Hey guys and gals

Had my timing belt snap on my ea82t passenger side. The repair shop fitted a new belt but now its running like a dog....... any ideas? bent valves or wrong fitting of belt

 

Thanks in advance

Well i don't think it's a Valve issue because you can't damage anything by having a T-belt snap. The thing it could be is that the Timing is off by a little bit. Maybe when he did the job he could have went with the wrong markings on the flywheel.

 

Can you discribe how it's running? Rough, Poor idel, Missing ect...

 

From what i've heard about Repair places is that there not really good with Subaru's. If you want more info heres a link Clicky Alright!

 

I'm sure a Guru will stop by soon.....

 

Good luck

It sounds like the timing might be off a bit. They might not have got everything lined up when they put the car back together.

No way! Someone agrees with me!

 

That's like the only thing i can think of. It's a Timing mistake. I'd take the car back and have it done right and for FREE!

Its just a guess, though. Check everything under the hood. A plug wire, or vacume line or somthing could have gotten knocked loose.

the cams were not lined up properly. two things are very likely, either the person installing them does not know how to do older subaru's (they are the opposite of just about every other engine). you can just ask them. are both cams lined up the same or are they 180 degrees off? they should be 180 degrees off, but probably are not. when one is at 12 oclock, the other is at 6. not so with just about any oher engine, so people mess this up quite often. tell him to just rotate the passengers side (easiest one).

 

or one cam is off by a tooth.

 

bent valves or wrong fitting of belt

bent valve is impossible. it should run exactly like it did before the belt broke with a new one installed.

Well yeah it can be anything like that, But since he took it to a shop to have the T-belts done that is the most likely problem.

 

And that's the one thing i don't understand about repair shops? Why can't most of them do Timing on a older gen Subaru right? Don't they use the FSM's? Or some sort of book?

Or some sort of book?

it is bizarre, i hvae seen improper timing belt instructions i think for the XT6 timing belt...i guess the Chiltons (only one available)? the FSM even has a few errors, but not in regards to timing belts of course!

your mechanic installed the belts with both cams up. he should do one side then rotoate the crank then do the other side. common mistake.

 

i have seen a PERFECTLY goos 88 dl fo for 80 bucks after the previous owner spent 400 bucks on the timing belt. because the one cam was upside-dowen

 

same goes for the xt-6 that tomrhere picked up a while back.

 

i wrote the book on timing belts look it up!

He's serious.

Yeah it's great!

 

I have it printed out:clap: Along with the Oil pump one!!!

ok here is an update.

 

It wont start now. It has spark, fuel and even checked compression. Timing is correct short of pulling off the head covers to check.

 

Any ideas?

Pull off the covers and look. Like GG and MilesFox said, most likely the mechanic installed both belts at once and set both cam timing marks "up". Engine doesn't run too well on 2 cylinders.

No timing belt wasnt put on at same time one mark is up and one is down. What happened if they put the cams wrong way? (instead of marks up/down they should be down/up)

In that case I believe the distributor would be 180* out, which would make it not run.

 

To check:

crank engine over by hand until the dot on the passenger side cam is at the 10:30 o'clock position (45* CCW from straight up).

 

The rotor should now be pointing at the #1 sparkplug on the cap (closest to the hill-holder spring).

 

 

If that's the case, you can either take the disty out and move it, or take the belts off and re-do the timing.
