Has anyone got any top tips for painting with cellulose like how much to thin by what sort of grit to use to prep the old paint beneath??

Anyone know what the thread of the boost control fitting on a 300 turbo is?? Cheers

Has anyone got a definitive answer on the temp sender issue for disco motors in defenders? got a disco motor in my '86 110 which used to be 2.5NA with a steve parker sender and it still reads hgh, when the motor was in the disco it always ran pretty cool. Can anyone reccomend a sender that works at the correct temp range as the 110 setup reads the temp in the head not at the thermostat housing. Or maybe a guage that will work at the right range?? Cheers all

I have had this problem on a 2.5 NA. It was after bending a conrod (hydraulic lock!!) which after rebuilding with a new rod and headgasket turned out to be a barely visible crack at the bottom of the bore where the rod had hit. Having said that I would make doubly sure its not the headgasket first as this is the most likely place for a problem. Good luck hope its just the gasket

Startup up vid is not unusual for 2.5NA, as you say the white puffs are unburnt fuel as when cold the fuel doesnt readily atomise due to the non direct injection design and relatively low compression ratio (for a diesel). As for the increased crankcase pressure, this would indicate worn rings as you say, I have rebuilt these engines and in my experience a fair bit of crankcase pressure is normal. From the vid I dont think its the head gasket as you would have noticed other symptoms such as loss of coolant or increased pressure in the cooling system, the steam is usually condensation in the crankcase vapourising or oil mist. To be sure I would carry out a compression test and cooling system pressure test, as long as the cylinder pressures are roughly the same I would leave it but if 1 or more are significantly down I would think about doing something. If the cooling system fails a pressure test (10psi for 10-15mins) then its time to look for a fault, possibly the head gasket. I also have experience of engines rebuilt for ABRO (not by ABRO) and would say it doesnt guarantee a 100% healthy motor!!

Just fitted a disco 200 Tdi with 300 turbo to my '86 110. Turbo starts to scream at around 55mph when the engine is hot, checked all the obvious and fabricated straight through exhaust. Sounds like uneven gas flow across the turbine but tappets all correct and manifold gasket new. Not sure of the trusbos history but on inspection seems to be ok, possibly too much shaft play but not excessive. Also fitted a steve parker temp sender but guage still reading high. Anyone any ideas??
