Can An Engine Start Too Quickly?

My point exactly. That oil film is very thin if the engine has been sitting for very long and is easily pushed through within the first rotation. Dry start time is a very real thing in a time where oil is lacking more anti wear properties than ever.
Jeepdaddy probably has the best idea, Power Punch or Lucas Oil stabilizer is probably a good idea for an engine that will be sitting for weeks at a time.

 

It may be the hillbilly in me but this thread reminds me a bit of a local guy. Super sharp, but he is a bit eccentric. He bought a new Honda Monkey as soon as they came out, and it is still at the Honda dealer, because if he takes delivery it won't be new anymore!

 

There are in fact people who own "zero-mile" Harleys, 30 years old, kept in glass cases.

 

I’m going to throw this in here. My lathe is old, 1942. It has no oil pump and no true bearings. It is a hardened spindle running in plain cast iron serrated bearings. Similar but way cruder than car bearings. It runs 10wt non detergent machine oil in it that is fed with a wool wick on the journal and has for 78 years and has spun way more than a car with 500-600,000 miles on it. Starts every time with a load on it, no oil pump and would always be considered a cold start. The spindle looks beautiful even after all these years. You guys are worrying about something so insignificant it’s pitiful.

 

Yes, exactly as Mcruff said above! if you're worried about something that's been sitting for decades, unhook the coil wire and crank... It probably has many other issues anyway! Cheers!

 

Exactly. Worry over insignificance, especially these days with the modern materials, and more important the modern lubricants. Years past it was amazing for an engine to make it 100,00 miles. Nowadays with modern materials and lubricants not uncommon to reach 250,00-300,00 miles with proper maintenance.

 

That crap has plugged up more oil passages than I care to think about.
Lifters that need to be pumped up have the check valve that is not working correctly
So that is not an oiling issue but a lifter issue. Unless caused by lack of oil maintenance. Typically dirty oil or other problems cause a lifter to not hold pressure or to pump up immediately. If multiple lifter don’t pressurize immediately then I would be looking at the oiling system.

A wise person once observed, "they would not argue so vehemently if the stakes were not so small." Or words to that effect.

Or as a friend told me, "any thread with more than ten posts isn't worth reading."

 

I wouldn’t be concerned starting an engine that has been sitting even for a year. That oil is still in the bearings and in the oil pump, so there is oil pressure almost instantaneously when it starts. Now a new engine that has never been started, thats a different situation.
