Here's the formula for the best penetrating oil (from a Forum post I can't relocate):
The April/May 2007 edition of Machinist's Workshop did a test of penetrating oils where they measured the force required to loosen rusty test devices. Buy the issue if you want to see how they did the test. The results reported were interesting. The lower the number of pounds the better. Mighty interesting results for simple acetone and tranny fluid!
Penetrating oil .. Average load .. Price per fluid ounce
None ................. 516 pounds ..
WD-40 .............. 238 pounds .. $0.25
PB Blaster ......... 214 pounds .. $0.35
Liquid Wrench ... 127 pounds .. $0.21
Kano Kroil ......... 106 pounds .. $0.75
ATF-Acetone mix.. 53 pounds .. $0.10
The ATF-Acetone mix was a 50/50 mix (1 to 1 ratio).
To remove a stripped hex bolt, you can use a tool called a bolt extractor. This tool is designed to grip onto the stripped bolt and turn it counterclockwise to loosen and remove it. Simply insert the bolt extractor into the stripped bolt and turn it with a wrench or socket until the bolt comes out.
The broken bolt can be blown out by someone who knows how to use a torch - muffler-shop
The first step is to remove the manifold. If the bolt is sticking out, remove with a vise grip pliers or stud remover. If broke off flush, drill and extract with an easy out or try to weld a nut to it and turn out that way.
If the bolt is stripped, you can try using a different tool or method to remove it, such as using a screw extractor or tapping a larger size bolt into the stripped hole. If these methods don't work, you may need to seek professional help to remove the stripped bolt.
have you checked to see if there is any broken bolt on the manifold, or worped manifold, burnt manifold gasket
To remove a stripped Allen bolt using an extractor, first drill a small hole into the center of the bolt. Then insert the extractor into the hole and turn it counterclockwise to grip the bolt. Use a wrench to turn the extractor and remove the bolt.
Remove your lower passenger side engine mount and you will be able to rock the engine back far enough for the fan to clear the manifold.
The 1995 Honda Odyssey exhaust manifold bolt torque specification is 45 pounds. The exhaust manifold bolts should be torqued in 15 pound intervals.
To effectively remove a stripped hex bolt using a bolt extractor, follow these steps: Select the appropriate size bolt extractor that fits snugly into the stripped bolt. Insert the bolt extractor into the stripped bolt and turn it counterclockwise with a wrench to grip the bolt securely. Apply steady pressure while turning the extractor to loosen and remove the stripped bolt. If the bolt does not come out easily, apply penetrating oil to help loosen it. Once the bolt is removed, clean the area and inspect for any damage before installing a new bolt.
you will have to unbolt the exhaust pipe from the manifold pipe and then you unbolt the manifold pipe from the engine, remove old gasket and make sure both sides are clean of the old gasket and then install new gasket and bolt manifold back onto engine.
It will bolt on, but to answer your question, no.
