So I'm throwing around a bunch of ideas with my Dasher. Blew the timing belt and screwed up the head pretty bad. Camshaft in four pieces and big chunks in the aluminum. Gonna check into how much I'd get from recycling it.
Took the bad head off, and the piston tops look good. No scoring or marks into the metal at all. I rubbed off the carbon and they look good.
I've got a 1.6L that I'm rebuilding to put in this car, but I'd like to get this car running again while I take my time getting the 1.6 block all pretty.
So the question is: Can I put the 1.6 head on the 1.5 block with the 1.5 injectors and pump and drive it? Is the camshaft any different between the 1.5 and 1.6, or is it just the cylinder bore that's different?
Someone put a plug in to convert from hydro to mechanical. Should I pull the hydro plug that someone put in the head so that it matches the 1.5 head?
I have two 1.5 heads in the garage, but no 1.6. So, this is going from memory.
The 1.5 and 1.6 blocks have the same bore. The difference is in stroke. I think the 1.5 has an 80mm and the 1.6 has an 85mm stroke.
As for the heads, the early model 1.6 heads had 11mm head bolts. I think all 1.5s had 11mm bolts. The later 1.6s had 12mm head bolts. As I recall, the two head bolts on each end of the block next to the manifold side are used to "center" the head gasket. So, you would definitely have to use the correct head bolts.
I have used the "guts" of a 1.5 and put in a 1.6 block. With that set-up, its still a 1.5. 1.5 blocks are weak on the end next to the fly-wheel. The corner bolt hole can crack.... then its ruined! Before istalling head bolts, make darn sure the bolt holes do not have any oil or other material inside.
Confusing, but making such changes can be confusing.
