Since christmas time is coming around, I was looking at picking up a compression and leak down tester kit for my garage. I was wondering if anyone knew of a reliable brand to go with. I have heard the harbor freight is reliable after you swap the one gauge on it, but Id like something that I dont have to modify. Let me know what you guys are using and what youd recommend. Thanks!

 

I bought mine from Jeg's, but Summit has them too. All they are is two gages with an orifice between the two to give you a differential pressure.
Jegs
Summit
Jegs compression
Summit compression
Or you could spend big money on this one. Buxton

Hope this helps

 

I bought the Matco part number CLT2APB and order all the adapters I could for it.
