final blog


For my grade 12 class project, I worked on a 2007 Honda Civic that was donated to my school. The owner told us  that he 
had to put oil in regularly and could tell something was wrong. The problem with the engine was that it would burn oil and 
informed us that he did not want to spend the money to fix it. Also, we found out the clutch was worn out as well as the 
engine which meant  I had to take out the engine and do an engine/ transmission rebuild. My goal was to finish taking out 
the engine before November and have it built and ready to go back in the car  by the end of the semester. I was looking 
forward to getting this project done and learning not only how to fix the engine, but getting the chance to blog and explain
 the processes to doing so.   



The problem with the car was that the engine was burning oil. After doing research, I found that one possible cause of the 
burning oil could be the piston rings. If the piston rings can not seal the cylinder wall, then oil will leak into the combustion 
chamber where it will burn. I had taken all the spark plugs out and did a dry compression test and wrote the results down.
 I then had to add a few squirts of oil into each piston and did a wet compression test, and wrote the results down.

One problem I ran into was taking off the shift linkages. The problem I had with taking them off were the 2 little retainer clips
 that held them down. The way I solved this problem was by using a pry bar and a hammer to lift them.

I learned how all the parts of an engine come together and play a role in the running of the engine. It basically is like a 
giant puzzle. When faced with a problem, I would try a few things instead of just asking my teacher. I noticed that I was
 more prepared to try and problem solve first. Other times, I would involve my teacher because I did not want to break a
 part. 

Since I had to work on this car alone instead of as a group of 4, I had to manage my time and work fast. The expectation
 was to have the engine in the car before the Christmas break and then fix any problems after. But I was able to put the
 engine back in the car and connected all the pieces to the engine. I also was able to test the car and had it up and running
 with no problem other than replacing one spark plug before the break. I have learned a lot more than I would have 
thought, probably because I had to do all the tasks.  I also learned that things will not always go perfectly as you expect
 them to. So you need to have the patience and ability to work through the problem and resolve it.

The first thing i did was taking off the hoses that were connected to the radiator. It was difficult to get some of them off but I used a flat head screwdriver to loosen them. The next step was to take off the clutch slave cylinder. After, I took off the plastic air cover to get a better access point to taking off the sub frame. My partner Adam removed ball joint nut, and removed the axel nut from outer wheel hub right side. He also rear engine mount, and axel. Took off belt, and drew a picture to remember how it works. I moved alternator, and labeled AC.

The engine is out. The first step is to see what the new engine needs from the old one, and move the parts over. The wiring harness had to be moved over to the new engine and it is very important that the correct plugs were connected into the right spots. It is important because we would not know if there is a plug in the wrong spot until the engine is back in the car and we have done a test run. If there was a miss connected plug, then we would have to take the engine out again and figure out whats wrong. Some hoses had to be removed and transferred over to the new engine. One hose was too long to be connected so we had to cut it and make it the right size. I had to move the power steering pump over. I was careful to make sure i put it on the right way because if you turned it upside down, the bolts and the holes would still line up which made it look like it would still fit. Moving all these parts over, was a slow careful process because there were times where we woul...

What is the problem?:  The problem with the car is that the engine is burning oil. After doing research, I found that one possible cause of the burning oil could be the piston rings. If the p iston rings  can not seal the cylinder wall, then oil will leak into the combustion chamber where it will burn . I took all the spark plugs out and did a dry compression test, then wrote the results down. I then added a few squirts of oil into each piston and did a wet compressi o n test, and wrote the results down.  Step 1 To find out the cause: I did a dry and wet compression test. Results:  compression test (dry) 1st cylinder - 150 PSI 2nd cylinder - 90 PSI 3rd cylinder - 150 PSI 4th cylinder - 120 PSI compression test (wet) 1st cylinder - 150 PSI 2nd cylinder - 130 PSI 3rd cylinder - 190 PSI 4th cylinder - 160 PSI After the tests, I compared the two charts to see what the results are going to be. The results show that the wet comp...
