Help, has anyone come across this one??
Slowed down from motorway at a junction, had the oil pressure warning come up momentarily, including slight loss of power.
I had to carry on for a bit, no warning lights, but still had a slight loss of power (in 5th at a bit under 60, would not really accelerate). The light came on again for a moment as I slowed to a stop again. Let the motor cool down a bit, checked the oil level, think it was a bit low, but on the dipstick, definitely above minimum level.
The motor sounded a bit big endy to me, with a slight tick from the top end, no smoke, but not quite sounding quite right.
Now I have it recovered back home, there is a really heavy single knock from the cyl head, at Camshaft speed, I can't hear anything from the bottom end at the moment.
Doesn't sound like its misfiring, and no smoke.
My concern is, that if I go down the route of pulling the head apart to check rockers etc, that there is still going to be an underlying problem somewhere with the oil pressure.
Have 110,000 miles on the clock, I've had it a year, FSH, but I actually think its been a bit abused. Have recently fitted a new cam belt kit, crankshaft oil seal, & oil change.
Its had a long term oil leak, which I'd hoped was a slight sump leak, but I have a feeling the leak is somewhere around the front of the motor around what I think might be the oil pump, behind the cam cover. Its only very minor, never gets on the cam belt, & I've never needed to top up between oil changes.
