Why Apex Seals Fail

Barry Bordes · 06-04-2011, 12:56 PM

A couple of observations.

Detonation can be a cause of breaking apex seals but it is not a root cause.

Leaning out at high boost and too much advance can be a root causes, but how many of us run conservative maps and still have problems? There is something else going on.

Also, no one has brought up the warping of apex seals. Using OEM I haven't seen this. Can anyone share their experiences with this problem?
