running hot and power loss

Post by hondaeater »

Hello everyone I'm new to the forum and I'm having a few problems with my rig

Its an '85 B2 2.8 carbed 5speed with 155k

I drove about fourty miles (one way) to philadelphia yesterday
With no problem. On the way home however the truck was running
Very warm and it felt very sluggish. Getting to highway speeds was
An uphill battle

I thought it could be a vacuum leak which would explain the power loss
And if it were a big enough vacuum leak it could be running lean and in turn
Running hot. Oil is not milky, no smoke coming out of the exhaust so I don't
Think its the headgaskets. Cooling system hoses are pressurized but when I
Release the pressure by taking off the rad cap it doesn't hiss like a normal
Pressurized system. Its not overheating but the needle stays between the n
And the o in "norm" so the temp is pretty high up there

It feels like it won't go over a certain rpm even if I downshift. This truck is my daily driver and I need it to stay reliable through the winter. Could someone please point me in the right direction

Also the idle seems lower then normal
