Oil dipstick cylinder (where the oil dipstick goes in) from the main engine block is loose. I can move it left and right, up and down by about half a centimetre. (1/4 inch)

WTF, from the looks of the cylinder it looks like a press fit assembly.

I went to the dealer today to get it checked. After inspection, they are going to order a new part to replace it.. all under warranty. I'm not too confident that it's the fix.. but I hope to proved otherwise.

Has this happened to anyone else??

 

yup. mines like that as well. I dont care as long as oils not spilling all over the place.

 

Austin has that same problem.

 

Edwin,

Time to move up to a JDM style header

Regards,

 

???

 

How many miles do you have on your car?

 

happened to me and my buddys Type-R too, my mechanic said its normal under hard driving and hot conditions. He fixed it up in about 20minutes, no new part was needed.

 

Do you remember what he did to fix it?

 

Well you see in order to fix the problem the stock exhaust manifold will have to come off the car. Since it is off the car, why put it back on!?

Besides, anytime is a good time to move up to a JDM style header

Regards,

 

i remeber vaguely, i know for a fact that the headers didnt need to be removed, except for the heat shield. He used a hammer and some kinda long screwdriver to bang the the opening of the dipstick hole clockwise so it would tighten up again. Becos all it was is that peice was loose and just needed to be tighten.

 

I would imagine the oil dipstick cylinder would be able to be removed since they are ordering a new piece to replace it??

Anyways, I'll give an update when and if the problem is fixed.

I have roughly 9,500KM on my car.

 

As long as the heat shield is covering the stock exhaust manifold I won't need a JDM heater.

I don't want to mess up my AF ratio with a JDM header unless I have a tuning system in place.

Anyways, BabyNSX it gives me satisfaction to beat your car with stock engine pieces in place. Haha.. JK

I noticed mine had the same problem when I put a header on it a few months back (I could actually pull the thing out of the block though). It had apprently been loose for a while because I had some oil oozing down the front of the block. Acura ordered the part and fixed it no problem (BTW I had about 13,000 miles on it at the time).

 

I'll keep on a look out for this.

 

What kinda crap is that?

 

If you change a part ie. exhaust manifold (header) you are inherantly going to affect the AF ratio. The ECU don't know about your new fandangle part and will run lean.

Sure the header is going to make the car faster, your leaning the mix, however without correction in the AF ratio the car is not run at the ideal mix.

Before I jump into engine power gains, I look for engine management.

As the Pirelli commericials state "Power is nothing without Control" haha..

 

Doesn't the ECU "learn" that the car has increased the airflow hence everyone recommends that you reset the ECU after a mod.

 

The ECU also has this thing called an O2 sensor. This is really neato since it allows your computer to read your a/f ratio and keep it stioch. So, no need to worry about a header messing up your a/f ratio.

 

heh, didn't even think about that

 

the oil dip stick cylinder is a press fitted piece. in the past all ive done was take a long flat head and tap on the flared out piece near the block (front,back and of course side to side) and it should slip right back into place of course if your really worried about it possibly leaking which it wont put a thin layer of j.b. weld around the bottom and no more probs ever!

 

I don't think the ECU can learn and reprogram it's own timing and fuel maps after resetting.

I think a reset will have it loose it's current engine check codes. But after startup and it checks all the sensor the codes will return.

If reseting worked then why is there a market for VAFC and ITCs --- devices that manipulates the MAF sensor and Ignition Timing.

 

Correct you are!

The 02 sensor only comes into play when the engine is running in a closed loop mode, and this only occurs when the engine is running under light load conditions. Under full throttle conditions (when it matters) the ECU relies on the stored fuel and ignition maps to control the engine. These are not learned over time and remain fixed, resetting the ECU won’t change this!

But honestly, I don't think that adding a header will change the burn enough to cause a problem. Don't forget that the stock maps are plenty rich enough. Even after the common I/H/E mods most people end up leaning out the mixture further to get the most out of the engine.

Anyway Edwin, I didn't see you pulling on me when we were chasing down that S4!

Regards,

 

Riight.. and a stock ITR has perfect A/F from the factory, right?

If anything.. it runs rich and the JDM header will HELP more than hurt.

 

Update: brought to the dealer last Saturday, they replaced the dipstick morons.. showed them the problem yesterday and replaced the oil dipstick cylinder. The cylinder is solid as a rock now.

 

Edwins' R back in full pimp mode baby!
