Piston oil jets (Oil Squirters)

Another fun shipment arrived today.

These are genuine mercedes squirters. Thanks Euro truck. I will try to document the process of machining the block to accept these. (my block does not have any machine work done to facilitate jets)

If anyone needs info off these jets, let me know before they make it to the machine shop. They do look a bit different than some I have seen, but they will do the job.

I was going to make my own jets, but I didn't now how big the jet orifice was so I was unsure of flow rating for them.

If I were to make my own, I would consider brazing a tube into a threaded plug, then machine the block with only threads and no spot face. Then bend the tube by hand to aim the jet. This would make it almost possible to install these while the engine is in the truck still.

What do the non-machined blocks have ? Just virgin casting ? Or is there a boss cast in the 'proper' place that one needs to finish machine ?

...or should I just wait for the documentation to continue ?

Well, if you look at the pic Snow posted, you see the raised area where the jets go. This is just virgin cast material. So you have to spot face that area to give yourself something to seat to. Then you have to drill the hole for the banjo bolt and the alignment pin. Then you must drill from the bolt hole you made into the main oil galley. Then you can thread for the banjo bolt. At this point you are done. Just install the jets and go.

I am going to start her with the stock n/a 352 pump. If I see oil pressure drops, I will upgrade to an hd pump. But the cost is pretty high.

nozzles and bolts were $180 shipped. Very pricey, but worth the peace of mind.

It would be nice to have pics of the mechanic proses when the squirters where machinered in to the block but i understand if it could´t be done. Because you sent it to a machinery shop.
