Diagnosis of New Motor symptoms !!!!????

[talonpower]

First off ... Its a brand new Magnus stage 3 motor and freshly rebuilt head on with a new turbo and all ... In order to break in the motor and turbo, I have been running 14 psi with the rev limiter set at 6500 rpms .... the car has been tuned (very loosely) by marco on a wideband and is running extremely rich ( black smoke under acceleration ).. SHOULD I BE CONCERNED?

facts:

- The car does not hold idle because I have a huge TB leak so I have to be on the throttle at all times and sputters a little bit at 2500 rpms but feels fine once out of vacuum and in boost .... car has always had trouble idling but its never been this bad (since I got it back)

- my oil pressure gauge used to read nearly as high as the gauge would go for the first 200-300 kms but for the last 800-1000 kms usually reads less than 1/4 on the guage, even when I floor it it doesnt even get to 1/2 .... at idle the needle is not even visible ... it just hops up once I begin driving ....

- my PVC breather is smoking (perhaps a faulty PVC? blowby already?)


To anyone who is knowledgable about breaking in motors and break-in symptoms ... please let me know your thoughts .. What should I be concerned about? what should I not be concerned about?

If you can log your car and the short term isnt subtracting a constant high(or large negative number) then you should be fine.

If you didnt break in the motor by taking the motor out and racing(revving) to the desired rpm you want the motor to spin to then the rings may not seat and yes you can get blow by from that. What you should have done when it was first started and ready to drive go out and do a few runs at full boost and at the rpm you want the engine to rev to when its done breaking in. Damn you other countries and your damn metric system!!!(j/k ) I would get a real oil pressure test done as apposed to usiong the stock gauge.
