Well anyways Im going to replace the head gaskets, is this rather easy? is there a manual out there that would cover this. Im assuming its as easy as it looks, drain the oil, and coolant, take the valve covers off then the intake manifold, take the headers off, then im lost. any help would be apreciated. thanks in advance. | | |

WOW, working on a V-8! It's been awhile since I did this task, but I'm thinking you have to loosen the rocker arm adjusting nuts, swivel the rocker arms out of the way to reach some of the head bolts hidden between them. This also allows you to pull the pushrods out.
When you pull the intake you will have to pull the distributor too.
Do some extensive looking using Brake-Kleen and rags on your leak BEFORE you go nuts! As Brian points out above, this type of leak is very uncommon to be associated with a head gasket .

It,s very unlikely thats where it,s leaking. Wash it down real good & look for the leak. Like the guys have posted, check the back of the intake, valve covers, oil sender, or even the dist gasket. If it,s comeing from the clutch/converter cover it could be a rear main seal.

#75445 03/27/2007 3:43 AM | Joined: Jan 2007 Posts: 24 Apprentice | | Apprentice Joined: Jan 2007 Posts: 24 | I was hoping to find the leak today but central texas got hit real hard with rain, so I didnt get to it, but I will mention that the oil is coming from the pass. side towards the rear. most of the oil is below the header, but theres a little above it, it didnt leak as bad as it does now before I changed the oil, but now when its running it pours out, all of which lands on the collector then turning into smoke. thanks again for the help. | | |
