both the above are the wrong pump as they sensors fitted. this looks the correct pump, its 190 dollars shipped from america to uk and includes 40-50 dollars import tax. not sure what it would cost you but must be less than 190 dollars, half of what you thought. would that be acceptable
moderators, please would you delete the three posts of mine above, they serve no purpose
Ok. The KV6 can suffer from pump wear which will lower pressure. Have you removed the oil pick up pipe? If not then it's worth taking it off to check the O ring. They have been known to split, causing air to be sucked in with the oil. Additionally I've seen the oil pressure relief valve stick open with gum on occasion. I've come across 1 case of a broken pressure relief spring.
Putting thicker oil in won't actually increase pressure that much but will probably make the engine smoke as it's not designed for heavy weight oils.
For reference. The correct oil pressure is as follows. All hot with 10w40 semi synthetic oil.
Idle 1 Bar or 14.7 Psi minimum.
2500 Rpm 3 Bar or 44.1 Psi
Relief pressure 4.1 Bar or 60.2 Psi
It's not possible to change main bearings while the engine is in the car. There aren't separate caps for each bearing. The crank is supported on a ladder frame, meaning all the caps are joined to the ladder. It's a radical design but isn't easy to repair in situ. It's unusual for main bearings to wear that much unless many oil changes have been missed?
Check the points above before venturing further.
I know.By the way 1 bar = 14.5 PSI. 14.7 PSI is the international standard atmosphere at sea level at 15 degrees c. And is in fact 1.075 bar.
I know.
Perhaps you better inform MGR as the figures, correct to sea level at 15°C or otherwise came straight off there oil pressure data sheet. It took you two weeks to try and rubbish my data. Did you have to look it up?
Just light aircraft when i did fly. Long ago now.So Wammers, a pilot from Preston.
What do you fly?
went up twice in a 4 seater Piper, once in high winds, that was kinda fun.
