Low compression

[robmustang201528]

Noticed oil spitting out of my oil separator breather under boost figured I get a compression test. Car runs normal, no smoke still has plenty of power but the compression test says other wise. Going to build the motor. Tuner said I can drive the car but make sure I stay out of boost.

Here are the results

Looks like #6 was going too...

Was it misfiring too or just the oil spitting out??

I wanna run more boost without having to worry about my motor being on the edge. Couple people say just run E85 it'll keep you safe and you can run more boost.. yeah but then I'll be on the edge with my stock internals. Not sure if I trust anyone to build my motor around here so I'm thinking about buying a short block that's already put together. Something like the aluminator but not as expensive. Looking for something that handle 1000hp. Forged rods and pistions. Any suggestions? Thanks

Sorry to hear that .... but you already knew you were on borrowed time back when you posted that . Lol
Car must have heard you and thought let’s do it NOW . Lol

Just oil spitting out of the oil separator

Lol exactly. I figured it was coming. Not even mad. Just have to build it stronger.

No misfire. No codes

Broken ringland on those two cylinders is my wager.

I plan on building it but not right now. I'm thinking if I stay out of boost I should be fine. I'm hoping anyways.

I should probably get one done on mine too .
I am wondering if it’s hurt since it seemed down in mph compared to others but that was the whole of last season .
It picked up toward the end with the fall air but 143 mph trap with a 3.25 pulley (Gen 5 ) is 4-5 mph slower than others .
My car runs fine too , no noises or blowing oil or anything. Got some logs recently since I swapped out my winter tires and they look great ..

I have been procrastinating getting it done as want to have my new long block ready to go if needed .
Short block is done but I decided to get new heads and have builder assemble the long block .
