- With Cylinder 1 and 3 reading 30 and 60 respectively, it wasn't looking too good for my turbo m54b30 e46 drift build, but after some feedback from you guys, and some helpful insight on the forums, I decided to give seafoam a try, and not in the traditional sense with a huge plume of smoke.

It actually does the opposite on most occasions because it is the carbon build up in the cylinder that's making the seal compensating the wear on the rings and seals
Thanks for sharing love! I was told about Seafoam as well because I have carbon in my 2003 BMW 325i engine and I was having a hard time accelerating to 40!!!! I put seafoam in the gas tank and it ran better within MINUTES!! I have to go an oil change now so thanks to you I will see how this goes. I maybe able to record it!
Nice! Glad to hear seafoam helped you out.
Did this end up working for you? Going through something similar
Seafoam is good shit man, For years! No matter the car! Whether in the tank, the crank, or intake! Have never seen it applied directly in the cylinder tho! Good shit.
Sea foam is definitely awesome!
Also don’t get mixed up, your compression will be higher if you have oil or seafoam in the cylinder
Totally understand that. It was just enough reason for me to give the green light 👍
🤘🏻🤘🏻🤘🏻
I’m catching up on subs bro. Glad you’re sticking with m54 😤
Hell yea man, keep on grinding! I'm pretty happy with the decision myself.
There are a lot of solvents I've seen recommended for this - I'm about to do it myself, and I think I will go with acetone/ATF in a 1:1 mix.
The problem is one of design - this engine uses only two rings, and they are low tension; I would suggest the O2 Pilot mod for the CCV in addition to this cleaning because the extra vacuum both pulls the oil vapours out of the head and sucks the oil rings against the bores.
I think the big misconception is that the more smoke the cleaner, but actually seafoam is Petrolium based so as it burns it smokes, equivalent to putting oil in your cylinder and then running it, but dope video I just Performed the same thing but I let it sit in each cylinder over night
So u leave SEAFOAM in the effected cylinder overnight, suck it out, do it again then test compression the next day? Is that right?
yes, did you even see video?
Great results in cleaning my n54 with seafoam or marble mystery oil
i would recomend m52 over m54 tbh m54 are not as robust blocks go with m52b30 stroker kit, but bettert results in the long run
Considering my low power goals, I don't think it'll make that much of a difference. We'll see.
The sea foam broke de carbon and and the rings have open more against the cilinder.
Yup!
I tried seafoam low compression on my 2012 ford transit connect xlt, it did nothing to improve my clyinder 1 low compression, just being honest
My guess is that the bottom of your valves were carboned up, and not seating properly, causing them to leak compression.
The seafoam probably broke up the looser carbon enough to allow them to properly seat, and that's why you saw the dramatic increase.
Fingers crossed!
Thats what i believe too! No way 10-15 years of burnt oil could be gone in a few days, even if you brush the piston with heaviest paint thinner cant do a set in a day.
I have the same problem its driving me nuts i did the sea foam today i hope i have the same luck as you 😢
Did it work?
Hell yeah
Hey do you recommend me to fix the head gasket on my e46 or just put a fresh engine
That depends on a lot of factors.
I'm really looking forward to seeing you get that thing back on the road😁 which turbo are planning to use? I've seen a lot of guys here in Germany run holset turbos(and hitting 500+whp), but I don't know whether they're cheap in the states too🤔
Same! I haven't fully committed to a turbo yet.
I’m on a gt3582 and it spools really quick.
Like 3800rpm 12psi
@DJ Coin Laundry I'm piecing it together to tailor it to my build. I figured might as well since a lot of the stuff is custom anyways.
@@straightsixracing what A/R is ypur gt3582?
Could it be the connections on your gauge? The o-ring in my adapter was torn, and I couldn't see it until I took it out and twisted it. Then, I could see how poorly it was sealing.
Anyway, I don't think there would be any harm in letting it dry out, testing it dry, and checking if your numbers go uneven and lower. Maybe that SeaFoam is softening the carbon on the rings enough to permit a seal, and it'll harden up and cause low compression when it dries out?
Could be. The surface of the spark plug hole was a little gritty as well so that may have caused a poor seal. I'm probably also going to try some Chemtool b12 when I get the chance. It should do a better job than seafoam.
