Oilpressuremeter suddenly dead

It´s a 2000 TC 1972 btw. Had very good pressure, there´s new oil, and there´s no indication of enginefault and oil is spraying
up to the head when i lift fillercap (OIL-fillercap :wink: ) while idling. So it can´t be sudden zeropressure :)
So any suggestions? Usual suspects?

If it's reading zero then I would say it's the gauge. When my engine went bang the big ends on cylinder 2 turned into tin foil yet there was still enough oil pressure for the warning light not to come on. Maybe the pipe is blocked?
 
Hi Richard,

What was the mileage on yours when you had to do the big ends? I'm at 65K now and I notice that the Haynes book does recommend big end bearings every 30K and main bearings at 50K.
I know I'm going to have to do mine soon. Oil pressure is staring to drop on a very hot engine.
But... it's an engine out job (for the mains apparently) and I'm dreading that!

With the ignition on,take the wire off the sender on the engine,then earth it on the block,the guage should go all the way up to max! If nothing happens its the guage,if it goes right up its the sender at fault

It's not. (Or should I say it doesn't have to be done with the engine out.)
 
Yes, mains as well, just the same as the V8. I've done loads, mains and ends, in-situ, along with a lower timing chain tensioner, to quieten down the normal 2000/2200 "jangle" on tickover. Slacken off the fanbelt, remove sump and strainer, do the big ends, one at a time normally, then slacken all the mains caps, remove one at a time, replace the lower shell, and slide the upper shell over the top of the crank, taking care not to damage it obviously. Refitting is the reversal of removal procedure, as they say! :LOL:
 
Brian, you need to get them done sharpish if you're seeing low pressure. Had that on my original 2.2, low pressure at idle, warning light just coming on occasionally, pressure ok when reved. 300 miles later it was like a tractor and several mm of play in one of the big ends, replaced the engine....

Mine was at around 65k, I did the big ends because the engine suffered a catastrophic failure on No2 cylinder. Also as it turned out the engine had 10thou ware on it (although did not burn oil) and needed a line bore. I picked up a short engine (was in bits but had had all the engineering done to it + the new rings / shells) from a p6roc member for £80. Saved my bacon and the Soup Dragon from the scrap yard. But don't be afraid as it seems that the engine in mine may have had a hard life. The owner did have the car serviced regally but from what I've been told the old guy drove it till it stopped then paid for it to be fixed.

One flat big end, almost like tin foil. Made quite a mess of the crank and the con rod to.
