In searching the web for a fix for a 1999 Deville DTS I just bought that needed a head gasket job I found the 100% proven solution.

Tony has created a fix for the GM extended warranty company because they came to him to create a fix. The known problem was costing them $11,000 per car and that did not fix the problem. He worked on this solution for over two years.

He has been doing this trde secret repair for over 12 years with great sucess. He created a system of putting his own bushing into the block.
He is a machinist engine rebuilder who will also take your engine out and put it back in or you can ship the engine to him.

Tony insists studs or inserts are not the way to fix this problem for more information go to his site at www.cadillacexperts.com or www.expertengines.com . Tell Tony Rob sent you and he will save you a lot of money.

He is very cautiouse at first because other people have been calling him trying to figure out his system. Remember it is a trade secret and he proved to me he does not use inserts of any kind. This is his own solution.
Happy motoring.
