Bent pushrods #6 misfire

[Sean2179]

Let my brother borrow my 06 Lbz and he said it lost power and had a knock. Had him pull over and check with scan tool. Had a turbo code and #6 misfire. Drove it a little more and completely quit. Had shop pull the cable covers and had every intake pushrod bent. Since then I have pulled both heads and front cover. Looks like camshaft dowel is a little bent but didn't know if this little amount would cause so much havoc. Any help is appreciated.

My guess would be what ever keep the intake valves from opening weather it be piston or not is what bent the push rods and then in turn bent the cam alignment pin.

What about the timing gear on the crank? They have been known to slip as well. Is the truck stock?

x2, pull the front cover and look at this.

i would suggest fixing that bent pin before reassembly
