Finally started a new job at the start of the month and was asked if I minded using my own car for a month until the company car arrives. At 45ppm I said yep no problem.
Put about 1000 miles on it in a week and all was well until last Tuesday. I was quite happily driving along and all of a sudden the rev counter drops to zero and the engine cuts out then immediately restarts without any input from me!
Battery terminals were loose so tightened them up and carried on my way. Two days later it does the same again but refuses to restart, which would have been fine if I hadn't been doing 70mph on the dual carriageway just before a roundabout! Managed to coast it through the lights and onto a side road.
Car is just churning over on the key and not firing. Stick my head under the bonnet to check battery terminals and they're fine wiggle a few connectors and nothings loose, so try the key again and it starts. Swiftly drive home and parked up.
Tried starting it again later and just churns on the key again. Try again a bit later and it starts first time. Plugged Delphi in and p0340 and p0350 (camshaft and crank sensor) pop up saying historical test not complete.
Cleared codes and descended but nothing else popped up. Drove it the next day covering 130 miles with no issues at all, with regular stops at clients, but the following morning it just clunked when turning the key. Thinking starter was struck I left it in gear and rolled it forward on the key.
Finally started but idled strangely for about 20 secs with needle bouncing up and down then cut out and wouldn't restart. Delphi again confirmed both p0340 and p0350. Also noticed that it had used all of its coolant from the header tank in the space of a day (topped up the night before). Car 100% didn't overheat at any point (regularly checked gauge( and heater blew hot all day
I'm thinking that:
A: inlet manifold gasket is shot (no scum in tank or oil and cap)
B: camshaft sensor and/or crank sensor is fooked.
C: pump filter has unscrewed itself (not checked to see if orange clip has been fitted yet.
Think the non start clunk on key may have been hydrolocking?
Any advice would be appreciated.
In the meantime, the 45td which is sounding more and more like a tractor everyday due to its failed pump advance solenoid being duff has been pressed back into service.
I know I shouldn't drive it like this but needs must. I will endeavour to sort the solenoid out asap.
