Is it worth camming my older engine?

whtlegacy · 03-26-2004, 01:37 AM

I've got a DOHC EJ25 with just over 90,000 miles. I need to get my timing belt changed and I understand that this is a good time to install more agressive cams. how many further labor hours is it beyond changing a timing belt to swapping cams?
I'm also interested in whether it is worth it to cam a 90,000 mile engine. I'm looking at the TWE stage I cams for $690. What do you think?

it's about 7 hours labor a side and then you have to re-shim them once you are done

Timing belt change is not a good time to change the cams. A head gasget change is becuase they'll already have the heads off the car.

the subaru mechanics manual says that changing the cams is 7-8 hour process on the DOHC engine. and what do you mean by reshim? does that have to do with adjusting the valve lash?

Is the timing belt change really not a good time? It's got to cut some hours off labor, right?

whylegacy,

Installing the cams requires all the disassembly needed for the timing belt change and then the following:

* Remove the valve covers
* Remove the cam retaining caps
* Swap the cams
* Perform valve adjustment
* Reassembly

In my opinion this is a perfect time to install the cams. You're near the 109,000 mark for a valve adjustment anyway. Most shops charge a flat rate for the valve adjustment. They'd probably just charge an hour or two of labor for the cam install.

Best Regards,
Chris
