Hi all, If you remember a few weeks back one of the valve springs broke as I was driving along. As a quick fix I decided to use the cylinder head from my old engine (which broke with bottom end trouble, or so I thought...).
I have just dismatled the top end on the old engine(first time I have ever done this and very easy it was too!). Once I had removed the rocker cover I noticed that the retaining nut on rocker pedestal 4 (for No.4 cylinder) had come off completely and was lying on top of the cylinder head. There was also a gap of 2-3mm between the bottom of the pedestal and the head. I also found a suspecious piece of metal in there which on closer examination turned out to be a 40 degree section of pedestal 3 from where the rocker shaft would pass throught the pedestal. The other slightly odd thing was that the rocker arm for the exhaust valve on No.3 cylinder was not touching the push rod, there roughly a 8mm gap in between them and the push rod seemed to sit lower than the other pushrods. I am assuming that the rocker shaft is probably toast as it is most likely bent. As it is only the cylinder head that I want to swap over can I use the rocker shaft and push rods from the new engine with the cylinder head from the old engine? Is there anyway that I can check that the valves and springs are all ok? I have checked them all visually and they seem fine to my un-trained eye. Also could the problems that I detailed above have been the cause for the engine making the regular clunk, clunk, clunk noise that prompted me to put the new engine in? What could have gone wrong to cause all those problems and why is one push rod sitting lower than the others? Assuming that you lot tell me to go ahead and put the cylinder head on is there anything else that I should do before fitting it like cleaning up the surfaces, bores, pistons etc? Once the old cylinder head is on the new engine I was going to change all of the valves and valve springs and get unleaded valve seats fitted (can I do this myself or would a garage have to fit the valve seats?). Help, as ever, very much appreciated... cheers John http://www.spit1500.co.uk/ Sign up for SBC Yahoo!
