I will probably need to replace the exhaust manifolds soon and I'm wondering if I should tackle the job myself. I replaced the risers and found that job to be quite manageable.
Is the manifold replacement more difficult?
Any suggestions or tips to make the job go easier would be appreciated.
You can do the manifolds. Bit more work than the risers yet not too bad.
A general guideline would be:
Remove the spark plugs (You will most likely break them off if you don't). Pre-soak the manifold bolts with PB Blaster or some other penetrating oil. Remove the risers & set aside.
Once you get the old manifold off, clean the mating surface on the head very well. Make sure threads are clean for mounting bolts. (Use new bolts as required.)
Use quality gaskets (Fel-pro, Napa etc) making sure all mating surfaces are clean. Re-assemble.
A few things to possibly watch for: Dipstick tube Oil pressure sending unit & piping. Keeping plug wires in proper order.
Hope this helps!
