Covers, shields and housings enclose and protect engine assemblies, direct fluids where they are needed, and keep radiant heat away from components that cannot tolerate it. This group covers rocker and valve covers, timing covers, flywheel and bell housings, gear housings, heat shields, guards and inspection plates. CAT engines in enclosed generator and marine installations rely heavily on heat shielding to protect hoses, wiring and sensors from radiant heat off the exhaust and turbocharger, so a missing or damaged shield has consequences beyond the shield itself. Cover leaks are frequently blamed on more expensive components: a distorted flange, an over-tightened fastener or a blocked breather raising crankcase pressure is the more common cause.

A distorted flange, over-tightened fasteners, a reused gasket, or a blocked crankcase breather raising internal pressure. The breather is the one most often overlooked.
Yes. A distorted shield no longer protects effectively and may contact and wear adjacent components, exposing hoses and wiring to radiant heat.
Yes, and usually to a low figure. Over-tightening distorts the flange and causes the leak the work was intended to fix.
