When did I do my first engine rebuild?

When did I do my first engine rebuild?

I originally submitted the following collection of posts covering aspects of my first full engine rebuild experience to the type2 mailing list during the summer of ’97. They record the kinds of obstacles a novice rebuilder faces, as well as my personal observations and questions along the way.

Why does the Speedo pinion housing leak oil?

The problem lies within the speedo housing. The housing was machined to a close tolerance to accept the speedo pinion shaft and retard any leakage. In order to preclude any further leakage, the housing was also machined with a reverse scroll inside to draw the oil back into the gearbox as the shaft turned.

What should oil pressure be on a 1600cc engine?

I know that when the oil measured at the dipstick reached 180F using 10w40, the oil pressure would be about 10psi at idle and any warmer, would dip to 6-9 psi at idle, triggering the dash light. On long highway runs I’d see temps as high as 260F.

What should the temp be on a 1600cc engine?

On long highway runs I’d see temps as high as 260F. The next engine, balanced and full flowed, and with strict attention to tinware details, I expect to run considerably cooler.

Can a late model engine be pre oiled?

However, late model engines that feature a front-mounted oil pump that’s driven by the crankshaft cannot be pre-oiled in this manner. The use of a pressurized pre-oiling tank allows you to easily push pressurized oil throughout the engine’s oil circuit without the need to turn the engine’s oil pump (the LS engine is but one example).

When did they stop using break in oil?

As the EPA fuel economy requirements tightened, the need for less maintenance and better fuel economy ended the use of break-in oils as factory fill in new vehicles. However, the reduction of ZDDP (Zinc) and increase in detergent additives as part of the API SM oil specification in 2005, brought break-in oil back into play.

Which is better break in oil or ZDDP?

Also, break-in oils are generally low detergent (like the old days of straight 30, non-detergent for break-in). The lower detergent level allows the secondary ZDDP to be more effective.
