Sort of an update. I thought I had traced a leak to the oil filter stand gasket, but it turns out that what the problem REALLY is (really, this time, I do believe) is a leaking injector. Only at pressure ( or speed ) and that is why I couldn't see it when the car is idling. Plus, it only seems to happen after the car is hot. I have replaced the return hose on all injectors - the leak seems to be from the return nozzle on the injector nearest the firewall - and it is still leaking.
After googling a bit, it seems that these nozzles are just pressed in, and there is precious little I can do to remedy the problem short of replacing the rascal.
QUESTION:
Assume the engine was rebuilt around 1985, but sat in a garage since 1986. I got it in May. It shouldn't have more than 10K miles on it. If I buy a new injector, do I throw anything off? I've found one on the web (parts.mbz), that is under $40 for a Bosch, which is OK, as long as I'm not hosing up something else because of a difference in the pressures in the individual injectors.
Any advice? It's not a super-bad leak at the moment, so I could wait until I see one on Ebay, if 'twere better that I do so.
TIA
