need help, major issues

[cabot2g]

My son just bought a 99 gst and on his way home with the car it went out on him... its blown. for what ever reason it had extreme cank case pressure. it blew a coolent line, the balance shaft plug, and the head gasket.

Im not a noob as far as engines but I am when it comes to DSM and turbos. Who ever had the car before done a poor job under the hood to say the least. Im unsure what all has been done and what hasnt been done. Its such a hack job I dont trust anything thats under the hood right now. I found two lag bolts in the exaust manifold where the threads was stripped. A board was used as a bracket for the intercooler, there are wires added and switches I havent even started to trace back. Billet pullies and adjustable timing sprokets are installed. A td05-16g turbo is installed, bov doesnt vent to the intake.

I just decided we would be better with a fresh block. So we got a fresh block on the stand build to OEM waiting to go back in but I want to make sure I have the mods figgured out and what we will keep or rework.

attached are a few pics...

Did you go back to your AC when you were done or were you doing a AC delete?

This is going to be a DD car so it needs the AC. In the past if we ever compromised the integrity of the AC we had to replace the condenser and evaporator. Guess it was just to ensure there would be no AC issues from contamination.

I was hoping I didn't have to break the lines loose. There may not be a way around it though.

I replaced my compressor myself 6 months ago, and recharged it myself, and its been working great ever since. I didn't have to even touch the evap or condenser.

If your system was open to the elements for an extended period of time (days, weeks, etc) it may be an issue, but my system was only open for a few hours while i messed with it.

You may want to play on the side of better safe then sorry then I am far from an expert though so take my advice with a grain of salt.

Well it looks like I'm just going to remove the freon from the system and just undo the lines. I'm going to sea the compressor and lines. Will pull a vacuum and keep the vacuum on it awhile before recharging the system.

I have searched the site with no luck finding OEM pulley sizes.

Does anyone have OEM outside diameters for the power steering pump, alternator ...

I measured my OD of the power steering pulley and its 113 mm. Want to know if it is a stock size.

Thanks!
