|
|
Trying to diagnoise this noise my car is making, it seems to be coming from the transmission, its most noticable when you start the car warm after its been sitting a few minutes, but I can also hear it when the car is close to a wall like in a drive-thru... Its like a ticka-ticka-ticka (best way to descibe it)
Anyway it's really annoying, I know what engine ticks sound like, Im pretty sure it isn't that, you really hear it under the car by the trans, could this be the torque converter? _________________

My friends Heep with a 2.8 made that sound when the flexplate cracked.  _________________

Oh we didn't find the crack it it until we pulled the motor/trans to put a v8 in it. The crack wrapped almost 90% around the flexplate>crank bolts. It was actually kind of scary. |

They do crack.
Is it louder on one side than the other? _________________ A redline a day keeps the carbon away! |

I had the flex plate in my S10 break twice! Ended up being a cable got squished inbetween the tranny and engine when the engine was replace. Ripped the entire middle of the flexplate out where the crank bolts are. I have a picture somewhere of that.
Sounds like the tranny though. You may want to unbolt the torque converter though and see if you can see if the flexplate is good. _________________ E30

Im starting to think it could be cracked, I think it got louder after I tightened the torque converter bolts the other day.. Thinking tightening them may have made a bigger crack?
I can't tell if its for sure louder on either side, if anything driver's side.
What would that tell you Paul? |

| i have to say paul is right, make sure its not an exhaust leak before you tear the whole thing apart, because A: its a PITA to take that all apart and that not be the problem and B: header bolts back out, studded or not they still will back out. i mean i thought i had some really chattery lifters a couple times and i was wrong it was my exhaust manifold bolts. just a thought... |

Definetly, I checked header bolts as I do periodically anyway. Its more of a tick/rattle, not like a constant sound like noisy valvetrain or an exhaust leak.
Im pretty sure it'll all be gone by the time I get a T5 in.... |

In Paul's defense, it usually is an exhaust leak.  |

| You jack it up and stick your hand down by the welds of the Y-ish pipe and such to feel for a pinhole leak somewhere? |
