I don't get what you have done here?

You had a working vehicle and you wanted to replace the timing belt?

If you put the cam lock in before taking the old belt off that should have shown you where tdc was at with the flywheel mark.

You make it sound like you don't even know what parts are on the car so all bets are off.

But all the 1.6 diesel I have had have flywheels marked like the picture you just linked to, and you can easily see them with the tranny plug taken out.

Sounds like you let somebody else touch it and have been turning it over this whole time? Did it turn smoothly? You could have had a really bad day and things rammed into each other, or you can be a little off the marks and it won't hit.

If you have already been rotating it, put the cam lock in and take a picture of the tdc mark. you might only need to take the belt off at that point to move the crank a bit and get back on track.

on my flywheels there is a solid raised piece a bit away from the tdc mark which might confuse somebody without a manual.

Looking at the first picture and the second picture, is it correct that you found 2 timing marks on the flywheel? Do you have a gasser flywheel? They interchange with the diesel ones but the timing marks may not be in the right spot, so you may have to improvise. I have a larger 210 mm flywheel from a 16 valve gas engine and there are 2 marks, a small one which is actual TDC and a large one which is where the spark is supposed to be timed for the gas engine, the latter will not work right timing a diesel. It's normal for the pump to feel like it's spring loaded... because it is, you have the heavy plunger return springs in there, but the pump pulley should not move once the belt is on, any slack in the belt should be at the tensioned (watch that the flywheel doesn't move on you) when you put tension back to the belt. If you think things are not timed correctly you should take it all back apart and make sure it's assembled with all the components at their TDC positions, and you still might want to check the pump timing to be sure.

I have been rotating it and only seem to have a springing type of tension if any. I have no idea what flywheel is on this vehicle. And when I had the oil pan off rotated the engine to the two smaller diamonds and it appeared the crank was at tdc. After looking at it now I figured one mark was tdc compression and the other was tdc exhaust. I also assume the valves are fine because when I rotate the engine i hear gas escaping when the intake valves open.
The engine has been timed and I have been rotating it. All parts are on except starter and battery.
Most likely wasting time at work.

The crank is in the exact same position for TDC for compression and TDC for exhaust.

I have no idea why I said that. I'm at work I knew that just being dumb and distracted by customers

I'll put some corks or something in it and see if all 4 pop boss did that with a Ferrari flat 12

PO headaches. I know that the po replaced the tranny because a tire kicker blew the original up. He may have replaced the flywheel at that time. When I had the oil pan off and the engine at what I believed at tdc it was closest to the two notches not the one and the fact if you look at the first two photos I posted. the crankshaft looks to be close to tdc at the very least. So from that I believe the real tdc mark is incorrect.

I was just reviewing the pictures more closely and it appears the two notches which I have not seen in any other picture online or such look to be added on by hand. If you look at them the edges on the larger notch seems to be pushed out not cut like the single larger mark.

Most likely wasting time at work.

I wonder if the PO didn't roll the engine up to TDC mark it and then roll it back the other way to TDC and marked it again. So that he would use the middle and call it good. Seems to me someone here mentioned a method similar to that for finding TDC.

It was previously owned by a nonvw diesel entusiast who was a really nice guy gave me extra set of injectors. I emailed him to see if he will respond.

He didn't give me a Bentley so I assume he did his engine repairs with his common sense and the help of a instructor at a local college and that's why the real mark didn't line up because he didn't realize the gasser and diesel flywheels are different since gasser trannys fit. All I know is I'm going to buy a bare engine and build it up in my spare time after I get this guy running.

Most likely wasting time at work.

icyhotpatch · « **Reply #53 on:** June 24, 2014, 03:03:18 pm »

Turned over engine trying to bleed out injector lines no weird noises.

however, I have a big plug and two other wires missing labels oil must have made labels not stick. I will take a pic of the two for you all to see. The two wires come off the coolant sending unit or what have you and have white plastic pieces one end is male the other female. The other is large and has like 6 female connection inside and a black rubber weather protection.

Most likely wasting time at work.

Its sputtering a little but not starting

Most likely wasting time at work.

The first one is for the transmission, it will plug into the reverse light switch. The second looks like a long wire with black tape on it...no clue. It also looks like you have it labeled, if I had to guess it looks like the one that goes to the solenoid

icyhotpatch · « **Reply #57 on:** June 24, 2014, 04:53:14 pm »

The second one comes from where the coolant leaves the top of the engine there are two plugs and I have them labeled so I know which ends go with each other the original label is missing.

Most likely wasting time at work.

I have diesel exhaust but no running engine

Take a better picture and maybe I could see.

Pull start as usually it kills a starter by the time you actually get it going the first round.
