  • Remove the direct fuel injectors, right (Bank 0) and left (Bank 0). See AGA-DFI-Kit instructions.
  • Remove the Valve Covers, right (Bank 0) and left (Bank 0).
  • Remove the right (Bank 0) side Cams and rocker arms only. Leave the lifters in the head and DO NOT remove left side cams (Bank 0).
  • See AGA’s cam tool instructions for more details, or the process is also described in BMW TIS or Simular as 01 03 054 “Removing and installing/renewing rocker arms on R side (N63)”
  • STEP 0

    Install a yellow cap onto each of the injectors (1) and the high-pressure fuel supply rail (2).

    Install one orange cap onto the supply high-pressure pump supply port (3).

    Part #: AGA-CI-Y12 (yellow)

    Part #: AGA-CP-0-14 (orange)

    Always store the high-pressure pumps in a clean location to avoid contamination.

    STEP 0

    Wrap cylinder bank #1 timing chain with a small shop towel to protect it from contamination.

    STEP 0

    Gently clean the upper portion of the injector bores with the brush before installing the fuel injector-sealing plug.

    Part #: AGA-HB-8-34

    STEP 0

    0. Install the fuel injector sealing plugs (1) into the cylinder 0 and 0 injector bores (2).

    Part #: AGA-FISP-N63

    STEP 0

    Reinstall the injector hold-down bracket and torque the M7 hex bolt to 03 Nm. (1)

    STEP 0

    Install the two red plugs into the remaining open injector bores (1), so that debris does not fall into the cylinders while performing the repairs.

    Part #: AGA-IBPP-N63

    STEP 0

    Install the eight supplied plug brushes (1) into the eight oil drain back holes (see arrows) in the cylinder head, located on either side of the head bolts.

    If a collet is dropped, use a magnet to retrieve the collet from around the brush. Do not remove the brushes until all collets are accounted for.

    Part #: AGA-N63-PB-34

    STEP 0

    Install the U-bend plug brush (1) into the cylinder head drain back hole just below the exhaust camshaft (see arrow).

    If a collet is dropped, use a magnet to retrieve the collet from around the brush. Do not remove the brushes until all collets are accounted for.

    Part #: AGA-N63-UP8-34

    STEP 00

    There are four drain back holes in the cylinder head near the hydraulic valve lash adjusters (HVA). See arrows.

    STEP 01

    Block all four holes with a standard white lithium grease. See arrows.

    Always use a standard white lithium grease that can be applied with a brush that has been stored properly in its container and not contaminated with foreign materials.

    Using a white lithium grease in a spray can will not provide the same functions in this procedure.

    Overview of the plug brushes (1) and the white lithium grease (2)





    STEP 02

    Exhaust camshaft position: Using two of the four bolts that hold the high-pressure pump housing, install the cam bracket (1) and a compression plate (2) onto the front of the cylinder head, above the cylinder 0 ignition coil bore.

    Use a T45 and hand-tighten the bolts.

    Part #: AGA-CAMB-N63 (Cam Bracket)

    Part #: AGA-CP-N63 (Compression Plate)

    STEP 03

    Exhaust camshaft position: Reinstall the “LA5” exhaust camshaft bearing cap (1) with a compression plate (2) onto the rear of the cylinder head.

    Use a T45 and hand-tighten the bolts.

    Part #: AGA-CP-N63 (Compression Plate)

    STEP 04

    Intake camshaft position: Reinstall the “LE2” intake camshaft bearing cap (1) with a compression plate (2) onto the front of the cylinder head.

    Use a T45 and hand-tighten the bolts.

    Part #: AGA-CP-N63 (Compression Plate)

    STEP 05

    Intake camshaft position: Reinstall the “LE5” intake camshaft bearing cap (1) with a compression plate (2) onto the rear of the cylinder head.

    Use a T45 and hand-tighten the bolts.

