I got it back on the road yesterday. Cranked and shut off as soon as it fired about four times to get the oil pressure up. Started and let run for about 2 or 3 min. Big lifter/valve train tick on the left/ drivers side of engine... freaked me out a little. Started up again let it run for about a minute, then revel it to about 2k rpm and held it there for about 30 sec. Tick went away - I'm thinking it was just an empty last flyer that had to pump up with oil. I took it out for a 50 mile drive. It ran/runs fantastic, but the CEL came back on🙄☹️. I'm certainly not defeated yet, but I'm not super happy either!
Don't be deterred by the CEl's . After a rebuild it is not unusual to get transient/false codes. Still need to be alert to potentially damaging Cel's for engine temp & oil pressure.
Just keep running the Durametric to look for issues.
The ticking Lifter issue - remember the issue Jake raised about Lifter Carrier wear - discussed in another Thread. Be careful with the oil choice

So on my drive home this morning I had an epiphany! I never cleared the code before I disconnected the battery. Duh... The car is running really well. When I got home and giving it a good wash, I hooked it up to the Durametric. Sure enough, code 1341. Code now cleared... fingers crossed it doesn't come back (didn't have time to check real time stuff yet - have to be somewhere now...maybe be able to put some more miles on tonight - to see if the code comes back.
Obviously you took the motor apart but I wasn't clear as to which part did you replace or repair? Really glad it's running well and hopefully no more CEL.
I was thinking of you yesterday when I was changing my plugs and coil packs and pre-cat O2 sensors. I pulled the bumper, heat shields and mufflers.....that alone was a PITA. Actually, that is the hard part, the rest was easy.
Fingers crossed on the codes.....let us know what your camshaft deviation readings are now, as I recall, one bank was about 8 degrees prior to this.

So, I know it's an awfully long thread...here's a brief synopsis:
The precipitating symptom for all work was a CEL triggered by a 1341 fault code. Because I decided to drop the engine to facilitate removing/replacing the cam covers (to access the vario-cam pads - which I believed at the time were the source of the fault code) I decided to do a bunch of other stuff "while I was in there". I also have come to believe that the engine in my car is a replacement and therefore am unsure of the mileage on it, this also factored into my decision to replace the IMSB with the LNE Solution. The following is a list of parts I replaced.
1 - Vario-Cam chain rails/pads
2 - Vario-Cam chains
3 - LNE IMS Solution (replaced a LNE Classic Dual Row Retrofit which had not failed, but I was unsure of the mileage on it - I think around 40 -50k )
4 - Water pump (Pierburgh) and LNE low temp thermostat
5 - LNE hardened oil pump drive key, new spring
6 - New Clutch/Pressure plate, throwout bearing - Sachs
7 - Manual transmission oil - Liqui-Moly 75/90
8 - Joe Gibbs DT40 oil
9 - Porsche Coolant
10 - New Continental serpentine belt
11 - New Coils (Beru) and Spark Plugs (Bosch)
11 - Misc. coolant hoses (2) clamps, nuts/bolts, gaskets etc. as needed.
12 - 3 new chain tensioners
About $4k in parts... In total, it took me close to 8 weeks of part time work, but in real time I'm thinking it was probably around 40 -50 hrs. If I had to do it again, I could probably do it in 1/2 - 2/3 of that time, but still working carefully/deliberately. It was quite an experience
