I have a 89 crx, with a 92-95 d16z6. brand new 16g turbo from a eclipse, 450 cc injecters, dsm fuel pump, hondata s200 p28 ecu. street tuned alittle only for full throttle right now, runs alittle rich on low to mid throttle. d15 vtec cam. problem is, i just put new piston rings in the motor, runs stong when warm, been doing the break in cycle, car is tuned for 9psi right now, but only been pushin it to 5 then shifting. but has been smoking alot and burning some oil when cold then stops after a while of driving. i have been told that you need 400-500mile break in period but also heard that the rings are broke in after about 10min. if this is true. what do you think is causing the oil burning to happen in the cold. need suggestions!!!! thank you

 

The piston rings are probably gapped too big. When it's cold, the oil burns but once the engine warms up, the piston rings expand from the heat...so the burning goes away.

Break-in takes a few mins. Not 500+ miles ..

 

Hey thanks for the input. what do you think i should change to get this fixed, its kinda of annoying and i have put alot of time into building this car. i just wanna fix it. let me know thank you again

 

but i still want other insights to this problem, if anyone else has any other idea's. also to ad, i used stock honda rings, that should have been gapped from the factory, but i have noticed this afternoon it was smoking worse then this morning, very very clueless!!!

 

could also be valve seals or guides, cus after they get warm that expand also

 

yeah thats what i was thinking the same thing. i have not gone through the head yet, i just put the cam in set the valves and called it good. i should probably get that checked out. but its down time on my daily driver. i am thinkin about getting a seperate head and sending it off to get a good treatment on it and then switchin them. thanks for all you help since i am new and all to this site
