We had the camshafts set for TDC, and we started out with the pistons =
all in about mid stroke with #1 on its way up. Moving from there to =
TDC, nothing could have interfered. We never took the shafts off the =
1.8 head, so the intake must have been timed right with the exhaust and =
all that sort of thing. =20
We did this without spark plugs, so it isn't at all related to =
compression.=20
The block has new rings and bearings in it, and new front and rear =
seals. So maybe one of those is messed up, but if that were the case it =
would just get stuck here or there, or get jammed up, right? It =
wouldn't make the shaft want to pop from something like 10=B0BTDC to TDC =
practically on its own and rest there, could it? =20
I guess the thing to do would be to tear down the whole thing and =
check it out, but its in the car now. We should have done that as soon =
as we noticed the problem but I guess we weren't in the mood or =
something. =20
Can the oil pump be removed with the engine in the car? I assume so. =
Maybe there is something bizzarre going on between the pump or baffle =
and the crank.=20
Any more ideas???=20

So, you are turning over the motor without the timing belt hooked =
up??? That is suicide man! The 2.0L 16v is an interference engine so =
you HAVE to have the timing belt hooked up to turn it over to TDC unless =
the cams are not installed. There are ways of turning thre crank around =
without hitting valves but it isn't easy. I can't think of anything =
else that would be interferring enough to cause the "popping" feeling =
that you are feeling at TDC than if you are smashing a valve. I hope it =
isn't that, for you sake, but unless something weird is going on with =
the wrist pins/bushings or rod bearings or something along those lines, =
I can't think of anything else that would cause this.

So I was in Ohio helping Josh and Brian with the 2.0l install. =
When putting on the crank pulley we noticed something odd. We held a =
screwdriver in the #1 spark plug hole so we'd know when it was about TDC =
so we would get the pulley on the right way. Here's the problem:
When turning the engine over by hand, the crankshaft sorta "pops" =
into TDC. This is without the camshaft connected to it via the timing =
belt, but it feels just like the way the camshaft pops to rest between =
lobes as you turn it. =20
This happened when assembling the head and junk onto the new =
block. There was no flywheel on it, and no timing belt. It's a 2.0l =
16v, so it's not distributor related either. =20
Any ideas? The engine is in and they would like to start it soon, =
but very nervous about this.
