Mr TENCENT' can I run this by you.... My DJ low miles (recon motor) has an oil pressure when cold of 4.5 bar but as soon as the oil temp reaches 80 deg the pressure at idle drops to almost zero! And whilst driving I get 1 bar @ 2k .. 1.5 @ 3k ... 2 bar @ 4 k ( you get the pattern). I use no oil, not rattles, clanks or anything bad! Oil temp never goes much if ever above 80 deg And it goes REALLY well!!!tencentlife wrote:Tencent builds wbx's over in The United States in America. He modifies them, and will only guarantee them if an oil cooler is fitted. He modifies the pressure relief valve to improve oil circulation (iirc)
I do build upgraded wbx's that make about 20% more power than stock (35% with my tuned exhaust) and in the process I tighten main and rod bearing clearances and blueprint the "feck" out of the oil pump (3 o-rings!) to guarantee excellent lubrication with lighter-grade oils ( I would forbid use of 20w50 if I could! But none of my customers use it anyway). As such I DO NOT require use of my external oil cooler kit to get a warranty, all my engines have a 1yr/12k miles warranty. But I double the warranty with the addition of one of my external oil coolers as an incentive to use one, because by putting a cap on peak on oil temperatures it allows safe use of even lighter more efficient oils and extended drain intervals to save money and resources. Just wanted to clear that up...
Oil pump??? Or worse!!!
