How difficult is this job on a M103 2.6L engine? I am getting cylinder #3 and #6 spark plugs fouling with some oil deposits on them. I have so far on my own replaced valve cover gasket, fan clutch, fan clutch bracket and pully, top timing cover gasket, and radiator. SO keeping this mind what kind of tools do I need besides sockets and wrenches...?


Thank you.
ps I am using the proper kind of plugs, H9DC

You will need a compressor to supply adequate pressure to hold the valves in place and a tool to depress the spring and remove the keepers.

What you said pretty much went over my head...I think I need to do some research before I attempt this project. I dont have access to compressed air... tho.

there is a thread that tells how to do it...

even if you had to buy a cheap air compressor it would be worth it...

are you sure that is the problem... is the head gasket not leaking oil
around the edges... what i would do is replace the head gasket and go and
have the head done by a pro ... i just found it for 180 bucks at napa

No the head gasket is not the problem, I do not see any oil leakage. I have to fully diagnose this problem before I seriously think about doing this job.
