looking for compression tester

[Smokey Eddy]

Looking for a compression tester. Southern bc. Right next to the border to WA.

I bought on of these of ebay a couple years ago and have been happy with it:

Great thanks for finding that for me!

Wayland, would it be possible for you to post a picture of the tip of your end which you screw into the injector hole? In other words, the point at which the pressure enters the tester.

I just want to compare the tip of it to my Mac compression tester. There is a reason I want to see it if at all possible. The reason is that my Mac allows pressure to enter directly in the middle....leading me to think I should leave the old heat shield in the hole....even though the Bentley says to take heat shields out when using the official VW compression tester.

I tested my friend's engine the other day and leaving the heat shield in yielded about 50 lbs. more per hole.
Thank you.

Well the shield will take up volume that would otherwise be compression loss.

I'll get a pic as soon as I can. I think I left the heat shield in last time I used it. My tester has a sort of adapter sleeve thingy with two copper sealing washers. I think this is because it's designed to work with a multitude of different motors. This will all make more sense once I post a pic!

I had a problem with my car one time when that happened.  There was such a huge air pocket in the fuel line that I thought it the fuel line was full of fuel.  What I did was take the in and out banjo, look inside to see if there was fuel to the top of the fittings.  If there wasn't, I filled the IP with ATF because it was a little thicker.  Then I had a empty plastic bottle, filled it up with diesel, and ran a piece of fuel line with an inline filter to the in banjo, and ran a piece of fuel line from the out banjo to to the plastic bottle.  That way, if the car started and ran, I could better diagnose the problem, be it a fuel issue from the fuel filter back, or stuck vanes inside the IP.  Hope this helps!
