M42 Oil pan removal
 

What considerations are there for removing the M42 oil pan without pulling the motor. My 95 has a helicoil in the pan with a SAE bolt in from the PO and it leaks. I have another motor to drop in, but if I don't have to yet, perhaps I just swap oil pans.

I have typically done it when the motor is out of the car. In the car swap, I'm thinking it entails:

• Get renewal supplies in advance: Oil, Filter, Gasket, Motor mounts, good condition M42 oil pan, a few spare oil pan bolts, Oil collection pan, cold drinks
• Degrease underside of car in advance
• Prep the replacement pan (Clean, check for cracks, surfaces are true)
• Lift car on stands
• Drain oil
• Rig an engine support mount/bar
• Disconnect any sensors on the pan (Don't recall if there are any on this motor at the moment. I don't think so)
• Unbolt the pan
• Drop the swaybar & subframe
• Remove the pan, check for shavings and debris
• Remove and clean the surface areas
• Check oil pump since it's right there
• Install new gasket and pan
• Replace motor mounts since I'm there already (370K miles)
• Reattach subframe
• Refill and check for leaks
• Cool off and install x-brace
• Zoom, zoom test drive

Miss anything? I'll x-check the Bentley procedure if there is one. Seems basic, but I'm also documenting it as there was no procedure found in search for the next fellow.

Thanks! Rich :cool:

Thoughts? :rolleyes:

Remove the bolts... How much more is involved in removing an oil pan? :biggrin:

/sarcasm


Seriously, the engine will have to be raised somewhat to swap the pans, if not removed outright. This sounds like a job for Bentley!

Ha! Ya, I'm more concerned about pulling the pan at P & P with one of the chain lifts. As long as that is secure, dropping the subframe is no problem.

I'd hate to have it drop on me. :eek:

Not a cool thing... Anyway, it'll be a few weeks, prolly mid Sept before I get to it. Just doing my prep for it. :cool:
