    Cel misfire in cylinder 3. I pulled the new plugs found some oil on them then ran a compression test. 180/90/0/180. The first test for Cylinder 2 was 120 then I retested and it dropped to 90. Cylinder 3s tests started with 0 and stayed at 0. I noticed oil in the plug holes as well.

    Perhaps it is time for a rebuild.
    Did you do a leaksown test as well? Courious which way the air is escaping. Maybe a valve is not closing?

    Sup, Jaris! Glad you posted. Post up mods, etc. A welcome into thread is common practice, it's here where you should do that. https://mazdaspeeds.org/index.php?forums/new-member-section.86/

    Guys he had a misfire cylinder 3,used my compression tester and bam. He was spewing smoke from his k04, so he went Corksport, hpfp, accessport, ebcs, then got the misfire. I didn't know how bad it was running before this. CEL finally came on after the money put into it.

    I know @FattiMotorWorks has salvaged motors, edge has rebuilt, and 1 shop in Atlanta can build forged. Sucks.

    Those compression numbers are ugly, did you dump alittle oil in the cylinder during the compression check? How many miles has the turbo been on?

    Stock ko4 blew two weeks ago and this was a lot of oil lost and burnt. The new turbo has been on all of 2 days for about 9 miles

    There was smoke before the new turbo. When the new turbo got in the rear of the oil in the exhaust burned out. I have a feeling this this was an issue when the ko4 blue originally. The tune didn't have anything to do with it

    Drop a cap fuel of oil in the low compression cylinders but it's looking like rebuild time

    Leakdown test time. You might be the luckiest guy on earth and it just be a busted head gasket.
