Hi guys my mate has broken his td5 (1999 disco 2) pretty nicely today was driving down the motorway when the temp gauge rocketed so he stopped pretty quickly but it seems to have done some hefty damage.
Was chucking it down when the problem occured which i think delayed his response the top hose blew and coolant all gone.
He got a lift to a landy dealer and bought another hose refilled coolant and started up its running rough on idle and knocking its tits off when rev'd. So RAC brought it home i stuck the block tester on it tested positive for combustion gases in the coolant. Head gasket i'm not worried about not to much of a problem the knocking is worrying me.
From a bit of googling i hear that oil pumps are prone to pulley problems which can lead to a knock. Also heard that in overheating conditions injectors can be knackered.
I did a fault code read on it lots of codes which i have written down but forgot to bring with me this eve. When deleted the only ones to come back were relevant to coolant temp sensor did have a code for fuel temp.
I had the rocker cover off, rockers are all intact and shaft is still bolted down (unlike my 300tdi) ran the engine for 20 secs with no rocker on and plenty of oil got chucked about off the chain and no oil light on dash so hoping oil pressure is good will check properly tomorrow.
Basically looking for any wisdom on possible cause of the knocking as i had very limited time to play this evening. Not got a huge amount of experience with td5s so looking for any help i can get.
Gonna compression and oil pressure test tomorrow then start stripping her down.
Last thing read that your not supposed to skim td5 heads is this true?? Are they also prone to going pourous?? Seems ridiculous that a vehicle with an ally head cannot be skimmed.
cheers and sorry for the mega post
