vedder37 Posted April 14, 2013 Share Posted April 14, 2013 Have a few questions. First how often are timing belts needing to be done. And the other day when coming up to stop sign i let clutch out and there was a loud banging noise like the motor slapping engine bay. I tried to reinact it and the only way i could do it is rocking it in grass spinning front tires at about 1-1.5k rpms it would do it but once above those rpms it would stop and spin without knock. I popped hood to watch motor and it was moving but motor mounts look fine. Quote Link to comment Share on other sites More sharing options...
mikaleda Posted April 14, 2013 Share Posted April 14, 2013 60k or after so many years, wouldn't be a bad idea to replace them if you don't know how old they are. You might want to pull the inspection covers and check it out before you replace it, it very well could be the belt or it could be something else.

Gloyale Posted April 14, 2013 Share Posted April 14, 2013 CLicking CV axle? Timing belt would not be affected by being in gear or not. Quote Link to comment Share on other sites More sharing options...
vedder37 Posted April 14, 2013 Author Share Posted April 14, 2013 New cv axels im sorry the clunking noise was not related to timing belt question it was a seperate question. It sounds like a motor mount issue but they look find. Thanx for responses. Is there an easy way to check timing belts. Quote Link to comment Share on other sites More sharing options...

It sounds like a motor mount issue but they look find. Thanx for responses. Is there an easy way to check timing belts. Pull the covers on both sides, it might be hard getting the bolts out but just be patient. Once their off use a remote start switch to turn the engine or you can do it by hand but make sure you rotate the engine enough to see the whole belt. Look for cracks, chunks missing fraying, or teeth missing. If you see any of that change it. As for the clunking, I would jack the front end of the ground and do an inspection of the c.v.'s, ball joints, wheel bearings, ect...

Loyale 2.7 Turbo Posted April 14, 2013 Share Posted April 14, 2013 My Subaru "BumbleBeast" has been Running with Coverless Belts for long time without issues. The Clunkin' Sound also could be a Loose Exhaust somehow, so I Kindly suggest you to check it too, once it's Cool! Kind regards. Quote Link to comment Share on other sites More sharing options...
MR_Loyale Posted April 14, 2013 Share Posted April 14, 2013 (edited) Have a few questions. First how often are timing belts needing to be done.

I popped hood to watch motor and it was moving but motor mounts look fine. I had that same thing in my car after I put the engine back in following a removal for timing belts and seal refreash. There is a stabilizer bar that if not really tight will allow the engine to sway. Try tightening the bolts. You need to remove the tire from the engine bay as this bar sits under the tire. In the photo below it is the vertical bar running from under where the spare tire sits to the engine. Not to be confused with the horizontal black bar that supports the tire.

vedder37 Posted April 14, 2013 Author Share Posted April 14, 2013 Mr loyale could u be more specific as to what im looking for that sounds about right front end is tight plus the belt looks new. Quote Link to comment Share on other sites More sharing options...

MR_Loyale Posted April 15, 2013 Share Posted April 15, 2013 (edited) No luck was tight. Did you check both bolts, the one under the tire well and the one attached to the engine? They need to be really tight because this bar absorbs the initial torque when the engine engages the driveline. Is this a 4WD or FWD, Sedan or wagon? The transaxle also has mounting bolts. Check that they and the motor mount bolts are tight as well. Don't just look at the motor mounts, get under there with a wrench and see if you can snug up the nuts.

man on the moon Posted April 15, 2013 Share Posted April 15, 2013 If the axles were just replaced, there are a couple possibilities. 1--Something didn't get snugged down enough. Check *everything*. 2--It is not common, but not unheard of for axles to fail out of the box, especially cheap brands. Worth having a second shop check them out. Where are you? Someone on the board can probably do it for you, or recommend you to a shop. People are on here from all over the country/world. Quote Link to comment Share on other sites More sharing options...

MR_Loyale Posted April 15, 2013 Share Posted April 15, 2013 (edited) Can you always reproduce it or only on occassion? Does the speed with which you release the clutch affect of the noise happens or not? Edited April 15, 2013 by MR_Loyale Quote Link to comment Share on other sites More sharing options...
vedder37 Posted April 15, 2013 Author Share Posted April 15, 2013 I could pull in wet grass get it to spin at low rpms and it will do it everytime. Just did it after checking what u told me to today. Quote Link to comment Share on other sites More sharing options...
MR_Loyale Posted April 15, 2013 Share Posted April 15, 2013 And chance you can get a video of it? Have someone else record while you reproduce it. Quote Link to comment Share on other sites More sharing options...
NickNakorn Posted April 15, 2013 Share Posted April 15, 2013 Check all your drive-train parts for excessive play including drive shafts, CV joints, prop shaft, gearbox mounts and gearbox extension tube. Quote Link to comment Share on other sites More sharing options...
vedder37 Posted April 15, 2013 Author Share Posted April 15, 2013 I will try tonight but idk how to post a video. To answer question about speed when letting out clutch it happens right before im stopped. Example pulling up to stop sign car is almost stopped clutch is in i see no cars put it in first let clutch out to go "california stop" and it does it. One thing i need to do is replace bushings in shifter in process of locating them maybe that will fix it although it sounds like motor hitting engine bay so i dont think so.

rdweninger Posted April 15, 2013 Share Posted April 15, 2013 Sometimes, my disc brakes stick. Then it makes a very loud sound when they release. If the car is new to you... you should inspect the front brake pads, rotor and calipers. Then replace ALL the brake fluid and bleed the entire system. Brake fluid attracts water (condensation) and should be replaced every 2 years IMHO. Other than that, check you engine mounts, tranny mounts, cross member mounts. Make sure it is not in 4wd. Check/Replace tranny fluid. Good luck and keep us posted. Ron W. Quote Link to comment Share on other sites More sharing options...
vedder37 Posted April 15, 2013 Author Share Posted April 15, 2013 I have noticed breaks sticking but that is not this issue. Can the motor mounts be bad and look ok. Should the motor have play in it. I can move motor a bit by grabbing it and moving it but with my hands cant get it to clunk. It has never clunked when starting it. With hood open getting it to clunk i can see motor moving. Im really leaning towards motor mounts. They just look good. Quote Link to comment Share on other sites More sharing options...
man on the moon Posted April 15, 2013 Share Posted April 15, 2013 If you think it may be the mounts, try chocking the wheels, then lay under the front of the car and either move the motor or have someone try to shift it. Look at the mounts and see if they are loose at all. Check the motor side as well as the cross-member side of the mounts. That is the only way to know for sure. Even if they are good, they may still be loose whoever last worked on the car messed with the nuts at all. Quote Link to comment Share on other sites More sharing options...
scoobiedubie Posted April 16, 2013 Share Posted April 16, 2013 Maybe your flywheel bolts are loose and it slips when you reverse the direction of the load to the transmission driveshaft. Quote Link to comment Share on other sites More sharing options...
