I did a compression test, engine vacuum test, cylinder leakage test, and a cylinder balance test.


Compression Test:

Dry Test:
1: 120 psi
3: 118 psi
2: 118 psi
4: 120 psi

Wet Test:
1: 125 psi
3: 123 psi
2: 123 psi
4: 125 psi

Engine Vacuum Test:
With my vacuum gauge on my dipstick holder and with the PCV system plugged (finger on the valve cover over the pcv port). The engine pulled 7" of vacuum and the the needle moved pretty fast. My instructor said 5" of vacuum on that test is good.

Cylinder Leakage Test:

1: 8%
3: 10%
2: 10%
4: 8%
(My motor has 150,000 miles and that is really good, the normal leakage is 20% to 28% for a motor with 150k on it.)

Cylinder Balance Test:

With engine running it pulled 16" of vacuum. (hooked up to a port on the intake manifold)

1: dropped 2"
3: dropped 3"
2: dropped 3"
4: dropped 2"


With all of these tests done I was happy with my motor. I was scared to test it b/c the results might be bad. My intructor said that cylinder 1 and 4 are working a little harder than 3 and 2 for some reason.

I wish we had a dyno at school.

Any idea how much a shop would charge to do those kinds of test or how much the equipment would cost to do it myself?

Well I bought my own vacuum gauge ($20 at Sears) I think the compression tester is like $60-$100. And you need an air compressor to do the compression test and cylinder leakage. And they can get pretty spendy $70 to a lot of $.

I really don't know how much a shop would charge to do all those tests but I would bet they'd charge you over $100 for all of them. And probably over $170 if you went to Honda :)

Did your friend get you some prices for me?
Thanks a lot.

I emailed her but the one picture you sent only came out white, do you have a different one to send? What size were you looking for?

The stickers are 1" wide by 8" long. They are like the 3geez stickers you made so it has that masking stuff over the sticker. It has the DC logo and then it has the SPORTS after the DC logo. (The DC logo is the thing where the D like intertwines with the C )

The sticker I have is white so I can understand why it didn't show up good.

It didn't show up at all, when I opened the graphic file it was just one big white image. Can you put it behind somthing a take a pic or scan it?

I did scan 2 stickers. I will put a color sheet behind them so they will hopefully show up.

I scanned it with a CF vinyl background :D I figured it would be dark enough to show through the paper so you could see the stickers. I will see if it worked.

Nope didn't work it showed the cf good and just 2 white strips.
