Compression Results

Reading those plugs, your car is running insanely rich.

Did the leak down. Ring failure on cylinder #4. Got to tear her down.

Thats a huge drop in cylinder 4. Do leakdown to confirm that it is not the rings. If it is the entire engine has to come apart again. Who built this motor for you?

I did the bottom end. The machine shop did the top end... Yes. Will do a leak down of course.

The wet/dry test though shows no difference on that cylinder. That's a good sign but I won't count my eggs til they're hatched.

The wet/dry test on cylinder #4 give me hope that it's not the rings but the valves. Or perhaps the head gasket.... hmmm

Ok. On to the leak down test...

So my car is burning oil after this rebuild. It's a 2.7 stroker on an iX with 9.8:1 CR.

The car also has a tough time starting.
So I did a compression test. Here are my results. Sorry for the chicken scratch. And 'Dry Max' means I cranked the engine dry the maximum number of times to reach the highest compression... (Usually 10 cranks or so). The regular Dry Test was 5 cranks for each cylinder.
I noticed the plugs for cylinders 1-4 smelled like gas, too...

I will do a leak down test next. Just wanted to see if anyone had thoughts on these numbers for the compression test. Thanks!
