Obviously at this point I just need to leave my engine work to the pro's however I simply enjoy working on the engine.
I rebuilt my /6 engine as a 9.5:1 compression 2.7l. When I first put the engine in the car and tried to start it a few months back, I had found that my kids managed to get a 13mm into the #5 cylinder which damaged the head. I had the head repaired and put everything back together and started the engine. It starts ok however there is a very loud noise which is obvious in the video. Background- I put oil fed tensioners in as part of the upgrade. I did not prime them with oil on installation. When I had my issue with a mug in cyl #5, I did not replace the piston cause there was minimal visible damage. There was no apparent damage to the cylinder jug. I did not check the con rod cause I didn't remove the cylinder and piston when I was fixing this issue. Any ideas of what could be the issue? To me, it sounds like the chain is rubbing on the case or something like that. It is so loud though that I cannot really tell where it is coming from other than the drivers side of the engine. My big concern is- did I damage my con rod when I had my 13mm in cyl 5 issue. I did the test where you pull the spark plug wire on the cylinder that has the con rod issue and there was no difference in the sound. http://youtu.be/X7Y2XqGN3Fc |
