eqvance Posted February 23, 2004 Share Posted February 23, 2004 just trying to get an estimate on what i would have to pay my mechanic to replace a bent valve. it's a 1986 subaru gl wagon. 1.8l Quote Link to comment Share on other sites More sharing options...
NoahDL88 Posted February 24, 2004 Share Posted February 24, 2004 whats your location, it might be easier and cheaper to get a new head at the junkyard. however unless your in the Pacific North West that may be easier said than done. I don't know prices on new valves in heads, but there will be a certain amount of machining to be done to make the new valve fit, it would be bennificial at this time to get both heads off and put in all new valves and guides, and possibly seats if there hammered Quote Link to comment Share on other sites More sharing options...
MilesFox Posted February 24, 2004 Share Posted February 24, 2004 who is taking the head off/ you or the mechanic? if you have the head off yourself, you may want to invest in a valve spring tool, it will pay for itself if you do valve seals on your own work, the tool is cheaper than the mechanic but if you have the head off, the mechanic wouldnt cost as much, buit he will still charge you an hour at rate Quote Link to comment Share on other sites More sharing options...
ccrinc Posted February 24, 2004 Share Posted February 24, 2004 Why do you think you have a bent valve? The valves in the EA82 heads are HUGE and incredibly strong. Plus the engine is interferential. I mean, this would be really unusual and very rare. So, what makes you think you have a bent valve? Emily http://www.ccrengines.com Quote Link to comment Share on other sites More sharing options...
eqvance Posted February 24, 2004 Author Share Posted February 24, 2004 without looking at the car yet, that's what the mechanic told me over the phone, that it was probably a valve problem. it all started when i broke the timing belt. once the belts were replaced---------engine misfires and no compression. i thought since it was noninterferance engine, once belts were replaced everything would be cool Quote Link to comment Share on other sites More sharing options...
calebz Posted February 24, 2004 Share Posted February 24, 2004 I think Emily may have made a typo. The engine is noninterferential. A broken timing belt will not cause a bent/broken valve. I would be more inclined to believe that the timing belts were installed incorrectly. That would cause it to run like crap and have low compression.

MilesFox Posted February 24, 2004 Share Posted February 24, 2004 sounds to me that if the car runs bad AFTER BEL SERVICE, they were installed wrong you can check the belt timing by removing the outer belt covers, and the bellhousing window rubber plug read this if tou would like to check the belt timing yourself, or show this to your mechanic http://www.warpthree.com/milesfox/subaru/service/timingbelt.htm Quote Link to comment Share on other sites More sharing options...
eqvance Posted February 24, 2004 Author Share Posted February 24, 2004 that's what i'm thinkiing. although i thought all you had to do was line up the markings Quote Link to comment Share on other sites More sharing options...
MilesFox Posted February 24, 2004 Share Posted February 24, 2004 there are some 720 deg crank rotation for the procedure line up the first cam, rotate 360 deg, line up the other cam, rotate 360. then rotate again to bring the first cam back to the peginning step, them rotate till you get 0degBTDC to do the distributor the belt alignment marks will line up when ALL the pistons are in the middle of their stroke, NOT the ignition timing its common for a mechanic to line up both belts up, to odeg tdc, when the cams should be pointing opposite, with the 3 marks in line Quote Link to comment Share on other sites More sharing options...
eqvance Posted February 24, 2004 Author Share Posted February 24, 2004 also, if it was a valve problem wouldnt it be smoking or be making some type of internal noise ? Quote Link to comment Share on other sites More sharing options...
ccrinc Posted February 24, 2004 Share Posted February 24, 2004 Yep, NON interferential is what I meant. Yep, yep, yep. (That's what happens when I try to type before coffee!) Look to the timing belts. Problem is extremely likely to be there. Emily http://www.ccrengines.com Quote Link to comment Share on other sites More sharing options...
eqvance Posted February 24, 2004 Author Share Posted February 24, 2004 what's the normal charge for a mechanic to replace timing belts on the 86 gl anyway? Quote Link to comment Share on other sites More sharing options...
