any tips on how to remove the exhaust manifolds? im getting ready for the big 2.8 to 3.4 engine swap and i need to use my 2.8 manifolds so i need help on how to remove the manifolds on both the engines so opinions please. |
Re: any tips on how to remove the exhaust manifolds? soak with a good penetrating oil . do this several times for several days . soak the bolt heads & the surfaces that the manifolds mate to the heads . this will help removal , chase the threads in the heads . clean well the threads on the bolts you will re-use . clean well the threads in the head & don't break any bolts on removal . good luck . |
Re: any tips on how to remove the exhaust manifolds? Get a broken and stripped bolt remover kit it will probably happen and save time when it does so u don't have to stop work and run to the parts store for tools.. if not u can always return it |

Re: any tips on how to remove the exhaust manifolds? If you're doing an engine swap, unbolting the y-pipe from the manifolds will probably be easier. Then dealing with the rust issues of removing the manifolds will be much easier when the engine is in the workshop. :doh: |
Re: any tips on how to remove the exhaust manifolds? heating the bolts makes them expand, thus they are larger in the bolt holes and harder to remove. heating the bolt holds (ie the heads) without heating the bolts would be the way to go, but this is kinda pointless in reality. just use PB Blaster several times a day for a day before hand, then they should come out no problem. given that the motor has spent it's whole life heating and cooling and reheating, exhaust manifold bolts aren't usually a big issue. |
Re: any tips on how to remove the exhaust manifolds? I just removed my manifolds today. I woke up and sprayed pb blaster on all of the bolts 3 hours later all of the bolts came out with zero problems. The bolts I didn't spray that connect to the y pipe I snapped one. Fml ha ha I'm not sure if I can get the stud off the manifold and drop a bolt in or not. |

Much easier to mess with the engine out of the car |
Re: any tips on how to remove the exhaust manifolds? ^^^ good to know. but what i did was for about a week or two, i would spray PB Blaster all over the bolts 2-3 times a day. They came out like they were brand new and not one broke. |
Re: any tips on how to remove the exhaust manifolds? i picked up seaform deep creep so that should work i hope, also im just gonna leave the manifolds on but i cant find the damn bolts for the y pipe!! |
Re: any tips on how to remove the exhaust manifolds? I need to replace the gaskets in the manifolds on my 2.8, does spraying the bolts with PB blaster work good? |
