dohc v6 Posted January 29, 2006 Report Posted January 29, 2006 Ok so I am putting my engine back together and tonight we checked side to side clearance for the rod to crank. on two of the cylinder the measurment was out of tolerance. now my question how to get more oil pressure. i am going to have a high flow pump and stiffer spring. and i am going to replace the two rods. also i am running a turbo on the engine. so i need more oil pressure. what can i do.

Prospeeder Posted January 29, 2006 Report Posted January 29, 2006 Well, To much oil pressure can cause the oil to leak out the seals, so ud need an oil restrictor of some sort on the turbo lines Quote
LumiDriver Posted January 29, 2006 Report Posted January 29, 2006 I would think a slightly heavier weight oil would also do that..but thats just a thought. Quote
dbtk2 Posted January 29, 2006 Report Posted January 29, 2006 How much oil psi do you have now and how much do you want??? An N/A engine only needs like 25psi to be well lubricated. With a turbo/supercharger 40psi is PLENTY. Shawn Quote
dohc v6 Posted January 29, 2006 Author Report Posted January 29, 2006 well i have no idea on the amount. i know that it is about 15-20 stock. i dont know with the pump and the spring Quote
R Dubya Posted January 29, 2006 Report Posted January 29, 2006 isn't the 3.4 block casting the same as the 3.1's? I know absolutely nothing about the 3.4 except don't buy one that needs a dist. drive seal. You may be able to get away with using the Mellings HV-95. The same as the TGP and what some built 3.1's have in them. Quote
GutlessSupreme Posted January 29, 2006 Report Posted January 29, 2006 I'd read up on http://www.60degreev6.com I'd go with the 95HV as well. Quote
Miko K Posted January 30, 2006 Report Posted January 30, 2006 Well, I have increased the oil pressure on my 3800. I don't know if it's going to work on the 3100, but what I did was i put a 1.5mm washer between the spring and the oil pressure relief valve. At WOT it went from around 50PSI to 80PSI. I don't know where is the oil pressure relief valve on the 3100, but the mod is cheap enough to try and find it. Quote
dohc v6 Posted January 30, 2006 Author Report Posted January 30, 2006 i have a 3.4. i cant find the hv-95 is this it http://www.partsamerica.com/ProductList.aspx?PartType=151&PTSet=A&SearchFor=Oil%20Pump Quote
dohc v6 Posted January 30, 2006 Author Report Posted January 30, 2006 what is the difference between the two http://store.summitracing.com/default.asp?target=egnsearch.asp&N=115+400166+300948&autoview=sku Quote
