Rye IPA Batch #21



#20

 I found a 24oz bottle of #20 in the mash ton. It was a pleasant  surprise to be sipping on this while brewing #21.


Boiling

No chocolate or roasted malts for this batch.

Hop Additions

Added hops at 15 minute intervals.


Rye IPA #21
I have been leaving room in the carboy so I don't have to worry about a blow off tube. This batch developed a 1 inch cap but after it stirred it up on day 3, a 6 inch head developed and then settled down.

Will do a trub rinse and get back to 5 gal later.

9 lb 2-row
1/2 lb cara-pils
1 lb crystal at 50 L
2 lb rye

1 oz norther brewer @10.6%
1 oz cascade @ 3.2%
1 oz sterling @ 7.0%

safale us-05

Exploring the cara-pils malt in order to develop some extra body. When you have a low crystal malt content, your beer can taste perfect yet have a hollow mouth feel. To add some body, throw in some non fermenting malts. Will comment on this as things progress.

Hops were added strongest to weakest. Cascade was divided in 3 parts, the other two were divided in 4 parts.



Update 3/31/13 Happy Easter

Next Batch revisions

9 10 lb 2-row
1/2 lb cara-pils 1lb Oatmeat for mouth feel
1 lb crystal at 50 L 1/4lb Chocolate Wheat
2 lb rye

1 oz norther brewer  Galena
1 oz cascade Kent
1 oz Sterling

safale us-05

After sampling a bottle I am not happy with the crystal and cara pils. To much caramel for the hop load.

About The Tools & Just In Time


Here are a few comments about the tools I needed to clean the manifold and drop the oil pan on wifeys car:


The intake valves were all closed because I pulled the intake cam shaft. When I wasted several cans of carb cleaner, brake cleaner, starting fluid, and anything else I had into each inlet port, I needed a way to empty each valve cavity of the primordial black ooze that was just created.

I tried using an old turkey baster and it lasted one suction. The chemicals went into the bulb and melted a hole through the bulb sidewall. This anti-freeze checker turned out to be more reliable than the old turkey baster. The next time I am in the market for a turkey baster, I'm heading to the auto part store.

Who has never used a turkey baster for some odd job around the work shop? I could have used my shop vac but it is in the land fill after I destroyed it while using it to clean the furnace. This is a whole 'nother story.

I could have used compressed air, but this would deposit carbon black on everything, including me, so I settled for the  more conventional approach.

After each pool of black goo was suctioned out with this make shift boogie puller, then I deployed the compressed air. As I was air lancing out each inlet the counter flow of air, pointed in my direction, pelted me with grit containing grains of sand sized black paint balls. My glasses and field jacket took the brunt of the splatter.


Here is a pic of one make-shift work table. At the end of the day or after a major task was complete, I would carry the tray of tools and parts into the basement. Then I would come back outside this a new empty board. This occurred four times.


Moving on to the oil pan removal, things went along smoothly. The re-installation, however, was different. There were three bolts that were at nearly impossible to get back in the holes. I would get a bolt in but it would immediately cross thread. I always wondered why they made ball end Allen wrenches. Now I know.



Except I didn't have one. But I did have a file. The car is all metric but I needed a slightly smaller wrench so the clearances wouldn't be too much of a pain when tilting the wrench sideways in the socket. So I sacrificed my 3/16" English wrench because the next size lower in metric was too small.


The most used tools were the telescoping magnet and the grabby thing. I fished out more tools and bolts than I can count. One bolt went down the air line to the turbo. The grabby thing has magnets so I was able to retrieve the bolt w/o taking the whole turbo air line apart.


 

The car is back together but the mess in the basement is a disaster area. I know there is a grace period for  cleaning up such things. I am thinking by next week end. Wifey will overrule this, I can predict with absolute certainty. Nuclear physicists say you can only predict velocity or position of charged particles. I can predict both the speed and position of this cleaning operation.



The car rolled out of the bay with minutes to spare. An hour passed and then the global warming moved in. You can see the tire tracks if you look closely.

A heated garage would be nice. In the next house maybe. This gives me an idea. Garage with room above on my side. Kitchen with other rooms on her side. Possibly, even someplace even warmer than here.

Like a Rocket, Don't Forget The Oil Pan

So I got the whole thing put together and the moment of truth arrived. After opening the driver side door several times to charge the low pressure fuel system, I cranked it over in 5 short attempts. On the sixth or seventh try it caught and it chugged and sputtered for a moment, then the engine settled down to 750 rpm as smooth as the day we drove the car home.

