SUPER Day!

[Rendon LX-i]

damn that sucks

[Tdurr]

pretty much, had to get pulled on by the tiedowns on the front under the fog light holes and 2 chains. on a 2 lane road with a good amount of traffic. Thankfully there was a emergency lane in the middle that we got to ride in...

[Tdurr]

Bent Valve. I fail. Help me find parts to replace while i got the head off.

i would put something in your signature with large letters, or start a post,there are a lot of people on here with extra pieces and parts floating around.

Tim...junkyard.

[Tdurr]

Mos deff a jy, but question is, how the fuck am i getting to a good one lol.
and ill put up a quick add in the sig.
BTW, good headgaskets(for turbo later), the a18 springs if u can find them at a jy, and anything else u can think of, just tell me, but i do have limited funds.

Well if you can find a way to my house one day during the week we can ride to a local junkyard and you cn probably get the valves for like a couple bucks plus anything else youll need. You could bring your head and we could install em and get em ready to go. I know you have school and all....but you should take a day off haha.

[Tdurr]

lol if i can get a ride ill see bout doing it friday, wut i want is to put it all together at school, just bring the parts cuz taking the head all the way out would be a bitch....

pm me on ia...when it gets back up lol...

[mushroom_toy]

Alright I will.

[Tdurr]

update! got the head off today, and the valve makes kind of a S shape lol.. it smacked the piston good, put a lil nick in it... hopefully by wed, ill be putting everything back together....

[markmdz89hatch]

you have a new valve yet?

...and I was just going to post that you probably fukd the piston too if you bent the valve. After all, it's the piston smacking the valve that caused it to bend.

check all other valves b/c if one touched down, there's a chance the others could have as well, but not extremely likely b/c that's the only one that lost its retainer.

Lemme know if you don't have the valve yet. I have an extra head that I was going to send to a machine shop, but I can pull a valve or two for you and just send them to you. I hate to know that someone's DD is jacked up and they don't have any way of getting anywhere.

smooth out that nick so it doesn't have any sharp edges, or it could form hot spots and cause detonation. any kind of nick or gouge in the piston is bad because carbon tends to collect in them and this is what causes the hot spots. you end up with a glowing piece of carbon in there that ignites the fuel before it's supposed to. the sharp edges on that nick will get hotter then the rest of the piston, because they won't dissapate heat as well.

Thanks for the offer, but im just going to pick up one from autozone, 10bucks, meh, I deff am gonna be checking the other valves tho.

Deff was gonna do that, the lil cut out for the valve in the piston did its job of not smacking the valve and breaking it in half lol. Ill see if i can upload the cell phone pics soon...

also, now that i got the head off i can say that the engine looks brand new still!! only 75xx miles on the rebuild + overbore...

trying to figure out how it hit, broke a timing belt at like 6000 rpm and it did nothing whatsoever to the engine. when i put new stem seals on, i was able to drop the valve all the way to the retainer grove before it touched the piston, that was with the piston at tdc. the valves are never that far down.

[Tdurr]

^^ the valve retainer came off and im guessing the valve fell down some....at 6-6.5k... still not sure how... thats why im replacing the intake retainers on the #1 to be sure it wont happen again...

[Tdurr]

Udate wit pics!!

After being like This for a while,




i got the head off and found this:


This thing, did this:






and when its goes back together, im adding this:

[mushroom_toy]

Damn so now you need a new piston too. That blows donkey balls.

[Tdurr]

^^ no i dont.... lol ziz wheel son...

[2drSE-i]

i think the valve may have hit the piston....

[lostforawhile]

is that a chunk out of the edge of the piston? you need a piston. it's weak there now and eventually it's going to break. go ahead and add the nos i want to see the remains of that piston after it melts.

[89sei89dx]

im about to put on delta 272 cam. what do i do with the valve springs . i got a lil guage what are they supposed to be set at after new upgraded cam

[Hauntd ca3]

i think the valve may have hit the piston....

just maybe eh!
gotta wonder hat the valve guide looks like as well.
i'd use the opportunity to rebuild myself

[Tdurr]

it nicked it, the pistons have the lil grove for the valves so they wont hit eif timing is off, but it dropped some and hit the spot, its no biggie. Looks worse cuz of the crappy camera.

[markmdz89hatch]

i'm with everyone else in saying that the guides and piston might just be shot. that piston does have a clear mark where the valve bent in and kept tapping it. is the bowl all marked up from the edge of the valve banging it?

[mushroom_toy]

Tim I would go ahead and replace the piston. I know its not what you want to hear, but i would do it as a precautionary measure. You know Im cheap and if I cam upon a piston like that I would probably replace it.
