Poorly Engine
Posted: Mon Jan 02, 2012 7:41 pm
Ok guys I have a major problem with my new acquisition, I recently purchased the 1929 New Zealand minor from HVA and have run it around for the last month. Engine seemed a bit rough and I new I had a worn camshaft and distributor drive etc. I have just had my dynamo rebuilt which incidently still doesn't work so that's going to have to be looked at again.
However I digress somewhat...The main problem I now have is the engine which seems like it is trying to tear itself apart. I have a great deal of what appears to be gear noise coming from the front of the engine which I guess could wither be the drive at the bottom of the dynamo and/or the drive at the top for the camshaft (which I know has a lot of play). I also have a massive amount of vibration and noise through the car which is most prominent on the overrun. However this disappears when you press the clutch so it is unlikely to be transmission related.. It was also noted that the noise is less when the clutch is pressed in fully at tickover so I can only assume that the front main bearing may have given up and when the clutch is pressed any end play is being taken up and reducing the racket.
So next job is to drop the sump and have a look inside, my question to you all is does anyone know how much roughly a engine rebuilt will cost as I want to have the head done too and replace the camshaft with a 12/12 type and get new rockers. I don't think it needs re-boring as it was done not so long ago and doesn't burn any oil, so I guess its just main bearings, front roller bearing and I will prob leave the rear main alone if it looks ok as that was done recently too.
Any help would be appreciated please..
