That's Audi baby.... 155k on itand still like brand new

Thanks auditech79

So the question is, what is the easiest way to get rings replaced ?

 

The rings? Well if you still wanted to replace the rings i would do it when your building the engine, you gotta pull the pistons out no matter how you look at it.
But its not really needed, if they were shot when you did your compression test you would see the gauge go down slowly.

 

I kept the pressure about a minute on every piston. did not see any pressure loose or hear any sound.

If it is safe,then I will not worry about it then.

 

Yep, just make sure your oil catch can is clean, and if you have a pcv valve change it and clean the crankcase lines maybe by using some seafoam in the oil

 

Let me tell you it was pita wihout taking out the intake mani. I really want to kill the people who design this. [:@]

PCV hose was broken. that's why oil was all over the place behind the intake manifold. I took everthing out



This is breater assemply or whatever it is. I wonder what really inside or where is this connect to (inside) ?

I think I will relocate my oil catch can and eleminate the pcv valve and do all new custom stuff.

I wonder can I drive mu car wihtout all these hoses ? I do not have any hose attached on that thing on the picture

 

Yeah that big elbow under the intake manifold falls apart after about 100k, its a mandatory replacment item on a sludge repair as well.
You have to have the crankcase sealed on audi engines especially that hose which is huge.
If anything, fabricate a plug for it and use the factory holding clip to hold the plug in.

 

What I want to do is;

Breater on engine (what is the actual name of this part, I'll look at ecs)> Oil catch can > intake manifold

I will eleminate the pcv valfe. what do you think?

 

That works fine on your engine, it would be cleaner as well, less chance of clogging up the system.
The down side is you would get a little bit of an oil smell after running for a while but thats acceptable.
Those of you with a 2.0T do not install a breather! The 2.0T engine is built so tight it will even miss-fire with just the oil cap off. 1.8T engines will work ok the engine management can compensate.

 

what accullat that breater do auditech79? do you know ? why there is air/oil mix coming from there? where is it come from? is it somewhere close to the oil pan or what? I really could not think where it is connected to
