^^ good deal Cass, glad to see you making progress and DIY FTW

 

BMW 335i.




Oh yeah, it has had trouble with overheating... requiring addition of an oil cooler.

 

Congrats Chris.... She lets you spend money on your car... So she has to be a nice person

Raj.... Did not think you would fall into my trap... But you made my point....a stock car from BMW is having issues because of lack of cooling .... Just think how our platform in FI is handling that heat.

 

I knew you were waiting for that example

 

This is isn't a failure of the VQ. It's a failure of the machine shop for not choosing the right size bearings which is vital and they have to be extremely precise. That's why I'm looking for a machine shop with laser equipment to measure crank journals and ID of rods. No oil cooler is another problem. And that EMS I never even heard of is probably another.

Cant pass the blame to the VQ. It's only as good as it is built. Cant spin to 8k without a girdle and c caps. Cant run without an oil cooler. Cant run it without proper torque specs and sequences
They got a lot more problems than just cooling. You wont hear about it on e90post though.

 

this is true. They have a some issues. Modding a 335i may seem cheap because it is already FI from the factory.. but to get 350-400 out of those cars is tough.. and going for more power.. it will get a lot more expensive than FIing a Z.

Trust me i was about this || close to switching to a 335i. Kept the Z instead.

 

It Begins... this was the easy part.


The coolant looked normal when I purged it, but the residue has dried into a chalky substance. Is this normal


This is the bolt I had to diesel off and the tools it took to make it happen

 

The hose with the cannister attached to it was routed through a coolant hard line and won't let the engine drop and pull out. In the second pic you can see the turbo pipe is so close the the timing covers that it wouldn't squeeze through. Problem was solved by using a tie-down to put pressure on the pipe, applying some lube to the pipe and covers and pulling the hose out and up through. DIY WIN


Fuel system dismantled. If I had thought this through better I probably could have kept this intact and diconnected the main lines under the car instead. Just making more work for myself


This is the oil that came out of the drivers side IC pipe connection. I was suprised by it, so I didn't have anything in place to catch it.


The money shot.... engine is F***ed for certain

 

Blame the machine shop for choosing the wrong size bearings. Either main crank bearings or connecting rod bearings.

Or

Blame who ever put the rotating assembly together for improper torque specs/sequence.

Or

Lack of a billet main girdle.


Really sorry to see that. I would be pissed. I would probably cry too.

 

Pretty sure the 1st two are the same place. I have always had good luck with justice in the past, but it is upsetting to see these preventable failures.

 

I really hope you x the 2 shops that have touched your car so far. **** as this point you might as well make it a full DIY. I'm sure it will last longer then any of these motors have.

 

WOW is all I gotta say. Chris is I were you, Id be in a lawsuit with 2 shops right about now.....but thats just me!

 

Yea but the first 2 were built by one shop and the 3rd was built by another. Both are very reputable engine builders, exactly the same failure....low oil pressure leading to failed bearings. to me the more likely COMMON scenario across all three is elevated oil temps. What happens to oil pressure and what fails first when you cook your oil?

 

Until you see a build spec sheet on this motor these are 2 ASSUMPTIONS and theories. It's easy to blame someone else but you have ZERO info to base that off of.

 

And this coming from a person who "Called out" owners in a thread on his IPP motor even after admitting the dealer (NOT the engine builder/IPP) took the car out in boost when untuned. You may have not blamed them but their name is in the title of a "calling out" thread where it is OBVIOUSLY apparant that it is NO issue of theirs. I just don't see that as right by any means. Everyone wants to point the finger right away at the person who put it together, which I think is sad.

TAKE RESPONSIBILITY for what happened the first time AT THE DEALER. Don't call the world to arms just to see if maybe you can get something for free....and hopefully by chance others may have a little issue so you can build your army.

 

How does my issue have anything in common with Chris'? I never once blamed my issue on IPP, I blamed it on the dealer from the beginning. Chris has had the same failure, THE SAME FAILURE, 4 times nows. If my IPP block had the bearings eat themselves 4 times in a row and I had to foot the bill everytime I'd be in a lawsuit also. And when did I call out any owners other then asking if they have had any similar problems with my motor? I simply created a thread to see if anyone has ever had a blow by issue like mine, to rule out the possibility of anything other then the dbag at the dealer that took my car out. If your block failed 4 times at the hands of the same people the same way and you had to foot the bill everytime would you not be looking towards a lawsuit if that shop wasnt willing to investigate and help you solve the problem? Its clear someone, somewhere along the line of Chris' build isnt doing soemthing right. Also no one would be pointing any fingers at the shops that built it if this hadnt happened 4 times. Shops make mistakes sometimes, sometimes the owners themselves make mistakes that the shop couldnt prevent. BUT having the same thing fail 4 times is not at the fault of the owner, its not like Chris takes his car out everyday and races it on a track or drags it, trust me I know. Thats all I saying.....

 

I can't believe Justice machined the block wrong. I have the specs saved in an email somewhere for sure. Jim was VERY aware of my status and what I have been through with this car.

I find myself thinking of the recurring failures and how and when they happened. It makes me wonder if the oil cooler has been the FAIL point all along, on every engine. All the failures have been when its real hot outside, mid-summer or so. Possible my kit is heating the oil to the fail point and it has never been seen because I don't have a temp gauge

Either way, if I rebuild I will be sure to have Defi oil temp, oil pressure and coolant temp gauges installed in the center console as well as running dual oil coolers since I'm a sucker for symmetry.

 

It has to do with this thread b/c you're like every other person in here EXCEPT Chris. Point blame left and right with little to NO information. As soon as Chris finds something to point another direction you'll ride that train.

We ALL want to help him here but pointing him to assumptions is NOT helping him.

My problem with your thread is you placed a name of a reputable company in a thread to see if they could be to blame for something. When in all actuality you were of the opinion that the dealer did it. Please correct me if Im wrong but I saw that thread as seeing if you can go back against IPP when you KNOW something happened that is NOT warrantable and could EASILY F up a motor.

 

Jon - I'm almost done working for the day.... want to pull this bish out of my paperweight today?

 

Hopefully the community (and the shops involved) learns something from this instead of pointing fingers at the builders and each other for the 4th time in a row.
