Copy that. With these 1/4 drive tools the bolts are easy.

Oh of course, great idea, I will have to try that. The floppy swivel is the one part of the IM removal that is still slightly annoying.

+1 on Lee and Erik's comments. Never needed any wobble sockets to do this job.

You can never have too many tools. I found a 1/4 drive wobble extension set at Home Depot for $15. I think I'll get that and a flex joint. I already have some regular 1/4 drive extensions. Thanks for all the advise. I honestly did think Home Depot or lowes would have a wobble set at a decent price, so I didn't look before posting.

The wobble extensions are great--smoother more accurate application of torque than a swivel joint when you are tightening down bolts. They can not achieve as much angle but usually just enough.

These are made in Taiwan and the quality is surprising. BTW, I don't work for H.F.

I am planning to replace the intake manifold gasket. It occurred to me yesterday that all of the step by step instructions I've looked at have you loosening the bottom row of bolts and swinging the manifold to the right out of the way. This isn't going to work if you replace the gasket.

What do people do with the maifold if you want to replace the gasket. The obvious answer is to lift it out of the car but maybe there's an easier way and easier is better.... what advice do you guys have ........?????

This is the way I did mine...

So here's my progress today. My wife had people over this morning so I didn't start working until 1:00 PM. I made a lot of progress....got the throttle body off. got all the necessary stuff disconnected, removed and loosened the intake manifold bolts, removed the dipstick tube, etc and then it got dark. So I called it quits for the day and went inside to clean the throttle body,

So...everything went according to plan EXCEPT I had one surprise. There is no flame trap in my car. Maybe someone removed it long ago. ...don't know. Anyhow, where the 5/8 heater hose terminates on the drivers side it goes into a plastic elbow about 4 inches in diameter near the mass airflow sensor. There is a restriction in the line that is 5/16 in diameter here instead of the flame trap.

What do you folks think I should do with this restriction, leave it alone or drill it out to a bigger diameter? It doesn't make a lot of sense to me to increase the hose diameter to 5/8 dia. with heater hose and then choke it down with a restriction to 5/16 dia. at one end.

If you encountered this situation on your car please tell me what you did with it and how well it worked.

There really isn't (shouldn't be anyway) that much flow so the smaller diameter works just fine.
