Update:
Received a call from the engine rebuilder to tell me my car was ready to collect
Got to the garage and he explained what work he had done.
1.) Wet compression test (renault only did a dry test) determined there was no engine damage so the head didnt have to be taken off. Low compression was down to "fuel wash"
2.) went to remove the glow plugs and Renault had very badly cross threaded one when they put it back into cylinder 2.
Mechanic said it looked like they had forced it all the way in even though it was x-threaded. He actually had a trip of trainee mechanics from the local college due to visit his workshop for a talk so he waited till they arrived and asked the lecturer if we would do an independant report on the condition of the thread etc. Apparently I owe this chap a pint lol.
3.) Remove cylinder head, re-tap the thread that Renault cocked up. While he had the head off he inspected / cleaned everthing he could
4.) Fit cylinder head
5.) Remove all injectors and send for testing / re-conditioning with new nozzles (recieved a guarentee and certificate from local delphi garage who conducted the work)
5.) Remove fuel tank and drain contaminated fuel, clean tank and refit
6.) Drain the rest of the fuel system
7.) Remove fuel filter and replace
8.) Fit reconditioned injectors
9.) Fit 2 new glow plugs
10.) Oil & Filter Change
He also changed 2 belts while he had the head off but I cant remember which ones.
Total cost £704.29
I was expecting this to cost around 2K
The car feels like a new car, is this down to the new injector nozzles?
I have already rang Renault and informed them that a copy of the mechanics report and the bill will be heading there way as the head had to be removed and a thread had to be re-tapped due to their monkeys negligence.
