EA Falcon problems
Hi, just picked up an EA,
it has overheating problems. the radiator was replaced last year apparently (and does appear new) a new waterpump was also installed. There is a leak in the metal pipe that goes from the radiator around the drivers side of the engine, and behind the block, this forms a T piece that connects to 2 hoses. anyway in the T section it appears to be corroded and prob needs replacing.
Any ideas on what this pipe would cost. But I dont' think this is this the main problem. There appears to be no coolant circulating through the engine. The lower hose going to the radiator is luke warm when the motor is running however the high hose that goes to the thermostat does'nt appear to have any water flow and gets very hot (could only hold it for 10seconds before it became painfull). I haven't disconnected the top hose to check, but by pressing the hose, it doesn't have the feel of water flowing through it.
One guy said my head gasket could be gone, is that possible and how does that relate to my heat problems? There is no coolant in the oil, nor is there oil in the coolant, there is no major oil or coolant leaks, only the minor one in that t-piece of the pipe I already mentioned (btw what is that pipe called, if I wanted to get one from the wreckers?). He said something about the gasket going on 2 cylanders being common, and a possibility. Is there a cheap and easy way to work out if a head gasket is blown on the one of the cylanders?
oh btw, this bloke is a mechanic and owns an EA falcon, so IM" sure he knows what he's talking about, just could someone explain how blown head gaskets have a bearing on coolant circulating around the engine?
What is the usual cost of replacing a head gasket in an EA, and the maching required. The bloke I spoke to mentioned $200 - $250 including maching, which sounded ok to me, but have no real idea what the usual rate is for such a proceedure. Anyway I'll get back to him in the next couple of days sounds like a good bloke.
Oh yeah, motor also has a clicking, after about 5 or 10 minutes idle, and also has incredibly poor fuel economy. any idea what could cause either of these problems. Oh and one other symptom maybe related to the others, it suffers from run on after ignition is turned off, after the motor gets too hot.
thanks for any ideas,, ps i have no mechanical knowlege so don't presume I've checked the most obvious of things.
