  1. Afternoon All Looks like I have the dreaded coolant leak from head gasket below the exhaust manifold. I am 99.99% confident it is here and not the oil cooler and also not the plug in the head as my head does not have the plug in the middle between exhaust ports (15P engine) - not sure if that is normal or not! Engine not using oil and running well. Cylinder balance all good on Nanocom at idle and seems to be running well with no excessive coolant pressurisation. As such reasonably confident it is just the gasket let go between a coolant port and atmosphere. I am fairly sure it is not coming from the exhaust as none of the exhaust ports are steam cleaned (I have had the manifold off since my coolant leakage started and all looks fine). I am a Marine Engineer and have no issues doing the job myself (and have all the tools), but just want to ask for any tips before doing? I have seen a few write ups on the tinterweb and the only real issue I see is how you stop the timing chain dropping off the crank sprocket when you undo the hydraulic tensioner - or is it that it the top sprocket just cannot drop far enough? Other than that seems easy enough although not quite as easy as a Wartsila! I will get a head gasket (Elring 3 hole), top end gasket set and a set of head bolts next week, however any tips gratefully received - I have not worked on such a small engine for ages!! Toby
  2. I've got a 109 with a 2.5NA diesel engine. Recently I changed the headgasket because off an oil leak between head and block. After assembling the whole engine together it produces an ticking noise like the tappets are not adjusted properly. What I've done so far: - new headgasket - re-surface head - new hotspots (after re-surface head, they just stick above the head) - all head bolts set to right torque (and re-checked after some driving) - tappets adjusted (several times) - new injectors - injectionpump slightly retarded because off blake smoke on full throttle The noise seems to be produced by the tappets but I've adjusted them for at least 3 times (0,25mm). Does anyone have an idea what this ticking noise can be? To exclude noises I gave the throttle a blimp an direct shut off the engine. I assume there is no injection after shutting off the engine. The ticking noise was still there, so it has to be a mechanical sound and has nothing to do with injection?!
