Default Re: Oil Capacity of 345 v8 needed

I believe the standard fill level with filter change is 6 qts for SV8 engines in light duty vehicles. I've seen both 5.6 and 5.7 listed for the 345. It must be somewhere in between. I've never really worried much about the metric measurement.

Thanks for the help. Oh, do you think I should still add an extra qt / oil?

1 liter = 61.0237 cubic inches.

I'll let you do the math.

HRM, what you describe sounds like the classic spun cam bearing that many IH SV engines suffer from. The best way to confirm this is to pull the pan and look for chunks of cam bearing in the pan. This typically happens when starting an engine that has not run for a long time. The cam bearings are long way down the line in the IH oil system and take a long time to receive oil. Hence on a "dry" start the bearings tend to stick to the cam and spin. I've had this happen to 3 IH SV engines.

For some reason these engines seem to tolerate this condition for long periods of time and many thousands of miles, so it's probably not a critical must fix now condition.

Looks like I'm going to have to drop the pan then. I'll let you know what I see. 1975IH200: looks like 5.65L, dead center

Fortunately these pans are very easy to access.

Replacing a spun cam bearing is not so easy though.....
