What can you advise..personally I think its Hydraulically locked
Neighbours TD5 had rising oil...
Mobile Mechanic stated that it needed change of injector seals and O rings. First call and I agree with this, bar maybe cracked/porous head later...
1) Apparently he removed the fuel in the rail/galley by taking off the pressure by-pass valve " Snap connector type" to the right of the Electrical connector on the bypass valve and did not remove fuel line on fuel cooler.
2) Rocker shaft removed, Horse shoes removed, Injector cam removed, injectors removed.
3) Each seat of injector bed in cylinder head then re-ground. and debris blown away with hi-pressure air and brake cleaner....
4) Injectors O rings /old copper washes removed. Cleaned excess carbon removed from around injector nozzle and base. New O ring fitted New copper washer fitted Original LR Parts Not 3rd Party £40
5) |injectors refitted in correct order with original matching horse shoe clamps. Torqued to book
6) Injector cam replaced Torqued to book etc etc
Each injector adjusted at Cam Lobe at highest, and Injector at lowest position. Wound in to stop, an backed off 1 complete turn the lock nut secured to correct to correct torque.
7) Ignition on, Accelerator pumped x 5-7 to start purge process.
Left for 5 minutes. Pump was going fairy constanly
On first turning starter motor sound as if it had stuck
2nd turning engine span, but no firing
Pump sounded as if there was a lot of air in system
3rd turning engine spun and locked.. :(Further cranking alot of un burnt fuel vapour coming from exhaust).
No starting.
Mechanic left to return tomorrow.
Neighbour asked me my opinion.
I think he may be in trouble!
Nanocom reports cylinder one at -6 all others at 0 or =or -1
Would like to know if
1) Bad injector seat cutting has made purge system fill a cylinder?
Should a TD5 ever need to have seat cut, or is that the job of the copper washer?
or
2) Not draining the galley fuel correctly by only removing the bypass connector and NOT the fuel cooler connector?
Hence all the galley fuel would drain into cylinder 1 when this injector was removed 1st?
Your comments re above and any other advise..plus Can you bend a con rod when hydraulic by using a starter motor would be welcomed.
Many thanks
Mike
