ok i have an issue that is probably not even an issue, but its in the back of my mind driving me insane and i need reassurance. Back around the 1500 mile mark I had an issue with my coolant system where it was leaking fluid like a mother. I didn't notice until i heard some kind of ticking (either knocking or something in the cooling system) so i looked down at my egt gauge and it was JUST a half a cm away from being in the red, so obviously i pulled over and shut off the car. Well i popped the hood and tried to let it cool, then about 15-20 minutes later after calling a tow truck i tried to start the car up for a minute cause i thought it would be cool enough to idle (i knew it was risky, but it was like 10 degrees out and i was wearing a t-shirt so i needed to warm up real quick). well when i started it up the revs just bounced around way under idle bogging like crazy and it sounded like excessive knocking in every cylidner so i shut it off after about 2 seconds maybe less. Well the tow truck showed up and everything was fixed and it has been running strong since then. I now have just over 6,000 miles and i am planning on going turbo this summer. Well i didn't even think about it until now, but do you think there could have been any damage to the internals (bearings or pistons most likely) from that night that would not have surfaced yet? Do you think it would be safe to go forced induction now and not worry about damage from that night. I would think any damage would have surfaced by now because i've put almost 5,000 miles on it since then, but i am now insane guru. I know my stuff, but i don't have neaerly as much experience as some of you like the certified techs and what not. Input is greatly appreciated guys.

 

If the engine hasn't shown any problems yet it's likely it won't now.
Overheating an engine with aluminum heads will usually cause problems with warping the heads rather than bearing problems.Don't get me wrong,bearings can be eaten by low oil pressure but warped heads are usually the first thing to show up.
