I wasn't necessarily endorsing the removable squirter for everyday use. Just pointing out the use of the retaining compound to hold their version in place. I recognize that an always-open squirter isn't for everyone. Since the engine in this case is a "race" engine, it's expected use was primarily high rpm operation. That said, it's understood that the engine is streetable and can idle w/out suffering oil pressure problems. Another thing to consider is that often times there are some squirters are found to be stuck open when doing a rebuild. Often times guys can free them up by treating them with solvent like Seafoam or similar.

I don't think anyone's worrying about the use of the retaining compound for the squirter placement. It's right there in the technical documentation. And thanks for scaring everyone about riding in their plane on the way to Disneyworld.........

Looking forward to the announcement and description of your version of the squirters. I will hold off installing the ones I have for now. I've got lots of other rebuild-related things I can be doing, like cleaning various pieces and parts etc... should keep me busy for quite a while at the pace I run...
Thanks,
Tom

Thanks Tom, will be any day now.....

LOL.....

Yeah it has it in the tech documentation but Porsche advocated staking the stock squirters because they didn't trust the adhesive.

If you use 640 per the manufacturer's instructions, staking is totally not required - that was my point.

Catroce, I am going to be replacing the squirters in my 993 engine here soon after the final time it is machined for quad rings. I wanted to use the 993 turbo or RS squirters. I have the part number for the 993 turbo squirters that is 993.101.018.51. Looks like these have been superseded to 993.101.018.53 now. Can you confirm that?

How will your squirters flow vs the stock 993/turbo squirters? Any idea on what the cost per unit will be?

Tocobill,

The flow rates of mine are similar or the same even though the internal geometry is different. The reason I say "similar" rather than "identical" is that there are a lot of factors that determine the flow of the squirters, chief of which is oil pressure and the type of oil pump used. But generally, mine will be similar.

The largest orifice you can get from Porsche is 2.0mm (964/993 sized). I make one in 2.5mm but it has the same flow as the Porsche 2.0 because my internal geometry is different.

I'll have a video posted later this week then people can make their own determination.

As to the stock ones, I too am showing it superseded to the part number you specified.

My squirters cost $45 each, that part I can tell you definitively. Stay tuned for more!

Hi Catorce,
Just curious where you are w/additional info & the availability of your squirters. I'm part way through removing my originals (at least the questionable ones) and am not sure about using the ones my machine shop provided as replacements. They are not stock OEM Porsche squirters, but ones of their own making, which for all I know are just as good or better than OEM... but I'm just not sure how to proceed - trying to give myself and this engine the greatest chance for success.
Thanks,
Tom

OK, been making a little headway on removing the old squirters ("little" being the operative word...). I've been following the procedure outlined in this thread: Anybody here ever replaced piston squirters? by fastfredracing.

A quick summary:
1. drill out top of existing squirter w/5/32" drill
2. remove spring & ball
3. drill through bottom of squirter w/5/32" drill
4. tap squirter w/5mm tap
5. carefully dremmel staked case marks at top of squirter to ease extraction
5. fabricate slide hammer w/5mm bolt end attachment, which gets screwed into tapped existing squirter
6. gently heat case area around squirter
7. use slide hammer to extract existing squirter remains
8. be happy

I'm stuck at #7. Or rather the squirters are stuck in the case & won't budge with semi-gentle tapping w/the slide hammer. I'm afraid I will strip the threads out of the squirter as they are really soft aluminum and the 5mm tap is barely big enough to cut threads into it except at the bottom...

Anyone have suggestions for another extraction method? More heat? Bigger tap & bolt?

Thanks,
Tom

Tom,

What I like to do is take your 5mm tap and chuck it right into the drill. Drive it in the old squirter, try and get a grip on it then yank it out. Usually they will spin right out, remaining attached to the tap. Don't sweat it, use force, they come out easily. YOU WILL NOT DAMAGE THE CASE. Even if you shave a hair off the case by accident you can go to the oversize squirters. No big deal. Spin the tap vigorously into the squirter. IT WILL COME LOOSE, no heat required.

I'm waiting on the patent filings to post further, my squrters are done, videos are done, etc. I know I fhave been saying this a while but I am waiting on an attorney, what can I say, LOL......

any day now.

Thanks for the tips, I appreciate it. I'm not so concerned w/hurting the case, but AM concerned about using enough force to strip the minimal threads the tap put into the squirter and being left with nothing to grab onto & yank on... Maybe an easy-out would work if that happens? or maybe I will do some math and figure if there is an SAE sized tap that's bigger than 5mm, but smaller than the 6mm-ish that is the ID of the squirter hole...

No worries on your timeline w/the lawyer stuff etc... I'm moving at glacial pace...

Thanks,
Tom

PS: here's another pretty slick method I found on youtube...

You don't have to sweat ruining the squirter at all and worrying that it won't be left in there, because a 6mm drill bit will remove it completely if need be. The OD of the squirter is 6mm on the nose. If you oval the hole, you can use a 6.4mm diameter bit and use the oversize squirters.

That method shown in the video is not unlike removing the camshaft housing spray tube plugs on the ends of the housing. Drill a hole with a suitable drill bit for your chosen tap size, tap it accordingly, then use a screw and spacer assembly (a small socket with a decent size washer) to easily pull the plug out.
