My 84 1.6 - Help wont start

[ORCoaster]

8V.  He provided a pic of his flywheel on the first part of the thread.  I think it is a gasser from the degree markings on it.

I second the list of parts places listed by Dakotakid.  I generally pull up all of them and price the competition.  Include shipping and handling to be fair.  Once in a while the sites will drop the shipping if you order something close to 50 bucks.  From what you may be buying that might be an easy do for your order.

We are waiting like kids for Christmas on this one.  What is it going to be?   A messed up valve?  A damaged piston or just an engine out of time?

Keep us up on it.  Thanks

'ay. But what he showed on that flywheel was one of the VW timing lugs. Not where TDC is going to be. Lol I want to see where its TDC mark is.

so people dont get to anxious lol this is def a project for me so its gonna take some time... wish i had a lot more time to just jump into this.  Took a few minutes i had free to see if i could find the TDC marks or anything and i cant... it wont turn that direction

the circled red is what my car looks to be timed too... that is right at the top when it makes the thud and wont turn anymore... it only turns in the direction of the red arrow... i didnt try to turn all the way around because I dont want to cause any damage with any more "thudding" lol


hopefully this week i can pull off the valve cover and start to uncover this mystery

[CRSMP5]

fyi... even the stock 200 or 190mm gasser flywheels 0 same place.. they lack the bolt head by 0 but the area is not drilled out.. but cast... hat s the middle bolt of 3 aka 9 retains.. or 6 bolts retain it if smaller then 210mm...

[atherton213]

got around to taking the valve cover off... from what i can tell its timed upside down...  the nub in the previous pictures ]has the cam looking like this


so my guess that little bit of extra movement to the actual TDC mark will put the cam lock spot flat.   But upside down right? the grove should be level with the edge where the cover goes?

[8v-of-fury]

Cam is 180* out. If of course, your crank is at TDC right now.. IDIOTS who worked on this t hing last I tell yiou.

[ORCoaster]

That cam needs to rotate so that the larger half is at the bottom.  But like the discussion here has been the removal of the head will remove all questions about bent rods, broken or cracked valves and potential piston trouble in the future. 

Now that you have the VC off, drain the coolant and pull the head.

[Jetmugg]

Seriously out of whack.

It's time for a do-over.  Like the others have said, pull the head for starters, but don't buy any parts yet.

It will be much easier to establish TDC with the head removed, also.

The crank rotates twice for each rotation of the cam.  Therefore, when the engine is correctly timed, the crank will be at TDC once while the cam slot is right side up (#1 entering power stroke) and once with the cam slot upside down (#4 about to enter power stroke).  The crank doesn't know the difference and so there is no such thing as the cam being 180° out of time with the crank.  There IS such a thing as the cam being 180° out of time with the pump, tho, as the pump also rotates at 1/2 crank speed and so the pump and cam can be out of phase with each other while each still being correctly timed with the crank...

[CRSMP5]

to me it looks  a tooth  or so off.. its almost on tdc of #4... well piston is.. cam almost..

[libbydiesel]

It's definitely off in the picture but he says that is where the cam is at when he is on top of one of the lugs like in this pic:



The crank needs to be rotated to TDC and then if the cam is directly horizontal, it is correctly timed with the crank, even if it is upside down.

What ORCoaster and Jetmugg said

[atherton213]

Should I drain oil as well as coolant?

[TylerDurden]

You might as well drain the oil... you're gonna want to change it anyway.

[Jetmugg]

I got lost somewhere along the line with respect to the photos of TDC and the cam position. 

I thought that the photo of the back of the cam was when the #1 piston was at TDC (on either stroke).

The first step has to be getting the engine to TDC on the #1 piston, on the compression stroke.  If something won't allow that to happen, then the question of "why" absolutely has to be figured out before proceeding.
