Strange sound from rebuilt engine...

particles' bronze color reminds me of two internals, rod small bearings and valve guides. And since there is oil on top of cylinders, just thinking of the latter

Hi Peter
I really hope that things are not as bad as they seem to look. I rebuilt my 993's top end last year and have for various reasons not had the chance to actually drive the car properly since. I am giving the car it's first proper outing tomorrow. My issues have been oil leak related. I really feel for you and am hoping for a good outcome.

Can't offer any advice or help Peter, but watched this intently from post 1 and been rooting for you all the way.

Update: A Tale of Two Filters
Cut open the filters with the appropriate tool. Photos below. Just a couple of notes first. I will show this in several posts as there are a bunch of pictures.
1. The large filter has been in the car for the last 800 miles (pre-rebuild use).
2. The small filter is brand new (post rebuild use only).
3. On visual inspection the small filter had very little metal - a few tiny particles found.
4. On visual inspection the large filter had many specs the largest of which was about 1/8 inch long. There were thousands, most very tiny.
5. The large filter has what looks like little pieces of plastic - could this be loctite 574, something else? See pic 4.
6. I used two magnets: small filter magnet is 1/4 inch diameter. Large filter magnet is 1/2 inch diameter.

Is this right???
The large filter is for oil coming back from the engine. If there is engine issue, it would be caught by this filter.
The smaller filter is for oil coming from the tank into the filter.

Those are large pieces, bigger than I would have expected, especially since all you need to wear in was cams, rockers and guides. I did not split the filter on my rebuild, but the oil I dumped had lots of particles in it, but non that were this large that I found. Maybe Steve or someone can comment.
Well, engine is out so you might as well dig in. How is the disassembly going?

Yup, and since he has picked up particles in the large filter, its stuff from the engine, not the tank.

I am down to the long block sitting on a furniture dolly, exhaust removed. Waiting to coordinate 3 people to help me lift it up on to engine stand. I tried w/ me and one other. Too heavy. I think I will continue on and remove/inspect the rockers, Cams, the Cam Tower/Head assembly as a unit. I find having it on a stand is soooo much easier though so I might wait.
