damn.... this week the same issue happened to my engine, it's like copy and paste

In my case, 3 years ago when i changed a valve, i didn't restrenghtened the head after 500km, and that is the cause the gasket failure in my opinion. When i taked of head 2 days ago, i found the bolts slacke.

do you guys use new head bolts. i believe they are expansion bolts and once stretched the torque settings will be out.

Did you check the manual for the right procedure to tighten the headbolts? It's a pretty special method. Maybe the gasket failure is due to not using this method for tightening and re tighten the headbolts?

the gasket failure is due to it running lean at 26 psi boost spikes an holding 20 psi

possibly an injector went down