Did it fix the problem permanently? Thanks
Any suggestions?? I have a 92’ e34 with low compression in 2 cylinders. I used the brand Restore once and not much happened. I did a complete engine flush and oil change. After that I used the brand Bars. I have another bottle of Bars that I plan on using but is there anything else I can do to solve this issue??
You’ll have to diagnose whether it’s a piston ring issue or valve issue.
@@nuisance_carl would it be best to rebuild the engine had about 245k miles on it but my dad suggested I just swap it with the same engine
@@INFAMOUSL1M1TZ_TL Either way works. I'm partial to just swapping in another motor. There's definitely risks involved with either option.
you're supposed to perform a compression test when the engine is at operating temperature. mechanics rarely do this
Sure, if the motor is already in the car. Nobody is putting that kind of work in when determining if their newly acquired motor is worth swapping in.
Dude i'm so stoked for you! You probably have already seen this youtuber, but his channel is Cody Aplin. He has an m52Tub motor boosted. In one of his videos he goes over various turbo setups for e46s and recommends A Garret GT3582 Turbo with a 82 rear housing for an M54 application. Anyways, can't wait to see your process as I have a stock manual 330i with the m54 myself! Heres the video that I mentioned. th-cam.com/video/Lf5l-nW9nO0/w-d-xo.html
Thanks! And yes, I've come across his channel before 👍
He has m54 325
DJ Coin Laundry that is true we don’t know and he is from Australia 🇦🇺 and the world may never know 🤔 😂 but I love his videos, and maybe one day we can all kick it and talk shit on each other’s cars
So that's a diesel?
I'm a noob in mechanic but I'm very interested
Gas engine 👍🏽
3.5 stroker kit would be different
I see you got the car running, safe to say it fixed your problem?
Yes, but the motor blew up lol probably tuning issue though
@@nuisance_carl sheesh lol I feel like these things always blow up lol
@@BronXTheBest There's plenty of good running M54's out there. People underestimate the importance of a tune (I DIY'd mine, so sums up why mine blew). Even the almighty 2jz's and LS's blow up from bad tunes.
@@nuisance_carl oh yeah for sure, everything blows up at some point lol. I’ve blown up more m50s than I can count, but it’s amazing that this worked for you!
How did it turn out..
Looking good so far
If you've watched the 50s kid you should know harbor freight compressor tests are bad. A bit late to the party but yep
Worked for me.
@@nuisance_carl yes they do work but you'll most likely get a lower pressure
@@djcoolkid100 Possibly, but I'm looking for cylinder to cylinder variation, not absolute compression numbers. As long as your gauge is repeatable (which I verified it is), then you'll be able to accomplish this.
Dude. Wow.
I have a Saab 9-5 Aero B235R with 120, 120, 30 and 150.
Saab technical in Sweden say gummed up rings.
Worth trying seafoam?
Definitely worth a shot.
have you tried it yet? what are the results?
@@BeeLineFab yep. To be fair I’m not sure it was the seafoam or just lots of cranking etc but the car runs perfectly and has continuous 220psi in each cylinder, which is indeed textbook
I have 6000 dollars spent already on this engine it will be my last try 😢
Your piston rings were gummed. Seafoam cleaned them
That’s what I’m hoping!
@@nuisance_carl 😂🤣🤣 wait why in the hell have you not cranked or started the engine? Is this some type of sarcasm? Where's the car?
@@ItsCertified I've started it. Just haven't let it get up to temps yet because I'm finishing up the exhaust.
@@nuisance_carl so checc this out. I'm having the same issue. I've tried the seafoam it worked but then the car cuts bacc off as if it lost compression again... I'm confused at this point
all good with the video great results but just a mention. This music is so annoying! I mean we can't listen you because the music is lauder than your voice. Better not to have music when you talk. Friendly mention don't take it wrong.
I welcome all constructive criticism. I've already started addressing that in the past couple videos by adjusting audio levels, but I continue to fine tune it with each video.
Use engine restore its better
any update since this vid? are you still seeing normal compression?
Haven't started the motor yet. I'll update once it happens!
Did your compression still the same!! Having the same problem going to give this a try
Haha stay the same
E G haha haven’t started it yet. Rip
Nuisance_Carl have you started it now
Thier was nothing wrong with you're engine you didn't show up that you even pur anything in thier it's a fake video just showing you're new engine
Damn you exposed me. Good job 👍🏽
