2nd 964 Engine rebuild: Reusable hardware items?

[Infinite1]

Hello all,

I hope no one mindes. I asked this over in another forum but haven't received any responses. So I figured I would try here...

To give some background. I acquired my 964 in 2018. It had 197k miles and was a driver. I knew at purchase the car needed an engine rebuild. After about 3 months of waiting, I took delivery of my full engine rebuild. Split case and all. For the past 6 years it has been a solid daily driven car. Even had some fun, autocross, and spirited driving during the pandemic when there was no one on the road. Fast forward to beginning of this month I took the car out on it's maiden voyage on track. Things didn't end so well.... Root cause is still pending but after doing some diagnosing with the help of fellow forum members the oil was drained and found metal shavings on the case drain plug...

As the title suggests the engine will have to be dropped and case split again. In the current state of everything being budget conscious on a rebuild is high on the list of goals. My question for the experts would be. Is it possible to re-use the hardware from the first build? For example, I have 993TT (Part # 993 101 170 51) head studs. Are they re-usable? While I understand this could be answered by my engine builder. I curious to hear secondary opinions from other experienced builders. Thanks in advance!

Yes, your 993TT head studs (993 101 170 51) are generally reusable if they show no damage, corrosion, or stretching, they're high-strength steel, not TTY. Other hardware like rod bolts and gaskets should typically be replaced, while main studs and case bolts can often be reused if inspected carefully. A thorough check during teardown will help decide what's safe to keep.

Dilivar head studs are a non-magnetic alloy, not steel per se.
