So i finally got the funds together to get my 60k service done on the evo. Took it to a local shop, called Autolab here in Kentucky, and got my Timing Belt, Serpentine Belt, Balance Shaft Belt, Timing belt Tensioner, Water Pump, and Coolant changed. All the fluids were changed as well before i got the car. Anyway Billy and his team did a great job and I'm feeling pretty good about it.

I want to ask you all about a couple things however, just to make sure all of this is right and maybe what i can do to fix a couple things.

First off i realized as soon as i got back into the car that the exhaust was a lot louder and dronier than before. Also once i reved past 4k when driving it, it really opened up. I was told that the increase in the sound was normal, and that my previous timing belt was very loose. He said the aftermarket GSC S1cams i have in the car are in place better, now with a tighter/newer Timing belt. As a result it feels and drives a lot "stiffer" or "tighter" hopefully you all know what i mean. This is a good thing! just checking to see if that sounds right to you all. They basically told me my old timing belt was shot. Btw i have 60,770 miles on the car.

Another thing I'm just worried about is after 4k RPMs, especially in 1st when i disengage the clutch, i hear a rattling noise. I was told by my friend that it is exhaust rattle and not to worry about it. It never did it before but now after the service it does. Is there anyway i can get rid of the exhaust rattle, sounds really ricey to me and i don't like it lol. any suggestions?

Overall very pleased and glad i got it done. Im just postin this thread up to see if these things that happened are normal when this service gets done. I'm just a very paranoid guy when it comes to my evo

thanks a bunch!

All that sound shady to me I don't see how an old timing belt vs new timing belt can make the car run better its impossible unless they didn't line the belt up correctly, I would like to tear down and really see if they did a quality job. a 60K service is Maintinance not a performance upgrade. unless your not telling us something. It also concerns me when a shop tries to cover up the fact the car runs different by BS'ing there way out of it. (a new tighter belt is better than your old loose belt) blahh if your belt was loose you would have jumped time your SES lamp would be on and probably would have bent valves I call BS just my opinion.

 

^^^^
I agree. A timing belt either works or dosent. The tesioner pulley constantly applies pressure to the timing belt. Even if it were strecthed the tensioner would compensate and there would be no change in the preformance of the vehicle. This def sounds like some BS.

 

awww damn well that's not good to hear i guess lol, idk i mean i trust the shop they seem like they do real good work, i wouldn't doubt them or put them off as a bad shop or anything they are pretty well known in kentucky.

When all the things were changed there was a noticeable difference to me. It for sure sounds louder and dronier especially at high RPM's the tightness and stiffer feeling i explained wasn't like a night or day difference, it felt different but it felt like they were just new parts and not as worn out. Again i am not a mechanic and r tryin to explain the difference i feel as the driver, i really may be over exaggerating, but for sure the exhaust is louder.

will a brand new timing belt hold the cams and gears tighter? or hold them in place better. My idle sound....the lump lump lump sound is more consistent now as well.

what can i do to check if its mounted right? just take the cover off or what? I dont wanna screw anything up.

could the tensioner assembly go bad or something and not hold the timing belt as tight as it should. he told me it was loose no doubt about it. If the timing belt was loose and then became tighter would i hear a difference, would the exhaust sound be louder?

 

I dont see at all how your exhaust would be louder?

 

idk i guess i will take a video of it tomorrow and let u all hear it and tell me if everything sounds right. It's louder for sure and when i push in the clutch at high rpms the exhaust rattles a bit. it never did that before

 

I agree that the exhaust sounding louder is weird. Cleaning grunge out of the muffler isn't part of a 60k, so what did they do to make it louder if in fact anything was done is the question.
If that belt was really really loose, the cams could change by advancing or retarding the timing but only by a couple degrees at most, and very doubtful that you'd really be able to feel that. Hard to say though, we aren't you driving the car. It's sometimes a good idea to ask for the parts when you pick up your car. Having an old cam belt tensioner in your hand is proof that work was done.

 

I'm wondering if your cams weren't set right and they re-timed it? For the exhaust being louder or rattling, did they take any of the exhaust apart for any reason? Or did they take off the heat shield?

 

what did you pay for this shop to do this?
I mean do these guess work on similiar cars?

 

good thing you failed to read the 3 people BEFORE you who already posted this. I hate when people post with out reading the effin thread.

 

I was the first person to state this. In the second post that you are refering to, i copied and pasted my original statement. I only did so to reiterate what i had said earlier; because it was apparent that the OP had not fully read my post. Thank you for your concern, and you prompt and idiotic response.

 

If you have any issues with Billy's work, contact him on here, on 502 or give him a call and set up a time to take it back to him.

Billy installed 2 pair of cams, installed a Exedy twin disk, and a 02 housing in my old red Evo 8 I had. He will be hopefully doing some work on my 9 here soon when I get some more money.

Billy has worked on numerous local Evo's and owns a highly modified Evo that he has built and fabbed parts himself. Billy is the only local shop I'll take my Evo to have work done on it.

 

Something sounds fishy with Billy...none of the work done would cause louder exhaust and rattles. Maybe you should have a mechanically inclined friend ride with you(other then the first one) and see what they think.
