Is that a 22R motor? My first new car was a 1981 Totota Corona that had a 22R, 4 cyl that looked like that one. Put 200,000 miles on that car before Chicago winters got the best of it and rusted the floorboard right out from underneath me.
Yup it's a 22R. Rebuild with a new timing chain and head gasket. I bought this truck in the early 90's and have used it as a work truck ever since.
If I could have found a set of underwater spark plugs it would save me a lot of work...LOL.
