132-66 ROCKER ARM STAND, METRIC, REAR This part number is for a METRIC rocker arm stand for the Metric 1600 heads; which have 10mm studs. It could be used on an SAE head if the stand is drilled out. An SAE stand could bolt on a metric head but they have much larger stud holes in them. The risk with that is if the rear stand is improperly located or shifts the oil hole to lube the rocker arms and shaft could be partially or totally blocked because of the metric stud's smaller size. These are rear stands which differ only in that they have an oil passageway for the rockers. People not putting at least one rear stand at the rear position has been a problem over the years as the engine then starves the rocker assy. I've seen some actually begin SQUEAKING. Sometimes they will leave out the rocker shaft locator stud (which keeps rocker shaft from turning). This causes undue wear and the locator plug also serves as an oil gallery plug. With the plug absent the engine and especially the rocker arm assy looses a tremendous amount of oil pressure as the flow is erupting out the back tower instead of traveling down the rocker shaft. |
