sdsurf Posted February 11, 2008 Report Share Posted February 11, 2008 The engine turns over smoothly so I am going to assume it is ok. From what I know I need to yank out the old plug, hone it a little and tap in a new. Any thoughts? Quote Link to comment
kiznook Posted February 11, 2008 Report Share Posted February 11, 2008 first of all, If you are changing one, you might as well do them all. A set is less than $15 as for replacing them, tap on one edge using a cold chisel or shitty screwdriver, this will "cock" the plug in the hole, allowing you to grab it with dome pliers and pull it out. Chances are pretty good that the inside of your block behind the plugs is pretty nasty, so it might be a good idea to clean it out the best you can. Now just clean the "mating" surface with some emory cloth/sandpaper/steel wool sort of giving each hole an abrasive rim job :D Now when you put them back in, try to find a socket the "fills" the plug, best would probably be to find one big enough to sit on the "lip" but not big enough to hit the block. Use the socket to tap the new plug in nice and straight until it sits flush with the block. Done and Done, the hardest one is behind the flywheel, since you cant get to it while the engine is on a stand. But seeing as how you're using a rare steel belted RACING engine stand, it might be fairly easy (once you remove the tranny, clutch, flywheel) at which point you might as well change the rear main seal too /rant Quote Link to comment
banzai510(hainz) Posted February 11, 2008 Report Share Posted February 11, 2008 I say replaced the one! 40mm is the size all else fails thay make a rubber type that you put IN and you turn a nut and it will expan and hold in the block. But if its the steel type plug maybe change them all out. a Guy on the OZdat australia site his went bad ,the one behine the front cover!!!!!!!!! water in oil. some one liked Red RTV on that motor!!!!!

kiznook Posted February 11, 2008 Report Share Posted February 11, 2008 yeah, I forgot about the RTV It'd probably be best to tear the whole thing down and put all new gaskets in...cheap peace of mind Quote Link to comment
sdsurf Posted February 12, 2008 Author Report Share Posted February 12, 2008 All gaskets are easy... anyone check the head and block for straight using a file or straightedge or??? best method please.... Quote Link to comment
