I just finished putting my e30 back together. I pulled the engine to replace many of the seals and to do a thorough cleaning. Anyways, when I started it back up for the first time it had a rattle that I would say was consistent with an engine that hasn't been ran in 3 months and it went away after 2 or 3 mins.
Next day I started it up and it was there again and then went away. I had put in 20w50 GTX and thinking that maybe its getting a little cool here for that and it's a bit thick. I drained it and put in Liqui Moly 10w40 with the friction additive and it was still there.
Any thoughts? I adjusted the valves when I had the head cleaned to .01 per all the write ups I looked at.
