gofargogo Posted December 10, 2010 Share Posted December 10, 2010 I'm doing just the head gaskets on an EJ22 (95 Legacy wagon). Is there any reason to dismantle the heads, or can I leave them all together and just pull them off to check for flatness and swap out the gaskets?

GeneralDisorder Posted December 10, 2010 Share Posted December 10, 2010 The valve covers do not need to be removed but it makes getting to the head bolts easier. GD Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted December 10, 2010 Share Posted December 10, 2010 An Ej22 with blown head gaskets? I'd certainly have the heads milled. I'm pretty sure you have to disassemble the head to have it milled. Quote Link to comment Share on other sites More sharing options...
gofargogo Posted December 10, 2010 Author Share Posted December 10, 2010 Thanks, I'm going to have them checked. I guess I will take them apart. Quote Link to comment Share on other sites More sharing options...
bstone Posted December 10, 2010 Share Posted December 10, 2010 How do you get to the head bolts without taking off the valve covers, rocker arms and cams? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted December 10, 2010 Share Posted December 10, 2010 How do you get to the head bolts without taking off the valve covers, rocker arms and cams? On the older SOHC engines all the head bolts are outside the valve cover. I do not dissasemble heads for resurfacing. The shop I take them to doesn't either. Never had any issues. It's much more economical to leave them together - especially for the later SOHC engines that have an RTV sealed cam case. GD Quote Link to comment Share on other sites More sharing options...
bstone Posted December 10, 2010 Share Posted December 10, 2010 Oh of course the SOHC engine. Thanks, GD. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted December 10, 2010 Share Posted December 10, 2010 Did the 22 ever come with DOHC heads? Quote Link to comment Share on other sites More sharing options...

gofargogo Posted December 11, 2010 Author Share Posted December 11, 2010 Ok, secondary question. I'm trying to put together a parts list, but I want to make sure I'm not missing anything: - Head gaskets - cam gaskets (the heads are getting rebuilt due to poor vacuum) - intake & exhaust gaskets - valve cover gaskets anything else? It had the timing belt & pulleys replaced less than 50k ago. Quote Link to comment Share on other sites More sharing options...
Ionlyhave3suubs Posted December 11, 2010 Share Posted December 11, 2010 Water pump been done recently? If it was mine, I would go ahead and put in a new timing belt. You have used up half of its life and they are not that expensive, and you will already have it off. If your machine shop is not providing valve stem seals, you will need them if your heads are being rebuilt. Quote Link to comment Share on other sites More sharing options...
