I have had the problem of sudden very low engine compression on three occasions and in different BMW vehicles. It is a complex process to repair but simple if you follow this video. This method does not require any engine disassembly or major cost.

My 325i just did this. When I get home I am going to try this.

My x5 did this after working on other parts of it for two weeks. What mileage are you at and did yours sit for some time?

@wrenchesinmotion3282 Месяц назад

@@leveluplife8585 I'm at 214k miles. I don't think it sat for more than three days. It was a total shock when it happened. Still haven't had a chance to work on it, hopefully today.

@@wrenchesinmotion3282 Gotcha, well I hope you figure it out. When my x5 didn’t start I checked everything else before compression of course so and when I realized I didn’t have great compression I thought 270k miles was a good run. Funny thing was it didn’t have any issue before it sat for the other work I wanted to take care of so I was scratching my head for a while!

@@leveluplife8585 just did this, and it fixed the car. Runs great again. Gave me a chance to change plugs, and you wouldn't believe what I found. 5 NGK Iridiums with the 4 straps, and one plain Autolite. Who does things like that? The video for this one will probably be up next Friday.

@@wrenchesinmotion3282 Wow, I’m surprised you haven’t been blowing up coil packs. The ngk laser platinums in mine have 60k miles on them from when I first got the car and they are darker than the set I took out back then. I then checked my ccv and my whole drain tube is clogged full of muddy thick oil so I am not in the process of putting in a catch can and cleaning the dipstick oil drain. It’s worth checking out so you don’t foul your new plugs at half of the expected life!

I will try this soon. My engine is not starting. I have checked everything, well at least the most suspected components and systems. I just have to go this way to see if it will work. I hope it will. I just need to find a good oil delivery method into the cylinders. Thanks so much. I reckon it took you three days to go through the process.

Hi. Nice job. My engine is not starting, Injectors, fuses, spark plug, ignitions all ok. Maybe low compressing.
