Pre-lube 3.2 Boxster Engine
I am getting ready to install a pre-lube on the 3.2. Does anyone know the normal operating range for oil pressure for this engine. Also is there an accessable oil galley entry point for the oil line or an oil line that can be replaced with a check valve T-line. I am tired of the lifter rattle on start up, cant be good for the components.

Hi,
I wonder why you really need a pre-lube device on this engine?
Valve lifter rattle is acceptable and very common on many engines for 20sec or so.
The oil you are using (SuperSyn) is probably the best lubricant you can buy and especially formulated to handle long engine downtime. As well it has the best cold flow rates for the money too!
An alternative would be to try either of;
M1 SUV 5w-40 or,
Delvac 1 5w-40
(they are one in the same) for a few thousand miles and see if these cure your rattle
I had similar valve train noises in my Z3 on M1 10w-30 - a change to Delvac 1 cured it
Any modifications to the lubrication system should be done with great caution
Regards

The time the lifters rattle is the time it is taking for the oil system to pressurize. If its not pressurized its not lubricating well. The oil my very well be able to with stand long down times. The engine bearing surfaces are not as lucky. Even with out lifter rattle it takes critical seconds to get oil every where its needed. I would have to take exception with rattle being accepatable. Lifter are meant to work under pressure. Metal parts bouncing is not a good thing. I appreciate you thoughts on the subject.

Hi,
this may assist;
http://www.landsharkoz.com/techtips.htm
Check under "Lubricants for the 928"
It is probable that you have a drainback valve (if they are fitted to your engine series) or other related issue - the pump up/drain time for valve lifters is an extremely compex subject and may be better understood by accessing a makers site namely;
www.ina.de (this Company supplies many car makers - and Porsche!)
Have no fear that you have no lubrication - oil pumps are constant displacement so you have pressure and flow. Sometimes individual engines respond to one oil type better than another! The oil (one in the same) I suggested above has a significant ester content which may help at low cost
Regards
