91 3.8 n/a - Started the Head Gasket Teardown - Couple of Issues
I started a thread in the newbie forum, basically I got a free 91 n/a 3.8 t-bird with 77k on it, it's in good condition but needs headgaskets (kept trying to overheat the last time it was driven about a month ago). The oil is clean, coolant is clean, and the engine is still free, everything looks good so far. Going to take the heads off and either replace them or have them rebuilt.
I pulled the plugs and it appears the passenger side headgasket went, already have the airbox off, spark plug wires out, serpentine belt off, the coolant drained, and the upper intake off.
I'm currently at the lower intake manifold, haven't touched anything on it yet. Here's where I'm concerned a bit though:
-Exhaust Passenger Side- I've been soaking the exhaust manifold bolts and y-pipe with PB Blaster for the past few days but I don't see an easy way to get the passenger side exhaust manifold from the y-pipe. It's rusted on there pretty good and I can't tell where the bolt heads are on the downpipe, it's that bad. What should I be prepared to do or can I drill it out from the top? The manual doesn't really explain enough about removing the manifolds from the downpipe.
-Exhaust Driver's Side - I couldn't tell if I need to disconnect something for the driver's side exhaust manifold from the downpipe? Can I simply disconnect the manifold from the driver's side head and be ok?
-Jacking the car up - I have no idea where I can jack this car up and safely to put jackstands under it, I'm used to working on Jeeps so it's been awhile with jacking up cars. Owner's manual says to use the rocker panels but I think that might be a death sentence on a 24 year old PA car lol. I have to do it to drain the oil and I'm not sure if I need to do it to remove the exhaust. The car is parked on the street (rarely any traffic though) and the driver's side is against the curb, leaving really on the passenger side for access or directly in front of the vehicle. I can't really move the car at the moment as this is the only place I can store it for now.
-AC - Can I unbolt the compressor and move it and the AC lines out of the way without damaging the lines or having to evacuate the AC system? I read on another thread that you can move it out of the way but I don't know if it was after the system was evacuated or not? If there is no way other than to disconnect the system, how can this be done without taking it to a shop?
-Fuel lines - I noticed some of the rubber on the fuel lines is pretty old, is this something easy to replace or is it better suited for being on a lift to do it? I'm buying the fuel line disconnect tool and I have to relieve the fuel system pressure still as well.
-Cylinder Heads - I'm leaning towards junking the heads and buying new ones, there was water in a cylinder before, I think the valve seals are shot, and I don't know the full service history of the car. Where do I find the identification numbers for the cylinder heads?
Thanks for your help and your time.
