How long before rebuilt engine rings seat? EDIT. Help a 1st time engine builder.

I just read through the thread, and was glad to find a happy ending!

I hope you at least got your money back for the rings...

glad to find a happy ending

+1 :)

Glad to read your conclusion, I was going to say beat the absolute shit out of it and see what happens (couldn't have hurt?)

I've had motors that burn oil, and then properly beating the shit out of them with a few fresh, frequent oil changes, loosens up the oil control rings......then all good.

Glad you had a happy ending.

Yeah, I think you blocks bad too.

;)

congrats on the great outcome

OP, glad it worked out.
Stanley, could have been the block initially. Who knows all r3v can do is speculate. It is easier to figure out with the motor present.
In the future, there should be 4 rings per piston. Top two, then two more to complete the oil ring, that is each oil ring should have a top an bottom edge.

great thread. great ending.

im in the process of rebuilding my first engine as well and found this thread inspiring.

I reused the same block, nothing changed other than a rehone. I don't see how "bad block" is a proper diagnosis. If it had a resleeve done correctly then there is a proper sealing surface for the rings to seat. No secret magic going on to cause excessive oil to burn.
Not to be an ass, but I reused the same block just to prove a point.

I'm glad my thread helped others out. It was definitely a learning process for me and you very quickly realize how many people don't know as much as they think when it comes to fine tuning and precision troubleshooting. I used to think my a close friend of mine was a Master Mechanic until we started troubleshooting this issue.

This isn't necessarily true...

The top ring or compression ring can just be a standard flat ring like mine was with no top or bottom.

The second ring or scraper ring from my experience always has an edge to it that must be positioned to scrape oil off the cylinder walls into the crankcase.

And the third ring or oil control ring can either be a two piece or three piece design as commonly seen. Mine was the two piece design as shown but was missing the inner tensioning spring the first time.

And the problem is solved!!!

My car has been down a year. It's so nice to have it running again.

I just read this thread all the way from the first post.

Congrats on getting her up and running. As someone who just got my first engine in and running a few months ago after a lot of pain and frustration I know how good it feels to finally get her up and running.

[brianao34]

Thanks man. I can't stop driving it. Haha

[brianao34]

Also, just got off the phone with Frank at Deves Piston Rings and they will be issuing me a full refund.
But I will never be doing business with him again. He even went as far as to say that the 2 piece oil control ring doesn't even need the spring tensioner so it didn't matter that I wasn't sent them on the first shipment from him...very bad customer service.

[bmwstudent]

Seems strange they would say that the spring tensioner isn't needed. Why would it be part of the set if it wasn't needed. Sounds like he was trying to blow smoke up your shorts. Happy to hear you got it sorted.

[NeedaE30]

I'm super pumped for you man

Has anyone else ever sliced their fingers open on piston rings? lol last time i put rings on a piston i forgot to wear gloves and sliced the shit out of all 5 fingers on my left hand... so stupid, next time i build a motor i'll be sure to remember the gloves and this thread just in case haha

got any videos of the car running? that would complete this thread
