Are those cheap compression test kits on eBay any good? For $20 to $30 I'd much rather buy the kit since this probably won't be the last time in my life I'll have to do the test.

I'll probably change out the plugs since they're cheap, or at least pull them out to see how they are. I'm also due for an oil change.

Guess I'll have to have a friend help with the head gasket. Might wait till next summer to do it.

Thanks for the help.
