WoodsWagon Posted February 17, 2006 Share Posted February 17, 2006 After cleaning up and rebuilding the bottom end of my EJ22, I checked the dimentions of everything in the head and cleaned up any carbon deposits. I didn't have the money to have a valve job done, so I reassembled everything with new gaskets, water pump, and whatnot. I finally got it properly timed today, and I noticed that my intake valve leak. You can hear air hissing past them when I crank the engine by hand. Will this solve itself when I get the engine installed and running, or should I tear the heads back off and down and pay for a valve job? Link to comment Share on other sites More sharing options...
tunered Posted February 17, 2006 Share Posted February 17, 2006 i bet you about fell over when you heard that,i would take them back off and at least get some valve lapping compound and reseat them. ed Link to comment Share on other sites More sharing options...
WoodsWagon Posted February 17, 2006 Author Share Posted February 17, 2006 I did say some unprintable words. The engine ran fine before I took it apart, so is it unreasonable to expect that things will reseat themselves? Link to comment Share on other sites More sharing options...
a97obw Posted February 17, 2006 Share Posted February 17, 2006 I'd guess quite a bit of that air leak you are hearing is air going the other way---past the piston rings----since you are turning over a cold engine by hand. I wouldn't worry about it. Link to comment Share on other sites More sharing options...
tunered Posted February 17, 2006 Share Posted February 17, 2006 since its allready together i believe you might as well give it a try,might have been leaking before,just not enough to make any difference.if you have any problems at least you know where to look.

1 Lucky Texan Posted February 17, 2006 Share Posted February 17, 2006 I think a compression test or 2 shouyld tell you if there's a major malfunction. maybe track it after a coupla months of driving. I dunno Carl Link to comment Share on other sites More sharing options...

At the very least, everytime a cylinder head is torn down, you need to lap the valves to give them a good seal. It is cheap insurance. Cranking the engine by hand, any engine, you will hear air leaking, its normal. Remeber the engine is made rto seal at better then 100 rpm, not one rpm every 3 minutes.

WoodsWagon Posted February 18, 2006 Author Share Posted February 18, 2006 So you think that it will seal well enough to perform well at running speed? I've got another ej22 I can rip the heads off of to rebuild eventually. So I'll keep an eye on it and hope for the best. Link to comment Share on other sites More sharing options...
