Thickness of Goetze and Mahle rings for 944 engine was equal, if it were even remotely similar difference you showed on the photo, obviously I would not have used them.

I think something that has come up a lot especially with the internet and ability to sell through multiple (non legit channels) is counterfeit parts.
Not to drag up an old thread, but I've been doing a little research on building up my short block and replacing bearings. Rod bearings is a no brainer, I'm questioning if i should replace the mains. The short block is about 100K miles that I am using.
Hello guys, the Glyco H006/5 STD differ from the one which came out of my 1984 NA 944. On the image you see the Glyco left and the original ones right. The top row are the upper bearing halfs, the bottom row the lower bearing halfs. Compare the bottom row of bearings. The new ones do not have an oil channel for the lower halfs, while the lower halfs on the old bearings do have an oil channel. So the original 1984 bearings come with a 360° oil channel, and the new ones with only 180°. The original as well as the new ones were both stamped Glyco. So definitely, when you buy Glyco, it will differ from the factory 944 equipment. Question for me is: Are the new bearings some kind of update and possibly better than the original ones? I doubt it. I think I am going to buy new OE parts instead of using the H006/5 Glycos. What do you think? Comparison Glyco vs. OE
944 Bearings....
Main bearings in the 944 are not an issue, and if they go bad it's due to another issue. The Glyco replacement bearings are fine, but like any engine part they should be examined for defects.
Rod bearings are a different story. Neither the Porsche bearings nor the Glyco's are up to performance use - they're too soft. There's finally a good off the shelf solution: ACL Race Rod Bearings / 944 Porsche. Some vendors sell them for big $, but they're now on the web quite inexpensively. Use Google, and be sure to get the correct sizing (usually STD). They will serve you well and protect against the myriad of rod bearing failures in the 944. Just an example: https://944store.com/product/82-91-p...d-bearing-set/
Thank you for your responses . In the meantime I found a page in the WSM, stating the later (85/2) closed main bearings can be used also in earlier engines. Oil to the connecting rod bearings is supplied by two holes inside the crankshaft. One of the holes is always connected to the channeled bearing. The closed bearing belongs to the lower crankcase half.
