Thanks for the insight everybody. When I saw the opening line of the article: "Cadillac has a rich history of noteworthy engines" all I could see is red. I love cars but I do not keep up with today's technology and I only worked on the cars I have owned when I had to. Sorry for putting down GM so much in today's world but I'm 73 and 1984 seems like yesterday to me.

Yes, the 1984 HT 4100 V8 engine with 135 horsepower was very noteworthy. I bought a brand new 1984 Cadillac Fleetwood d'Elegance that was a piece of crap. The car was cheaply made with cardboard being used as backing for inside paneling. The body was so thin that I was trying to get a spot of rust off of it 7 years after I owned it and under that thin rust spot was a hole you could see through. The engine head gasket went out after 70,000 miles and water was leaking into the cylinder block. I was told because the difference between the aluminum block and iron heads cooling and heating at different temperatures created warping between the two metals and thus the gasket would not work anymore. I went to put a rebuilt engine in it and the only one it would take is the same HT 4100 V8. I replaced it and got rid of the car a few years later because it was a rust bucket. I was also told that GM did not test their own engines. They let the public do that for them after they sold them the piece of crap for an outrageous amount of money. Only GM car I ever owned and will never buy another one.
