it spun a bearing .

At idle

 

Thats the Tussin doing its job. Robitussin FTW

seriously though that sounds not good.

 

Did you just stick a hose into the bottle and let it quickly suck up the liquid or did you slowly add it while revving the motor? Did the motor die when you were sucking up the liquid?

 

/\/\/\ thats what i was thinking, your supposed to only do it a little bit at a time. Otherwise you risk hydrolock.

 

Crappy man that blows!!!!!! Sounds exactly like a rod, I thought I spun a bearing yesterday I was sh!ting bricks, took a couple buddys out to show them my progress and coming back into town I thought I heard knocking I was sweating!!!!

 

Let us know what you find out.

 

It was put in slowly by only putting it threw a vac line .

 

That sir is rod knock.....sorry!!!

 

Yup its also spitting out alot of oil , probably bent the rod , cracked a piston and bent a couple valves .


For some reason i think the SeaFoam was bad and it became flammable exploding in the engine .

 

Well, it is a hydrocarbon after all. Just like the petrol you put in the tank. So it is supposed to burn - that's not a problem.

If you only added small amounts, while it was running, then all should be fine. However if enough was added to allow a hydro-lock condition, then it woulda started making noises before you shut it off.

Unless the vac line was filled with liquid after it shut down and then sucked in the tubes worth of liquid when it restarted. Even then I don't think most small vac lines would hold enough volume to lock a cylinder - it would need to be a large and long one (we're talking about vacuum lines here). Chamber clearance volume is in the 50+ cc range and there's four cylinders...

In any case stop running it and get to the tear down. It won't get better by itself.

 

I'm afraid you added the seafoam incorrectly, because what everyone is saying is right. Time to buy a new engine I'm afraid. The cost of rebuilding will be about the cost of a used engine with low miles.

 

Seafoam works fine for me! Use it almost everyother oil change!

 

wow didnt notice this thread was so new..
ya u hydrolocked the motor..
u should be able to get a motor from lkq or other salvage company for about 300$.. shouldnt take but about 6 hours to swap the motor.. (ive done it enough times lol)

 

I believed he did a rebuild of the motor he had.
