How to do leak down test on FRS
 

So I got a CEL the other night and lost power. Cylinders 1&3 misfiring plus random misfiring code. Oil everywhere in my intake system. I wanted to do a leak down test to get a better idea of what is going on. I'm hoping it is my turbo seals went bad and oil went everywhere, and then fouled out the plugs causing a misfire.

I wanted to see if anyone had any tips or useful info specific to the FRS. I didn't see a DIY guide on how to do any compression or leak down test. Maybe I'll make one? I've done it before on some older Detroit and John Deere diesels, just never a small engine like this. Looks like it should be fun getting the hose threaded in the spark plug hole. I've seen someone say they loosen the motor mounts and jack up one side at a time to get easier access.
