I've got two 911's as of now, one is a rally project that's taking some time and the other is an 87' that I bought with 70k miles a couple years back after sitting for 14 years. The car was owned by a friends father who lost interest and just stored the car. When the car was removed from storage much of the fuel system needed to be clean or replaced due to crud. I've enjoyed the car for about 10k miles and the car has smoked on start and decel for much of this. I assume that the old stem seals and possibly guides are toast. I've heard about people doing in-car changes and i'd be willing to give this a go assuming the guides are not all whopped out. Has anyone actually done this? Is there room with the engine installed to do it?
Another option would be to install my hot 10.7:1 PMO, DC60 rally motor in the car and do a proper overhaul on the 3.2. Just not looking to lose the entire summer with parts stuck in the machine shop or my work bench.
