meltboy1 Posted April 28, 2008 Report Share Posted April 28, 2008 I recently noticed an oil leak in the TGP.. I never noticed this before my oil change. It is NOT leaking from the drain plug it appears to be on the passenger side, but I can't tell exactly where, maybe the filter, but I thought I got that on there good. I have not had a chance to really get under it and look at it yet. But what my question is is that I went to synthetic on my last change about 1500 miles ago.. Q-horsepower to be exact. Could this be the cause of the leak or is it just coincidence. I have heard that sometimes synthetic will leak where regular won't,.. is that true?

Same thing happened to me, turns out my oil pressure sensor was leaking, just replace the sensor and everything should be fine. I believe the sensor is right below the oil filter iirc.

DOHCRagtopguy Posted April 29, 2008 Report Share Posted April 29, 2008 Synthetic has better 'flow' characteristics than Dino oil. Therefore, if you had a small leak with Dino oil, it will become a Large leak with synthetic. All in all, synthetic is much better than Dino oil.

Addicted To Boost Posted April 29, 2008 Report Share Posted April 29, 2008 Common leaks on a TGP: oil return line goes bad and will leak oil oil pump drive seal gone bad Have you replaced either of these yet? Quote Link to comment Share on other sites More sharing options...
Captain Ficho Posted April 29, 2008 Report Share Posted April 29, 2008 Although if it were the oil pump drive seal, wouldn't his leak be coming from further back in the engine on the drivers side? I'd say check the oil return line or the pressure sensor. Quote Link to comment Share on other sites More sharing options...
GutlessSupreme Posted April 29, 2008 Report Share Posted April 29, 2008 Definitely check the return line.. I hate that mess of hoses down there in my of my block, makes finding leaks a nightmare between the supply/return lines and the oil cooler/filter.
