Question?
Can I pull things and tilt the engine to get to the manifold? Also, there is one rusted bolt that may need drilled out.
Can I do it without pulling the 2.8 ?

Yes and yes. This tool will be your friend if you have to drill anything:

My advise though is never to use a screw extractor, just drill it out and retap. If you miss and hit the threads, helicoild it and move on. If you break an extractor in the head you will WISH you had followed this advice

I have the jig already. Yahoo, it can be done without pulling. Thats what I need, a Pat on the back. LOL

wgpierce , thanks for the advice. I will not use an extractor. I'll for sure drill and tap.

You can do it without pulling the engine. I just did the manifolds on one of my Formulas and had to deal with 2 broken studs....not fun.

At the very least you need to remove the dogbone and the rear cradle bolts. With a jack under the cradle and the bolts out you can lower the cradle several inches....it may be enough to get you the access you need.

I had to remove the y-pipe as well as the entire exhaust system to get enough room to work on those broken studs. Luckily there was about an inch of stud sticking out and I was able to weld a nut on them and unscrew them. I also had to loosen the AC compressor as well as remove the shifter cables so it would drop down further.

Definitely not a fun job. Just take your time and you'll figure it out.

Any suggestion on what to use to drill with. Do I need a right angle attachment or something?

I would suggest pulling the head to work on it on a bench.

The head can be removed from the engine while it's still in the car.

Yes.

Some images and description of what I went through Here. It's a b!tch of a job. (Robert, read through the whole thread... and possibly save yourself a ton of grief.)

In retrospect... if I had to do it again (drilling out broken exhaust manifold bolts), I might pull the head instead.

Yeah, I just came back in from looking at it with flashlight and yes, pulling the head looks to be the best option. There's 2 bolts that are very bad rusted off.
Also, I can take my time and not break my back.

Awesome info everyone. Where would we be without the forum. I'd be totally lost.

Very much appreciated !

Sorry for the crap you went thru Pat, but that thread really helps keep me out of trouble.

If you have access to a welder, I would weld nuts to them. The heat from the welding process helps break the bolt loose and the nut gives you a good place to get a wrench.

Much, much faster than any of the other methods and had a higher degree of success.
