Is there oil pressure in that passage? If so, I doubt any cold patch is going to hold. Also, once it lets go there goes your oil pressure. If, OTOH, it's a drain, then your fix may be adequate.

I would not accept this statement at face value. (It may prove to be true, but more likely it would prove not to be true.) First of all, Diesel engines use compression ignition and diesel oils are...

Ohh! I had to run a car on that stuff once. I think it's about 65 octane! Anything over about 1/4 throttle and it sounded like someone had thrown a handful of ball bearings into the engine!

What do you mean by "approximately"? Forget everything else. This tells me you don't have spark, or it's way too weak, or it's occurring at the wrong point in the cycle. Even if the compression is...

The problem isn't the length, it is the profile of the "blades". Shorter blades still have the wrong profile.
