Crossle Posted October 10, 2010 Report Share Posted October 10, 2010 2002 Hyundai Elantra GLS 2.0 DOHC Cannot find a specification for resurfacing the head. The head is warped, looking for the spec that tells me how warped it can be before it's just toast/how much material you can remove? Quote Link to comment Share on other sites More sharing options...
DavidBaustert Posted October 10, 2010 Report Share Posted October 10, 2010 spec max is 120 thou, service is 240 thou Quote Link to comment Share on other sites More sharing options...

EvoXbmx Posted October 11, 2010 Report Share Posted October 11, 2010 Call Silver Drive CarQuest (or walk there). They have a full machine shop. I have a feeling that you have a junk head though. The exhaust valve is too close to the deck and if it needs machined, it will interfere. If its the same as this Kia Spectra I just did a head on recently which I believe is the same engine Quote Link to comment Share on other sites More sharing options...

Dave1647545494 Posted October 11, 2010 Report Share Posted October 11, 2010 you can replace the motor in an elantra cheaper than you can do a head job...... Quote Link to comment Share on other sites More sharing options...
Crossle Posted October 11, 2010 Author Report Share Posted October 11, 2010 mitchell on demand Damn couldn't find it for the life of me on there. I hate it when they change shit around. Thanks. Quote Link to comment Share on other sites More sharing options...
DavidBaustert Posted October 11, 2010 Report Share Posted October 11, 2010 i looked under basic specs and such, it was labeled head gasket surface allowance or something like that Quote Link to comment Share on other sites More sharing options...
Crossle Posted October 11, 2010 Author Report Share Posted October 11, 2010 Well it's warped less than 178 thousandths. The frickin' feeler gauge set I've got sucks I suppose I could have found another set around the shop, but 178 thousandths won't even start to slide underneath my straight edge which is far enough away from 240 that I feel comfortable.

DavidBaustert Posted October 12, 2010 Report Share Posted October 12, 2010 are you sure your straightedge is straight? Quote Link to comment Share on other sites More sharing options...
Crossle Posted October 12, 2010 Author Report Share Posted October 12, 2010 Yes I forget who makes it, but it is actually made specifically for checking block decks and heads. I want to say Central or something? Quote Link to comment Share on other sites More sharing options...
DavidBaustert Posted October 12, 2010 Report Share Posted October 12, 2010 Word. Best of luck with the rebuild. I recently tore down a sonata to replace a cylinder head because a timing belt left go only 1k outside of its service period only to find the valve had broken, put a hole in the piston, and welded itself in the top of the piston.

99FLHRCI Posted October 12, 2010 Report Share Posted October 12, 2010 spec max is 120 thou, service is 240 thou Alldatapro.com says: .03mm (.0012 in) max spec and .06mm (.0024 in) limit That is 12 TEN thousandths and 24 TEN thousandths. Much smaller then 120 thousandths (.120 in) or 240 thousandths (.240) Quote Link to comment Share on other sites More sharing options...

Much smaller then 120 thousandths (.120 in) or 240 thousandths (.240) mitchell said .120 and .240, thats why alldata is much better than mitchell. the metric numbers were consistent though. i thought it was a little on the big side but who am i to question the internets lol Quote Link to comment Share on other sites More sharing options...
Crossle Posted October 12, 2010 Author Report Share Posted October 12, 2010 I'll re-verify, we have both mitchell and alldata. Now that I have an idea of where to look I'll compare with my own eyes and report back for general knowledge of those involved here. Quote Link to comment Share on other sites More sharing options...
Crossle Posted October 12, 2010 Author Report Share Posted October 12, 2010 Ok ondemand is saying .003" (.08mm) over 6" span of head, or .006" (.15mm) over entire span of head requires resurfacing. It did not specify a number for the head being "too warped". Although I suppose I would have to find a cylinder head thickness limit and measure that way. Alldata (not pro) reads in a column "spec" .03mm .0012" AND column "limit" .06mm .0024" which I read as "spec" being if you are at or under slap a new gasket on and go and "limit" being machine work is necessary.
