Hi,

sounds good with your flanges, i really waiting for some news from your engine.

Regarding the headgasket, i don't mean overall bending of the block surface, what i mean is very partial plane holes in some areas.

If i remember correctly, all my headgasket problems occour on cylinder 1 or between cylinder 1 and 2 on the driver side. The last one was broke directly behind the belt tigthener of the timing belt, engine still runs nearly normal (no white smoke, no extra pressure in the cooling system), but makes a noise as the head has had a big hole directly to the precup and there was nothing to see or to locate, because it was behind the tightener.

Best Regards

Hi

a bit off topic.

I have finish my AAZ rebuilt und have to recognice that i have a leakage between colling water and exhaust port from cylinder 1.

Do you or you friends have experience with welding this kind of leackage on IDI cylinderheads.

My m21 head is welded up fully... it was cracked from every place...

good way to weld those is
1. open those cracks fully with grinder
2. then heat up the head
3. weld it
4. heat up again
5. very slow cooling

Hmm I need more info on this.

How hot do you heat the head?
Do you weld it hot?
Do you allow it to cool fully before heating it up again?

I had this idea using a home oven but I had not heard of this technique before. Heating, welding in 10 minute "bursts" to keep the head from cooling too much and putting it back in the oven so each weld is done while the head is hot. Then putting it in the oven and turning the temperature down every hour and allowing it to cool overnight inside the oven, maybe with some bricks inside to retain heat.

If you were in the belief that mb:s, vw:s and bmw:s are only powerful diesels in finland... you were wrong...

Hi,

did i remember correctly, when i say that you have sheduled to make a dyno in oktober?

Best Regards
Alleslowbuged

P.S. I did not found any shop for welding my AAZ cylinderhead, so i have tried to solder the crack. For soldering i have to get a temperature of min. 400°C, but even with preheating to hole cylinderhead up to 280°C and using two propan burner (each with flame temperature of 1900°C) i could not reach necessary temperature. By trying to solder i have open the crack, which is now a hole (appr. 7mm x 5mm).

I now look for a "new" AAZ cylinderhead, if any wand to sell one for a reasonable price please contact me.

Here is the crack:

Here is preheating (4,5 kW)

Here is the hole:

Hi,

just as short notice, i have soldered the hole in the exhaust port, and restart the engine yesterday. It seems to be sealed.

Best regards

So how did you fix it? That look like a difficult problem to solve, I would like to know how to deal with stuff like that. Thanks.

Alleslowbuged · Post by **Alleslowbuged** » Nov 30, 2011 4:53 PM

Hi,

it is a bit to early, to realy say that it is fixed, but there was no leakage during warm up with closed expansion tank.

Here can you find some details from my first try, the second was nearly the same.

It looks that you need more RPM for your engine...

nothing special in here.... due to my new job im starting older projects like my lada vaz 2101 turbo project and soon i will finish my 524td...

btw i work in muscle car performance shop today as mechanic

this sounds like a job wich can make fun...

The advanced timing of my AAZ pump is not working properly, i gets only a maximum internal pressure of 6,0 bar, so the advanced timing is just working proper up to ~3400 rpm. And yes more rpm would be good, can you suggest a "safe" redline for AAZ engines?

damn my friend is offline... he know how much aaz can take rpm
he has 200kw 1.9td vento...

and yes my job doesnt feel like a job... it is like a hobby
