05 EJ255 Compression results #4 wtf?! Bent Valve?

[05LegacyGTArmyguy]

Compression test results. Would #4 be a valve issue with the compression being none? Car runs and drives builds boost 120mph pulls no problem just rough idle P0304 code

 

#1 156 dry 165 wet

#2 155 dry 160 wet

#3 158 dry 166 wet

#4 12 dry 38 Wet <----yes you see that correctly. It tries to suck a $1 bill into the exhaust when I put it in front of the muffler

 

bent/Burnt Valve? Even a ring issue will have more compression than that yes?

 

Probably need to do a leak down next

Yes, the engine needs to come out, and at least have the heads rebuild.

 

The engine should be rebuild too if it has high miles and you plan to keep the car.

 

Burnt valves is a common issue with these cars that are on the factory tune.

 

Get the car Tuned when the engine is back together.

 

You should have the banjo filters removed too.

 

see my click here link for info.
