Hello everybody!
In the process of getting my 245T ready to be a daily driver I have ran into trouble. When I got it, it had a bad engine wire harness, the exhaust gasket for cylinder #4 was broken, motor/tranny mount bad and other little things to fix. By now, I have replaced gaskets at exh. manifold, oil cooler adapter, intake mani (did B23/230 manifold change)and throttle body. Did motor mounts, installed an intercooler and bypass valve. Here are the problems:
1.- While disassembling the car, I drained the cooling system. I opened the drain cock on the turbo side near the firewall and I was surprised that no coolant came out.I removed the lower radiator hose to drain the engine. I replaced the thermostat which was stuck closed since the lower part had broken off. Replacing the thermostat did no fix the problem. I noticed that the engine seemed to be running hot while the temperature meter on the instrument panel showed lower than normal operating temp. Now even with the no thermostat installed, still no coolant comes out when the cock is opened. It looks than an section on the cooling system is blocked or coolant is leaking inside the engine, although I have not found any coolant in the oil and the car is not pouring white smoke while running. Any hints of what could be wrong? I am suspecting a bad head gasket.
2.- As I mentioned above, I replaced the original B21FT intake with the one from a B230FT and the engine wire harness was replaced with one off an '83 240T which was in good shape. Now the car has an idle of 2000 RPM. I installed new gaskets and o-rings on the throttle body and manifold, but I did not seal the LH-injector holes, instead, I left these injectors in place. What would cause a high idle? air entering the system around the manifold/throttle body? An error in reconnecting the wire harness or vaccum lines? The car ran fine before this change, so I am not blaming the air control valve for this problem yet. The throttle plate closes well. And I replaced the seals on both sides of the shaft in the Throttle body. Any hints?
3.- This is the last one. Since the B230 manifold has more vaccum fittings, I dedicated one for the timing advance at the distributor. This fitting is located after the throttle plate. Will this cause the high idle, meaning that the advance has to be connected before the TB plate?
This is a long post and I feel like I am abusing your good faith, but I would like to get this car running well ASAP and I am looking forward to driving this car everyday. As always thank you very much for your replies.
