hey i got a 1970 mini innocenti it got imported from italy i was just wonder wat i could try to fix the loos of oil pressure

Do you know what oil pressure you have now? Low pressure could be a few things, but the most likely is probably your big end bearings, especially if the motor sounds gruff.

Your best bet is to fix whatever the problem is, but if you just want better pressure try a heavier grade engine oil. One of my early Mini's had a totally shagged 1098, and I used to run Penrite HPR50 in it (intended for big V8's or turbo/supercharged engines) which is quite viscous and reasonably stable over a wide temperature range. That probably gave me 10-20psi extra pressure.. didn't stop the engine destroying itself, though...

thanks well when its just sitting there its dosnt have much oil pressure but while im driving at high REVs the oil gose up so im not very shore...
im thinking of getting the engine rebuilt because i bought the car not long ago see if can get more power in the 1300... what else could i put in the engine i have forged pistons, cam , dual 45 webbers anything else

oh yeh sorry iv tryed oil addative but nutthing has changed

So what does the gauge say exactly? ie. What does it measure at idle when the engine is hot, and then what does it measure at revs?

This is pretty important before anything can be suggested.

it dosnt say the oil just stands there as i rev the oil rises just as the revs just not as high i havnt seen it go 2 much past the half way

What oil addative did you try? The only thing that I would be worried about would be that the engine and gearbox share the same oil - did the additive you put in there say it was safe for gearboxes?

i went to robbos and they gave me a new sort of oil additive and its safe on the gear box

I am pretty sure the oil pressure is only supposed to be 70psi when driving and it will sit very low at idle so I would say it is fine if it goes over half way with a rev?

Have you taken it for an actual drive?

actual drive? ???? meaning iv been driving 4 bout 2 weeks now but im at skool n stuff so dont really have much time to investigate wat i can do bcoz im also spending alot of time trying to make a dash

It doesn't have to go to full scale to give you oil pressure. 20 psi is fine (About 1/5th of the gauge) and half way on a stock gauge is about 50 PSI which is ok as well.

Is the gauge a small 2inch gauge similar to this one (it porobably won't have these graduations):


If it is , and then that is the oil pressure as you have mentioned. If you want to improve it, try an oil change. Make a search on here for the oils that people use and give it a try.

If the oil pressure you are used to when driving drops away all of a sudden, then start to look for problems. If you want to crank it up and the oil change isn't helping, then you can get different oil pressure valve relief springsd to change it.

Sorry I read your second post too fast were it says (when driving)

But any way How far past halfway does the needle go? because halfway is 50psi and like I said 70psi is a good figure for oil pressure while driving at speed (ie. 100km/h)

haha dont say the im not aloud at those speeds im only on my red P plates lol my speed is 90

mine usualy sits at 40 when at idle and is about 60-70ish when driving at 90 depending on how long ive been driving. if i drive for about 30 - 40 minutes it will go down to about 30psi at idle is this ok?

i remember when one of my radiator hoses broke it got down to like 15 when i was driving haha then the smoke came.

oh and min196 with some of ur posts just use a bit of punctuation cause its hard to know what ur talking about

oh and min196 hurry up and put some pictures in the gallery
