Burning Oil and Smoking After Rebuild - DA9 - B18A1 ... HELP!
I picked up a 1990 Integra GS 3DR CPE awhile back to modify and restore.
Per the previous owner, the engine (B18A1) (KL 5MT) was rebuilt in July 2010 with the following components, :
* JDM Integra Type R (ITR) Pistons
* JDM Integra Type R (ITR) Crank
* ARP Head Bolts
* ARP Rod Bolts
The problem is ...
It smokes on hard acceleration (light gray smoke ... oil control rings did not seat properly?) and I have *dry* black soot on the exhaust tips (running too rich?).
I'm using premium gas (91 Octane). The fuel filter is new, the PCV system and O2 sensor are functioning normally. An oil change w/filter was done 2 weeks ago.
Question,
* How long should it take for the oil control rings to seat after a rebuild?
* How many miles should it take to break-in a rebuilt engine?
* How is the fuel mixture controlled?
* Is the vehicle being damaged by driving it in this condition (burning oil ... oil control ring not seated properly)?
If it is determined after the leakdown test that it's the oil control rings, I'll need a competent engine re-builder to crack it open to take a look.
Right now I don't have the facilities to attempt it and the original re-builder has retired to New Mexico and is not available to do the work.
I'd appreciate recommendations to shops in the Los Angeles area for the teardown and reassembly. I am located in Culver City, CA 90230.
** Please PM me with any shop recommendations
Thanks, Paul

Does the car smoke at idle or under normal acceleration?
The valve seals could have easily been overlooked during a rebuild and is an easy replacement compared to rings.
The rings could be clocked wrong allowing oil to easily make its way into the cylinder or as you mentioned they didnt seat properly.
Test compression and see what you get.
The motor should be broken in from the time frame listed unless it just sat....

*smokes a little at idle when I start up in the morning, smokes more (not a lot) on acceleration, smokes a lot when you punch it around 4000 RPM.
Thanks, Known ... good to know about the valve seals.
