Subeast-EA81 Posted January 9, 2009 Share Posted January 9, 2009 Well my 98 OBW is up for service, plagued with a low rough idle and a bit of a light knock due to the low idle, plus a leaking power steering pump,... I was thinking of replacing both PCV's, pulling the intake manifold and TB, cleaning it with the appropriate cleaner, i already did new plugs and wires, any more ideas?

nipper Posted January 9, 2009 Share Posted January 9, 2009 Unless you have 2 98's you have only one PCV. Er um that light knock can be worrying. Air filter fuel filter come to mind. Quote Link to comment Share on other sites More sharing options...
Subeast-EA81 Posted January 9, 2009 Author Share Posted January 9, 2009 i guess i might be mistaken on what i see then, i guess what I'm making reference to is the breathers on both valve covers (leaking oil) i did the air filter when i did the plugs, any ideas on the knock? its very light at a low idle, and there is mild clatter at 5-6000 Rpm's, but no different that a EA81 at 5000. could it be the plate on the back of the oil pump?

idosubaru Posted January 9, 2009 Share Posted January 9, 2009 Plugs - are they NGK? Wires - are they Subaru? they should be, though that wouldn't be causing your problems now, not without a CEL anyway. Definitely replace the PCV valve. Next step might be a valve job, they're usually due for one around 100,000 miles. Not sure if they'll make noise though, maybe someone can confirm. Mileage? Has the timing belt ever been changed? Next timing belt job should include all oil pump seals, retighten and lock-tite the rear backing plates and the cam seals and inspect and replace the necessary timing pulleys (should be a couple of them at this age/mileage). Water pump for good measure. Quote Link to comment Share on other sites More sharing options...
Subeast-EA81 Posted January 9, 2009 Author Share Posted January 9, 2009 yes the plugs are NGK, wires are beldin super conductor, as far as when it comes to doing the timing belt and all that before mentioned service you describe gary, would it be easiest to pull the engine and put it on a stand? i know that on my old 84 waggon it was a prety quick task to have it out if you have a friend to help.

This is news to me, and probably everyone else on the board... or do you mean valve adjustment. nipper Quote Link to comment Share on other sites More sharing options...
nipper Posted January 9, 2009 Share Posted January 9, 2009 Belden wires are junk, no matter what level they are. Get a set from OE so then we can have a clean and even place to start from. That knock thing thoug someone needs to listen to first. nipper Quote Link to comment Share on other sites More sharing options...
Subeast-EA81 Posted January 11, 2009 Author Share Posted January 11, 2009 OK so i got it all tore apart, and this is what i found,..., Timing belt has already been replaced, heads have cometic gaskets installed, newer oil pump with tight screws, however the timing looks like it was off one tooth on the left intake cam, (all marks lined up except that one!) is it possible for the EJ25 to run like this? i have a new belt and will re-time it according to the factory service data I'm just trying to make sure I'm not crazy:banana: nipper: called Subaru in Vancouver, got factory wires, they look so much better then the bendins. hopefully that will help a bit.

nipper Posted January 11, 2009 Share Posted January 11, 2009 Yes they can run with timing off, but not well, as you have seen. If That is the issue good. Quote Link to comment Share on other sites More sharing options...

Subeast-EA81 Posted January 11, 2009 Author Share Posted January 11, 2009 thanks guys, im keeping track of the thred, while working on the car, gotta love a little technology in the shop! everything seems to be lining up fine, it was definatly a tooth off, the guy who did it before me used paint pens, not the factory specs, it's really obvious Quote Link to comment Share on other sites More sharing options...
