AID! PEUGEOT 505 '84 NAFTA

Well guys I go to tell you what happened to my Peugeot 505 '84 Naftero (XN1 engine).
It turns out that I made a new engine with a set and everything. Also cover and oil pump. I armo and find that water passes to the oil. I check the torque of the lid and I find that I was stolen 3 threads of the block. I do the inserts and when I start the perfect start. I'm going to accent on a route about 800 km and when I come back in the return oil. I leave it with common water for a month to oxide and show me where you lose observe a shirt that leaked.
I go back to the rectifier I have height to the shirts, the bruñen, flat block and lid control, armo and when I start it, back water in the oil!

Every time the lid armes it was with new screws and new together, with the angular troca and everything.

I really don't know what else to do. It is the first time that an engine gives me so much work and unfortunately it is not the only thing that has happened to me with the car since then.

What can be? What can I do? (I have even considered the option to set it on fire or sell it in parts) This afternoon I will do a homemade hydraulic test with the armed engine to see if I find the loss, but it would be good if someone happened to him something similar or sees something that has not planned tells me.

THANK YOU SO MUCH

Look that the water fuse plug that is behind the water bommba is punctured

I'm going to look. When I did the lid, I didn't have the plug so I welded it just like the two brass caps of the back of the lid. Many grains.

Hello fikate when you take the lid if one of the shirts has not dropped when the lid tightens, the cause is that when placing the shirt you may have run an orring or the copper ring that wears some models you lack glue

I am going to look at one. Anyway, that was the problem I had before, so it would be a very bad milk that happened to me again.
A HUG. THANK YOU
