Oye pero mi Chico!!! Como esta todo? Anyways yea, thanks to your post that I read in another thread I'm going to be replacing my chain guides and replace or buy a née tensioner. When you replaced the seal did you put the same one that failed or a better one? I seriously think at least one of my chain guides has to be broken.

 

Yeah it sounds about the same as transfercase chain slap to me when I heard it in the first video.

 

Todo bien meng! Aqui, the car runs like a dream now. Damn supertechs Fd up my head....simply cause I did the install myself and the supertechs require that the head be inspected and cleared properly for them. Something I did not do, so they were touching and binding which cause a whole domino effect of failures LOL
Pero bueno, que le voy hacer? LOL Bought a brand new head all stock and slapped her on with my turbo that got rebuilt by Bryan at BNR with the new wheels and such.

Anyways, I replaced the seal cause it was fraying. The reason for that was very high oil temps. You shouldnt need to replace it. Just buy a new tensioner and install it. New guides are a good idea. Id pop the VC off and check the head real quick to see whats up. Shine a light down into the timing area and see if the guides look ok.

Let me know how it goes bro. Good luck meng!

 

yea but could you imagine how much easier a turbo and manifold swap would be

 

People keep saying its weird but the LNF was designed specifically for the Kappa. How it sits is in its natural form. The Cobalt's got it passed down. 2 years after.

 

Some pics of my engine build


Head is at a machine shop getting port matched and cleaned.

 

Cant wait till you get her back together! gotta piece of your car in mine. lulz.

 

damn thats quite of a pitting on that

 

^^^^LOL Dart, thanks bud.

 

Yea that was from the timing components(Chain guides, shaving from the blown Tensioner). I'm just glad that I started the build now, I've replaced everything all timing components(including Performance AutoWerks Beefier Tensioner) and Main and Rod Bearing. ARP head studs, ARP rod bolts and the Carillo Rods, Forged Pistons etc.

 

how many miles are on the car? just trying to get an idea of wear on our motors.

 

27k

 

omg, are you serious?
in my opinion, that looked terrible if you had 50k, let alone half that...i'm sure it will run like a raped ape after you are finished...lol

 

Yes, so if any of you guys get that starting noise sound yea......... fix it.

 

what starting noise sound?

 

shiiiit. I started getting that (grinding, heat shield vibrating) sound on start-ups recently, and my car is idling a little funny this weekend....
So, it was the timing chain thats making the noise???

 

Yes, when you start getting that noise generally your tensioner could be going bad or chain guide is broken. My situation was that my tensioner went back and my chain guides broke so the chain was slapping all around.

 

you cant base your opinion off that. you should see some of the cars i pull apart. some of the higher mileage lnfs look better the his(no offense op) the last cobalts i tore down with 33k lnf 88k lsj had rod bearings that looked like they came of a brand new engine. it all depends how the cars cared for, whats used, etc etc etc and to my knowledge the op isnt the original owner so who knows how it was cared for. most recent kappa came in with a built motor(someone else built it not us) hadent changed the oil in 5k or so.... blacker then the night sky

as for the timing tensioners to me they are disposable parts. they should be replaced after time if your beating on the car on the street or tracking it. the balance shaft tensioner i recommend replacing whenever you do any sort of servce with it and its removed. would it be harmed if reused(if its in good shape) then not at all but all it takes it a tiny bit of crap to get into it and its garbage.

reason im saying this, is a had a DIY rebuild come in and i re-timed the motor after doing valve springs for him and the balance shaft chain tensioner wouldnt even rotate nor compress back into its cylinder and it was brand new when the guy rebuild the motor. so just triple check and mark everything and anything you can to make sure you dont run yourself into a big hassle

 

Just make sure you take care of your car and have a good tune on it. Youl be set. I change my oil every 3-4k for piece of mind and i sea foam it every oil change as well. 52k and running strong still.

 

so whos doing the build? since you're not in Phoenix...just curious

 

Wow those bearings look like ****

 

Yea they do, all new bearing though.

The build is being done by JR Competition. They are Corvette guys. Omiotek no offence taken. I've had the car for a year, previous owner had it for 5yrs. I'm going to have everything new so I'm not worried.

 

all good. yeah i get cars in all the time that are not taken care of and i would expect nothing less then shitty looking internals but the cars that come in with regular oil changes and maitence look like brand new motors inside for the most part.

 

Yea since I got it I've been using Amsoil and changing oil every 3200. The carbon buildup can be blamed on Cali's shitty 91oct.

 

The thing is that the tune has nothing to do with the tensioner.

I noticed mine makes noise on startup every now and then. Usually when the motor is cold and/or if it has been raining.
