Gase recirculation problem makes empty ...

Estimated, I tell you my problem, I have a datsun 160j 1980 (engine L16, the strange thing is that I recently adjusted it, I changed everything that occurred to me, and from nowhere I put my finger in the hose that comes out of the valve cover and instead of blowing empty ... it is something that I had never seen, if Algiuen has some data that could serve me I would appreciate it, as well as the diagram of the Motor distribution, since the only thing that occurs to me is that this bad tuning the chain (a little backward camshaft) since for the engine to match in idle you have to advance the progress too much ... thank you already for reading and comment

In the datsum it is normal that pacifier for the valve vent because it is the PCV valve disconnects and tapome the same to see if this is the case lucky and ready

Dear I appreciate your time ... The issue is that it is only the hose, it does not carry v/v pcv, it is supposed to be a positive recirculation ... Thank you, and I hope more comments, hopefully someone who has happened to you ... greetings.

Well, I think that you should verify if the cams are left in the overlap's position I think that the caliber of vavula is ten thousandths of struggled to adm and Esc first vrifies that the cams are not larger than others than others and if the tree is original and if you do not have to clocate the time the second position only in the cylinder head or connect the cables from behind. THE DITRIBUTION IS AREAVEZ

Estimated, thanks for your contribution, the regulation of valves is at 0.25 and 0.30 mm edm and esc respectively ... the cams is the original and is like new ...

the distribution, when I disarmed thought that it was badly done and not mark anything, and as I could not find ulgun cylinder 1 in escape) This causes me doubts, since the brands of the cam did not match ... I tell you that the slowdown is irregular, but at high or when driving it is guning ... the other is that when it turns on cold it costs too much to stabilize and fail, until it is a good time until it reaches a normal t °. With the ignition advance over the 30 ° (advanced) the idle is regularized and with the cold engine it is almost no need to take temperature for the engine to work well ,,, the emptiness in the positive recirculation does not vary ... I think that tomorrow I will verify the position of the camshaft ... I think it can be that ...

thanks for its time, and any contribution will be welcome ...
