cam install gone WRONG!!!

Someone should have slapped him and said "LISTEN DAMIT YOU HAVE NO IDEA WHAT YOU ARE DOING" and if that doesnt work, pull out your gun and yell out "DROP THE CAMS AND STEP AWAY"
Tell him to get a profesional to do it or assist him next time his has a bone head idea like that.

I would just laugh at him and tell him to take it to some professionals before he makes it worse. If possible to make it worse.

That whole scene would be a painful thing to witness. I'm curious, ask him why he did it this way. And why would he risk destroying his car. What year is this Mustang. If it was a 99 or '00, the cam gears are press on verse the bolt on type.

I like the gun comment, drop the cams and step away from the car. LOL.

Dude it really sounds like your buddy did not know what he was getting himself into. Anyone with little experience would know not to tackle a camswap on a mod motor because it can turn into your biggest nightmare if it goes wrong. You can do it on romeo motors provided that you have the chain retaining tool but a windsor motor has pressed on gears so I would reccomend taking the timing cover off.
For someone with a little experience on OHC motors you could just paint mark the gears to the chain and make sure you install it the way it came off. If you have a pre 01 car then you must retime the motor after pressing on gears to new cam and thats that. There is no intall and go. Retiming the engine is not that hard. The inexperienced could do a little research and accomplish that no problem. I know its been said in this thread already but the best advice anyone can give you is to ALWAYS hand turn the motor with a breaker bar. Bending valves just digs you into a deeper hole, take it from someone who has done it, IT SUCKS.

Ayone with a little mechanical knowledge can do it provided they do a little research and make a good decision whether they want to or not but if I were you I would tell your buddy that he is in worse than he could of been if he would have took his time. Now you either pull the motor and take off the heads to see what valves are destroyed or but a new engine. Either way good luck.

hes just has to start from scratch. he needs the holding tools for the cams and the crack shaft alighnment tool. and take the front cover off and do it right. and you might want to tell him there is a TORQUE spec for the cam towers!!!!!! timing the 4.6 isnt to difficult but you need patience. if not he shouldn't being doing this mod. cuase one tooth can mean the difference from running or total engine destruction. i just hope he hasnt hurt it to bad but it sounds like he might have. O and thank him for a good luagh I love laughing about someone else's stupidity.

yeah he has too start all over

step 1 remove cyl heads...

step 2 walk with cyl heads too dumpster.. insert heads in dumpster

step 3 walk to same dumpster with cams if removed and insert into dumpster...

step 4 if no piston damage was done then find somebody with a brain..

step 5 the person with brain can take it from here....

Cam Caps being too tight will cause them to break from over tightening or Threads on bolts to strip in alluminum head before it would apply near enough pressure to keep a cam from rotating. Sorry man but your buddy most likely bent a valve or 2 or 3 or more. Thats the (my engine wont turn over) problem and it happens. Hopefully the toyota dealer has a better tech than your buddy and can clean up his mess without too much money or else a new set of heads and possibly a bottom end will be on his **** to buy soon list.

yeah, .... he is deffinitely feeling the pain... LOL.. but i cant help to laugh. i just wish i had a camera handy! lol! i mean, it looked like a freakin cartoon or somthing, cause he was working sooo fast and when somthing would not work he would ask for a bigger wrench, and a bigger hammer.

why would the heads be destroyed possibly? the cam towers being over tightened??

agreed


if he wants to pay someone to do it.............pay for my gas & some install change & i'd be up to helping him

thanks for all the input guys. i have not talked to him since the "incedent" but i do know that it is sitting in front of the toyota placed and has not moved a bit. lol. i have a quick couple questions- first, how bad is it to NOT change the valve springs, i know with my motor that it is VERY bad to not change the valvesprings when changing to a larger cam. (ls1) and how bad is it not to change the timing chain? and just think- this guy just put a nitrous kit on his car last week.... lol lol... i bet its put in REALLY good.. i know he will not take it to a professional, and i know that he will not do it right the second time. he still thinks that he put the caps on too tight and that is holding the cam, hence keeping the motor from turning. what yall think???

edit... the car is a 97 5speed

thanx mike

Hey da zman, no offense to you but as far as your friend goes, GOD SHOULD'T LET SOME PEOPLE(his parents) REPRODUCE! That is the first thing to note here. My 98 only has 54,000mi on it and I put on less than 1500 a year. It ran perfectly in every respect before my cam install, so IMO tearing it down all the way was a waste of time. I used the Andersen tool. I READ THE DIRECTIONS, and after studying how and why it works, I used it. The install went off without a hitch. And, with only .495 lift I didn't need springs either. The stock springs are good to .525 or so. Now, if this 97gt has many more miles on it, like 60 +, then he probably should have tore it down all the way and replaced chains, springs, etc. The cam retaining plates only require like 108 inch pounds of torque so if he used an air ratchet the saddles are probably stripped now anyway. He had to wedge the sprockets back onto the cam nose and pry the rear of the cam down because the chain tensioners totally unloaded, and like said earlier, probably skipped teeth. Unbelievable.

I think this guy deserves one of the Toyotas sittin around that shop.
