So few months ago put about 3 grand into my gst, evo 16g turbo, act clutch, intercooler, had the head rebuilt and all that good stuff, 2000 miles later my car sounds like a damn soda can full of rocks. my cars knock almost sounds like a diesel but not as good lol im thinking bent valve maybe, i did have a overheating problem recently, where the coolant was just leaking or escaping somwhere, so im trying to figure out if im looking at a head or maybe just a few valves. opinions?

 

Is it more of a ticking?

 

water pump maybe?

 

What are your mods?

 

its kind of a tick but at times more seems like more than a tick, at times it almost seemed like it was keeping my turbo from spooling up and choking my car.


MODS: Evo III 16g, 5zeigen exhaust, cold air intake, greddy type-s bov, composite headgasket, act 6 puck racing clutch, machined and rebuilt head, turbosmartmbc (i hsve it set at about 15psi), all but exhaust and cold air were put in 2000 miles ago.

 

better discription, i took it around the block today, the turbo spools up but the rpms struggle to rise cant get motor above 2grand, the clanking is horrible i almost wonder now it i threw a rod or something

 

drop your oil pan and check it out

 

What are you using for fuel management? What size injectors do you have?
Here's what I see:
- E316G, aftermarket HG, aftermarket clutch, and rebuilt head.
The rest are support, but you don't have fuel components listed, which leads me to believe you had detonation by going lean in a chamber or more. You need to do a compression check.

Your mods make me think the worst since there's no logging or management mentioned. A ping is one thing, clanking is something else.
What was the last thing you did before this happened. My thoughts are that your motor went past 5k with a load on it.
Even 15psi from an E316G at WOT is nothing to scoff at.

 

fuel was stock but i never had any problems with it leaning out it ran solid, i run it hard but the other day i got in it it was a clicking at about 3grand in first thats all i kept an eye on it took it straight home, next day took it around the block and its clanking.

 

how do you know that you werent runnning lean? do you have a wideband in your car by any chance? cuz that's the only way you'll know for sure
