I'm not selling anything at this point so please don't ban me for this (I may soon be a supporting member). I hope to help some owners of the 2AZ-FE.
My name is Jake. I developed a repair for the GM Northstar V8 (the worst head bolt/gasket problem in history) and this repair has been used over 250 times without one failure. I now hold a provisional patent on this.
What beats inserts/wire coil thread repairs? Not having these inserts at all. How about a one piece, dual diameter stud that removes the twisting action in the aluminum block when torquing down the heads? Please check out my website at www.northstarperformance.com/sgstuds.php
Please have a look at the repair method. I would very much like to help Toyota owners as I've helped a lot of Northstar owners (Cadillac/Oldsmobile/Pontiac/Buick)
This beats every type of insert out on the market.
I need a Toyota owner's help:
I need someone to provide me with an engine to develop a stud repair for the 2AZ-FE. In exchange for a 2-3 week engine loan I will install the first run of studs in your engine along with new head gaskets, free of charge. If you'd be so kind as to cover half of the shipping charges to southern Ontario, Canada, that would be very much appreciated. You'll have the best repair method in your engine. This way I can develop the necessary repair that it looks like many Toyota owners will soon need.
I've devoted my life to develop bulletproof repairs for automotive problems that are quite common, but warranty often will not cover. If it helps any, there are about 7 or 8 Cadillac dealerships across the USA and Canada that choose to use my repair method for all Northstars they work on. They have very positive reviews, and not one failure to date - not one stud has failed or pulled out of the block.
Please email me at firstname.lastname@example.org
for any more info.
Off hand, how many head bolts does the 2AZ-FE have in total?
