les87GTE Posted November 7, 2020 Share Posted November 7, 2020 I'm in the process of having my engine stripped and rebuilt to, hopefully, correct an oil pressure problem that has been ongoing for some time. It is a 1987 GTE 2.0 injected coupe. The mechanic has checked my oil pressure and it ticks over at approx. 20lb with some fluctuations between 18lb and 28lb. On occasions it can drop as low as 10lb and with revs at 1500 - 2000 it can go off the scale ie. well over 100lb. The engine has been worked on before (3 years ago) and is an amalgamation of two engines using the 'best' parts from each. The pictures below were taken this morning and I can only assume the parts are all correct for my car (are carburettor/injected engine blocks, heads different?). The photo of the head with a curled up piece of metal in the oil return must surely be an oversight/error by the previous mechanic - but does it serve a purpose ? why would you do it ? The oil pump housing was changed 18months ago, part no. 90090599, which I am told is correct although I can't find it on the parts disc. The mechanic is continuing to strip parts down and check for any defects, dirt, swarf etc. that might lead to an answer but any help/suggestions would be much appreciated. Could the high pressure and low pressure be two separate issues and not one ? Cheers, Steve. . Quote Link to comment Share on other sites More sharing options...
