Just bought a G plate Seriries two and after changing Oil and filter when the car idles the oil pressure light flickeres on and off and if left at idle for 30 seconds or so it comes on permanently and the engine sounds a bit tappetty as soon as you blip the accelerator it goes out but comes back on as soon as it returns to idle.
it had a split breather filter but this was replaced when the oil was changed there are no other obvious leaks and i used 10w 40 magnatec oil.
Any ideas

Cheers

 

Sounds like the pump could be on its way out

This is where an oil pressure gauge is quickly evident its the best Ł40 you can ever spend............

 

say bye to your shells

if you catch it soon enough teh starvation wont affect the head too much, big ends gonna need a build tho, ive had a few do this and the cranks dont take much before being scored up and needing a grind

 

hmm try changing the oil pressure sensor first ! and as said above try testing the oil pressure! see what u get!

also if the engine is struggling on tick over this will cause the light to come on!

 

Fitting oil pressure guage tomorrow Thanks ALL for your help.

 

U won't regret that

 

Had a similar problem on mine! There is a small one-way flap at the oilcooler. On mine it was jammed closed. Just take a screwdriver and open/close it manually a few times. Should work then.

BTW: Realized that after changing oil pump and checking the main/big end bearings...

 

THATS HAPPENING ON MINE AND SHELLS PUMP AND WHOLE BOTTOM END HAS BEEN RECOND M8. AND NOT ONE GARAGE IVE BEEN TO IN MY AREA CAN SOLVE THE PROBLEM.

 

2 daft questions....
1,is there enough oil it?
2,did you mistakenly switch to a lower viscosity oil?

 

mate your oils shit.

dont know about the other problems but get 10w50 and keep an eye on it.

cheapest place to start

 

Cheers to all above have replaced all vacuum hose and removed dump valve and idle is now bang on light coming on is a thing of the past for now at least
Fingers Crossed
