HAHA! That reminds me, I was trying to figure out if I could still run the car without the turbo and just be NA but its a logistical nightmare...THATS how much I miss driving my car LMAO its been almost two weeks!

 

lmao that sucks, i can still drive my car, but i hate it lol

 

Yeah bro, sure does! Hope you get her fixed up asap

 

so you rev'd to 8000+RPM?

 

I did in my lsj. . I popped lash adjusters mainly.... Btw i was ummmm stock.. Hahahahahaba jk.

 

woah havent been on the site in a while. im actually going with stock valve springs for now, but when they broke i believe i revved to about 9000 rpm haha

 

damn!

i didnt read everything but cft should be able to help you out. there shop is by valencia community college.

 

oh yeah i know cft, im doing the work myself though just need some time

 

any new updates/pics OP?
I'm finding this really informative

 

its been a slow ass process thats starting to annoy me. found out we need to drop the subframe because it is impossible to get to the manifold bolts. so projected time to get the head off is this weekend and then i will order all parts the same day. dont worry, ill keep it updated and im glad ppl are learning from this haha

 

Sorry to hear it's such a pain. Too bad you didn't live closer, I wouldn't mind lending an extra set of hands and opinion this weekend. It'd be a learning experience for myself with getting better knowledge on the LNF.

Good luck and keep us posted!

 

thanks man! its quite a learning experience for me as well but ill make sure that it gets done by me and not some shop

 

Cobalt & Ion ---> ZZ Performance

 

oh trust me ive been browsing on there for a longgg time. after this rebuild i will be ordering some things

 

thought i would pull the cover off again and take some better pics.



heres the head overall. found out only 7 of 8 rockers flew off, the other exhaust rocker on cylinder 1 held on. seemed like it blew them off down the line after the valve dropped.



heres a better close up of the cam lobes. i scratched them with my fingernail and could not feel any of the scratches AT ALL. im going to have a friend look at it and will probably get it lightly sanded this weekend.



in this one i discovered the the lash adjuster seat is bent up and needs to be replaced, how much of a pain would that be?



there she is sitting in the driveway, brake rotors rusted and bird **** on the back window. yep its been a sad 6 weeks...

so good news and bad news, cams seem to be okay and wont need replacing but the lash adjuster seat will definitely need to be replaced. taking the head off in a couple days to see underneath!

 

Purchase entire head from ZZP, swap out, continue driving.

 

sounds easy enough but what if youre a broke ass college kid?

 

small knick in the piston from the valve hitting it. reusable or buy new one?

 

You could reuse it. Chances of a hot spot happening there are greater and you never know if anything else is wrong with the piston.... If money is available, I'd replace them with some nice Weisco Pistons

Show a picture of the nick... It could be nothing to worry about. Again, you never know though.

 

i mighttt be able to get pictures later but its at a shop right now. definitely no money for wiseco right now i was told its a little smaller than the nail you clip off of your pinky nail when your trimming your nails if you can picture that lol

 

Too bad you cant do pistons man. When I popped one last year I went ahead and got the Wisecos. Glad to see your making some progress though!

 

yeah i wish i could too but just dont have the funds now with rebuilding it and all. should be back on the road in a week or so, hopefully i can get some internals by the winter.

 

The factory lnf piston has a cavity in it for oil cooling the piston head if you dented the top that price may be compromised and could crack causing compression loss and massive oil burn. I would buy new am pistons from zzp or ced may have something as well

 

That's not the lash adjuster seat in the picture, that's the other part of the lash adjuster, you just broke the tip off. Pull up on that piece and it will slide out of the head.

 

alright im just going to get new ones from gmpd bcuz i just dont wana take the risk

oh ok thanks for the info. i was going to rebuild myself but just give it to a shop that will do it for little to nothing
