I decide my t1 oil pump in my 2056 was doing me no favors with a smaller than ideal OD.
I still had the T4 oil pump from the 2.0 that was doing its job when I had a cam thrust bearing fail /knock, so I decided to pull it a part for inspection.
I will perform some measurements and get it cleaned up, if it turns out to be in good shape.
The pics look like a great core.

Phil,
This build and the last build had a total of less that 100 miles the Failure again was the top end intake valves and guides. Ill post pic of the worn out valve guides
The bottom end seemed OK. but erratic oil pressure problems I am sure added to the guides issue

Also The Crank end play had .0045 when assembled and CHECKED
I added the rear main and the play went to zero . Sound like a familiar thread others have seen.... I continued any way thinking the seal was adding the buffer to the clearance. I had howling bear noises and the wear pic on the side of the thrust confirmed it was tight. Looks like new bearings and pump for bottom end I will check the saddles for possible line bore

interesting about the guide wear, and the crank end play. I now have 2500 miles and recently had developed what i think is a RMS leak - again, after replacing it when i did the transmission seals about 10 months ago. So last night i pullted the motor and today will pull of the trans to look at that and im going to check the cranksaft endplay , i have heard that too much play will cause the leak, but maybe itd just a bad VR seal so i got new Ehrling.
am i correct that the crank endplay should be tested with no seal? i might as well check it before i even pull the flywheel, it its in spec i can recheck without new seal,
re-install seal and flywheel and the double check again , correct? lets hope its all still good i am hoping for just a seal replacment. Like you my motor running good. these are new AA head casings with brand new br seats, sterlite valves and new porsche guides with solid spacers etc. 2056 all new KB pistons hastings rings new cylinders etc. - anyway iver been watching and reading your postings . and re-reading since i will also be putting back together the original motor for a stock numbers matching correct build , thats for later. Oh the guy that assembled my short block said wht i have the other OEM heads done by another machine shop the guidse were off some wer too tight and some were too loose and that shjop(eagle machine in atlanta) said they were sourced from Porsche. My new guy made sure the new guides were perfect before installing them both on my old original rebuilt heads and these new AA casting heads on the 2056.

PHil- what is hte proper end play i am looking for for the crankshaft end play?
