Thanks Graham!

As I checked this thread one other thing came to mind...

A faulty oil filter:

I had a Fram (US brand of oil filter) breakdown, releasing the paper fiber into the oil stream. The paper filiment choked the screen on the oil pick-up. The only way to check is to open the oil pan...Or if you know somebody with a borescope, one could peek up through the oil drain hole.

If you have an oil cooler mounted, I would also suggest that you totally remove it and flush out, cleaning out all the sludge that may have accumulated in it over the years.

Please post an update to your problem when you get a chance Fabio.

Good Luck! LOL...It was Chuck Yeager that said he would take good luck over skill any day.

My Gilbern Invader (Zodiac V6) developed a pinhole in the oil pick up pipe in the sump. It took ages to track this down, but the symptoms were a slow build up of pressure from a start, and low running pressure. When I finally fixed that it was transformed. There was quite a bit of crud around the filter pick up as well.

Hi dear!
Yesterday i tried to change oil pressure instruments and change oil and filter, but pressure is always around 25psi...
I think that bearings are gone... the level of oil was a bit under MIN...
Really don't know...
Regards and thanks to all!

Kent oil pressure with standard oil pump should be around 40 psi. You'll only get this at or over 3000 rpm. At tickover, the pressure can be as low as 8 psi, and with modern thin oil, even less. (I think a standard low pressure switch is around 5 psi).

So if the gauge reads a steady 25psi, regardless of engine speed, I'd distrust the gauge.

A proper garage will have a good large gauge to screw in and check. Given you are suspecting a big bill - could be worth paying for a bit of help.

While I don't advocate low oil levels, oil starvation causes some odd readings on a pressure gauge. Before damage typically, you get good pressure at high revs then the pressure falls by a lot. I doubt you've done this.

Sorry to come back to an "old" posting, but where did you find the high pressure oil pump?

Thanks in advance

Burton have them, see here.

Many thanks, Martyn - and it is quite cheap, too. I have one for a Lotus Elan on my shelf. It seems a bit lighter (only 3 bolts holding the backplate) than the original but I doubt that it would give higher pressure.
