turbo engines in general

When a engine crosses over to the marine world you know that is a good engine ,the 4 banger "Iron Mike" Gm made was a tough little engine ,1000's of the old "Iron Mike" engines still up and going in boats every week end here on the river

That statement about the marine world put a smile on my face as we're running a 1969 Gray Marine 671 in our bus. It purrs like a screaming jamming since rebuild.

Is that the old "IRON DUKE"? Those were tough old engines. However, I rented a couple of cars back in the 1990's and they were rough and noisy and made an otherwise nice car unpleasant to drive or ride in. I think those cars were OLDSMOBILE CIERA or CHEVROLET CELEBRITY.

They were called by different names they were all cast iron and were popular in the Chevy and GM compact pickups,now they add more cams,valves and belts to smooth the engines out, 4 grand to change a timing belt as a PM, with a plastic water pump inside the engine? as a Harley owner I like the rough idle

Well the old DETROIT S50 was a pretty good engine but some of those first one's were extremely rough. Perhaps that was the respective bus builders fault but that engine didn't last very long in production anyway. I did ride on an MCI either MC9 or 102A3 with a S50 repower and it was much smoother than the one's in the MCTS's NEW FLYERS here in Milwaukee that they bought in the mid 1990's.

75% of the series 50 built were CNG engines and they were rough with the John Deere designed oil pump balance shafts ,the series 60 CNG was rough too ,M/B and John Deere gave up on the CNG engines Cummins is the only player in the game now and they are not that great just ask the UPS and Waste Mangement drivers.My ISX 15 is not smooth till you put it to work, it likes to work and is not happy unless it is working

I used to do part time work for a florist during the holidays years ago. He had a 1962 ChevyII with a 3 speed on the column and the 153 4 cylinder ( iron duke). it vibrated at off idle and at high speed. OK at cruise. Mileage was about the same as the better 194 6 cyl, but the 4 cyl was Chevy's cheapest car.

I had a couple of those engines in cars back in the nineties. The dealers always referred to them as "Iron Dukes". They were fairly dependable and lasted 200,000 miles plus.

I have the inline 6 in my Envoy it is ruff on Idle but I think it is going to outlast me,the smart guys at the parts tell me I need a map sensor lol that engine doesn't have a Map sensor like other electronic engines

I had an 03 Envoy with the 6 cylinder. I believe it was an inline Northstar. It would really run if needed. Sold it shortly after 200,000 miles. Never burned a bit of oil. Used Mobil 1 synthetic and changed it every 10,000 miles.

Mine is a 2005 I keep it because being a 4 wheel drive it so easy to tow ,lol I never check the oil in it I just change it,the thing has never used oil

We recently purchased a 2008 Envoy SLT 4x4 with the IL 6 and left it up in the Tok AK garage. The coolant is good for -68°F and the battery was removed and placed in the rafters with a Coleman 30W solar maintainer on it. It maybe a couple to three years until we'll be back.up there so dropped the collision with basic required liability and full comp. We'll see how it likes being stored when we get back up that way - & if diesel doesn't drop a whole lot by then we'll fly up thus the reason for stashing the Envoy...

UPDATE. Yesterday, I bought a '23 NISSAN ALTIMA. I will take delivery Saturday.
I pondered getting a CHEVROLET MALIBU given that they had many more available. The ALTIMA S I bought was the last one they had so I was lucky to snap it up. Like I said, I really liked my now destroyed ALTIMA so I felt comfortable getting another one just like it for the most part. It has the same 188HP 2.5L non turbo. While the MALIBU 1.5L 160HP turbo was fine for around town, it did tend to rev above 2k at times while on the freeway 65-70mph in contrast with the 2.5L where it rarely poked above 2k unless I would really push it. To me that meant less wear and noise and I think better MPG. But you guys were great in your perspective so in the future turbo won't be an issue either way. Thanks again.
