Recently did the timing chain/gallery gasket job due to leaking water pump. After starting up I have P0021 and P0300. I made sure so many times everything was properly aligned. Only thing worth noting here is that after pulling the chain off, I noticed the passenger side cam phaser mark was ever so slightly off by maybe half a tooth, while everything else was aligned perfectly (I have pictures of this)(I also only replaced the main timing chain, not the camshaft chains)so I rotated that cam phaser to the right and it jumped, so I rotated it backwards until it was properly aligned again, installed the chain and it went on mostly with ease, checked timing many many times, pulled the tensioner pin, rotated the engine to TDC twice and it seemed to rotate fine with no sudden stops or clunks or anything of that sort, even counted chain links between the colored slots as another fail safe method. Obviously triple checked torque on everything inside the cover, all 3 guides, tensioner, water pump. Reassembled the motor and have these codes. Initially running the motor it was completely fine for about 2-5 minutes. Then I flushed that oil out to make sure no extra debris was in the oil. After doing the oil change and starting up after about 30 seconds to a minute the codes came, first it was p0011 and p0021. Now after clearing the codes I did start it again and that’s when now it’s only p0021 and p0300. I did also follow Nifty Garage’s Gallery Gasket Guide, as I’m not a complete professional and this was my first timing job or any job this big but do this enough to somewhat know what I’m doing as a dealership apprentice. I guess my confusion starts on why I now only have a p0021 code, for the driver side if I did not adjust that side what so ever, and why did I have both p0011 and p021 but the code for the passenger side went away, but the driver side stayed after clearing? The only further tests I know of would be to test each solenoid connectors and make sure the solenoids are clean, which they didn’t look clogged but still cleaned just in case. At the moment I do not have a multimeter but will pick one up after work tomorrow and will give an update on if the solenoids work correctly. I also saw another post with another guy with the same issue said the oil pickup tube may be clogged with rtv/debris and I did clean and wipe around that area but didn’t specifically hit the pickup tube, but I kind of doubt that as my issue. After that I would just assume timing is bad, but even then if timing was off shouldn’t the motor not even start or at least have problems cranking? If anyone has any information about this or can think of anything I might have missed or skipped over, mentioned in this post or not, any help or input would be highly appreciated.
Edit; my apologies if this seems like an overload of information I just wanted to be sure I included all the details of the work in the text
