In this video I talk about the inner workings of the Timing cover and one of its functions as the housing for the oil pump. I go over the passages and how the two bypasses work. I also cover some of the easiest mods anyone can do to their cover to reduce the amount of stress on the gears that drive the pump shaft. The one thing I try to make clear is that any mods you do will not help an engine in need of a rebuild, you can buy yourself some time by installing a high volume gear set (HV for short) but other wise no mods will help an engine that does not offer resistance to flow. From the Buick Manuals, I have gathered that anything around 10 PSI at idle is normal anything better than 37 PSI @ 2400 RPM is acceptable.
Don’t forget to check out the IG and Facebook pages for the channel where I post almost daily all the little shenanigans I encounter day to day driving my Buick Grand National.
