Many headers are also resonance tuned, to utilize the low-pressure reflected wave rarefaction pulse which can help scavenging the combustion chamber during valve overlap. This pulse is created in all exhaust systems each time a change in density occurs, such as when exhaust merges into the collector.
A leak in the head gasket - often called a "blown head gasket" - can result in a leak of coolant, the combustion gasses, or both. Blue smoke from the exhaust suggests that excess oil is entering the combustion chambers (although there are other possible causes than a head gasket leak). White smoke from the exhaust suggests that coolant is ...
The hottest cylinder-head temperatures (CHT) and highest internal cylinder pressures occur around 50 °F (28 °C) rich of peak EGT, and risk predetonation, making it essential to avoid that range, and operate either lean of peak EGT or richer than 100 °F (56 °C) rich of peak EGT.
The coil-in-cap HEI distributor was retired, and an all-new electronic distributor design was used. The intake manifold to head bolt pattern was redesigned to improve gasket integrity—four of the center intake manifold bolts were drilled at 72° instead of 90° for the cast iron cylinder heads. Changes to the valve covers were also made.
For 2001 Toyota started fitting factory MLS (multi-layer steel) head gaskets and other metal gaskets layered with Viton to engines, including the 5S-FE. MLS head gaskets require cylinder head and cylinder block resurfacing on older engines to ensure proper sealing; consequently, the MLS head gasket did not supersede the old composite head gasket.
It can also be used to make gaskets for mating surfaces: a suitable gasket material is held over the surface that needs a gasket, and the operator lightly taps around the edges of the mating surface to perforate the gasket material.
