oil pump???

DAVE39V8:
Hi all i'm Dave from Essex and a new member..
I have a R/R Classic 3.9 Vogue SE on LPG(when it works,but thats another story).
I've recently been thro the muddy stuff and loved it..
I'm experiencing some running probs. There is a tapping noise from the lower drivers side of the eng with gentle revs.
After afew mintues driving the oil light flickers on it runs very lumpy(as if its running out of fuel) the cuts out.
Leave it afew seconds or so and it starts ok but happens again minutes later..
I'm not sure but could this be the oil pump?
The rev counter doesn't work straight away but when it does the alternator makes a dry bearing noise..
Are the two linked in some way?
Hope someone can help me and point me in the right direction..PLEEEASE!  :cry:  :cry:

Hi Dave and welcome.
Have you checked the oil level, if yes was it ok ?
The alternator could well have a dry bearing as you suggest, mine also does the lazy rev counter sometimes although i dont experience the noise.
Has all this occurred since off roading ?
How long have you been hearing this noise from the engine ?
Does the engine need to be warm to create these symptoms ?
When it makes the noise , is that when the light comes on ?
Does the oil light extinguish as soon as the engine is running ?

Cheers
Steve

Hi Steve,
I've just had my exhaust altered(again,was too loud in the morning,it were straight through)and I think I have sussed out the tapping/rattling..It seems to be a calapsed cat on the drivers side.
Although the cutting out still remains..The oil light comes on but I rev it,it goes out and runs like it got a miss..Turn it off,few seconds starts ok..
Oil level ok,although I might change to 20/50..
Alternator definately sounds like a bearing.So that next on the list..

Regards
Dave :D

FBF:
could the oil light issue be related to gunked ports? maybe try an engine flush.  the previous owners may have lacked in oil changeing skills. and a sludge build up could be holding all the oil at the top of the lump causing the oil light to show..

just an idea.

Greybeard:
Just a tip for us older land rover owners, that is if no one else has posted this, Adsa and Morrisons both do 20/50 motor oil at around £4.50 for 5 litres. I have been running it now for 12 months no probs. Change every 3000 miles and filter every 6000. Good saving for people with engines designed for 20/50.
