Not getting oil to the pistons. Making knocking noise. Wont stay on.

Has the engine been run low on oil? Does the knocking get louder as the engine warms up? Have you had a automotive technician listen to this noise? Pistons don't really knock, the bearings in the engine called the crankshaft and piston connecting rod bearings do make a loud knocking noise, if that is the case the engine must be removed from the car and rebuilt.

How i can replace the cranksaft for a 99 honda civic ex

If you need to replace a crankshaft for a 99 Honda Civic EX, it may mean that there's more damage to the engine than is worth inputting financially for that service.

Is the engine knocking severely indicating a bad main bearing? If so, a replacement used engine may be more economical than rebuilding the one you have.

Good luck on this repair.

Is it possible to make a d15b carburator engine to a vtec

In my opinion it is not worth it. In order to make your d15 a vtec engine, you will have to put a d16 head on it. That will require drilling new oil ports, converting the engine to fuel injection, changing out the computer, and a whole lot more things. You would wind up spending more money doing that than just doing a d16 complete swap. plus the d16 will have more power over all anyway compared to the d15 vtec. d15 is a 1.5L the d16 is 1.6L reguardless your gonna have more power with a d16. Just a suggestion.

95 honda civic ex squeals when starting engine

Some of the grime, etc on the engine prior to steam cleaning along with any solvents used may have affected the drive/fan belt. I would suggest you either check tightness of the belt and possibly consider replacing it.

Take out a 95 honda civic EX coupe engine

Remove the large nut on the end of the axle. Remove the outer tie rod end. Remove the upper spindle mount. There is a cover over the bolt. Remove the brake caliper and the lower ball joint and disconnect speed sensor if equipped. Remove spindle and pull the axle out. You may need a large flat head screw driver to pop the sxle out of the transaxle.
