all sorts of crap broken...

[Ron Vogel]

So I got a few birfday bux, and decided to tackle the timing chain since my milage has been bad, and it's something I suspected being bad for quite some time.

During the tear down, I found 2 bad idlers, a blown power steering pump, bad waterpump, the chain has no tension on it both sides, and the tensioner had a big chunk taken out of it.

I'm still putting it back together, just taking a little break.

oh, and the battery terminals were corroded too, lol.

Oh, and almost forgot, a big thanks to Sinister Drag Designs. Voytec had a few things I needed last minute and really bailed me out!

Thats what happens when you are laying down those numbers on a poor stock motor

Glad you are having no other major setbacks though!

 

[Ron Vogel]

Just got it done, took awhile for the oil pump to prime...very scary. Runs great though. I took it on a 10 mile drive just to check it out, and it feels 100% better than it has for the past two years. I have to hook up my scanner to got WOT though; I don't want to chance it yet.

11s here you come

That just makes his numbers/times that more impressive for a IC/Rocker car.

Ehhh, I don't know how it will affect #'s. Car felt ok at WOT, it just ran like crap at idle and crusing. When you would lifft off the throttle to coast the car would misfire and pop a lot. Now I'm not getting that at all.

clean terminals = weight reduction

did your car feel sluggish on normal acceration like when merging on a highway and stuff like that? My GT kinda does, and it seems to pull fine at WOT. I need to change the chain too. It has 156,000 miles now and rockers were installed at 60,000 and 90lb springs at 80,000. Fish correct me if i am wrong.

Your pretty much spot on correct.

shut your face.

why not upgrade to a single roller?

 

[Fish]

Stock chains are stronger then rollmaster single rollers. Cheaper as well.

hmmm...news to me. i called zzp (they dont answer my emails) and i asked about replacement roller chains cause i bought mine used. i was told they have NEVER seen one stretch nor replaced a chain due to stretch.

single rollers suck, if they told you they have never seen a problem with one they are lying. I've had people ask me to install these, and I always refuse to.

Stock is still best for all but the most extreme builds.

Yup, I could never tune the idle either. It was always misfiring, and on initial start it would always stumble, then recover. With part throttle, it was like a switch was flipped once you got past a certain point. It would dog down, then just go like nothing happened.

Id say 156K is a good time to change a timing chain. Might as well add a GT1 cam.

or slap a snail on the turd box

 

[Fish]

I wouldnt go that far. Id just do a M90 instead of the snail. Cheaper and more efficient IMO for a L36 block.

The GT does the misfire thing at idle too, it will sometimes make a pop noise and i can feel the engine studder for a second. It always has started up fine with no stumbling.

 

[smug]

hey ron one more question, do I need to pull the pushrods to do the timing chain? I dont want to pull the chain off then have the cam spin because one of the cam lobs has a load on it.

 

[Ron Vogel]

No, you don't even need to pull the rocker covers off. Just about everything on the pulley side needs to come off though.

HOly crap... a DD low 12 second car for how many years??? on a stock trans? with over 100,000 miles??? that gets over 25mpg city???? gm sucks..

 

[smug]

Well i just did the timing chain in the GT and it was wore out lol. There was a nice chunk missing off the dampner and the chain was a bit sloppy. The car feels better over all and the miss at idle seems to have went away. I am happy with it. BTW that crank bolt was a bitch to break loose. My impact would not budge it and it has taken others out just fine. I had to vice gripe the flex plate, get a long 1/2 inch extension with a breaker bar, but it worked.

No cam while in there? :sadfish: Ill be going to snap pics of said parts for you tomorrow.
