BMW 335i Front Main Seal (full install) after Belt EXPLOSION!!
HTML-код
- Опубликовано: 5 авг 2020
- What happens when you blow your serpentine belt on your 2008 BMW 335i E90? It completely shreds, wraps around the crankshaft pulley and pushes in your front main oil seal which then gushes out oil! Sounds pretty traumatic right?!
Well luckily for you, the repair isn't! Watch along and see just how easy this was for us to complete!

Thumbs up for a good video showing that portion of the job. However once the timing chain chews up the belt the little fragments clog the oil pickup and can cause oil starvation. I will be dropping my pan and cleaning it out as just draining it is insufficient. Also some of the belt can get carried to the top of the timing chain and caught up there as well. The valve cover needs to be removed and the cam timing gears checked as well. E90post has a good thread on this all too common issue. I will be adding the protective metal bracket so this never happens again.
I like how you actually show the process literally , nice vid bro thanks
It is incredible. People are upset over how a man decorates his garage.
I think its a bit risky doing just a seal without taking oil pan and valve cover to check for belt debries. Most likely they are all over the engine.
If you guys has the same problem (belt sucked) unfortunately you will remove the oil pan to clean inside small filter inside
Great video showing the steps to replace the front crank seal and how the serpentine belt damaged it in the first place.
Just stumbled upon your channel. Awesome video Devon, really helped out with my n54 project 👌
Keep coming back to this video for help.. I’m happy because this is the only video for real help with the n55/n54 seal job having the engine still in the engine bay makes it easy for me because I’m doing it this way as well
I really appreciate the comment! Thank you 🙌🏻
@@DevonsGarage I have to do some cleaning too of the belt material, but I got the seal off one quick question you barely moved the crank. Is that because moving it too much can damage something without the belt on? And without harmonic balancer. I may have to move it a bit too
Mine is doing same thing leaking a lot oil blew up 3 belts , I replaced oil coolant housing and nothing … tmw I will check crank seal thank you guys !
Bro you deserve way more subs! I’m from San Luis Obispo!
I appreciate that man! Yeah I was watching your video of the M3 update and noticed the CA location! I’m only about 3 hours from there
The shop wanted $5800-6500 to do the rear main seal on my BMW 335i with 80k miles. That's insane. What's more insane is rear main seal leaking at 80k miles. (The valve cover gasket leaked around at around 60k miles!!!) Not fixing at the shop, needless to say. So I"m driving my Lexus RX with 237k miles. No oil leaks at all...amazing.
The video perfectly shows how the belt gets sucked in there. I didn't even know it goes that far in to the motor.
Great video. It took me many attempts to, with all bc the screws. I had to rotate the crank to use a new location on the seal with the screws for each attempt. I used a torch to heat up the block around the seal, may or may not have helped. Finally got it
looking at all the caked on oil on the front of the block, this is just another reminder to change out your OFHG's and not let it get bad enough to leak on the belt system and cause this huge failure
Has the seal failed after this? Same thing happened to me and kept blowing the seal after :/
nice work. how’s it running
If you still have the car, how is it running now? Did you have any other issues after this repair? Thanks!
I was wondering what was involved with removing the old belt from the internals. Nice video. Go out and buy yourself some medical hemostats for reaching into hard to reach areas like you were in. I just today installed my crank seal guard to prevent this from happening if my belt decides to shred.
Same thing happened to me last week! I’m doing this process right now... did you remove the valve cover to see inside? Also did you remove your oil pan to check that the pool pick up to isn’t clogged and full with bits of belt? Wondering because I’m seeing other videos and some do it.. thanks your video helped me a lot
omar carranza I personally would of myself, but the friend I was helping didn’t care too much since the car was turned off pretty quickly after the issue happened. So I said alrighty then lol. But it’s been running well since, he’s been driving it like he stole it 😂
Based off what I have been reading I would do it as precaution. If you don't check it though and a low oil pressure light comes on stop quick or else the engine will blow up.
@DevonsGarage since it's been a year now. How long did the engine last after this? Lol
I have a question bro! Do you have to use that sealant from fcp specifically? Is there any other sealant I can use? Thanks in advance
It’s been a little while since we did it and my buddy bought the kit, I think honestly we used that sealant because it came with it however I bet if I did some research some high quality black RTV would work too but don’t quote me on that, I would have to compare them before I gave my own approval haha
What did you guys use to stop the seal from moving while you removed the bolts ?
You could use power ratchet or have the car on the ground and engage the parking brake.
How much do you charge to fix it😭
Lit
No oil for PTFE seal
Good job guys! Like open heart surgery lol.
How much of the belt debris was probably sucked into the oil pump pick up tube?
Well, it’s still running well today, so I’d assume not much. He daily’s the car. Thinking he got lucky but others may not be so fortunate
How do you feel about doing this job again I’m
From Bakersfield lol
don't you use the primer then the seal?
He did, @10:30 he describes how to prepare for seal installation.
Pieces will be in oil pan and oil pump pickup, some might even get on to the camshaft area. You have to drop the oil pan (fun, even more fun if you have xDrive) and the valve cover to look and look and look.
Yes you are right as I also knew as well but my friend wasn’t wanting to do all of that part so we left it as is. It has still been running very well to today with normal oil changes. I don’t have the best hope though as time goes by but maybe he’s lucky since the belt snapped as they we’re pulling onto the street to their house so it didn’t run much or at a high rpm, don’t know
@@DevonsGarage how's the engine now
@@TheChris91173 still going strong, he is doing new injectors this coming weekend due to the normality of being a N54 lol but otherwise all has been ok. Maybe he just got lucky out of many
@devonsGarage what size screws where they?
Should have invested in one of those guards for the front main seal, I'll picked one up from eBay for about 60
Did you have to remove the radiator
no you do not have to remove it
8:25 so painful to watch 😂 all you needed was needle nose pliers….
I agree lol had to work with what was given to me being at a buddies house
@@DevonsGarage I understand man non the less y’all got it done and super professionally not like some half assed backyard butchers 😂 respect
@@aimized1460 appreciate that man! The only thing I would of changed personally would be to drop the pan just to make sure there were no pieces on the oil pickup like many in the comments have mentioned BUT my friend didn’t want to do that and hey the car still runs today!
@@DevonsGarage for sure if the belt got shredded I would also drop the pan extra work will pay off in the long run, and plus a healthy engine is a good engine ! Cheers man
Love the Trump banner. Nice video guys!
incomplete and improper repair as the oil pan needed to be removed to clean and remove debris. Have done many of these belt repair jobs and not one could I have left the oil pan on due to belt pieces in the pan.
Luckily this one has beat all odds and 55k miles later, she’s still going strong. I recommended the oil pan drop but my friend did not care too much to go that much into it. It’s definitely a risk but one he was willing to take
I am the one dislike....for reasons. And you don't need a fancy tool to do this either.
One dislike from me as well, same reason!
