1G Balancer Belt Broken

[AllenTallen]

Doing maintenance to my 1g and after taking timing cover off notice the balance belt is broken. I’ve been driving like that for at least 200miles(I just bought the car 2 weeks ago) I’m also going to be changing all the belts, pulleys and water pump since I’m here. Thinking of the front main seal as well.

My question is how does this affect my performance being this whole time the balancer belt has been broken? Could this be why I’m having an oil leak? Thank you very much for your reply’s

Its not likely the source of your oil leak, old engines leak oil thats more likely the reason, you need new seals and gaskets all over that engine. As far as performance a broken balancer belt wont hurt performance at all, you should notice more vibration is all.

Hopefully your just getting “good vibrations” from the lack of a balance shaft spinning, you apparently avoided the catastrophic failure of the balancer belt taking out the timing belt when it broke so consider yourself lucky. The oil leak is harder to pin down until you replace the belts and clean up the front case, the broken belt is not causing the oil leak, but the oil leak may have had a part to play in the belt, coolant/oil is good for belts, I would just get in there and replace the belts/tensioners and water pump, everything that comes in timing belt kit, and thoroughly clean up the motor, maybe check the cam seals? Its hard to pin point an oil leak when everything’s covered in oil

Coolant/Oil is NOT good for belts , just correcting my post

It’s crazy because the top motor mount is trash and no balancer belt & she wasn’t vibrating to my knowledge I’m sure she was but didn’t notice since I’m just very excited to have bought the car haha & yes you’re so right I was reading on so many tragic story’s where the balancer belt snapped off and destroyed everything. I’m very fortunate! Thank you for your reply I’m on STMtuned right now going to order the kit. I just notice the exhaust cam seal is leaking! Sorry for the dumb question but what all could be leaking? I’m thinking about changing everything since I’m here. All I know of is the front main seal, cam seals.

Thanks for your reply and very nice GST!! New seals and gaskets could be like front main seals, Cam seals what what else could possibly leak oil in the front I want to change as much as I can while I’m doing my timing belt. thank you for your reply

That’s what the front case looks nice.

We’ll never know until you clean it up, just replace the timing belt/balancer belt, pulleys, tensioner and and water pump, and the cam seals and you should be good, there’s a good ole factory vhs style 2 part video on YouTube that I always followed, it’s not that hard, you just need the right tools and take your time, these cars can be as reliable as YOU the owner decide to make them with a little effort

Yes, like you said can’t see anything with all that 30yr old oil everywhere ok will do I will definitely let you know how everything goes when completed. Idk how long stmtuned takes but as soon as everything comes in I’ll be back in the garage. Do you happen to have a link or know the title of the YouTube? Thank you very much!!

There are 5 seals, one oring and two gaskets. All are potential leaks. At a minimum i would replace the 5 seals. Both balance shafts have a seal. Technically the rear is the oil pump sprocket but it connects to the balance shaft. Front main seal and two cam seals. That makes 5. The oring is under the castle nut for the oil pump/rear balance shaft.
