could this have led to my motor blowing up? and if it did, can someone explain to me how and why this would have caused it to happen? i posted this in the newbie section but havent gotten any responses... maybe this is a better section to ask!

thanks!

 

That is definitely not good man. It seem like the end of that rocker broke off?

 

i have no idea... found this when i pulled the valve cover off after throwing a rod.

 

Check to see if your head has any damage. If not, I would check all the valves, replace either all or that rocker that came off and lifters. There is a good how to guide in evomoto website in case if you don't know. Throwing a rod is bad enough. Adding that piece to the rod throwing, glad you found it out before it gets worse. I'm guessing the rod causes that piece to either broke off or loose.

 

yeh i mean it sounded like i had some lifter tick... but i thought it was a common thing on these cars

 

I'm not sure what could have caused your rocker arm to fall off on it's own. It looks like it's fully intact in the picture. How long were you hearing the ticking noise? Perhaps the lifter collapsed and allowed enough room for the rocker arm to come off. Even that's a long shot, but I really don't see how a rocker arm could fall off. The rocker arm gets sandwiched underneath the camshaft. Pull out that corresponding lifter and see if you can easily push it in and out with your fingers. If you can, the lifter is bad. Did you throw a rod in that same cylinder? Without the valve opening in that cylinder, that could have caused the following damage.

 

i had kelford 272s put in back in July... the lifter tick started about 2 weeks before that... the rocker in the picture wasnt in tact, i just lined it up and tried to put it back on... the one on the left wasnt on at all when i pulled the valve cover... yes i did throw a rod in the same cylinder... could this mean that the head is damaged also?

 

So, what you're saying is the lifter that fell off is broken (bent / cracked)? If so, that would explain why it fell off. I doubt it threw the rod and then caused the lifter to come off. I would say most likely the lifter fell off, and having only one working intake valve on that cylinder caused the damage.

There could be damage to the combustion chamber area of the head. You'll know once you pull the head off.

 

how did your engine give, at wot? how many miles?

 

i pulled through 2nd, and forced 3rd gear when shifting... it didnt want to go into gear and i thought my tranmission was getting notchy, so i forced it, and the second it got into gear i went WOT and it blew

 

The rod coming loose allowed the piston to contact a couple of valves. Are the valves bent? Most likely. Does this have anything to do with the engine blowing? Nope.

 

^this^

Most likely the rocker popped off after the rod was thrown, it doesn't look damaged from the picture but it's hard to tell. A rocker first falling off causing the rod to be thrown seems unlikely. Your valves surely made contact with the piston though and the head will need to be inspected.

I have seen evos/dsms drive around with a rocker popped off for miles and miles, show up on the dyno making very little power up top, only to find a rocker laying in the head. Once the rocker gets put back on, car makes the power it should again.

 

thanks for the info guys... i decided to sell the car as is, i know someone will jump on it with all the mods done to fix it up...
