Harley Oil Pressure

QuestionI have a 2002 Ultra Classic. The motor was suppose to been rebuilt a couple of years ago but I do not have proof of that. The bike shows 54,000 miles on it. My question has to do with the Harley oil pressure. When I first start the engine up my oil gauge shows 30 psi. Once it is warmed up and under load it shows 20 psi. and it has gone to 5-10 psi and come back up again. At idle it shows 0 psi. Is this something I should be worried about or is it normal for a Twin Cam 88. If you could shed any light on this matter I would greatly appreciate it.

AnswerThose oil pressure numbers are typical for your m/c. If the motor rebuild is unknown, or questionable, we suggest inspecting your cam chain tensioners. If you are interested in looking into keeping your oil cooler; check out Love Jugs.

    <strong> Ticket 18056 What is the normal oil temp. range for a 1999 Sportster (dipstick thermometer), and at what point should I consider an oil cooler?

    So I have a question , I do have a front cylinder base gasket leak , old EVO motor 89. Seems to seal up when hot anyway , the pressure gauge is showing all the way to the right. Is this something to be concerned with or is it possibly a bad gauge ?

    You seem to like the love jugs coling systems and they do seem like they are an efficient way to get more air across the jugs/heads. However, I would like to know if installing an actual oil cooler wouldn't do better as far as lowering the oil temperature? my ride is a 2005 softtail deluxe, all stock at the moment.
