Thanks for another great tutorial, Kurt! I sometimes binge watch your videos. If you ever get the chance, would greatly appreciate a video on "no brainer" things everyone should absolutely do to a 3.2 while you already have the engine out of the car. 👍👍
Kurt, you said in this video that you are not a fan of regrinding cams. Is the concern with the integrity of the material after regrinding and heat treating, or something else? Also, other than a visual inspection of the cam, looking for scoring or pitting, are there any measurements that can be done? Thanks again as always for your knowledge and insight.
Chris, I have a number of issues with re-ground camshafts. The biggest issue is the smaller base circle and the change in rocker geometry. The other issues I have encountered are with the pattern used to grind the cam. As a rebuilder, there is not a lot we can do with measurements other than bearing size and a visual inspection. If you want to do more, then I would send the camshaft to Glennyee Motorsports. Glenn has a cam analyzer machine that can accurately measure the camshaft lobes and timing. Kurt
@@klassikats Thanks for the response Kurt. I'm disassembling a 3.0L out of an 82 SC. I have experience rebuilding engines, but not with Porsche. I'm seeing things that are questionable to me from a reuse standpoint. Things like cam box bearing surfaces, camshaft, and cylinders and pistons. I have not completed cleaning and measuring yet, but when I do, I wanted to do a consultation session with you to get your opinion. I know you will be limited in what you can tell from pictures or a web conference, but I want to gain insight from the discussion. Is that something that fits within your consultation service?
@@chrismac2264 That is a perfect reason for a meeting. When you are ready, you can check Kurt's calendar for a time that works for you. www.klassikats.com/consultation-services/ Thanks, S
Almost nothing is hard to find in the 911 world, just very expensive. Mahle, CP, JE, Wössner are all respected sources for air cooled pistons, probably a bit controversial but dare I say in this order....
Enjoy your work. Both members of the team. Thank you.
Thanks for watching!
Kurt
I could spend all day watching Kurt and would love to just hang out and shoot the breeze and learn
Thanks
Kurt
@@klassikats That would be my idea of big fun, too.

Thanks, S
@@klassikats Thanks, will do.
Always great to watch and learn from your videos. Are OEM SC pistons hard to find and what will you suggest for a replacement set? Thanks.

No Pistons are not hard to find. Although sometimes Mahle will tend to run out as it seems that they doing limited manufacturing runs these days.
