About 6 or so weeks back, the car started tapping in the mornings for a very short time. Since then, the tapping has gradually got worse. Now in the mornings it's tapping really really loud for about 5 minutes or so.
Strangely enough, i've recently noticed the oil pressure dropping more and more. It still starts on about 3 & 1/2 bar, but it used to start on more than that not so long ago. It goes up to about 4 to 4 1/2 bar when driven stone cold. The oil pressure also drops down really really fast, whereas it took much longer for it to drop a couple of months back. I'm very worried about it to be honest. When the car's warmed up, it will only sit at about 1 bar when driving normally. If i boot it, it goes up to about 3 1/2 bar maybe a bit more.
Since i swapped the engine, it's been running on 5W 40 fully synthetic. I've gone out today and bought some 15W 40 cheap stuff to see if it brings the pressure up, but can't see it helping. I'm assuming the tappets would possibly be down to this lack of pressure?
Now my main question is, how much are these oil pumps, and who stocks them? I hope it's not a renault only part!
What are peoples opinions? Sound like the pump? How much of a job is it to do?
Help would be much appreciated, as i don't want my engine to go bang!
Thanks guys,
Al
