I’m in the process of fixing exactly what your video talks about in regard to the front crankshaft seal. My best advice is check every single pulley on your and N55. Power steering AC idler pulley tension and police alternator even the crankshaft itself can warp due to the rubber deteriorating. Some brain surgeon put a smaller belt on this car, then was actually supposed to be there and it overstressed every single bearing that the serpentine belt rides on. Especially the AC and alternator. I’m going to install the belt guard while I have the pulley off for some reason it just seems like any oil leaks on these cars ends up on the serpentine belt no matter what. So keeping your oil leaks stopped or repaired as critical to keeping this engine in decent shape.
Hi, I'd like to express my gratitude for the fantastic video you provided. It was extremely helpful to me as I recently bought a 2012 BMW X5 facing a similar issue. Fortunately, I have a friend who owns a shop, and they've been kind enough to assist me. We've taken several steps to address the problem, including replacing the seal gasket coils, performing walnut blasting on the intake valves, and addressing the valve cover gaskets and control arms. Despite these efforts, the engine continues to run rough with misfires occurring across all cylinders.
Did you ever figure out your issue. Did you ever replace the injectors I didn't notice if you had mentioned that. Many people miss that. The injectors become clogged by the ethonal mixed in the fuel and other contamination. Just because your not getting a code doesn't mean it's not an issue.
Hi, thanks for asking about it, I did replaced the timing chain it was about 1/4 on an inch longer big improvement and performance but still running just a bit rough in idle. I am planning to replace the catalytic converter,
Hey bud did you ever change your injectors ? Ethanol cloggs injectors up see it all the time. What about the plugs Also clean your MAF sensors with the specific cleaners they sell CRC has a good one and lastly you should smoke test it because one small air leaks can do this.
28A0 got me here. Threw a belt due to tensioner malfunction. I didn't see any scraps behind the crank pulley but will smoke test and expect front seal blown.
I never thought I would hear about belts intruding into the timing cover area again on more modern cars after working on the City Intrepid police cars with the 3.5 engine, those had timing belts and they would throw the timing off and destroy the engines with valves hitting the pistons after the a/c v-belt would come off and get into the cover. But I'm crossing my fingers now that the used X5 I bought doesn't have pieces in the pan (or oil pick up screen), I know by the Carfax that the belt and tensioner were replaced and hopefully it wasn't because the belt was shredded. 🤞
@@jasonr2528 still no fix. I did smoke the valve cover and did not see no smoke coming from the front main seal. I think I have a small intake leak somewhere, I do here a small air leak sound around the intake manifold or valve cover. I’ve been planning on pressuring up the intake side with air and smoke. The code comes up every other day, the exhaust sound at idle has a little popping sound. Valve cover, intake seals have been replaced
@@xpert447 For a while I think I was getting a map sensor code. Cleaned both map and boost psi sensor, it did not help. I swapped the sensors around and code went away on map but came back to boost psi sensor. I replaced both sensors with original ones from FCP (I order all my parts from there) No codes for the sensors but still get that annoying P112F at times. Exhaust at times still has that popping noise
@@Fatfox806 I got that p112f the other day drove the car for the day the next day it went away for few weeks then happened again the other night and something drove for a couple hours went to start and it went away again and im not getting any vibration or sputter or hesitation either no loss of power so idk if its just a fluke or beginning stage of something goin bad and ideas
Man i checked my car e71 through an obd scanner and i have the same 2 codes 😢 just wish me luck And beside thank u for the video now i know wot to tell the mechanic to do exactly to my car
Yes, the X6. Im sorry to hear! P112F and 28A0 typically mean there is a vacuum leak somewhere. Start with smoking the intake and Valve Cover (through the oil fillup). Don't let the mechanic go down the ISTA repair plan, costing you hundreds if not thousands on diagnoses. But yes, have the mechanic watch this video and Like and Subscribe if it's helpful.
@@ShoppeRx Yeah i will do but I’m pretty sure its the crankshaft seal because at the day the codes appeared (btw no check engine light and i have smooth idle) oil light came on asking me to add some oil which i assumed according to what i read its a common thing and i start to hear a squeaky sound comes from the belts especially when i turn at low rpm . So when i saw your video and all what happened it does make sense now to me and yeah i will check the hoses for leak but for sure i will let him check the seal regardless .
Hi if I have this issue can I still drive the car?? Or no because the dry belt can get in the oil pick up tube, but what happens if that happens, can the dry belt actually get in the engine
"Drive" belt. And yes, pieces of it can enter the oil stream and clog up oil passages. If that happens, you are looking at a total engine loss. A very common occurrence.
Hey men i have the same car bmw x5 n55 engine and im getting this codes 28A0 and 2820 so basically i have to replace this part then ? Or it could be something else wrong in inside the car ?
Before replacing any parts, I would recommend smoking the intake and and engine through the oil fill. Check for leaks. 28A0 and P112F codes mean there is some type of vacuum leak somewhere. Rare cases it's something to do with internal engine issues, such as the camshaft drag, damaged pistons, etc.
@@ShoppeRx hey bro the code went away when reseting adaptation the car runs good the only thing is sometimes i get rough idle at cold start and warm but i think it might be a small leak somewhere i will do a smoke test to see thanks men 👍
p112f 2010 x6 can get it for 9500 kid replaced map and mass air. no fix what's your opinion on the p112f has light on and ocassionaly has a miss im told. found your vid thought id ask ya your thoughts thanks left u a thumbs up
I believe you have the N54 engine and not the N55 as shown. The N54 engine has issues with carbon buildup at the intake of the engine. I have heard of walnut blasting being a key to good breathing. P112F means you have a vacuum leak somewhere. Get the intake and valve cover smoked 1st and check for leaks

Not familiar with this but I would check the trottle body and MAF. Try reseting the Throttle Body and maybe clean it. This is a strange situation. Seems you have done everything.

Confirmed; wow seal gone. No scraps in engine so far. I will be able to fit my fiber optic cam in through the seal
Main thing is to make sure not belt parts end up in the oil pump. Hard to tell without taking off the oil pan.

I have been chasing the P112F code. Have smoked the intake multiple times, no leaks. I guess I’ll be smoking the valve cover next.

Who would’ve thought cheap plastic and cheap gaskets wouldn’t last much longer than the life of the warranty? I’m as shocked as the engineers must be.

Does anyone how long before the engine actually seizes
The problem is the white tool inside it is the problem. It is poorly designed. It depends on the brand of the seal .
