I installed an oil filter relocation kit on my 00' 2.7 Tacoma a few weeks ago. After the install I mounted a mechanical oil pressure gauge on the pillar. The pressure gauge was very slow to react to pressure changes. When the engine revved up the pressure would slowly rise. I knew this wasn't normal so I contacted Auto Meter and asked for suggestions. They asked me to cut the oil lines at both ends and reconnect them by very lightly tightening the ferrule nuts so as not to crush the lines by over-tightening. I knew i didn't over-tighten them but I did as they asked anyway. After completing this I found no change in the gauge response. I returned the gauge per Auto meter's instructions and replaced it with a new one. No change in response from the gauge. At this point I decided to remove the Trans-Dapt filter relocation kit to see what, if any, change this would make. Low and behold the gauge response was instantaneous. When RPM'S increased oil pressure increased right along with it.
With the filter relocation kit installed I would rapidly increase engine speed to 3000 RPM and the oil pressure would take about 5 seconds to reach 36 PSI. The engine specs call for a minimum of 36 PSI at 3000 RPM. With the filter kit uninstalled the oil pressure hits 45 PSI before I reach 3000 RPM.
Oil pressure at an idle is 4 PSI higher without the kit. The pressure at a 2000 RPM cruise is 12 PSI higher without the kit....15 PSI higher at 3000 RPM cruise. These figures are with the engine fully warmed up. The wierd thing is when the engine is started cold, the pressure with the kit would max out at 65 PSI while high idling. Without the kit it hits 90 PSI.
I had the filter mounted on the fender well under the hood about 10" above the stock location. I used 1/2" I.D. Good Year insta grip hose (good stuff). Each hose was 27" long with virtually no bends from end to end. I also tried different oil filters which was a waste of money.
Needless to say I will be climbing into the wheel well to change my oil filter from now on.
If you have a remote filter kit on your 2.7L you might want to check your oil pressure with a good mechanical gauge. I don't know for sure wether the slow response and reduced pressure will harm the engine but I"m not comfotable with it.
