#309355 Update!

Fired the car up this morning. ran super well... ideled at about 1500 rpms. :shock: then I went to drive it real quick, made it out of the parking lot, and then heard a clank, car shut off. so I coasted back into the parking lot in Nutral. tried to fire it up again and nothing.

Gonna start pulling her apart again, and see what is goin on... Sucks that this happened!

Really hoping I didnt break a piston and its just a bent valve, gonna get valves, spring and retainers.... take it to a machine shop. have them check the whole thing out again. and see what will happen then. in the mean time Ill also need to find a GSR Exhaust manifold for my set up. :/

#309356 If it is a bent valve, just know that once it is replaced your car will be running perfectly. :thumb:

#309362 Thanks man!

I love this fourm!

So looking like Ill be dropping right about a 1G into the head for a rebuild.

Got off the phone with NAPA, They said about $100 to take the valevs out, and put new ones in with springs and retainers.

So far What I have on my order list is:
16 BC Valves.
BC Springs and Retainers
Gates Timing Belt
Golden Eagle 84MM Head Gasket

Plus Ill have to spend another $40 on oil. I have plenty of Coolant here.
Gonna try to tear it apart tonnight to see where I stand with this whole thing.
If The Pistons are damaged I might have to throw in my B20Z in.
Really hoping there is no other damage to anything. if there is... I might cry.

Also Have to figure out my Throttle Cable issue.

Would a bad valve cause the car to not idel on its own, and make me have to hold down the gas?

#309369 it really all depends on how many valves are bent, if you have a few valves bent it wont turn on at all.

#309414 So youre ordering all this stuff and youre not 100% sure its bent valves?

#309488 Well, pulled the head last night and it is not good.
both intake valves are broken on cylinder one, plug was snapped off.
#1 Piston dead. completly ate up.
The Cylinder walls are still good! IDK how that happened, must be cuz I turned the car off right as it happened.

Head is destroyed. when the valves broke it completly destroyed the valve seals. the whole combustion chamber is destroyed. about a 1/4in dents in it. really really bad damage...

Metal shavings went everywhere. through the intake... nothing thankfully went into the exhaust and didnt do any damage there.

So Gonna order some Wisco Pistons, Eagle rods, ACL Bearings. have to order a brand new GSR head. :x

This sucks that this happened. im kinda pissed at my self.

but ill have a much safer car now.
