Just bought the truck for farm use and to pull car trailer if needed. When I was looking at it. it had a slight tick on left side and owner said it had small crack in exhaust manifold. Ran the truck over 50 miles to get it here and had no issues, no smoke, no nothing, ran great. Was changing oil yesterday and noticed the leak was very loud while it was idling. When I walked around the truck I noticed it was coming from the left intake side of the head. My first Dodge, and I have never seen an intake that doesn't cover all the back of the heads. In the middle of the heads, behind the the double exhaust ports, the intake and head has a small gap and that is where the exhaust is coming out. Held my hand over it and it is hot air coming out for sure. Right side has same but no exhaust leaking. Something missing from this 85 360? Does he have wrong intake? Or is this normal and just blown gasket or head?

 

its intake gasket leak. the heat x over for the head.

 

Thanks, I'll get gaskets in a.m.

 

bump: anyone else on this forum have the same problem? i havent, or what would cause this? unless the truck has been sitting for a long period of time.

 

 

That gap is an opening in the gasket he used. I have found there is several types of gaskets, some have ports where there are none on the intake, which he used and some that only have matching ports to the intake. I also found there is a exhaust heat block off plates that some gaskets come with.

 

i use the ones that block the heat exchange off. but i havent built a work engine or a family cruiser. i found that if you take short trips most the time they tend to seal them self off with carbon build up.

 

Thanks, hopefully by using the proper gasket this should be a dead issue.
