Maxwell-8 4,289 #1 Posted November 13 It is a while since I have been on the forum. All the Horses are doing well. Getting ready to paint the rims on de c141 Diesel project. But I have been spending a lot of time in my Ferguson te-20 with a Perkins p3 diesel engine. It has a knock ever since I bought it a good year ago now. The engine runs good and doesn't smoke. oil pressure is strong, rod bearings are tight, no metal shaving in the oil. Pulled the head, everything looks in good condition, flat tappets, camshaft. cant rock the pistons in the liners and the liners are in great shape. The valvesprings do seem weak. I can move the valves down with one hand. It only knocks when hot and at the higher rpm range. Anyone an idea what this could be? Share this post Link to post Share on other sites
oliver2-44 9,847 #2 Posted November 14 I've never heard or seen a Ferguson of that vintage with a diesel in the US. I wonder if that was a European Model only. 1 Share this post Link to post Share on other sites

Yes it was, and it is a rare engine in Europe as well. Its terrible to find parts for it. , Share this post Link to post Share on other sites
Mike'sHorseBarn 3,014 #4 Posted November 14 My dad has a massey ferguson 35 with a perkins diesel. It kind of knocks like that at high RPM, but I'm pretty sure that's just how they sound. I do hear your valves chattering pretty good. Did you check your valve lash to see if that was in spec? 1 Share this post Link to post Share on other sites

Yes I did, currently rebuilding the head with new valves as they are pretty worn. Share this post Link to post Share on other sites
Mike'sHorseBarn 3,014 #6 Posted November 15 Huh, it could just be a noisy diesel then. I'd say you've done your due diligence then and checked everything so if it was mine, I'd just run it with a smile on my face 1 Share this post Link to post Share on other sites

If it didn't fix the noise, I am going to do just that. Bottom-end parts are no longer available. I have been running it like that for a year and it hasn't gotten any worse.
