simbasupra Posted May 23, 2014 Share Posted May 23, 2014 My block is back from being rebored, has been masked up and sprayed satin black. Im now going to start the rebuild. Ive got a full set of Toyota core plugs however would like to know the best way of fitting them. After reading a few things on the Internet im still unsure. Should I use sealant? If so what sort? Is it best to use a socket and hammer to tap them in? If so should the socket fit on the lip or inside the lip? How far should they be tapped in? Sorry for all the questions. Just want to make sure its done right. Cheers. Quote Link to comment Share on other sites More sharing options...
simbasupra Posted May 23, 2014 Author Share Posted May 23, 2014 Researching a bit more it seems most people use a sealant. I have got some Toyota seal packing black (silicone liquid gasket) to reseal the sumps etc. Would this be ok for the core plugs too? Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted May 23, 2014 Share Posted May 23, 2014 Don't think I've ever used that type of sealant on core plugs to be honest. In that circumstance we use Loxeal 58.11, a thread sealant designed for water, LPG & gas plumbing of most types, it's a yellow liquid, that would certainly do the trick. A socket on the outer lip of the core plug is the correct method of fitting, tap them in so the hole chamfer in the block is just showing, basically just tap them in until they are just below the surface by 1mm or so.

simbasupra Posted May 23, 2014 Author Share Posted May 23, 2014 Cheers. Had a look for loxeal 58.11 on the Internet however cant find anywhere that sells it. Anyone know of any other alternatives? Quote Link to comment Share on other sites More sharing options...

simbasupra Posted May 23, 2014 Author Share Posted May 23, 2014 Thanks again. I can only find them online and not in a shop, so I will have to order one in. Unless anyone knows a store that stocks something suitable. Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted May 23, 2014 Share Posted May 23, 2014 I was doing another little bit of digging and came across this: http://www.permatex.com/products-2/product-categories/thread-compounds/threadlockers/permatex-permanent-strength-threadlocker-red-cup-core-plug-sealant-retaining-compound-detail Now they say paper doesn't refuse ink so don't believe everything you read but going on what these guys are claiming the very high strength (red) thread lock is suitable for installing core plugs as well. Most motor factors would carry a red high strength thread lock from one of the manufacturers, I call it stud lock as we rarely use it for normal nut & bolt assemblies. I can't see there being much of a problem using this type of sealer, it'll certainly get a grip anyway. Quote Link to comment Share on other sites More sharing options...
simbasupra Posted May 23, 2014 Author Share Posted May 23, 2014 Cheers, popped down to halfords and all they had was this, do you think it would be ok? http://www.granvilleoil.com/product_info.php?prod_id=151 Quote Link to comment Share on other sites More sharing options...

pedrosixfour Posted May 23, 2014 Share Posted May 23, 2014 If I'd kept my nose out of it you'd probably have the bloody things fitted by now! Quote Link to comment Share on other sites More sharing options...
Iky Posted May 23, 2014 Share Posted May 23, 2014 If its of any help, i changed a coreplug on the back of my waterpump housing about 3 1/2 years ago and used a really thin smear of instant gasket. Been perfect ever since. Quote Link to comment Share on other sites More sharing options...
