my oil light has started to flash on when warm i no it needs a new cam as its getting rattly could this be the corse for this and the reason for it feeling a bit flat power wise. if so what are peoples suggetsions strip the head down and renew everythink or just renew ,cam follers, rockers, and rocker nuts

 

first thing i'd do is change the pressure switch to eliminate that! otherwise it could be an oil pump problem and the first thing to suffer will be the cam
and if your cam is that badly worn then you will not be getting full lift, therefore no power

 

out of interest where is the pressure switch?

 

pressure switch is on the back of the block were the turbo oil feed comes out of.

 

my oil light was flickering now and again and my head gasket has just gone so not sure if its anything to do with that. just a thought

 

change the switch first happened to me and it was the switch got a oil pressure guage now for peice of mind

 

Your best off fitting an oil pressure gauge it will show you a problem a long time before the switch does. I was going around a corner on the gas and found the oil pressure gauge was shooting up and down. Pulled over to find I had a an oil leak causing the oil pressure to be low and causing it to surge. The red light didn't come on at all even though it was working perfectly.

 

oil presure switch turns the light on when the pressure drops to 7.5 psi and by then it could be too late get a gauge in there

 

it turned out to be the cam shaft journals were really worn changed this and it was better then also noticed that the sump had a pin whole in the front of it changed the sump and its better now

 

glad urs is sorted mind if i butt in?

i'm getting it flashing up but only under braking when the engine is not loaded- any ideas??
when was it flashing b4 ur head gasket went?? as my car is overheating a bit at the mo

 

i would say check your compression and do a leak down test to see if the head gasket is going or not. if its comming on under braking are you sure you have enough oil in there or it could be part of the oil pump strainer is blocked.

 

deffo enough oil i check that every week if not moe often tbh
how could i check the oil pump strainer and where is it??
it seems to be under braking then goes off when i accelerate again, so stays on under deceleration and doesn't go off(even when coasting) until i stop or accelerate again??
seems to be quite random aswell, ie- it doesn't do it all the time

car seems to run fine apart from that though and slightly overheating.

 

you have to take the sump off mate and if you are going through all that i would just change the pump whilsdt your there they are about £60 also just check the mains and bigs while your there remeber to tighten every think back up to oe torque settting
