hodge Posted May 25, 2007 Share Posted May 25, 2007 Ive replaced my engine after the I had my old 1 was knackered. The only thing that I used from my old engine was the water pump. The car fired up great but only lasted 15 mins tiking over and cut out. The engine had seriously overheated hence why it cut out and wouldnt start again. I left it for a day and went back to it to see if it started and wouldnt even try, starter just span. Ive done a compression and leak test on it and found that only 1 cylinder has compression, and the leak test wont show pressure on any cylinders, air seems to be leaking from pot 3. Further investergation finds that there was no water in the engine but the rad was full this is why it overheated. Ive taken the cam covers off to have a look and I cant see anythink wrong. Everything is fine under there, and moving freely. Im thinking the water pump isnt doing its job. Ive never known an engine to loose compression on all cylinders. Does this piont towards the head gasket or something more serious. Quote Link to comment Share on other sites More sharing options...
Ric Posted May 25, 2007 Share Posted May 25, 2007 headgasket or broken block, warped head not sealing due to overheating Quote Link to comment Share on other sites More sharing options...
Guest PedroM Posted May 25, 2007 Share Posted May 25, 2007 At the first sight, it apears to be some problem with the pistons rings. But that can be some others problems. You can loose compression in the injectors, the spark plugs can be with some loose... But first, change the water pump! Quote Link to comment Share on other sites More sharing options...
absz Posted May 25, 2007 Share Posted May 25, 2007 seems like headgasket if it over heated. have you removed any coolant pipes from the engine to see if water is getting there ? you might have a blocked radiator problem causing the over heating Quote Link to comment Share on other sites More sharing options...
Jake Posted May 25, 2007 Share Posted May 25, 2007 Are you using a cylinder head that was on an engine that over heated? Quote Link to comment Share on other sites More sharing options...
hodge Posted May 25, 2007 Author Share Posted May 25, 2007 Ive removed the top water pipe at the back of the engine that goes into the heater matrix and theres no water in there. The top rad pipe had no water in but the radiator was full. I took the top pipe off the water pump (l bend to top rad pipe) and expected the water pump to be full, it was damp but not full. I bought the engine complete with low milage. As I said it ran great for about 15 mins sounded great. It wasnt reved hard or driven which is why im really reluctant to think its piston rings or a broken block. Is a blocked radiator a common thing. How do I check it.

Jake Posted May 25, 2007 Share Posted May 25, 2007 More likely to be a stuck shut thermostat than a blocked rad, I guess. You can crudely check if the rad is blocked with a hosepipe. Just take the rad out and stick a hosepipe in the top hole and see how quickly it comes out the bottom one. (Don't go mad though). You'll need a rag or something to temp seal the hosepipe in the top rad hose hole. Quote Link to comment Share on other sites More sharing options...
hodge Posted May 28, 2007 Author Share Posted May 28, 2007 Ive ordered a new water pump anyway just to be safe and will check the radiator tomorrow. Quote Link to comment Share on other sites More sharing options...
