2000 LS1 quit running today
 

My granddaughters car quit tonite coming home from work. Tmu, odometer did not work when we bought it not running several years ago. Classic BCM failure 694*** miles showing. I tried a different bcm and got the odometer to work but lost the air bags. So airbags are more important than an odometer so that is how it has been for many years. This is the car I put a 150k mile engine and transmission pair about four years ago. It has had two sets of tires run off it, so what ever that is mileage wise. I suspect 60-70k miles. It has fuel pressure but the pump sounds terrible, I think it lost a chain and all that entails with these engines. I have requested to be notified when the change the oil light comes on but it seldom happens. The light has been on for a while and they put one quart in with the dirty oil. I will check compression this weekend and maybe fix this before the Cobalt. It had a random misfire code earlier this week, first sign of trouble. P0300.

Only had 30 lbs compression in #2. Fuel pump sounds good after charging the battery.

Parts are coming from Rock Auto. Cloyes hard parts and Fel-Pro gaskets and bolts. Going to build this and the Cobalt at the same time, same engines.

Which car will be first? You know you have to get the grand daughter mobile pretty fast.

The grand daughter has acquired her mother’s minivan for the next week or so. She will really appreciate the 30 mpg of the Saturn after driving that van for a couple weeks. LOL

I'm going to b e completely honest and say that I thought I was going to be seeing a different engine and car from what the title of this thread said. But then I read the mileage and realized that it must be another engine. This was before I saw the pictures. That Saturn has seen some things. Has a little more mileage than my '82 Chevy C20.

Parts are arriving for the next few days, head bolts and exhaust valves today. Enough this week to assemble the heads. Timing components arrive Monday. Here is a picture of the bent valves out of Kermit. 6 bent intakes and 4 bent https://cimg9.ibsrv.net/gimg/www.sat...bb74faecc.jpeg
This is so much nicer than back in the mid seventies working in the import shop. We raced a twin cam Fiat and worked on most of the one’s in our town. We worked on two 124 sedans racing in SCCA-H class if I remember correctly.
Fiats were square cut belt engines with a 35k mile interval, the 124s were a higher priced car so they tended to receive maintenance at the proper time. The 128 was a single overhead cam fwd car and it was the entry level Fiat of it’s time. They shared powertrain with the X19 which was a mid engine car similar to the Pontiac Fiero. This engine also was a 35k mile square cut timing belt engine. This series of engines destroyed themselves when the belt broke. The heads snapped off the valves and broke the pistons, if you were lucky it didn’t break the cylinder walls. The head was almost always junk due to damage but also these engines had head studs that would stick to the aluminum head. By the time you got the head pried off the studs it was too bent to bother fixing.

Egads! Some of those valves have Peyronies disease. If I can figure out how to attach the photos, I'll post some pics of a neighbors 1.6 Chevy Sonic engine that I helped him do a swap in because he didn't know how to replace the timing belt and ASSUMED he'd done it correctly. I tried to tell him that his marks were not in the correct position, but he'd been a helicopter mechanic in the Marine Corp and I couldn't convince him to not try to start it and run it the way he had the belt and marks lined up, but he didn't listen. It cost him an engine. I feel sorry for the guys that got any helicopter he worked on!

I was a Marine helicopter pilot, and fortunately mechanics did not work in isolation. They were always looking over each other's work, and everything was inspected by QA before it was released for flight. Part of my duties was as a functional check pilot, and you can believe I gave the work a good once (and sometimes twice-) over before I flew it. I can't remember any time when the mechanical work was not completed correctly. That's not to say they didn't make any mistakes, just that the mistakes were caught and corrected before they could turn into problems in flight.
