what keeps timing belt tight

[DoggTalon]

Is it the tension pully or that spring thing and someone was trying to tell me its the oil pump that keeps it tight... im trying to figure out why my timing belt ended up slipping so i can stop it from happening again

Hydraulic tensioner and tensioner pulley. The hyd tensioner could have failed. Buy a new OEM one. If the timing components haven't been replaced lately, nows a good time to do so

Interference motor..... Check before u replace.

The tensioner keep tension on the timing belt and the pulley puts the initial tension on the belt. That is why you first adjust the pulley and then release the key on the tensioner.
There are many things that can cause a slip. The belts age as they get older they stretch and or become hard. The tensioner stop putting as much tension on the belt as required to keep it from slipping.
Replace the tensioner, pulley, belt, balnce belt and pulley as required.

Don't forget to do a compression test. If it slipped you may have internal damage like bent valves.

Good idea always check I had eight bent one time and still ran. It ran awful but it ran.

my balance shaft belt went and slipped timing belt a few degrees and bent all valves. very disappointing.

It happens to the best of us. Give for a good time to build the engine and get rid of the balance shafts.

that's what I did, then 1500 miles later...crankwalk just time to be done with it I guess

I prob should change both of the tensioner on there to be safe and were would be a good place to get some new ones and anything else should change

You could get the parts you need from extreme psi or map performance or any vendor on here should have them. If you order from map they should be to you in a day or two being they are in Minnesota also like you. Or take a road trip to go get the parts from them if you have another vehicle. Also like others have said make sure you do a compression test to make sure you didn't bend any valves.

 

[DoggTalon]

I have bent valves already from when it slipped so would it be good idea to change both tension is there anything else bbc.co I should get to so it doesn't happen again

Yes change all timing components oem try a vendor for parts easy to find parts jnz extreme psi, dealer.

Going to have to pull head and rebuild or get a replacement if the valves are bent. I would take the time to change every seal you can while its apart. Get a new water pump and ALL new timing components, and make a decision either to keep or delete the balance shafts! How many miles on the bottom end? Might not be a bad idea to freshen that up as well!

 

[DoggTalon]

I have a replacement head for it... was planing on rebuilding the other one... is rock auto a good place to gett parts... the car has 200000 on the buttom... what do you mean to keep or not to keep then balance shaft

Just to give my two cents worth on this. Since you say bottom has 200k on it I would recommend rebuilding bottom end as well. I did what you planning do, had bad valves from belt breakage. So I had head rebuilt and new timing components put on, then in only about 300 miles later it spun a bearing and locked up. So ended up rebuilding bottom end. This was mentioned to me but mine only had about 108k on it and it sounded ok before so I chanced it. Wish now I would have listened, oh well live and learn.
