Good news is my Challenger Oil filter did its job...bad news, two tappets have gone bad...good amount of pitting. Not sure how it transpired, I fly regularly, use Cam Guard, and a dehydrator. Could be from prior owner but can't imagine it would take over 300 hrs and 3 years to surface...and we pulled a cylinder during pre-buy. Oddly enough it's on two opposing lifter bodies and others seem unaffected. I did catch it pretty early I think, less than 1/16 tsp of very fine particles. The particular cam lobe looks and feels ok no spalling and can't see any pitting...we'll see what overhaul shop says.
Engines ~1550 hrs and 30 years SMOH and ~ 650 hrs and 16 years STOH. Time for another MOH me thinks. To help me log some time towards A&P but mostly for the fun of it, I'm planning on doing this under the guidance of others.
Questions:
In the process of disassembly, bag-n-tag, and documentation right now.
Thankful for any input.

Questions:
- Recommended overhaul shops for steel parts and case. I know of Aircraft Specialties and Divco...any other recommendations? Based on a past leaky through bolt, I'm guess there's some fretting that needs to be worked out...Divco still the go-to place for this case work?
- Any special tools I should consider buying that will make things much easier or must haves? Engine stand?
- With the price of cylinders and backorders should just I have mine overhauled? I have ECIs not effected by AD and have ~650 since installed new. Compressions are all good 76-78. Recommendations on shop that will do it? Maybe in WI or Chicago area? Someone that will do a port and polish at the same time?
