I'm working on putting my 86.5 back together many years after bringing it home. I'm about ready to start stringing my timing belt and setting the cam timing. It's been a long time since i took the top end apart. I'm putting on the back cover for the timing belt on the drivers side and am wondering about the bolts. It appears that there are three bolts above the crank and two just below the drivers side cam gear on Wayne''s '89 write up. Do you think this is the same for an 86.5?

 

Hope this helps

I don't know what (if any) differences there are between the S3 & S4 for this.

But here's a good thread on an 86.5. I'm going to guess that there's a pic of what you are asking about in here...

Somewhere.

Both posts were very helpful and confirm what I was looking at in Dwayne's writeup. Thanks Scott and Joe.
