I will shortly be selling some parts off a spare K5 engine. Not started stripping it yet so don't know the condition of the top end, but if your needing parts I can soon get the cam and towers off. PM me if your interested and we can work out a deal.Sent from my Pixel 6 using Tapatalk
I thought you had this engine fully apart so, why is there so much sludge in the oil strainer. Engine building is down to clean , clean and clean again. All the oil ways will need a good clean including, the main oil gallery. You will only get the same problem again if there is one small bit tucked away in a oil way
The sealant/blockage, by deduction, must have been present somewhere between the entrance where the oil filter bolt threads are (post filtration) and through the oil galleries from there onward until reaching the supply up the barrels.I agree, that you can't be sure without much more extensive inspection. I don't mind splitting them to work of them, would be more gutted to have it happen again though.
I have seen that jet blocked by a piece of gasket fallen into the oil feed from cleaning off head or base gasket
Hi folks, so I'm making some progress on the repairs and have a few questions...I've got a head gasket but it's not the graphite type like the previous one I used... it was from a closing down, old school bike shop/engineers and seems like it's more fiberous (composite?) and than the previous NE one that came in a set for the whole bike.So how to proceed with it when I'm back at that stage... oil it, use copper spray seal or what?Also another pertinent question that could be a contributing factor to my problem; I'm running a custom oil tank with the original hose unions at the engine end but connected with ID: 14.3mm hose. Do you think this will adversely affect the flow/pressure? Anyone know the original hose ID?Cheers fer now
