Ever since the seafoam my engine started making these sounds. Sounds like some vibrating, and usually can hear it between idle and 2k rpms. I recently had an oil change after the seafoam, but I notice the sound even more now. Any ideas on what this can be?

dam ur **** sounds really ****ed up, i dont know a lot about cars, sorry

 

Then why post?

 

Wow, I have a vibration due to not surfacing my new flywheel when I installed it with my new clutch it occurs during those RPMs that you are getting that sound/vibration. it's not something spinning in contact with something?

 

I have no idea. That is possible, since I haven't touched the clutch/flywheel since I bought the car (only been 3k miles) Here's another detail: The video you see there is when I put MORE seafoam in through the brake booster hose, about 1/2 can. Before the sound was much less noticable, but when I put more seafoam after a few weeks the sound got worse. That's the video you see.

 

hmm, I once put half a can of seafoam in mine, and I couln't see 15 feet from me there was so much smoke. But no funny sounds like you have... Also afterwards my engine dieseled for about 5 seconds!! I had to crank my volume WAY up to hear it, does it sound like small pebbles in a tin can in person? cause at the back of the intake manifold on mine I have a slight sound like that just before my idle acts up. It sounds like your idle is stable. Was the car at operating temp when the video was shot?

 

thats why i dont really like using seafoam directly like that... i dont really see any difference in performance either

 

I notice a little bit the first time, but nothing in the past two. I did the third in oil third injected brake booster and third in the gas tank most times. That noise is scarry!

 

Seafoam is useless...

 

It's really starting to bug me. I don't know if my engine is going to fall apart because of that noise, since it can gradually get worse. Since it's probably internal, maybe some sort of cleaner/lubricant should do the trick? Something better than seafoam? What I don't understand is what could've the seafoam done to the engine to make such a noise?
