The old blue rebuild (1983 1.6 TD)

Here is the video on youtube of the lifter ticking. You cant hear it very well until i get out of the car. The car is at running temp.

Dankmiester, have they put in electricity to the houses in Mocksville yet?? Just kidding, a little Wake Forest humor 

Anyway, here is an idle stop from NAPA, it is from a 1986 GMC pickup. I think it is kind of pricey new, and you should be able to find one at a bone yard much cheaper. The thing to remember is that these only come on carburated engines, if it is fuel injected it will not have one because the idle is controlled by the IAC valve.

I actually bought one from VW for 89 Bannanas, I know crazy, but its how I roll. A lot of A1 & A2 owners complain about the a/c not being cold at idle, a lot of times the idle compensator/stop is disconnected or broken, so you turn the A/C on the idle drops, the compressor is not turning at optimal speed and as the folks from Kay Beck Quack say "Wah Lah", the A/C cools poorly at idle.

You definitely have a tickopalooza going on there.
Have you tried running the valves with a go no go feeler gauge?
Did you set the valves according to the manual, I think you are supposed to rotate the engine to X point and set valve x,x,x, and x. Then rotate again and set the rest?

Sometimes the heel of the cam is not the lowest part of the cam lobe. In the early 80's we had trouble setting valves in sentras because the lowest part of the cam was just past the heel of the lobe. You also may have some funky wear in that lobe, and that is cauing the tick. Try moving the engine a few degrees past the point were you are setting the clearance now, and see if you find more clearance in one or more lobes.

Haha your soo funny! But anyways thanks for the link that is exactly what i need that would be awesome to find in the junk yard.

But on the tick subject i didnt set the clearance, my machinest did to the spec. i told him to. Per Bentley
And he is one good machinest, slow as hell tho. will a tick like that hurt anything if i let it go? Im hoping that once i switch to full  synthetic oil it will calm down alot. or quit. Ive heard of peoples engines doing that when they added synthetic oil.

Im probably going to switch at around 4-5000Miles

Hey D, you are right, switching to Synthetic may help the tick. As far as damage not much of a chance if the valves are too loose, but if they are too tight, especially the exhaust valves, they will not sit on the seats long enough to get rid of their heat and can burn, it can also get the exhaust manifold to glow red at idle on a gasser . Anyway seems like you have done well in your rebuild 

All the best

Thanks Dood! I know they are not to tight! I can spin the lifter when the top of the lobe is not down on that valve. So ill just wait to switch to synthetic i guessss....
