I can't help ya on the cover, For Sale section maybe?

I guess the rest of the valvetrain/engine survived?

i dont know about the valvetrain. the engine still cranks, so im hoping and praying it didn't bend anything!!!!!!!

Well good luck and it looks like you need to add some stuff to your "to do" list in your sig!

what timing chain should i go with. i dont want the double roller, cuz i still need my water pump drive.

This would be a good time to eliminate the water pump drive and go with an electric water pump.

That is nuts!
I have never seen that happen before.

luckily the guy who built my engine is a decent man, and he is sending me a new timing cover, gasket set, and timing set overnighted for free. Why cant we have more customer service like that?????????

oh, and I just got done checking the valves, and surprisingly, there isnt a scratch on em!!!!!!!!!!!

Did you pull the heads?

If not, how do you know the valves are good?

I have seen this 'type' of thing on LT1s and those kind of failures, if they happen while the engine is above idle, almost 100% of the time = broken valvetrain or even cracked pistons/bent rods/etc... Hell, one time the cam was broken.

Good luck on that one, but honestly, the motor requires a teardown if it was running when it happened...

Now, if it happened on startup, then it possibly could have basically stopped dead without damage...

Also, was this a stroker motor or a 350?

yeah, i pulled the heads off

Damn man. Thats the first time I saw that. What were you doing when it let go?

Your post said something about doing injectors, and a couple of other things. Any chance you had an injector leak "big time" and fill a cylinder with fuel, causing the engine to "hydraulic", causing the gear to break?

Wish I could say the same about my valves. This happend two years ago, I bent every exhaust valve. The valves looked fine, but since I had several bent pushrods I sent them in and come to find out I bent every exhaust valve.

These are Melling stock replacement Timing gears with 500 miles on them. If you go with a cloyes stock replacement it is the solid cam gear. Thats what I ended up doing.

That's the kind of damage I was expecting.
OP, investigate thoroughly, no sense in doing another tear down later. If you truly have no damage, buy a lotto ticket!

hah I assume you put it in quotes because you weren't sure. If that's the case, what you wanted was Hydrolock. You weren't far off with Hydraulic though, you just were missing "lock"; however, it also stands for Hydrostatic Lock. Though I'm not sure if an injector could dump that much fuel into the cyl in the incredibly short time period between the cyl firing and the injector opening back up. That's assuming it happened while running, but if not then it being H-locked during initial cranking could be a good possibility.


I can only hope I never have that kind of problem on a motor that's got quite a bit of money wrapped up into it. I never tore into my 91's TPI after it went **** up, but she grenaded good, whatever the cause! lol Poor thing would only turn backwards a bit and stop when it got to the same point.

well I spoke too soon. pulled the headsand inspected them closer(i was in a rush earlier cuz I had to go to work) and found 2 bent pushrods. they aren't as bad as 355z28's, but still bent none the less.

other than that, it survived.

I was racing a h/c/i ls1. I was almost gonna shift to 4th when it let go.

If you have pushrod damage, then you better have the heads disassembled and looked at. You can't eyeball a slightly bent valve stem.

+1. Drop the pan and inspect there too.
