MWLoyale Posted September 6, 2017 Share Posted September 6, 2017 Hi, I am currently cleaning up my heads on my first rebuild and I have some questions. First of all my driver side valves aren't seated flush like the passenger side valves. Will this be an issue if I just put it all together as they are (do I need to replace the valves or seals)? Second, what's the best way to get the clean the carbon build-up? I've been using carb cleaner on a rag and it's only gotten me so far. I'll post pictures soon, thanks.

DaveT Posted September 6, 2017 Share Posted September 6, 2017 AS far as I can see from the pics, it looks like different batches of valves or something was used. Notice the small differences between them. I've never done much about cleaning everything, just get rid of loose stuff, wire wheel the valves if they have lots of crud on them. One engine I rebuilt had loads of crud stuck on the intake side of the intake valves, you can't see it until you remove them. You do need to resurface the face of the heads, either by machine shop, or the post apocalyptic method, to get rid of the marks made by the fire rings of the head gaskets..

djellum Posted September 6, 2017 Share Posted September 6, 2017 (edited) i generally clean with gas and a brush like my dad did. gas will not evap quickly like carb cleaner. put it in a pan with a lid or some flat cover on it so you can avoid the worst of the fumes, and make sure your outside or in a ventilated area. a paintbrush will get most of it, just make sure you get one that can handle whatever solvent you use. i use a small brass brush on tough stuff. could also get some parts washer solvent, works well just in a pan Edited September 6, 2017 by djellum Link to comment Share on other sites More sharing options...
MWLoyale Posted September 6, 2017 Author Share Posted September 6, 2017 Thanks guys, I guess I wasn't expecting to do a valve job but if I have it apart and if I want to do it right I'm willing to put in the extra efforts for a better finished product. Is it necessary to lap the valves? Link to comment Share on other sites More sharing options...
MWLoyale Posted September 6, 2017 Author Share Posted September 6, 2017 And as far as HLAs go, I'm going to replace all. Is melling a good brand? I found them on rockauto.com and they seem reputable. Link to comment Share on other sites More sharing options...
DaveT Posted September 6, 2017 Share Posted September 6, 2017 For general cleaning, I use kerosene. Much safer than gas. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 7, 2017 Share Posted September 7, 2017 How is this a rebuild? Do you mean head gaskets? Link to comment Share on other sites More sharing options...
MWLoyale Posted September 7, 2017 Author Share Posted September 7, 2017 I'm replacing oil seals and headgaskets, among many other new parts. And after examining the HLAs and seeing some of them seized and the fact that one heads valves are not flush like the other head. Yes I think this is a rebuild, but I'm not here to determine what is and isn't a rebuild, I want my engine to run smoothly when I put it back in.

And What I say next is not meant to be any discouragement. But it's not a rebuild. And when selling a car if you described it as having a "rebuilt" engine you would be lying. Rebuild would be new piton rings and new rod and main bearings, and a valve job on the heads to be even close. ideally, it would also include resurface of block and heads, and a new oil pump.....which aren't available so it's basically not possible to truely rebuild an EA82. Again....not knockin yer project. have fun, learn. But realistically you aren't gonna get any benifit out of trying to go all out to restore this engine......not worth it. Throw it back toghether with new gaskets, new spark plugs, fresh cap and rotor and then enjoy it. You aren't gonna make it any better than what it is.

MWLoyale Posted September 8, 2017 Author Share Posted September 8, 2017 One of my valve guides is pushed down due to a stuck hla and/or carbon buildup on the exhaust valve. I want to replace all 8 HLAs because most of them did not pass the lifter test outlined in the Haynes manual. If anyone knows where I can get these without costing me an arm and a leg, please let me know. I've called and emailed Mizpah but got no response from either, which led me to rockauto.com or a oem dealer. but I'm not sure if I want to trust the aftermarket or pay out the wazoo for oem. Or if someone can direct me on how to rebuild my current HLAs I'm open to that as well Link to comment Share on other sites More sharing options...
rdweninger Posted September 8, 2017 Share Posted September 8, 2017 Keep trying Mizpah. He is always busy. You won't regret the results. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 9, 2017 Share Posted September 9, 2017 The carbon buildup is from bad rings. If you don't address that then it will just come back. And if you are doing all this work and it's been burning oil then you need to check oil pump condition, cut the filter and check for metal, etc. The engine is probably a lost cause if valve guides are out of place. That usually indicates overheating, and excessive oil consumption. Which due to cost and parts availability means throw it away on an EA82.
