There are a lot of various sensors to unplug. I really should learn their function so that I can determine the differences between the SOHC/DOHC wiring harness connections. More this weekend.

You need to remove the nuts holding them to the intake manifold and they try and pry that crossover tube out, its sealed via o rings but they get seized into the heads. What conidition is that lincoln motor is, by the looks of the contact surfaces on the pullies its been sitting for quite some time, probably exposed in elements.

It's a relatively low mileage engine (~60k miles) but it has set in a salvage yard for two years. I have a 90 days warranty. That's one of the reasons that I am hurrying to get the intake and valve covers off to inspect the internals for exposure damage. It turns over fine.

Yeah getting the crossover tube out is a pita.You are gonna love the 4v.It revs much faster than the old 2v.The extra hp & tq you'll have compared to a non pi motor will def make you smile the first time you drive it.Be sure to have it properly tuned to get the most out of it.Swapping a 4v in my car was probably the best thing I could have done for it.Enjoy it

I found this advice on another forum:

After disassembling quite a few DOHC's, I've found this to be the easiest method of removing the crossover tube without damaging it. Use a large flat screwdriver to carefully pry up on one side at a time at the temp sensor bungs, like so...

I'll give this a try. I can just tell that this is going to give me problems.

Between the age of the engine and the o rings they can be very hard to remove.We had to pry mine out like they said to.We used a big pry bar but I don't think we pryed on a sensor though.It should come out.Good luck.

spray around the crossover with some type of penetrating spray. I agree that thing is going to be a pain to get out by the looks of it. You will want to replace the O rings on the crossover and the one on the back of the head you removed. I always use O rings from a O ring kit I got at Harbor Freight. My car has never leaked

Agreed brand new O rings are a must.Trust me you don't want to have to remove it twice.

Ok here is a fundametal question; since the DOHC engine has a different coil interface, how do you adapt the GT SOHC wiring harness to it? What do I save from the DOHC wiring.?

Most everything is off now. I am seriously considering taking a Dremel tool and cutting the back of the tab that holds down the crossover tube and leaving it on while I remove the intake. And who designed the method for holding down the power steering pump? About six inches of thread with two of them blocked to where you have to partially take all of them out before there is enough clearance to get the two obstructed bolts out. How does one do this with the engine in the car? It is hard enough with it out on a stand. I am now officially scared.

Also, how do the fuel rail disconnect. There are metal spring clips but it looks as if the connectors themselves are some sort of spring-release snap on type arrangement. The problem is that they don't want to simply snap off.

you should buy a Fuel/Ac quick disconnect tool at any chain auto parts store. I would spray WD-40 or something on the spring just to lube it up. Use the tool to expand the spring and wiggle line off. here is a video I found he is doing the AC line but it is the same for fuel

A 10mm ratchet wrench is your friend on those damned power steering bolt. I can take it off while leaving the pressure line attached.

This is what greeted me when I took off the intake. What a bunch of crap in the intake valley...

There was a bunch of crap on the IMRC blades. Now here's the deal. I removed all of the spark plugs. All were not tight. Keep in mind that this engine set in a salvage yard for at least two years. The bottom of the intake had a soup of stale gas and what looked like oil. There were no stripped or blew out plugs but none were tight. It makes me think...hmmmm....

Here I attack the IMRC blades. I got all of them removed but I stripped one small screw. I had to use a Dremel to cut it off and I accidentally scored the plastic. It was in an area where two intake runners were side by side. I figure that even if it leaked, it will not represent a true vacuum leak.

So here is a point of worry...as if I didn't have enough to worry about...This coolant line is very corroded. I'm sure that you can't buy a replacement at the auto parts store. So what are my options??
