Has any one out there used US Chrome?
In Wisconsin, correct?

Their primary* clientele are 928 owners. I sent a 944 S2 block to them and had it bored and replated. Sorry to say - I have not completed the rebuild on that engine and therefore it's not been tested. The service was good, the appearance seems good. Can't fault or praise them without a proper test.


* subcontracted?

Just be sure to inspect it carefully and also get the matching "cover" that goes with the particular version.
Yes that’s my plan, I’ll scour some of the other forums and keep an eye on eBay.

Do you know if LN approves of their process? Or is this just about geography?

I just located a set of good engine cases from a 2001 3.4, any problem using these with my 99 engine internals and cylinder heads?

The 2001 3.4 cases will be fine on the 99 3.4 internals. But check the cylinders carefully with a "bore gauge" to see how "round" they are, they can go oval pretty badly. If they are out-of-round check with Hartech/Alpine to see what they charge to re-round and install support rings.

Thanks for the information Porschetech3. The cases that I’ve located have been serviced by US Chrome and recoated with Nikasil.

We use Millennium, however we have our own standards for finishing and extensive QA program in place for any cylinder or block that is plated by Millennium for us.

For the blocks, they are pressure tested before and after sleeving or direct plating and are measured for ovality/taper as well as RpK, RvK, and Rk.

We stock many blocks available on exchange including some with direct plating in stock bore sizes, where cylinder cracking is not such a large issue, however that's bascially for Boxsters and base model Caymans. Too many cylinder issues with the other blocks to risk direct plating or even considering overbores.

Thank you for the clarification. Do you currently have a 3.4 to 3.4 or 3.4 to 3.6 996 case in stock for exchange?

Inventory fluctuates daily. We have 3.4 blocks in stock bore sizes with Nickies available, however I'm not sure if all our oversize blocks are spoken for as I am not in the office today and can't put my hands on them. Best to give the office a call to verify at 815-472-2939.

So to make sure I understand... If I ordered a set of 3.4 cases they could be shipped out shortly after being paid for. Correct? And you would or would not need my engine cases as a core?

Thank you Charles,
Carl

Yes, we theoretically could ship the block immediately. We would have to charge a core charge if we do not receive your block first, which usually most customers would prefer not to have to pay, so they typically send us their case first so we can evaluate it to ensure there is no damage that would prevent us from reselling it.

Default Crankshaft

Nice rainy day to get a little work accomplished. Cleaned parts and installed new main bearings and laid the crankshaft in place. Measured CS end play. Waiting for the rest of the rod bearings to arrive. Ordered 6 rod bearings forgetting that 6 means 6 half shells not 6 pairs...


Crankshaft polished and cleaned.

Main bearing housing and oilers cleaned. Waiting for the new main bearing shells and thrust washers to be installed.

Crankshaft carrier assembled.

Crankshaft endplay checked and measures .005”
