edakotaford Posted October 23, 2013 Report Share Posted October 23, 2013 i know where to buy them, just curious if anyone has done it, how they liked the results, and if they would rent it out? Quote Link to comment
Dawa Posted October 24, 2013 Report Share Posted October 24, 2013 cooool maybe hit up some machine shops? Quote Link to comment
edakotaford Posted October 24, 2013 Author Report Share Posted October 24, 2013 yeah, i am going to ask around. ive seen that a lot of bmw guys are into the Isky tool though? with good results too. http://forums.bimmerforums.com/forum/showthread.php?1532029-ORings-The-consolidated-thread looks pretty good? the tool is about $300-340 depending on where you buy from.

dvdswan Posted October 24, 2013 Report Share Posted October 24, 2013 very cool. I'm curious though... I've never seen these rings in a block before, I guess mainly because I've dealt with GM and Ford engines. what is the purpose of that ring? doesn't the head gasket have a lip built into it already?

edakotaford Posted October 24, 2013 Author Report Share Posted October 24, 2013 datzenmike can probably shed more light on it than I, but essentially it helps make a better seal by more pressure crushed around each of the cylinders. used a lot in high compression N/A engines and turbo/supercharged applications. I am working on a turbo/efi L20b right now. Quote Link to comment
dvdswan Posted October 24, 2013 Report Share Posted October 24, 2013 thats very cool. honestly have never seen it. Quote Link to comment
datzenmike Posted October 25, 2013 Report Share Posted October 25, 2013 The wire sits proud of the block about 10% of the head gasket thickness and forces a very tight pinch ring around the cylinder that short of a warped head, is virtually blow out proof. Quote Link to comment
Komeuppance Posted October 25, 2013 Report Share Posted October 25, 2013 O-Ringing is common on boosted applications. You can get a machine shop to cut grooves and install orings for you for a good price, much less than buying that tool. You also can consider cutting the head for rings instead of the block, depending on if blocks or heads are easier to come by and ease of removal and installation. -Robert Quote Link to comment
edakotaford Posted October 25, 2013 Author Report Share Posted October 25, 2013 absolutely, i am going to look into that. Quote Link to comment
OkieRA29 Posted October 25, 2013 Report Share Posted October 25, 2013 yep, boosted applications use this a lot. I had a buddy that did a copper HG on his turbo camaro... forgot the O-rings... Copper HG lasted about a month, but when it blew, it was lots of fun. He was running an 88mm turbo and around 25 psi. He was burning oil so bad, it looked like we were leading the invasion of nomandy. Needless to say, the block was O-ringed the following weekend. Quote Link to comment

datzenmike Posted October 25, 2013 Report Share Posted October 25, 2013 The sharp edges in the valve relief cuts. Heat will build up there. Sharp edges are a no no. Quote Link to comment
edakotaford Posted October 28, 2013 Author Report Share Posted October 28, 2013 mmm, i understand now! Quote Link to comment