I went for a test drive around the block. Our block is 4 mi North, 8 mile South and back 4 miles north. The mileage counter while cruising down hill was indicating mid 40's mpg. After I returned home I decided to go get an oil filter and a couple of stogies. On the 30 mile round trip the mileage counter was indicating 37 mpg. This is up from 29 mpg before the valve cleaning.

In the back of my mind I am thinking am I done yet? I still had all those unaccounted for parts in the oil pan. So I dropped the pan. And, it is getting very late.

'07 2.0T FSI Oil Pan
The pan came off easily enough, except for those bolts located next to the transmission. The wrench had a ~15 deg angle in order to engage the socket. How the heck am I getting these back on?

Bits And Pieces
 Here is some of the junk that I found. The large pieces aren't the problem. It's the small ones that can make it through the oil strainer that I am worried about. There appears to be pieces of ceramic in there. I am wondering if it is from the oil because this stuff doesn't look like engine material. From now on I am filtering my oil through a nylon stocking, to see what I might find.

Oil Pump Suction Strainer
I worked on this for 15 minutes and got a pile of junk out of it. I flushed it with WD-40 and light weight tool oil several times.

I lost a pan bolt so I will resume the search for the bolt in daylight. And the beer that was supposed to be bottled yesterday, it can wait.

What's Wrong With The 2.0T FSI Engine

 The 2.0T FSI engine is a heck of a power plant when the engine is new. However, after some age, you question whether the direct fuel injected engine is a good idea.

Because the gas from the injectors does not flow over the intake valves, the valves and chambers are subject to fouling. If I were to design a direct injected engine, I would have a method to clean the intake valves on a regular basis. I envision a schrader valves on the manifold in front of each intake. This way, you can dump a can of carburetor cleaner in each cylinder at 15k to 20k miles intervals to clean the valves.


I  think we have a good understanding why the car was having trouble starting in the morning and why the check engine light was always on. The oxygen sensors must have been going crazy.

This is what the valves look like after 134k miles.

 Intake Valves Before

 After I managed to peel the manifold off, I wasted a can of brake cleaner in the inlet chambers. Brake cleaner was all  I had on hand. Then I wiped around using my finger and a rag. I had rubber gloves on and the brake cleaner melted the gloves. So the picture above is improved from what it was prior to my first cleaning effort. Each valve was at least 50% blocked.


Cleansers And Cleaners

This is how I left them. Day light was burning and I had to get the cam shaft reinstalled.


Intake Valves After

I hope to have the car all put back together by tomorrow evening before the global warming arrives.

Be Sure To Change Your Cam Follower at 100K Miles

High Pressure Fuel Pump Lobes Are Scored

No 1 Cylinder At TDC
So your 2.0T engine gets 30+ miles per gallon. It is because of all that fancy crap that goes wrong as the engine gets up there in miles.

The high pressure fuel pump is driven from the front intake cam. The cam follower is a thimble like cup that spreads the load of the pump plunger rod across the entire surface of the cam lobe. When the cam follower  fails, the reciprocating pump shaft which is about the diameter of a pencil rides directly on the cam. Synthetic oil is good but the film of oil can't stand up to the forces as the metal plunger rod is honed down to cutting tool-like edge.


High Pressure Pump
After I install the new cam and pump, I need to drop the oil pan and try to find all of the parts that I expected to find in the housing that bolts on to that the right side of the engine.

The next time I am going for the 5 cylinder engine without the turbo and fsi. I am willing to sacrifice 5 mpg in order to skip this kind of trouble. This issue is costing me the equivalent of 17,000 miles, which is the same amount of money for one of those nice smart 50 in flat screens.

I can't image dealing with hybrid batteries.

I Rinsed, I Tasted, I'm Shocked.

Free Beer

After the beer is siphoned to the secondary it always seems as though a gallon has disappeared. But it is really hidden in the trub. So I recover that gallon by adding another gallon of tap water.

My theory is that all the beer that is mixed in among the hops isn't going to come out due to some sort of surface tension. By adding oxygenated water the yeast is revitalized and the thinner solution slips away form the hops with ease.

This pic is after ~12 hr of adding water. The mess at the bottom is more compact and the beer on top is getting darker by the hour.

Will mix it up another time and then siphon off the good stuff tomorrow.

When I transferred to the secondary I sampled the five day old beer. My first reaction was "Holy Crap!" Wifey said "Whats wrong?" I replied "I just discovered SN's Ruthless Rye formula" because at 5 days, it tastes exactly like it. I was tempted to take another larger sample, but reason prevailed. Double blind taste tests will happen.
