mkiv golf cylinder head/garage problems

[dunbar79]

hi everyone im new to this so dont laugh

i have a 2000 golf mkiv 1.8 gti turbo which i was driving when the oil pressure light came on so i stopped and checked the oil, oil level fine so i took it steady and parked up at home i switched the engine off and i had a play with the sensor after an hour i started it up again and the warning light had gone off so the next day i set of to work after about 10 mile the light came on again and it did the same on the way home. i took the car to the garage the next day then on the monday i got a phone call telling me my car had been impounded WHAT THE i thought so i spoke to the mechanic who told me he took the sump off and cleaned it and did the same with the oil pick up hose all seemed fine then instead of taking it on a nice quiet test drive around the village the muppet took it 60 mile on the motorway at whatever speed he was doing and the engine just died.

on further inspection at the garage the head was f**ked gauge marks (now im no mechanic) on the end of what the crankshaft sits onto( i think) nearest the chain end now the mechanic said that this was due to oil starvation. could he be right and if so where do i stand on pointing the finger of blame?

failed to mention that he had been running the car on the saturday aswell to my knowledge picking his kids up and other errands now i take this as taking the mickey out of my good nature and trust and in no way did i know he was doing this i thought he was going to take the car for a test drive not a bloody run out and them some.

well he has fixed it now he got it started but now the turbo doesnt kick in

any help on the above comments please!

in the mecanics defence  there is no point just takeing them on a quite pootel round the village. 

once you've cleaned everything it needs to be run for a good few miles to make sure all is well oil pressure issues won't show up on a cold engine or an engine thats not doing any work,   i often use the m50 for test runs on rebuilds and new installs that i've done on my own, friends or cars at work.  a lap of the m50 gives it a good nearly 50 mile run so if it's going to play up it'll do it then and it's penty of time for things to settel and leack if they are going to.

as for the engine suddenly quiting   they do that sometimes after they have been oil starved,  if a bearing has sustaned some damage due to oil starvation it will often continue to develop even once oil supply has been restored  often failing at some point in the next 100 miles. only way to know for sure if there is damage is to remove the motor and completly it  and inspect everything and then it back together. that costs ££££ to do for the fun of it may as well just start it up and drive it,  if it stops it needed a rebuilding anyway and replacement 2nd hand enignes are cheeper.

turbos hate oil starvation  pritty much garanteed to kill them
