The good the bad and the ugly
Recent post got me to thinking .
What do thing was the best engine " of it's time "
NO wrong answers here this is just based on peoples experiences.
Me personally think the Onan P220 - proven block design, reliable ignition system , ample power without being too fuel hungry. with routine maintenance will go many thousand hours of use . (going off personal experience )

Re: The good the bad and the ugly
I think the P series is that way, my P216 and P218 just run and run well. P218 is heading towards 1500 hours, doesn't use oil, doesn't smoke.DavidBarkey wrote: ↑Tue Jan 23, 2024 7:03 pm Recent post got me to thinking .

Re: The good the bad and the ugly
B block with p heads. B blocks had better valves and seats. Build from there with 20hp cam. Use p ignition. If I were to build one that is.

Re: The good the bad and the ugly
Curious , what is different in the valve and seats that make the B blocks better ?

Re: The good the bad and the ugly
B block has thicker valve stems
B valve stems are 11/32. ( .343 )
P valve stems are close to 9/32 ( .280 )
I don't hear of b blocks loosing a valve seat. Just p blocks. They changed to thinner valve stems and the valves couldn't carry the heat enough?

Re: The good the bad and the ugly
The thinner valve stems likely improve airflow by making more power. With more air flow you can add more fuel making more power and more heat. My "I don't own an Onan" understanding is the head overheats which causes the valve seat to come loose. Does the oil filter side exhaust valve usually come loose?Jancoe wrote: ↑Wed Jan 24, 2024 8:38 am B block has thicker valve stems
