Hi guys, this is my first post and I am happy to be here. I recall several years back I was driving home in my 69 xr7 from Grass Valley area in Northern California. I had stopped in Auburn to get a bite so I was still a few hours away from getting home to the lower Bay Area. When I started the car in the parking lot to leave Auburn, it started up but then all of a sudden I heard a short “metal” sound and the engine started running rough. Well, a visual inspection did not tell anything in the parking lot. After some time I thought, well screw it, it’s highway driving all the way back. Let’s just get it home.
After I got the car home, more tinkering did not reveal any information. Dad came over to help figure this out. After a while dear old dad says, hmmmm, pull a valve cover. After removing the passenger side cover, sure enough, starting the engine revealed the two forward rockers weren’t moving. Broken camshaft. I had driven home with a V6!!
Well at that point the original cam had never been changed so gave us a good excuse to go through the motor Funny now. That was in the late 1990s.
