Bought this '96 GTI from a guy that bought from another and did not fix, just sold, so I have no history on this engine at all. When I got it, I could not turn the crank at all, assumed the engine was froze up. Later I was able to turn completely over, then weeks later it fouled internally and could only turn it 1/4 turn of crank rotation.
This past week started to dig in and removed the intake manifold (which had been sitting with no carbs on it, open to the elements for I have no idea how long, so assume some kind of debris got in). When I pulled the manifold, no sign of contamination or debris. Now could turn engine almost 360, full rotation, but stopped just short. Tonight, in prep for tear down, I pulled the exhaust manifold and find I can rotate the engine 360 without issue, but as you can see from pics below, there was in fact something fouling the plate and scoring of the intake manifold surface. No noticeable debris was found in the area where I pulled the exhaust manifold off, so i still have no idea what was fouling, stopping rotation and scoring the surfaces.
Couple of questions;
1 - If debris fell into the crankcase through the intake when the engine sat and traveled down into the crankcase, is there room under the crank for any to lie (hardware, etc. under the crank) or is it a very tight area and most likely whatever scored the plate and intake fell outside the engine? What are the chnaces of something still inside the crankcase?
2 - Is the scoring of the intake surface and / or plate a concern if i reassemble or rebuild the engine and use it (which I plan to do)?
3 - Personal opinions on rebuilding this engine or putting it back together and run with it as is?
Thanks
