7mgte compression help

If you did it wrong what's preventing you from doing it wrong again?

You could tell him how to do it right... <shrug>

(yes, this is a backhanded way of asking for the procedure - or a link to it - I need to do this test someday soonish)

Why don't you follow the tsrm exactly? That way you KNOW you're doing it right.

Am I the only one that does that these days?

Ah, I never even thought to look there - duh. Is it still Monday? It feels like it inside my head.

The only thing i didnt do was disconnect the cps... which doesnt matter. I will disconnect it this time

So i got 175+- on 4 other cylinders and i managed to fuck up on 2 of them that aren't even next to each other how lol... i did the test right i just added too much oil cause i was pissed. and like the other guy said earlier, the cps being connected/disconnected doesnt matter

You probably put way too much oil in so compression numbers went sky high, and you possibly bent the rod in the cylinder. You can't compress that much oil so the connecting rod gave way and bent all to hell. Your engine is fucked now!!!! OMG, what'd ya do!?

Now that's entertainment.

Oh the irony :icon_razz

Lol I redid the compression test and got 180 on cyl 3 and 160 on cyl 6. Weird??? Now im breaking up under boost. 6Psi and sometimes from taking off from a stop or right after shifting. Im going to change the plugs.

Okay, so your second attempt fixed your compression issues. No need to rebuild the engine now. :icon_razz

Now to your break up issue. Did you have a break up issue before you started messing with your car? What's your spark plug gap for starters? At what rpm range to you experience the break up?

 

[Enano]

Yes i did have the breakup issue but far into the high rpms 5-6k. Now its breaking up lower. I think it might be my #6 plug its really red seems to have overheated maybe? I dont know what my plug gap is i bought the ngk iridiums from autozone and just put them on. I didnt have this issue before. Also i have spiky afrs that are never stable. 14.5-15.5 cruise and if i start going into boost i wont go rich unless i go WOT or go past like 10 lbs in which case itll go 10:1

Take the plugs you had in the engine while it was breaking up and check their current gap. Let us know what they were per cylinder. I'm still stumped on the red deposits on #6 cylinder. Maybe somebody else would know what was going on in that cylinder.

Your afrs that you described sounds normal to me.
