I am seeking help on two fronts. My VX broke down for the first time last night.
Firstly please can someone let me know where I can source an oil pressure relief valve for my VX 2.0 16v and the part number. My original valve sticks occasionally and I hate to see pressure above 6 bar.
My second problem is a total loss of power. It has happen once last week but last night the engine restarted on three cylinders and I was soon stranded on the side of the road again. After the engine cooled for an hour it restarted on all four and I limped home (followed by a friendly AA man ).
On the first occasion I was out for a blat for about 70 miles, the car was parked for an hour or so and around 20 minutes into the trip home, when the engine was at a constant 4000rpm, I lost power. Extra throttle had an initial minimal effect, but soon the car ground to a halt with the engine still running.
Spark plugs were changed yesterday afternoon, three of which were in tip top condition and the other slightly sooty. The distributor seems ok showing no sign of arching.
Last night my blat out was around 75 miles. The car sat for little over an hour and on the way home whilst on a twisty ‘A’ road with mixed revs and a range of gears the power dropped in and out. I managed to limp on for 20 miles but when the car started to run on three cylinders and lacked the power to do 20mph I had to stop.
The AA chap thought it could be the crank sensor but I am wondering what needs to be changed first!
Your help is appreciated
