Valve guide moved

sgkent said:
if the head has not been off, do a visual inspection with a bore scope on the piston. You may find that the pushrod was bent when the piston and the valve met. That can be because the piston cracked and broke into a top and bottom, or a valve hung open. The leak can be either the hole in the piston, cracked piston or a broken guide and bent valve where air is leaking past the guide. Usually that will also show up in the intake or the exhaust.

I don’t have a scope.It did sound like some air movement around the valves also But mostly out of the dipstick. The plugs got slightly oil running it just for a couple minutes so I’m guess rings or piston.
 
Good workable borescope $20 https://amazon.com/dp/B07PBF6DX5?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_9

nice bore scope $49 https://www.amazon.com/dp/B0928Q3T42?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2&th=1

Really nice bore scope $129 for 5', $10 more for 10' https://www.amazon.com/DEPSTECH-Articulating-Articulated-Industrial-Inspection/dp/B0DT16R78W/ref=sr_1_1_sspa?crid=351YHVQORYEB0&dib=eyJ2IjoiMSJ9.7tY6VTCHYFCqHccEaGzh-KuDrrl5vznyq-QCVVhJGKFNRskDh0B9g7RN668bt2OXlPWIINfCpl1MbUI5YwGXQf6i3vGQGJ2IYGjPM3Dfd0sawDb5GBnbPtp9RyyQKYSlDTYsltmWh_hN8wac663RumVPal3YhleEMxdiPPMR2v0hj8UmPvFVTjn5B5anowEj5fT3nenNJiH3gE0JhUOiAYZSqrq7JlgwcbKixWOE9T1A1yBwUv9ymk0hlaEcs988oUbVbiP4T3vrPB7tWuPA7k5j2uWDYn9HFOb4jUqiXf4.Ykj-Ff3xpkCHmu0R6-k5hmhJk91JXQS_gI0PY4_JsL4&dib_tag=se&keywords=depstech+borescope&qid=1757368424&s=industrial&sprefix=depstech+borescope,industrial,152&sr=1-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1

Thanks I need to get one
 
Had a similar situation. Per advice on a different site more than 5 years ago, i put red thread locker on the exposed valve guide, tapped it back into place and peened around it. I let it sit over night, reassembled it all the next day, adjust ed the valves with new push rods where needed and i am still mowing with it today. Nothing lost by trying.

Working on a v twin briggs(44t977 -0015g1) with a bent intake push rod. The valve guide is pushed (has a spring,rubber seal on top)out slightly higher than the exhaust guide. Can anyone tell me how much the guides should stick out of the head?
Thinking about readjusting and peening valve guide.

Is that your "problem" ? It's not a problem.
 
I peened mine like I saw on you tube. After two mows, I checked on it again and it started comming out so I ended up just getting a new head.
On mine, but the rod snapped off. I was able to pull the broken end out with a magnet through the oil fill. Lucky it was the steel one.
Good luck.
