Intake manifold removal for spark plugs - need gaskets?

Post by Edsel II » Thu Feb 13, 2014 12:26 pm

Hi all,

Chasing down an oil leak with the oil pan on my '05 500, I noticed that the valve cover gaskets are leaking a bit as well.

I'll be at 90k soon, so I'm thinking of changing the spark plugs when I hit 90k, and while I've got the intake manifold off, changing the valve cover gaskets.

Question for those of you who have changed spark plugs - what gaskets will I need to seal up the intake when I put it back together?

No gaskets needed. The upper intake has a recessed groove in it where the stock gasket sits. The gasket will stay in the groove and will not need to be replaced. Funny you should mention this...I am planning to replace spark plugs tomorrow...

Thanks for the reply! If you hit any snags that I should know about pulling your manifold for your plug change, please let me know, and good luck!

I changed mine once before. No issues that I can remember. I wish the back three were as easy as the front three...lol...

After I get finished today, I will respond again with fresh thoughts on the process...

Here is a good url... http://www.justanswer.com/ford/2msde-ch ... d-500.html

Remember to take off the 8 8mm bolts and 4 torx screws...and disconnecting all the other numerous connections. I also used a 27 mm wrench to disconnect the egr line from below it. Also, remove the 4 bolts on the rear crossmember that connects to the roll resistor mount...and the bolt that goes through the roll resistor bushing. The upper intake also has 2 vac lines in the rear...I left these connected and then lifted and moved the intake forward and sat it on the top of the motor. Remember too that there is coolant in the lines that connect to the throttle body...use a small cup to catch 10 ounces or so.

Edsel, Did you ever get your plugs installed? I finished mine. Car seems to be running a little better. The gaps on the old plugs didn't look too bad. The old plugs were in there pretty tight. I always use a little anti seize on the plug threads, but they were in there pretty tight.

I always change my PCV valve when doing the plugs due it being hard to get to with the intake on.

Thanks for the advice, guys. I haven't changed my plugs yet. Have the plugs on the way, along with a set of valve cover gaskets. Also, my silicone glue patch job on the oil pan isn't holding, so I'll be changing that gasket as well. Ugh.

Also, I would recommend cleaning the throttle body while you are in there...

Yeah.. cleaning the throttle body is on my "every 30k" list, along with trans fluid, coolant, steering fluid and fuel filter.

Looking at the oil pan gasket, looks like the pre-cat exhaust pipe that runs under the pan looks fairly easy to remove, giving full access to the pan. Hope that with the valve cover and pan gaskets I can get this thing to stop leaking.

I never changed my oil pan gasket or valve cover gaskets yet. They dont appear to be leaking. I do have a leak at my compressor, but I am not going to mess with that until my ac stops working.

I wouldn't wait until your a/c stops working - if your compressor oil runs dry, when it stops working there's a good chance that it will send debris through your entire a/c system, which will cost a lot more than replacing the compressor and the receiver/drier. When my a/c leak got really bad, I pulled the fuse for the compressor so that it wouldn't come on until I could change it out.

Dumb question...where is the best location to disconnect the ac lines at? If I do it, I will remove and install myself, but I would take it someplace for a proper charge.

A word of warning... I had the same thought. Bought a compressor and a receiver/dryer. Once I did more digging, I realized that removing the compressor is a huge chore. I ended up finding a shop through a friend that did the install and charge for $500. Originally they quoted me $300 until he took a look under the car. Then it became $500. They ended up dropping the engine cradle a few inches to get clearance to remove the compressor.
