Damn sorry Billy! What oil do you use?

[Soonerbilly]

rotella T6

[Soonerbilly]

Don't think it has anything to do with oil....been using for a while and my buddy uses it as well.

[robnitro]

I was just curious, as I don't think the 30 weight ll04 oil is good.

Hi, i have a late 2008 LCI E90 335D. What numbers should i be seeing for the compression test?

I have an issue with the engine and its gone into the garage but i did a test and got 0 on cylinder 5 and getting 260-280 on all the others.

What reading should i be seeing so i can check when i get the car back.

Thank you

wow, this amazing thread gone silent since last November.

Curious if Billy fixed all the issues with new bearing and new head studs

running stock tune?

any tips on the reinstall of bearings and head?

as far as compression test for sameen, my only comment is that the compression numbers should all be the same... is it running?

[Soonerbilly]

Is not running....it kinda got put on the back burner. Now I'm waiting on some CAMS and springs from Colt and Whitbread performance. Had a hell of a time getting the correct bearings, SEVERAL aftermarket companies had oil hole alignment issues, so I ended up getting them from BMW. Should start going back together in the next 2 weeks.

I just replaced timing chains etc so, if you have any questions, let me know.

wow, did u replace it on ur own? that's a huge job. why did you replace it? it's meant to last lifetime, even tho I heard it's recommended to change at 150k.
also, what was the state of the chain itself?

the term "lifetime" is not literal. it should be "life expectancy". the manufacture lifetime of most modern engines is only about 150k. with that being said anything that is "lifetime" needs to be changed eventually.

335dsleeper is a M57 god a long with a few others here. he was ban from the site for too much awesomeness.

[Soonerbilly]

Replaced because you're already in there....so why not.

[alex sol]

please post pics of the work! i'm preparing to rebuild. seized due to oil starvation... rod / crank bearings?? head / valves? not sure what yet... likely need a new chain at the very least

doing in my garage at home.

[BB_cuda]

Soonerbilly, did you get the engine back together? At least tell us of recent progress please. thanks

I'm am sort of puzzled why low compression on cylinder 4 would in anyway relate to spun bearing on #6 rod. I presume you heard engine noise before ever starting compression checks.

[Soonerbilly]

^^^Yeah knocking at the end of 2 runs at the strip. Was never really bad and would kind of come and go. Decided to open her up and look, found the spun rod bearing.
I now have all my parts( got the colt cams, upgraded springs, some head work ) starts going back in on Friday, but now that its summer i'll be at the lake quite a bit so who knows how long this will take.

[32valves]

any updates on this rebuild

[Soonerbilly]

Motor is back in car...awaiting DDE and getting all the vacuum lines and top end stuff hooked back up....should be ready to fire up this weekend.

[Soonerbilly]

She's back on the road.....HUGE thanks to BRR/Ryan/335dsleeper for all the help. Cant wait to get all the little kinks worked out and get her back to the track.

[335stoner]

I should have the newest tune update this Friday! Can't wait!! I'm getting all of the carbon cleaning stuff soon then it will be dyno and track time! His tune is amazing! I have driven a jr2.8 and dudmd stage 2 he really has something awesome going with his tunes.

[Soonerbilly]

^^^What all mods you have?

[335stoner]

Just the ABC deletes (vrsf and gutted scr) and the afe filter.

[Soonerbilly]

Cant wait to see your numbers.

[335stoner]
