Hello Guys,

 

I am going to replace the spark plug in my 2002 Octavia 1.8T AGU Factory  Stock with no engine mods.

 

Skoda dealers says I need 101-000-063AA Platinum Plugs. Do this plugs come already with the correct Gap?

 

I was checking NGK PFR 6Q since they cost less. Do this plugs come also with the correct gap?

 

I am pretty sure I can install the plugs myself but I dont know how to gap a plug neither have the tool.

 

Do I need to put anti-seize lubricant to the treaded part of the spark plug?

 

THX,

 

Isaac

No need for anti seize and they will be gapped fine out of the box

Yeah I agree. I've done mine lately and although I checked the gap they didn't need altered new. I've always used NGK plugs in mine never been a problem.

I never trust any plug gap straight from the box TBH,

 

So I always check for best running.

 

If the gap is around .32" or 0.8mm then spot on.

 

no need to for thread lube.

Agreed, I always check the gap before fitting too.

Some of the vag ones are like a 3 prong with centre bit so can't be adjusted?

the genuine vag spark plugs are ngk sourced anyway, they sometimes also have an ngk stamp on them next to the vw/audi one, there is more than one type of plug listed for the agu engine though so be careful that you choose the correct type

Hey Guys,

 

I was thinking to replace the spark plugs because my engine is consuming a lot of gasoline. I always reset the trip odometer when I full the gas tank and I was notice a big decrease.

 

So today I call the Skoda dealer and ask the spare parts guy if he has in stock the spark plugs for my car. I tell him I have read in the net that my car need 101-000-063AA. He ask me for my chassis number, I gave him the long number TMBAL41U928549849 and my car is a 2002 Octavia 1.8T AGU.

 

He toll me that the correct Spark Plugs for my car are: 101-000-051AA. So I went to my car, and took out the spark plug that is close to the timing belt area and to my surprise the spark plug was a 101-000-051AA made by Bosh part No. F7LTCR and the Skoda dealer are the ones that do my maintenance, so they put does plugs at the 40,000kms maintenance

 

Things I notice on the removed spark plug:

 

1) The spark plug was cover with engine oil, inclusive the treaded part was also cover with engine oil. I cleaned with a towel and its look like the color/combustion is OK. Electrode looks like new. I am pretty sure this plugs has like 20,000 kms. (Car has right now 60,000kms.) Please check the my plug pic.

 

My last engine oil change was 5,000 kms ago and I check it today, and I need to top it with 1/2 quart. Usually I have never has to add oil between changes. Always use Castrol Synthetic 0W-30 the one thats is made in Germany and change it every 7,500kms

 

So do the oil on the plug is a normal thing? Do I need to worry about? Any advise? Do I need to change to 0W-40 or 5W-40 oil?

 

Is there is a better spark plug or can I keep using the same VAG part number?

 

2) I also found a cracked brake booster pipe were it attach to a check valve. Car was breaking OK and I never notice the brake pedal was harder to press but I am pretty sure that it was loosing vacum in that part. I started the engine and can hear the sssssssss air noise. Skoda dealer have the part in back order for me so I fix it with electrical tape and some plastic zip tie.

 

Can this vacum loss can make my engine consuming more gasoline?

 

I dont have Vag Com to check for any codes.

 

Thx,

The reason you have oil on your spark plugs is because your cam cover internal gasket is leaking. The cam cover has 2 gaskets , the large outer one that runs around the main cam cover and the inner one that has 4 rings in it that sit around the spark plug holes . When the inner one goes hard it starts to leak oil down the plug holes that sits on top of plugs. This is also your reason for loosing some oil.

Wow. Lots of questions there! You don't actually say what mpg your getting so its difficult to answer. Mine isn't great round town maybe mid to late twenties. Your plugs look a good colour. If oil was on the electrelode part I don't think that's great news but I don't know if your saying it was. If it was just the threads and top part check if the well around the plug has oil in it. My rocker cover gasket was leaking into there so that could explain the oil usage, although I'm not entirely sure your using the right oil. I thought 5w30 long life or 10w40 was for the 1.8t engines. I'm still not sure about Bosch plugs either I would go with NGK.

Ah beat me!

Ah beat me!

Lol..quicker off the draw dude...

Hey Bowder1, I think you're absolutely right in relation to the internal valve gasket leaking. The truth is that gasket thing never crossed my mind.  Thank you.

 

I will order a new gasket set and I am thinking to also use some high temp RTV silicone gasket and applied all the way with the valve outer/inner gasket

 

Any advise?

Hey Meaty101, I know that driving in the city I make like 350 kms with a full tank, I am getting like 250kms with a full tank, so something is wrong.  I will check this next full tank is the temporary fix I made to the brake booster pipe help in my fuel consumption.

 

The oil was on the treaded part of the plug. Thats why I was like :think:

 

Regarding the BOSH brand, this plug is a factory VAG part number 101-000-051AA. This number was in the plug. Also on the white ceramic part of the plug was stamped BOSH and on the other side was stamped the Audi logo and there was also the Bosh reference F7LTCR. So its look like not only NGK made VAG plugs

 

I begin to use Castrol Synthetic 0W-30 on my 2nd or 3er oil change when  I got the car from new because I was experiencing every day on the first start hydraulic lifters noises and this oil cure the problem. This oil is VAG approved and is used in Europe as long life. Maybe ion Europe they called with another name but the way I  recognize it is because in the bag of the bottle it say Made in Germany.

 

Cheers,

No don't use any high temp sealant. Just use the gasket as they are. They are designed for the purpose. You do not want gasket sealant going down oil ways and blocking engine internals.

No need for sealant all the way round buddy. Sealant is only needed at four points. Where the gasket meets the cam bearings on either side just put a dab back and front of each bearing. Like I've said mine was leaking into the spark plug wells but when I had the car up on axle stands the back of the engine was drenched in oil but I couldn't see anything from under the bonnet. That's why it seems like they're using a lot of oil.

OK, I will not use sealant.

 

Was checking my file were I put all my car expenses and notice that on the year 2011 at 52,000 kms the Skoda dealer replaced my valve gasket part No. 058-198-025A. Now my car has 60,000kms and I have this valve gasket problem!

 

Dont know what to think about it

 

Any one has a clue?

Beat me again!!

You need to make sure it's leaking. Wipe inside the plug wells as best you can making sure all the oil is dried up. Run the car for a week or so then check again. If its oily again take the car back to the garage who fitted your gasket along with the receipt for the work and complain. A new gasket should last longer than 8k.

Beat me again!!

I am watching you buddy...

They probably only changed the outer cam cover gasket buddy and not the inner one. The fact is you have oil on the tops of your plugs. That comes from only one place.

Stop thinking about it and just replace it

No need for anti-seize? Unless you're threading steel into something bronze or brass based, anything that varies in temperature greatly will ALWAYS benefit from anti-seize.

 

And threading dry steel into aluminium is an absolute no-no.

Sealant on the gasket is required on the corners,it is in the Skoda repair manual

 

 

I didn't do that with mine. I just put a little on the cam shaft bearings where it meets the gasket. No leaks its been fine. Whichever way its done, no need for sealant all the way round the gasket.

Yep that is what I did as the gasket hoops upwards in a curve there so best to get it sealed with a 5mm bead.
