A couple of months have passed and .. I haven’t started to work on the car. But at least I have all required tools now. The most expensive one was the car ramp to work under the car, which arrived 3 weeks ago. A small welding shop here in Germany made it for $600 (converted from €) incl. shipping.
I revised my plan what to address. Firstly, I’m going to replace the passenger side exhaust manifold, which is cracked. I have started to spray creeping oil on the bolts. After doing this 2-3 times I’m going to use my induction heater and then try to remove them. If I’m successful the leaking issues (leaking tranny pan and most probably rear main seal) will be done next storage season.The engine oil is almost new. And I plan to do this with the engine in place from the underside, just by lifting it to remove the oil pan.
If the bolts break then ... I need to revise my plan slightly
