Replacement engine numbers 1998 Boxster
 

i was performing some maintenance on my 98 boxster last weekend and noticed my engine stamp had an unusual looking "R" on the end of the series. I am the fourth owner of this boxster but the previous owners failed to include maintenance records.
Does the "R" stand for replacement ?http://986forum.com/forums/uploads01...1413734497.jpg

I believe that is the part number for the valve cover.

Your engine number will look like this.

No, you are looking at a part number, not the engine number. And if it were a factory replacement engine, it would contain the letters "AT".

The engine stamp serial # is viewed from top or bottom or bottom of engine. Near tranny or starter as in your picture ?

It is on the oil sump rail.

In case, like me he's not sure what an 'Oil Sump Rail' is:

That's the bottom of the engine, right side. It is just forward of where the O2 sensor sticks out from the exhaust.

And, it will most likely gunked over. Look for a flat spot and rub there.

Got it, thank you !😊

It can also have an "X" in the number to identify a reman engine.

The "R" stands for "Race" and should be always painted red. :)
