Default How to check timing on 2002 wrx

I have a 2002 wrx with misfires on all four cylinders and I think to I have narrowed down the problem to timing. I am wondering how to check the timing to see if the belt skipped?

If the belt did skip would it be smart to get and new belt and tensioner and any pulleys that might be bad.

check the timing by pulling the covers off and matching all the marks on the belt are in line with the notches on the rear timing covers

It has 160k on it, I'm not sure what was replaced with the last timing belt change though. I may just want to do a belt change and any pulleys that seem to be bad.

Do you have to take off the crank pulley to take off the timing belt cover? Or does or just slide off around it?

Watch, learn, do it right, and yes, replace all pulleys and tensioner. If you buy a kit online, they make it REAL easy and give you everything you need. Water pump is at your discretion but recommended.

Ok well I don't want to replace belt right now because it should have another 40k on it. How do you pull the crank pulley? Just un bolt it and pull it off or do I need a pulley puller?

Would I just turn the motor over until the timing marks line up to check if it is on and if they never line up it is off, correct? If it is off I'll just replace the whole kit.

Dammit man! Watch the video in the maint section. It holds answers to all you've asked in step by step format.

In reference to the last question. Yes. you may have to turn it several times to get the marks to line up.
