Just had my car (MY97 Impreza) for a regular service and which they replaced the timing belt for me. They had noticed that the timing marks where not as specified in the official Impreza manual, and had now set them correctly.

The car runs okay, but the car is wobbling a lot on standstill with the engine on idle. Is this normal?

no take it back... timing belt is more than likely a tooth out

only one way to time them. the marks are easy to read and set up. very simple procedure when rad and covers off. take it back.

definately take it back if its running lumpy ( I take it they reset the ECU )

Having recently rebuilt my own engine a couple of times including replacing the belt the lumpy running is a definate sign of timing being out.

I'll also mention that my particular engine ran like a total bag of bolts when set "correctly" ( if it would start at all..... ) as per manual & I ended up intentionally retarding the crank position by 1 tooth this sorted it out & now running perfectly....

Perhaps just an oddity of my engine or as a result of some previous "mollesting" by another owner just thought I'd mention it

( I did check number of teeth between marks & they were to spec )

Its an easy process to change the timing and theres not really any black art involved, just a little luck if your a total novice like I was... although having done it many times now I would call myself an enthusiastic amature now...

In fact before the service we hand found non factory markings which were a tooth back.
1. Do I set it to factor spec, leaving the very slight idle left-right motion. (Engine sounds normal)
2. Do I re-time it with a tooth back?

In both cases the car boost normally.

the genuine subaru belt has marks on it which line up with each pulley top left is straight up bottom left the mark should be pointing left and the two green marks lining both pulleys together in the middle. crank pully straight up with the indent on the crank sensor housing. top right pulley straight up bottom right pointing to the right and again the two green marks on the pulleys should be together in the middle

Totally agree!
The day after I purchased my scoob, I took it for a belt change and the planks gave it back to me wobbling like £U(K.

Did it always wobble like this? They asked

Could it have been that it had previously been 1 tooth out, to advanced the timing, because it might have an ECU mod?

Just take it back to the garage. It's obviously wrong. I seen a fair few now that have gone in for a belt change and come back a tooth out. They wouldn't be the first to **** this job up.
