Alright! Thermostat housing successfully extracted. I used the Sir Tools oil wrenches and some pipes to get some extra leverage to loosen. Of course I smashed my fingers in the process, and I knew it was coming, but my smashed finger was worth it. I loved Goughary's turnbuckle trick documentation but thankfully didn't have to run to Home Depot to reproduce.

From the Oil Line Madness Thread:












I bought myself a nice set of Hazet screwdrivers recently because I always hated my Craftsman ones. These have a little hex nut at the base of the handle and it came in handy to get some extra leverage to loosen one of the screw clamps where a flat blade screwdriver is all that is possible.




My handy leverage pipes because I have the strength of "Mr Burns" (Simpsons reference) in my arms.




Look at this nastiness hidden behind the thermostat housing (didn't get to it with the steam wand).


Now to dump all clamps and parts into the Ultrasonic cleaner after a quick clean in the regular parts washer.

Are you going to replace the thermostat internals?

Well now that you did what you did...you have to clean out the thermostat- so you'd better open it and at least replace the seals...

There is a trick to the reassembly though, so be mindful.

Thanks, I think, I will add it to the parts list. And thanks for providing these links to me on Thermostat overhaul.

And the tank is out! This job totally sucks but I took my time and everything went smoothly. All that is left is to remove the main oil line. Hope I can break it free without removing the rear bumper.

What a mess. Now I need to order parts an re-assemble. I got the main line out without removing the bumper with the Sir Tools oil line wrenches and my leverage pipes on the end to crack it open.

The main oil line is ok but I don't trust it. I will look into getting it rebuild at Elephant Racing and report back.




Carefully washed up the tank keeping water out of the inside. I will probably flush it with oil before install in case any spec of dirt got inside.



Oil tank area BEFORE steam cleaning.



And after (and yes Goughary) careful not to get water in the lines, you would have to aim the nozzle directly up the pipes to do so.

It is ready for re-assembly. Hope I can get parts before my upcoming 4 day weekend but plenty of other work to do.

OK Ricardo - you're my new hero. I looked at all that stuff when my engine was out and decided to just replace the rubber hoses going into the thermostat and oil tank. That is what appeared to be the source of my oil leaks. I admire your complete redo as a much better job. In my defense - I wasn't sure if anything was going to work when the engine went in since I had never seen the car run. I figured I'd better save some halon for the biggest fires. As it turned out (knock wood) things look dry so far with the engine in and running. I thought the thermostat seal was leaking but after driving the car about 30 miles it seems to be ok. I decided to replace all the oil sending units on the engine since they are hard to reach post install

If the rocker panel clips broke but none of the fittings for those clips broke on the rocker panel - then you did good. My clips broke and left the other end of the clip on the rocker panel. Since they have to be replaced I used some side cutters to cut the remaining part of the clips on the ends rather than try to pry them off. Once cut they come off easily. It would really suck to get the rocker off and then brake the fittings trying to pry the remainder of the the broken clip off.

When I put the metal oil lines back together on the thermostat (I reused the old lines) I wrapped the threads with some yellow teflon tape for natural gas fittings. Things went together and have not leaked.

Deja vu all over again! I completed this work over some months last winter, mainly because the upper bracket for my oil tank had long gone and was replaced by a rusted hole into the car.

The pace you're moving along at is impressive.

Another steam cleaner user here too.

The steam cleaner is a great idea although my wife will shot me if I steel hers to use on the cars. Have you guys ever tried one of these. I find it does a decent job.

Here is my project for the long weekend. I won't be able to get to it all as I don't have all the parts but first it starts with steam cleaning.

Nice project you have going.
I am not experiencing any leaks like you were, but would love to refurbish/change some of the lines in the rear passenger wheel well.
