Not F-body related, this was my Conquest... The winter car.
I'm driving, I hear "tink tink tink." Car loses power, I pull over and shut it down. WTF? I tell my friend to crank it so I can hear where the tink is coming from. Initially I thought it was the timing cover. So he cranks it a little at a time. POP, valve cover explodes, dipstick flies off, and the breather on the back of the VC blows off and down the street. WOW, it was loud. So We get it to his garage and pull it apart. Can you say crazy crankcase pressure?
So I inspect the head over. The intake valve on the #4 piston is GONE.
So I pull the head because I know if I don't I won't be able to sleep without knowing what has happened to my cylinders and pistons. Well, it wasn't what I wanted to see. That's a picture of my $500 JE Forged Pistons. Nice eh?
Metal shavings in every cylinder. From what I can see the two middle cylinders are fine, nice cross hatch in each one. #4... Pic speaks for itself. Can't express how ticked I am about this.
Finally, the damage to my 400 dollar marnal, w/ marnal valves, hd springs, new lifters, etc... 5000 miles total on everything. I wonder if it's the machine shops fault, maybe used old valve retaining clips to hold them down, I don't know. I had them do my head before, then I bought some HD valve springs and I had them throw 'em on. Everything on that head was new. New oversized Marnal valves, HD valve springs, new lifters, ARP head studs, supposedly new valve seals and retaining clips, etc... Only thing I reused was the rocker shafts. Hell, I even have new roller rockers on there. Here is what's left of my head now. The valve bent inside of it's hole, can't even get it out. Chewed up the head around it.
Going to pull the engine tomorrow. Work and time isn't an issue, I have this car down to a science, I can have it out in about an hour or so, rip it down to bare block, etc... I'm just not made of money. Gonna need a new piston for sure, get in there and check out the rest of the pistons and cylinders. Cross hatch might be in order, head gasket, etc.... Bearings are def. gonna need a lookover, maybe R&R etc, if the metal shavings did a lotta damage....
I am so upset about this, I had to vent... I think the machine shop did a poor job of putting my valves and valve springs in, that's why this happened. My timing was set perfect, right where it should be, car was running fine... Driving down the street going 25 in third gear when it "tinked." I was going to let that guy do my Camaro work, too. I'm def. going to reconsider that course of action.
I'm not going to call them complaining, that won't do me any good. Live and learn.
Camaro is out and in front of the house, sittin in slush. Such a sad sight. He hasn't seen snow all year.
So how was everyone elses day?
