[B]here we go again... no flow and you get 100% pressure drop, ie, nothing coming out of the nozzle.

...... my example is to plug the nozzle and notice the effect at the banjo bolt.

 

Take you time... I'm not holding my breath

 

.... one question .... Do you actually work as an Engineer?
seems like we haven't been able to communicate well over the years......
I'm still puzzled by this thread:

just to mention a few....

 

Do I work as an engineer? Do I work as an engineer? God, no. I didn't even go to school, you see. It's just that a common passion for camembert, guinness and watches brought me in contact with Claude N., George S. and Claude B. who were kind enough to teach me a thing or two. Everytime I need I give them a (really) long distance call. Though Claude B. is pretty useless. His french is a bit rusty and he doesn't deal in oils.

Right. The clicking torque wrench. Unfinished business. As for the rotors, I was right. The slight difference in temps didn't make a yota of a difference. I have 30,000 kms on them to prove it.

Now... shall we move onto the wider tyre / larger patch topic? ... Or can we get back on topic?

 

Why are we second guessing Honda? Can't someone there tell us the reason for the different bolts. We (collectively you) may be way off here.

 

We have Honda words below.. this thread is just speculation on technical details.

2. Symptom
Under certain conditions, the lubrication and cooling of the pistons may be insufficient. If the engine is continued to be used in severe high load conditions this may result in premature wear of components and an increase in the engine operating noise level.

3. Cause
The flow characteristics of the oil jets may be insufficient under certain engine operating conditions.

4. Countermeasure
The flow characteristic of the oil jets has been changed to improve piston cooling and lubrication.

 

I've been off the board for some time because I just started law school and that doesn't leave me much free time. Also, I didn't have my car with me for the last two months while I was sorting out my parking situation at my new apartment.

Anyway...

When I last was on the board regularly, I had heard about the new bolts for Europe and expected much news to come. Apparently, all that has happened is everyone is fighting (as usual) over the physics behind everything and no one can agree on what color the sky is.

1. Is there any way to get these bolts here in America?
2. Someone mentioned the install is tough... How tough? Do I just need to drop the oil pan and maneuver around a little to replace them? Or do I need to basically disassemble the bottom end of the engine???

My take on this is Honda wouldn't spend all this money doing a European recall or service bulletin (whatever it was) if there wasn't a problem and this wasn't going to help.

FWIW, I would guess the reason for the change is that a 2-hole banjo bolt tightened such that the holes are each 90 degrees from the oulet of the fitting you are connecting to will probably not flow as much oil as a 2-hole banjo bolt tightened with one hole completely lined up with the outlet and one hole 180 off. By switching to 4 holes, they are probably just trying to minimize the variance that comes when you tighten the bolt and can't see where the holes face. I don't think it's necessarily that they needed more or less overall volume, just that they needed more consistency between all four cylinders when you can't necessarily control where the holes will point. That's my guess anyway.

 

So in light on Honda's actions, those certain conditions exist in Europe but not to as significant a degree in North America, if at all...

We have all been through this discussion before, havn't we? Sorry for reiterating...
