Mind you I am not losing any oil either I've seen this happen a couple of times and I am almost certain it is a ringland issue as it is very common for these cars to have those issues

[@jamesb1856]

I hate to doubt Alex, he's right way more than wrong. But I've seen that before as well as a long time former Ford tech, but it wasn't on a coyote, so my thoughts may be invalid. If possible, pull the valve cover and run the engine and see if smoke is coming through a valve seal. I saw it one a boosted new edge cobra. But given the common issues with these cars, ring lands are more likely, but not 100%.

[@travisc.3881]

Also Alex, before going through the trouble of swapping long blocks, rent/buy a cylinder leakage tester to help further pinpoint where your compression loss is on #7 cylinder. It’s possible that a valve seat/spring issue may be the problem instead of a ring issue.

[@YDBT4LIFE]

It's puffing smoke from crankcase....tell me how that is valve related.

A little trick we started doing to avoid the crank time exceded is use a relay tester and use that on the starter relay. Then ya can cruise threw it like any other engine, and not have to wait like 10 minutes everytime ya get locked out.

[@hansjochen6257]

You might consider adding a tiny bit more piston ring gap for the new engine.

[@brianbrown7501]

If you hold the gas pedal to the floor it and crank, it puts the car into "clear flood mode" which automatically cuts fuel and spark.

Compression checks don't work for broken ringlands. What you check for is oil on the threads of the plug.

Great video Alex! Sorry bout your motor, I bought a complete long block for my 2018 was 4200 with my buddy’s discount

[@YDBT4LIFE]

I have both, a long block and a shortblock. might just get a brand new shortblock from ford through pbh

[@preston6882]

Keep in mind a majority of that vapor at idle can be that the PCV valve isn’t functioning correctly at all. I would remove the catch can and check for vapor again at idle.

[@philipherman99]

Good video. Good information.

[@TheLoneWolf_andCoyote]

i'd pull the shortblock down order some .010" over 2618 CP Carillo 10 to 1 compression pistons with tool steel pins & napier piston rings, torque plate hone the block, deck it with a BHJ decking fixture and rebalance the rotating assembly and maybe some custom camshafts from Comp cams with a later intake closing and stuff it right back in there. A little less on the static compression won't hurt it and probably help it down in Florida with the bad gas. If it's soggy just change the pulley on the Vortech and let it eat that's amazing that the little motor is doing as good as it is especially because I know you've put it threw hell and back.

[@YDBT4LIFE]

I won't ever lower compression on a coyote. Makes 0 sense.

[@jennytalia1465]

Alex by the way if you hold the gas pedal all the way down as the car cranks, it’ll enter flood mode and turn injectors off so you don’t have to unplug injectors. Saves me some time every time I do a compression check.

[@YDBT4LIFE]

Better to disconnect injectors

[@horsepoweraddiction808]

You are probably right about it being a ringland. But it still could be a lifter/lash adjuster, damaged spring, cylinder damage. It’s time for a leak down test.

[@themaveric32]

Can't you just replace the ringlands? Why does the whole shortblock have to be replaced?

[@AB-coyote]

During the summer in GA I run enough Boostane to achieve 96 octane just for added safety. Car has a 93 tune and a GEN2R with a 85MM pulley. I used octanium before and it didn’t take long at all for my plugs to look like yours. With Boostane the orange affect for me has been much much less.

Alex, Ford tech here, just for future reference you can push the accelerator pedal to the floor with the key on, and the PCM will go into Clear Flood mode, meaning it will not pulse the injectors. And then you can turn the engine over without it starting/spraying fuel for a compression test.

lol I think the schrader valve was missing on the first compression tester. Not that it matters because you found the low cyl, but even the good cylinders seem a bit low. I consistently get between 250-290psi on gen 3 coyotes from doing so many oil consumption diags. That 12:1 compression should almost hit the top of that gauge.
