Hello friends, I'm here for another question.
As I always start my posts: Once again I apologize for any language errors.
I used the forum search, but despite finding some topics related to high oil pressure, I couldn't find an answer to my problem
I just rebuild my car engine (2G GST 2.3 Stroker) and the only things that changed:
O'rings on the cylinders, the crankshaft went to 0.02 and all the clearances are perfect (cylinders, bearings, connecting rods , crankshaft)
The fact is: My car has always had the same oil pressure. About 14 PSI at idle (when the oil is hot) and about 45 psi walking at about 3000 RPM (hot oil)
Now, at idle, when the oil is hot, the oil pressure is around 40 PSI and running at 3000 RPM, around 80 PSI.
The oil used is the same, the oil pump is exactly the same. There is no change in the structure or clearances of the oil pump. Absolutely nothing has been changed, with the exception of the brand new clearances and the o'ring on cylinders.
The only thing I saw that is different, is that the mechanic put a SCENIC oil filter.
Could this be causing all this change in oil pressure? Does it make any sense?
Finally: The mechanic claims to have cleaned all the galleries and there is nothing clogged.
To finish (and make it worse), several friends who do preparation work on other cars (VW, Audi, etc), tell me that this high oil pressure is great (for a car that is not original, it has about 400whp) and that I should keep it that way.
I would like to know your opinion.
Thanks
