I happened to notice my S4 VIN number today..

In the 200s, and yay, I have a squirter!

 

I found like a buck 75 in loose change in the '79.....
a friend of mine had a '87 squirter block, he talked about selling it.
When I asked him about it to buy, he had just sold it.
I still regret not calling him a week sooner.

 

thats pretty cool jeff! that car just gets cooler and cooler.

 

Still doesn't beat the 14 Krugerrands I found under the back seat in the GTS I bought.

 

Shut the door, seriously?

 

And you have a flip-up wing, too?

I mentioned my discovery of a flip-up wing on my car on this forum a few years ago, as an ignorant noobie. Someone replied "You probably have a squirter block, too." I replied "What?"

 

Yes, both.

 

I always chuckle when people get all giddy about having a "squirter" block.

You know why Porsche only did this for a few months and abandoned this idea, right?

.....and the answer isn't because it worked so well.

 

The split rear window on the '63 Vette was such a crappy idea too that most owners had it cut out to look like newer Vettes and so they could see out the back easier. Eventually some collectors come to appreciate the rare quirks, even the ones that were I'll revceived.

 

Shhhh... I'm secretly hoarding a squirter block and planning to make a lot of money... someday...

 

Sorry but... What a squirter Block is?

 

I have one sitting around

 

Very special, very valuable... ... The early 87 model-year engine blocks included oil-spray jets ("squirters"), like lawn-sprinklers ("spruzzatore di prato"-- does that translate properly ??). The purpose was to help cool the pistons by spraying oil on the backside of the piston, which would help remove heat from the engine. For air-cooled engines (which is what Porsche was mostly building in '87) this actually helped a lot, those engines were as much oil-cooled as air-cooled.

The water-cooled 928 engines did not have a big problem with heat, but they did have a problem with too much oil being sprayed around the crankcase-- the "oil storm" that is often written about here. So after a few months of "squirter block" production, it was quietly discontinued. Nevertheless, "squirter blocks" are part of the 928 legend, and might actually be useful for a few high-boost engines where heat is a problem. Or maybe not, I don't know.

Here is the info from the '87 model-year "Service Information" booklet. If you don't have this, it is part of the Jim Morehouse CD collection of historical documents which is available for a very small price from Roger. Besides the workshop manual, it is a treasure-chest of historical information.

Thank you for this explanation,also translation is good! I think I will get a cd from Roger.

Does the enhanced "oil storm" of a squirter suggest a better baffle is needed in the fill neck? Only if you often rev it up? I didn't have a big pool of oil in my intake, but I don't think my car's PO's were rev-happy. I'm not rev-happy, either. Reciprocating loads ~ RPM^2.

I'd like to think of it blissfully as a generally harmless rarity, a distinction, a good thing in the crazy world of vintage cars.
