Hi
I have had a noise develop on my 54 2.5 174 with nearly 170k. The noise started about a thousand miles ago after it was serviced with the correct oil when the alternator pulley was changed. At tickover there is a kind of thumping noise which comes from the engine side when the pipe on the EGR is removed. At over 2k revs it changes to a tappety noise and gets worse the higher the revs. It also smokes on startup now like it has been sitting for a while. I have had a search and listed possible problems below.
Low oil pressure
camshaft/lifter wear
Injector seat wear
Cracked manifold
When I changed the pulley I also had the intake manifold off to clean it but did not replace the rubber gaskets as they looked Ok. Not sure if this would cause this noise if it was leaking? I also changed the glow plugs.
Can anyone tell me if any of the above would suit the noise it is making? Any help would be appreciated to save me pulling everything apart.
Thanks
