Fellow DSMers,
first of all let me start by thanking all the ones that tried to help me a couple of months ago when I first posted about my problem. Click here to see the post I am referring to.

Well, the car was parked for a couple of weeks because I had some issues while installing my FMIC (long story) but here's what solved my problem:

As you can see from the original post I was desperate, and I tried nearly everything without success. My last chance was the Head Gasket, so one morning I meet my friends in my house and we start taking apart the car ready to change the Head Gasket, when my good friend Carlos tells me that the timing was "slightly" off. So, we check the compression and I had something like 220, 230 on some pistons, and less then 100 on the other... (sorry for not being accurate, but we did it a few weeks ago and I don't recall very well).

So, we try by re-doing the timing correctly, and after checking the compression once again (moreless 130 across the board) I park the car and start what will turn into a 2-3 week long FMIC install.

Well, I finished installing the FMIC a few days ago, and in the past week I've been tuning the baby, obviously flooring her hard.

No more leaks. It was the timing.

I am so glad, thank God! That thing was becoming a nightmare, it was like a desease for me.

So, the purpose of this thread is to let you all know what was causing the problem, to thank you guys for all the help, and hoping that this will save quite some time to somebody that might run into the same problem as I did.

Regards,

Walter
 
Timing = Boost Leak

me either!!
Well, if you think about it could happen. Let's say you set the engine a TDC but you timing is off a bit. Depending on which direction it is off, you could have an exhaust valve or two barely open when the intake valves are open and leak pressure through the exhaust when doing your leak test. Now I'm not sure when the engine is actually running the same would happen. Since the turbo forces air into the cylinder you would have a constant supply of air/fuel into that cylinder and leaking out of those out-of-time exhaust valves until they closed completely. You may not get as dense of a charge to that cylinder, resulting in less power on that stroke.

This is all in theory so take it with a gain of salt.

LoL........

ATK.... i believe you mis-read the subject or this post and did not bother to read his initial post. he is saying that he is/was losing coolant under boost.......

i believe you are referring to him doing a compression check on the motor...
 
Adjusting timing should have NO influence on a coolant leak.

No idea what you did...The type of intercooler should not matter as to having a coolant leak or not. If high boost makes a difference, then it probably is a head gasket issue.
