Compression test results. Comments appreciated.

Looks perfect.

That is good, no problem with valves or rings, nothing there to cause vibration.

I was reading some other treads about this and they say the pedal has to be depressed. I did not do so. How does it affect the test?

Looks on point. :wrench:

The readings would be a bit higher with throttle open.

As long as you tested all four cylinders with the throttle in the same position, the readings are still meaningful. You're looking for too much variation between cylinders. If one or more cylinders reads far off from the others, you've got a problem.

So, can I assume that the cylinders and rings are OK?

Yes.


When you had the cams out, did you make sure all the bearing caps went back in their original positions and orientation ?
If the bearing caps were installed incorrectly, this could cause the engine vibration and could lead to serious cam shaft or bearing failure.

You always want to do this with the throttle wide open.

Hello Tom,
The caps are still out. The new bearing cap screws are being shipped to the dealer and I will get them tomorrow. The cams are in correct order. The surface of the caps look fine. Can you tell about the cams by looking at the picture? I touched the surface there is no grooves or scratch that I can feel. It all feels smooth.

The cam journal at the bottom of the pic looks grooved, but that might be just the way the light hits it, it is not possible to judge a bearing as good from a pic.
You could check the bearings for clearance.
You have some metal shavings laying around, you will need to clean that up thoroughly.

That is correct, but I believe axenstar's test was adequate for the purpose.
