(PICTURES UPDATED) A quick D.I.Y. Cam Chain and Tensioner *BPY engines
A quick D.I.Y. Cam Chain and Tensioner *BPY engines
This in not the most in depth write up ever but it will help many of you out to see what you are getting into (It's not that hard) just looks it.
I do want to start by saying I am not responsible in anyway for your actions and anything that may happen as a result of you doing this on your own.
The tools you will need are the following:
T40080 - 6 point socket
T10252 - Cam Lock
T10020 - 2 pin cam wrench (optional)
Ratchets - 1/4", 3/8", and 1/2"
1/2" Breaker Bar
Extensions for all three. 3" for the 1/4" and 6" extractions for the 3/8" and 1/2"
T27 Socket and Screw Driver Bit
10mm Socket
5/8 Spark Plug Socket (optional)
15mm Wrench
M8 Triple square (If you have the banjo style fuel pump)
Pick sets
Screw Drivers, both Standard and Philips head
Safety Glasses would be a good idea too.
Might need a few other little things but this is most of them
Parts you will need: - cost for parts was about $178 plus $100 for the tool kit I bought. The gaskets where all VW brand. The chain was IWIS (same as factory) as pictured and the Tensioner was from INA (same as factory) as pictured. The prices are cheaper from the companies separate compared to buying them straight from VW.
Timing cover gasket - $9
Valve cover gasket - $17
Exhaust cam adjuster bolt - $4
Timing chain - $31
timing chain tensioner - $59
HPFP cam follower (optional) - crazy if you don't while you already have it apart. - $50 with new bolts and gasket
Hose clamp - to replace factory clamp on the rear pcv hose from valve cover $1
Timing tools if you don't already have them - $100
Step One - Make sure the car is in Neutral so the engine can rotate freely. Remove your intake system (whatever brand you may have) This should be pretty simple. Not going to explain because so many mount differently. Make sure to cover the turbo inlet so you don't drop anything down in it. Paint can lid works pretty well.
Step Two - Remove the battery and battery tray. (Optional) I did this this to make more room to work and I am glad I did, You will want the room to gain access and see the lower bolts on the cam cover and to wiggle the cover off.
Step Three - Now it is time to start disconnecting all the plugs on the top end such as fuel pump connectors, Coil Packs, and N205 Valve. You will want to pull the coil packs out at this time. Also disconnect the vacuum line off the cam cover. If you have an aftermarket heat shield, this will also be a good time to take it out. You will want to disconnect the rear two hoses on the valve cover and all the hoses off the front PCV system.
Step Four - Time to remove the fuel pump and follower. Now is also a good time to replace it since you already have to remove the old one. This is pretty simple but make sure you have rags on hand as fuel will come out when you drain the system. You will want to unscrew the cap on the bottom right of the pump and push in the tap to release the fuel pressure. This will drain fuel out so have a rag under it. After it is drained, remove the fitting from the pump to gain access to the bolt behind it. You will want to also remove the two fuel lines under the pump as well, I have the 15mm line and the Banjo bolt which is not as bad as everyone says. Put the tripple square in a socket with a 3" extension on a 1/4 drive ratchet and it comes out in less then two minute. Below is a pic showing how to do it. After they are disconnected, You can now take off the 3 bolts holding the fuel pump on and remove it.
Step Five - Now it is time to remove the Valve cover and Cam Chain cover. You will need lots of rags and the cam cover will leak on the top of the trans. All the bolts here will be T27s. The valve cover is real simple. It's 14 bolts up top and 2 on the left side where the timing belt is. The just wiggle it side to side and it should come right off. You might need to pry at it, If you do, Just be very careful not to crack or break anything. The chain cover it a little bit of a pain to get the lower bolts and this is where you will be glad you removed the battery. There are 3 up top, 2 around the back, 1 under the fuel pump are, and 1 last little sucker under in the center, You will not be able to get it with a T27 socket, You have to have the bit and screwdriver for this guy. He was tucked up in so I couldn't get a good picture. You will also need to remove the 2 bolts shown in the second pic as well as removing the wire loom holder. The third pic is to show the bottom bolt location and how it is surrounded by the case. After all the bolts are removed from the housing you can now take it off, To do this, IT MUST COME STRAIGHT OUT THE SIDE, you might have to bend some of the medal lines slightly to do so but you don't want to break the rings in the housing by bending it around. Just be gentle and careful when doing this and you will be fine.
Step Six - At this point, the tricky stuff is done. The rest is easy. Now we need to rotate the engine to get the cams lined up to lock them in place. It is (optional) if you want to remove the spark plugs to make this a little easier, I did to release the compression as I rotated the engine. Here is where the 2 pin cam wrench come in, You will want to slip it in the intake cam and rotate the engine around the the notch on each cam face each other, once they do, slide the locking plate in and bolt it in to 7 ft lbs. You can now press the tensioner down and insert the locking pin to hold it down.
Step Seven - Time to remove the camshaft adjuster bolt and take the chain off. To do this, You need a the T40080 socket and a breaker bar. I had my brother hold the socket square and in while I pulled to break it loose. Don't be afraid to give it some force, they are designed to hold in there tight. Once it is out, You can then just slide the adjuster and chain right off.
Step Eight - We can now remove the old tensioner, It is held on by 3 T27 bolts and comes right out. After it is out, Clean up the oil passage hole, mine had some build up in the screen on the tensioner. It would explain why it was ticking.
The rest is just a matter of reverse bolting everything back up the way it came out.
Torque specs are the following All are ft lbs.
Cam adjuster bolt is 15 lbs plus additional 1/8 turn
Tensioner bolt is 7 lbs
Valve cover bolts are 7 lbs.
Cam chain case cover is 7 lbs
hpfp bolts are 7lbs
banjo bolt on fuel pump is 13 lbs
union nut on hpfp is 18 lbs
On a scale of 1-10 on how hard, I would rate a 6. It's not hard so much as how long it takes. You really do need the special tools to get the job done though. If not, You are going to break something.
Here is the Valve cover pattern to tighten down to 7ft Lbs.
If you need any help, feel I left anything out, or any question, feel free to message me and I will see what I can do to help, add, fix, or change.
