My car would smoke when first started up, then clear up, when i got on it it felt as if I hit VTEC, Which I am assuming was the 4th plug clearing out and start firing and then Lots of smoke came out the exhaust.
It could be your piston rings, it could be you have a bad valve like I did. If you still have the stock d15b7 engine thats in your car, Now would be a good time to swap in a better engine. Even the JDM D15b and ZC VTEC or D16z6 are good easy swaps. If you get a replacement engine I would recommend getting an engine from Japan as opposed to a worn out US Market Engine.
If you want to keep this engine, I would recommend doing a compression test and see what your numbers are, If your numbers are low put a little oil in each plug hole and see if they go up. If so its probably a Ring issue.
If you have good numbers such as 180ish, Its probably a bad valve.

Another great way to find the problem would be to do a cylinder leakage test. that will tell you whether its a burnt/cracked intake/exhaust valve, or piston rings, but to do so, you need a leakdown tester.

Depends on what you get, a JDM D15b (VTEC not VTEC-E) go for around 500 plus shipping.
You can get them on either hmotorsonline or tigerjapanase(Engine + Transmission, Engine Only).
Your local import shop might have them as well, Make sure you get a VTEC version of the JDM D15b and not the VTEC-E Model, Both say D15b as their engine code hoever the vtec-e model has "VTEC-E" on the valve cover, the VTEC model has only "VTEC"

if you and atleast 1 more person do this you will have it swaped in a few hours. trust me its cake. i hardly even got my hands dirty doing mine. but i swaped in a b seris motor, not just the same motor. and it was my first honda swap. i didnt have a manuel. but the haynes repair manuel is the best one so when you start the swap and run into any problems you can come on here and ther will be someone to help
egsedanguy wrote:well it is easy. all you need is a basic tool set. 6mm,8mm.10mm,12mm,14mm,17mm and a axel socket. braker bar, jack, and thats about it.. like i said it was also my first swap when i did mine.. jack up the front, remove front wheels and remove axel nut, and lower ball joint. then slip the axels out. next diss connect all wires from motor, and radiator hose, power steering line and fuel line, be sure not to lose the 2 copper washers from the fuel line, also just pull the radiator out to guve more room. next you need to unbolt the header from the exaust then disconect the shift linkage. once you have done this you will have 2 staibleizer mounts in the front, the mount on the pass side, driver side and on the fire wall. and blam it will be out.. you can take the motor out from the bottom if you dont have a engine hoist, just have to get the front up as high as possible. just use a jack to help lower the motor down and slid it out. then repeat backward to install.
