Engine compression, where can I get a gauge to check it?

Hi guys I still have not been able to check the compression with a gauge due to the fact I can not find one. Can anyone tell me where I can find a gauge to check the compression on my engine to see if it is blown?

You can buy a normal piston one at Walmart and use it as described by RotaryResurrection.com -- Worked for me.

I just got back I bought the gauge. Before i do anything maybe you all can give me some advice.

1987 turbo 2 doesn't start.

1- if one of the apex seals are stuck wont the compression test look like I have a blown seal?

2- if I use oil and squirt it into the bottom rear and front housing to try to free up any stuck seals prior to doing the compression test, when I do the compression test after trying to free up the seals, wont the left over oil clog the inlet for the compression valve?

What do I do first and how?

Do I Check compression first then oil the seals with egi fuse out?

OR oil the seals with egi fuse out then check compression??

Anyone please help me.
