3yrs ago we owned an '01 Olds Aurora.. Had all the fancy shat on it that you could get... The motor was pretty fancy too... 3.5 litre multi port fuel inj. Had good power the first couple yrs we had it. Then 3 yrs ago it developed an overheating problem.. I had a used car warranty on the damn thing, but instead of replacing the motor the garage tried fixing it.. Took off the heads, had em milled and inspected for cracks all that.. As I recall the intake manifold gasket was blown and was believed to be the problem.. SO in putting it all back together, one of the mechanics stripped a head bolt when torqueing it down..(ALUM BLOCK) Well, they heli coiled it some way or another.. Ran great for about 6 mos... Then started running bad again, and overheating.. Sold it at auction for $2,000. Gave $6k for the car and drove it over 2 yrs.. This site might of had some better ideas on fixing that ole stripped out head bolt hole..
That Mustang I bought has an Aluminum 4.6L SOHC 3-valve engine and I was just browsing around for more info on this engine. Came across this. I've never seen a thread repair like this. Thought it was interesting and that maybe it could be used by some folks here, maybe not. Just passin' it on...
According to "Wikipedia" this is an "Authorized Ford Repair" process.
