Default tick tick tick

So i did a few things to the RS-T yesterday and after i was done i noticed a ticking noise coming from the front of the engine. I'm pretty sure (but not 100% certain) it was not there before.

There's maybe 3/4 second between ticks at idle rpm and the frequency increases with rpm. I was "listening" by putting my ear against a long screwdriver and pressing it on various parts of the engine, timing-belt cover, etc. It seemed loudest when pressed on the plastic piece with the timing marks on it. I wonder if there is a frayed piece of timing belt going around or something? Maybe it's a normal noise that i never noticed before?

At higher rpms, it begins to miss sometimes (the noise, not the engine) and as i mentioned, the frequency increases proportionally with rpm.

Any ideas?


Oh, forgot to mention, i'm running 2000 EJ25 heads and EJ22T shortblock. Don't think that should matter though, all the timing and valve-train stuff is from the EJ25 right (eric?)?

Have you checked if its your spark plugs or wires, one of those might be loose. I had a ticking sound before, found out the cause was a torn spark plug (ignition) wire.

Oh, and 28,6XX miles on the car, i would think the tensioner would be ok. How would i check, do i have to remove the plastic cover on the front of the engine? Actually, it doesn't look like that would be too tough except that i don't have a decent place to work on my car at all except for my folks' place 2 hours away

28k on the car,but you did swap motors which required removal and swapping of the tensioner from motor to the next,was your tensioner with a built in pulley or were the tensioner and pulley seperate,with the tensioner being shaped like a rod.


Start the engine and with a stehoscope approximately 3 inches right (looking at the motors head on this will be the drivers side) listen for the knock,if it is very loud there thn the tensioner is likely your culprit.


Also be careful not to were any loose clothing,knecklaces etc.... as the fans and accessory belts will be moving very close by,and be aware of where your hands are,dont want to lose any fingers now!


Good luck,


Ben,

i'm not sure about the tensioner type, Eric did the swap (Eric v5.7 beta/Eric SS/Mullet Eric )

I'm gonna go for a drive right now and try to dial in the fuel pressure... i'll try to check where you said too.

My timing belt tensioner went even before my first motor... so around the 15-20k mark.

What all did you do to it? More then likely it is just that it has been there and you're just now noticing it, but I suppose it could be new/related.

Yeah,
Tensioners are pretty common,especially the newer style ones,They usually start to leak,then they get noisy.





I hate that friggen banan!

What i did to the car was replace some bad vacuum line plumbing and change the oil. The vacuum line to the RRFPR had been leaking and replacing it changed things quite a bit (i've got another thread going about that).

I tried listening around the area of the tensioner with a screwdriver... hard to say if that's it or not. How tough is it to get to where i can visually inspect it? Can i pull that plastic cover off without removing the outside pulley? Is it hard to get in there behind the radiator and stuff? I need to go take a closer look. The main problem is i dont have a good place to work on it, or time to do it... being in school and working is becoming a PITA.

You need to pull both belts, the tensioner for the drivers side one, then the crank pulley, and finally the front covers.

Hammer hitting the block sound is how I would describe the sound of a bad tensioner(Knocking) trailing of after a couple seconds. Ticking, clearly audible (like fingernail on glass) would be closer to a smashed spark plug or short in the plug wire somewhere.

fyi-my bad tensioner got better after the weather got warmer

Hey if you need a place to work on your car, I have a garage with ample tools. Pretty much have anything you could need. I'm about 5 minutes drive from gateway mall.
