You take:
1 can of WD40
1 Stereo
1 MP3 player with Agent Orange - in this case an iPhone
1 (or more) hammers
1 set of inch sized socket wrenches
1 set of millimeter sized socket wrenches
1 weight appropriate, danish, former machinist - in this case a nerdy, mechanical engineer, from here on out named "enginerd" as a combination of "engineer" and "nerd", a term invented by my girlfriend
Spray plenty of WD40 on the bolts, and let sit for at least 2 weeks. Do not forget it any longer, as you might end up looking too surprised, when the Mafia-in-law asks about what you are doing.
Then turn on the stereo, plug in the MP3 player and turn on Agent Orange.
Let the frustrated dane scratch the back of his head, until he finds out, he DOES need the millimeter sized socket wrenches - and have him go and pick it up.
Take a (5/8 I belive?) inch sized socket and wrench for the two nuts in the front, and have the enginerd lay his weight in to it. If he comes up short, try to increase the volume on the stereo with Agent Orange playing, and let him try again - this should get them loose. For the aft most nut, have the enginerd hammer a smaller (9/16 I belive?) inch socket on it, and have him loosen it with the wrench. Again, try to increase the volume, if it does not succeed in the first try. For the second aft most nut, have him hammer a 17mm socket on it, and use his weight to untie the nut.
When all the nuts are off, look at them to see, how corroded they are:
After inspection of the nuts (no pun intended!), have the enginerd start hammer out some of his anger on the exhaust manifold in order to get both of them off. When they are off, inspect the water and dirt damage on the manifolds:
And also inspect the intake and exhaust holes in the block:
Afterwards, start looking at the back side of the manifold. Discover it is originally for a Ford-Köln G28T industrial engine, hence the markings:
Now, start to wonder if the entire engine is a G28T. Got to bed. Keep wondering. Finally, fall asleep.
