I am pretty sure that most of us, who work on cars have that itch inside that prompts us to complete the project as soon as we can :)
I took a day off to finish buttoning everything up.
Note to myself and others. If you end up needing to replace the engine in Jetta or a Golf or a Passat - remove it together with the transmission. It will make project so much easier. Especially mating transmission to the engine. I used hot glue to temporarily attach the nut to a socket for installation. It is really easy to drop the nut into bell housing. Ask me how I know :)
It looked like all spark plugs and coils were replaced on the old engine and I have transferred them over to the replacement engine.
You know that feeling when you have everything connected and can turn the ignition key to start it for the first time after engine work... I turned the key, and... start for 1 second and stall.
Long story short - I have not connected fuel ramp to a correct port. It took hours of attempts, troubleshooting but finally it started and was revving up to 6k rpm and staying there. I have installed "old" intake manifold, "old" fuel injectors, "old" throttle body. Issue was still there. Asked a friend to help and we rolled it out to the driveway and left it there for a few hours. To my big surprise after it sat for a few hours it started as if nothing is wrong!!! Till this day I do not know what was the issue.
Finished putting her back together and took her for a first spin! It drove really good. I was happy with the progress.
Took it for an hour ride to set all emissions monitors into ready state. After the ride all, but O2, cat and EVAP were set. My daughter asked for her first ride lesson on a new car. One hour later - all monitors were "ready".
Next day it passed smog with flying colors!
Now it was time to address some issues.
1) AC and heater fan was working only at setting 4. It is a known issue and the fix is fairly simple - remove passenger foot well cover and replace the blower motor resistor 1K0959263A. It was also a good time to replace cabin air filter. Charged AC system with refrigerant and car got the AC back.
2) During installation motor got fresh oil Castrol 5w-40, new oil and air filter. I have also replaced the coolant expansion tank.
3) Replaced read brake pads. Decided on Duralast DG1456 ceramic.
I have discovered that VAG cars are little bit like lego - you can modify the car to your hearts desire. A lot of parts or systems from newer/better equipped cars can be retrofitted. I started making a list of "needed mods".
A) Replace radio with one that supports rear view camera
B) Replace simple steering wheel with multifunction one
C) Replace dash with MFA+
D) Additional keys, since car was bought with only one key
