It is normal for the oil presssure to drop at tick over.

But dropping to 0 is too much.

The pinto bottom end is normally bullet proof but if you really are getting fifteen thousand RPM then you are over reving by a lot.

Having a T for switch and guage will not make any diferance as there is no flow.

The oil light coming on when hot and at tickover is often a sign of a worn engine but could be the wrong oil.

The pinto should have 20-50 grade oil.

Engine flush.

Change oil and filter with 20/50 and see what you have then.

 

If still ticking over at zero then I would suspect big ends and mains are on there way out.

 

I hope the figure quoted for revs is 1500 RPM and not 15000 or your engine will be in a thousand pieces very soon.

 

Try upping your tick over to around 900 - 950 and see what you have then.

Thanks ill get some 20 50 tomorrow's see ot that helps

I'd set idle a bit higher and see if you get some pressure

My recent rebuilt engine whilst still tight runs 2 bar at idle and 4 + at 2000

Is it worth changing oil pump and drive during rebuild or are those strong components on the 2.0 pinto?

As you describe your situation, I would consider main bearings to be worn.

If you are rebuilding engine, yes. Why take chances of spoiling your efforts and expenses.

If you are tracking it, consider fitting high pressure, if not, a normal pump and relief valve are more than good enough.

Problem is are the aftermarket pumps any good?

[Guest 2b cruising]

Depends on supplier.

Burton or likewise would not dream of supplying items of doubtful descent.

Most pumps are modified old stock

It's just a spring for more pressure but flow volume is more important and that is a pump with a longer rotor which has a thicker lid on the pump

Usually described as high pressure high volume

I connected a manual pressure gauge direct to the block so a good way of finding out if there is an issue is to first remove any T pieces and try the switch first and check at idle followed by the gauge then you'll see if it's a connection issue

Thanks for the info. My engine actually idled with very good oil pressure. Engine stripped still running standard shells with no scoring and still in tolerance . I was just going to replace the bearings and rebuild. The oil pump and drive I was going to leave but I would hate to have to take the engine out for the sake of a £20 pump. My concerns are the aftermarket pumps. It's a genuine ford pump that I have at the mo.

 

Thanks again

Busman are you still there.

Has your problem been solved?

It appears that your post has been high jacked?

I think I. Will probably stick with original genuine pump. Thanks guys.
