Onan intake valve seat
Posted: Mon Feb 06, 2023 7:39 pm
So I have a p216 with a loose intake valve seat on oil filter side. Tractor was bought 3-4 years ago. It's my 4016ps project. First thing I did when I pulled it in the garage was a compression test and oil filer side 50psi. Pulled head and found valve not seated to seat. Pulled valve cover and a little inspection found the seat loose. Stop into our towns engine machine shop. Was told they have done this repair several times. Was told a week I'd have it back. Stop in 4 weeks later and not done. Was told to stop in before the end of week and it would be done. Gave them the benefit of the doubt and just stopped in today end of day which gave them a few extra days and found he dropped it on the ground. Valve not seated all the way.Not properly machined into block. Grabbed it unfinished. Still needed to be machined to valve. Got it home and rough measuring with my dial caliper makes this seat .20 taller than the other side. This seat is sticking past the face of the head surface and the seat isnt in fully pressed into block. Made some calls tonight and talked to a few very knowledgeable men on onans and who are current onan dealers and builder/stores. Lined me up with a machine shop that has done this work on onans for 30 years gonna give them a call in the am and see if this is repairable.
