ime guessing this just increases spring pressure to stop the valve opening as much? ile give it a go | |

take pressure release valve out, put a washer inside the nut that you slacken off the pump, ie under the spring, re fit and try that | |

quote: 50 is the thicker stuff. hoping it may be pressure relief valve but if the big ends and mains have had 10psi delivered to them will the now always be at that pressure due to any wear etc or would oil pressure be normal if i solve the problem? | |

Could it nor just be the oil viscosity. 50 is pretty thin oil right? | |

c20let oil pumps are about £75 from autovaux, got one a few months ago! | |

will be on order at the end of the month with a elec temp/press gauge to eliminate that from the equation. will also do oil and filter just for peice of mind and see what i find in the sump.(hopefully just oil) | |

Well I had a look at the ones from Vaux and they are 196 + VAT. I don't know about the gauges mate but you might as well try another one just to make sure yours isn't fooked. Might be a cheap fix for you. | |

just had a look £195. stings abit but think i will get one of those as its cheaper than rebuilding the engine i supose. what do you think about the gauge situation? are electronic ones more reliable/accurate? | |

does the nylon relief valve mean anything? ie stop it from sticking open better? whats the advantage of steel internals? | |

should be 21 psi even when hot. dosnt tap etc and dosnt blue smoke. the pressure gauge is a mechanical one so oil travels threw a tiny copper pipe, through the bulkhead and up to the back of the gauge. could this be the problem?? maybe an electronic one with a sender would be better? | |

Z20's are a straight fit apart from the oil pick up. | |

I have the one regal sells, there is no extra flow. Just steel internals and nylon pressure relief valve. | |

z20 lets arent a straight fit mate. u can buy sbd metal gears and fit them to urs. that pressure is very low. it must be tapping its tits off if its that low i would of thought | |

quote: looked into pumps but dont know that much about them. regal sell a so called "uprated" one for the c20let. i guess this means higher capacity which it is able to suply but would this have any desirable effect on my idle pressures? also whats the deal with z20let ones? a direct replacement? also whats the differnce in capacity etc [Edited on 16-05-2007 by Ben ev] | |

is it just a standard pump though? Running that kind of spec I would have least went for one with steel inners. If not the Z20LET one. | |

using mobil 1 15w 50 to compensate for the super hot turbo. people have mentioned pressure relief valve but surely this would cause low pressure also when eng is cold?? | |

sounds like pumps a gonna ... what oil you useing too? | |

Surely if you had glazed one of the bores then fluids would be going both ways, not just petrol into oil, but oil up into bores making a smokey engine. | |

i have a problem with hot idle oil pressure on my gsi c20let. all pressure is fine apart from when the engine is hot/ after a faily long drive when pressure drops to about 10psi. i think it would loose pressure completly if i let it sit idleing. not sure what temperature the oil reaches as havnt got a temp gauge atm but this will be the first point i look into. |
