I've purchased the parts and done my research. Basically, I am seeking some insight here to gauge if my understanding of the procedure is sufficient, that I have acquired all the necessary parts, and to get some tips/tricks/warnings to make sure I don't cause additional damage.
- 4 vehicle-matched ignition coils
- 4 vehicle-matched spark plugs
- Replacement intake valve cover gaskets
- Replacement EGR valve gasket
- Dielectric grease
- Torque wrench
- Matching spark plug socket
- Disconnect and remove intake valve cover (I know this step contains several steps within it, but for brevity I am simply summarizing it as this)
- Protect intake valves
- Disconnect cables and bolts from each ignition coil - note which cable belongs to which
- Use socket to remove and replace spark plugs
- Apply dielectric grease to end of coil boots and reinstall; insert bolts and tighten with torque wrench
- Clean intake surface, apply gasket to cover, reinstall
- Reconnect all cables, retainers, etc. - tighten with torque wrench. Also clean EGR valve surfaces and install new gasket
- Once all parts and covers replaced, test engine waiting for a clean idle, test drive
Key things I want to know:
- Steps where I should exercise more caution; trouble points; high risk of damaging vehicle points
- Complexity of this repair
- Anything else that will help me execute this successfully
I think I have a good idea of what and how to do this. Quoted cost of this repair was enough of a sticker shock to send me looking for DIY solutions.
Thank you in advance for your replies and advice, and I apologize for any mistakes in the above - I'm not a mechanic by any means.
