In need of help.

Ok so I bought my 1g turbo talon may 2007. When I bought it I ended up replacing the head which ended up being a bad one so replaced it again and drove it fine the rest of the summer. well then back in october I was driving it and the motor died. It then sat all winter. Well finally got out to check it out, took the valve cover off and found out that all of the rockers on the intake side were off, a few of them were broke but most were just laying there. After cleaning all the pins out and bleeding the lifters I replaced all of the rockers, now the cam lobes are not sitting on all the rockers at once, when you crank it and then stop the cam lobes sit on two of the rockers and if you crank it again it will sit on two different rockers but wont sit on all of them at the same time. Checked timing marks and all is good there but what else could it be?? Any help would be great. Thanks

So you pulled the MPI fuse and cranked it over to prime the oil pump. Are you saying that the rockers are not touching the cam at all?

 

[eagletalon_92]

I have tried this but how long should I crank it for. I didn't want to over do it.

 

[delta448]

Crank until the oil pressure light on the dash goes out.

 

[eagletalon_92]

we i crank it they touch but only two at a time they are never all touching at the same time and then when i stop cranking only two are touching while the exhaust side all the rockers are tight

 

[delta448]

Are the lifters on the intake side fully extended, or can they be pumped up more?

You jumped timing and have bent valves.

 

[eagletalon_92]

My husband was thinking maybe crank walk because we have gone through so many heads. What do you think?

 

[delta448]

No.
Crankwalk does nothing to the head. Besides, you probably have a 6-bolt in your 92.

You're probably going through heads because the t-belt tensioner is bad, or you aren't getting the deck surfaces machined, or you're overheating the engine and you probably aren't maintaining things very rigorously.

When the rockers fall off, that usually means you have a bent valve.

you have bent the valves...Remove the head and check the valve to see if it closes all the way..You can check it by going into a dark room and shine a light onto the top part of the head..if you can see light from the bottom (where the valve seat) then its bent.
