B18C Upper & Lower VTEC Solenoid Rebuild & Gaskets

Been having some oil leaks. From what seams to be around the solenoid. So I did a little research and this is a common problem.
Order some gaskets from ebay and in they went.
Apparently all the solenoids use the same gasket.
Took half an hour to swap.
I didn't have any torque settings. But being a gasket I always slowly do up the bolts in three stages.





I rubbed some oil on the gasket to help it compress.
I pulled the solenoid and shaft apart and gave it a clean with degreaser.
Three bolts to remove it from the block and a couple cables to take off.
Oil pressure switch i believe is one, the other is the solenoid control and the other is a clip holding the bracket for the ignition leads.

Goddam she was dirty, no wonder there were issues.


According to the OEM Packets:

15825-P08-005
36172-P08-015




Gave the surface a clean, remove any debris











I believe this metal spacer is for an oil feed?
Remove it to get to the shaft n spring.

And after the civic service. On  to the Z27AG for some rewiring.

Research into Colder Spark Plugs - Z27AG & CT9A & WRX STi - 14mm dia × 26.5mm LongReach - 16mm

I previously posted some info here http://ayu452.blogspot.com.au/2011/09/z27ag-spark-plugs-ilzfr6c-k-ikh22.html about plugs.
But I have recently found out a good rule of thumb is to run a colder plug ever 100hp increase.
At the moment i am guessing i run about 260HP and want to go one step colder.
From my research the stock plug is a #6
I want to go a #7 so this should include the HKS M35iL or a NGK MAX Iridium Spark Plugs LFR7AIX-P or Denso Iridium Power IKH22 (is one heat range colder than IKH20 whichi  believe is a 6).

Gapping - http://www.ngksparkplugs.com/
Another consideration that should be taken into account is the extent of any modifications that you may have made to the engine. As an example, when you raise compression or add forced induction (a turbo system, nitrous or supercharger kit) you must reduce the gap (about .004" for every 50 hp you add). However, when you add a high power ignition system (such as those offered by MSD, Crane, Nology) you can open the gap from .002-.005".

Colder Plugs
Denso description -

When the air temperature is high (summer):
The inlet air temperature also becomes higher, increasing the load to the engine. Choose a plug with a higher heat range.
If horsepower has been increased through tuning:
The increase in explosive power leads to an increase in combustion chamber temperature, making pre-ignition more likely. Choose a plug with a higher heat range and a higher level of heat resistance.

Z27AG Workshop Work

Audi A3 Brake and Rotor Service

hardest brake job to date for me. Fronts were normal, rattle gun took them off easy enough.
The annoying bit was trying to get the piston back and then push the pad into place. It has some weird tension clip around the floating caliper.
The passenger side had a temp sensor or wear sensor. No idea. Audi over engineered the car with an abundance for useless sensors.









Rears were really annoying. 12 sided star to remove the caliper. Really difficult position to get leverage.
Use a 13mm and 15mm to remove the floating caliper.
11mm to remove the brake nipple. One caliper retracted easy. The other however did not @@ Cracked the bleed nipple open but it still didn't budge.


Pad Clip >>> I bent it back so it was easier to press into the front pot

I used an air ratchet. I had to keep turning it clockwise n anti clock wise to get it to retract.
I fully extended it out to try and reseat.
I had a universal tool to screw back the pot. Funny enough it didn't fit an Audi. Out came a grinder to modify it.








Why is life so hard.
Rear rotor was siezed. No surprise there. CRC and a rubber mallet to bash it off.
The master over flowed. It must have been topped up while the pads were running low
I can usually do my colt brakes in a couple hours. This took double that. Should be quicker next time though.

27mm hub bolt.
security screw needed to remove the rotor.

Pulled apart a blown 4G15 to scope out the internals. It had lost cylinder #1. Who knows where it went @_@ Head seems fine.

I bought a wrecked colt, but to my surprise under the timing covers and behind the engine mount.







The block was cracked. The engine mount had cracked the block @_@
Head seems fine as well as all the other bits and gearbox.

It is hold in with 1 bolt (firewall side), push pins and some screws that bush in.
Took a bit of elbow grease to pull it out, as the plugs were stuck in there good with sand.
Apart from that it went it easy enough.

This is how the car sits without any guard work.

I already have a slight camber on the fronts.
These rims will most likely be used for track (that is what i tell myself). I have fallen in love with the look though.
Hope to make em fit nicely!

Previous rims were 17x7 +42 or +45 ( I can't really remember). They ran a 205/40
As seen on the photos are 205/50 on the 15x8

I was looking into the YR Advance car. They seem to run a 17x8 +35 with a 215/40. Apparently to get them to fit on the front they need around 1.5-2degree camber. The Rears have about 3mm clearance.

YR Advance 17x8 +35 Rays Rims RE30 According to my translations. They use to run a 17x7.5 +38.

I gave it a clean with some steel wool. It would come up pretty good if you hit it with metal polish. I didn't have any around.
