Its official. The 3.5 swap kicked my butt
So, trying to start the car with timing off and not knowing it at the time....bad idea. I was looking at one of the other guys posts here,
and i noticed how his exhaust dowl pin was much longer then mine. I didnt know/realize you needed to swap the 3.0 ones, my mistake. But I am guessing the damage to my exhaust cams are only the tip of the iceburg. I supposed it could of been caused by not having long enough dowl pins in there and it put a ton of stress on the inside of the pin causing the back end to break. But I have a horrible feeling in my gut that with the timing off, valves hit pistons, stoped the cam very forcefully and thats how that happened. This sucks. I am guessing its about time to pray to god my valves/pistons arent destroyed.

Sorry to hear your troubles, I try to remember during situations like this that......it can always be worse.
I'm a little confused here, So your 3.0 exh. cam sprockets weren't centered on the cam dowels?

They were secured, torqued and turned fine by hand. I am actually pretty confused myself. I am not sure if it was from valves/pistons hitting - hopefully not. Or if it was from something different. I was thinking that possibily not having the longer dowl pins in there put to much stress on the inside of the pin somehow making that piece of metal split off,

you didtn realize you had to swap what exactly? the dowel pins?? I got the impression the dowel pins were just there to line everything up and once you bolted on the cam gears it was all secured in place.

actually, one of the cam gears wasnt sitting flush and the dowel pin popped out...i was freaking out..but just kinda tapped it back in there and put it all back together and bolted it together.
mine definently never extended past the gear though, i know that.

ya, i mean there wasnt much for them to sit on but they were on. I am debating, 3.0 cams in there or a lil bit of JB weld haha....the crack/chip doesnt go through the whole piece...I am really not sure if i want to deal with that breaking down the road though, so maybe 3.0 cams

Geez that suck so much! I'm sorry to hear bad news about this swap. Since I'm autotragic, I went 3.0 cams and it's running well. Epecially without the cat-back. hehe! The only pita I have, are these codes:
0403 Throttle Position Sensor
1206 Throttle Position Sensor (Automatic Transmission)
and the lost of tach signal. (rpm stays at zero)

Ya i just need to see if the valves are bent, if they arent all i need is some cams, if they are...cams, probably all exhaust valves, cylinder head bolts and headgaskets. I dont have a cylinder leakdown tester, So i am thinking with the cams out of the engine just hook up a compression tester and jump the starter and I think that would give me a good enough idea about what damage is done there.

If the sprockets were on the dowel pins even a little when the sprockets were tightened, and the links were all lined up (even 1 or 2 teeth off) you wouldn't have bent valves, only if the sprocket was to 'slip' on the cam would you bend valves......