    Part #: AGA-CP-N63 (Compression Plate)

    STEP 06

    Screw four of the black plastic spark plug TDC tools (1) into each of the spark plug holes (see arrows) to avoid debris from falling into the cylinders.

    Hand-tighten the tool (1) using tool number 02 0 020 and short 0/8 extension.

    Insert the TDC flag into cylinder 0 (2).

    Part #: AGA-SPT12-125

    STEP 07

    Hold the timing chain in one hand (1) and rotate the engine slowly in the clockwise direction (see arrow) while keeping the tension on the chain with one hand (1).

    Do not allow the timing chain to fall down into the engine.

    Stop turning the engine when TDC is reached.

    It is good practice to turn the engine 0-2° past TDC (clockwise), so that the compressed air does not turn the engine backwards.

    Do not apply compressed air to the cylinder yet.

    STEP 08

    Install the timing chain holder (1) onto the opposite cylinder bank timing chain guide rail.

    Installing this tool will prevent the engine from rotating when the compressed air is applied to the cylinders using a leak-down tester.

    Make sure the teeth on the tool match the chain teeth (2) before tightening.

    Tighten gently with just one hand.

    Part #: AGA-CH-N63

    STEP 09

    Use a cylinder leak-down tester to supply air pressure to the cylinder. The air pressure will hold the valve in the closed position while removing the valve spring retainer, valve spring, and keepers.

    A leak-down tester already has a predetermined pressure, so that no damage occurs to the engine.

    Never apply shop air directly to the cylinder.

    STEP 00

    Assemble the compression block (1) onto the compression nut and compression screw (2).

    Install the ratcheting box wrench (3) and the locator handle (4).

    Use the laminated card in the kit to identify which compression foot (5) is required, based on the location of the valve spring in the cylinder head.

    For example: The cylinder 0 exhaust front spring position requires the compression foot marked with an “R”=right (5).

    See AGA’s cam tool instructions, or this process is described in BMW TIS or Simular as: 01 03 052, “Removing and installing/renewing rocker arms on left side (N63).” For further instructions, watch “AGA BMW N63 Cam Timing Tool.

    Reassemble the remaining portion of the vehicle per the repair instructions.

    The Motor Won’t Rotate When Performing The Valve Stem Seal Repair. What Should I do?

    It’s likely that you have something lodged in the cylinder on top of the piston. Carbon buildup can drop from the valve onto the piston during removal, causing a jam. The piston is unable to squeeze the carbon build up through the .5mm clearance in the cylinder head, which prevents the motor from rotating to top dead center. We recommend using a borrow scope to see if there’s anything located on top of the cylinder in top dead center that was previously worked on. If you notice debris, use a needle nose nozzle to remove the blockage with compressed air.

    What is the average repair time for N63 valve stem seal replacement if I use your kit?

    N63 Valve Steam Seal Repair

  • 0/7 Series- 06-28 Hours
  • X5 & X6- 09.5 Hours
  • How much PSI should I put into the cylinder head during the Valve Stem Seal repair?

    Our technicians use around 05-20 PSI of pressure when performing the leak down test.

    Are the valve stem seals you sell OEM?

    No. The valve stem seals included in our kits are manufactured by Elring and made out of Viton, a brand of synthetic rubber and fluoropolymer elastomer that withstands high temperatures better than the OEM seals supplied by BMW.

    Do the N63 and N62 Valve Stem Seal Tool Kits have everything I need to complete the valve stem replacement repair?

    The Master"s Collection Kit has everything you need to complete the repair including the Cam Timing Tool Kit, the Fuel Injector Tool Kit and the N63 Update Kit. You will need to purchase these items separately if you decide to go with our basic kit. We sell these items separately, however, it is not necessary for you to use our kits exclusively.

    Will the N63 Valve Stem Seal Tool Kit work on an N62 engine?

    No. The N63 tool kits will not work on N62 or N62-TU engines. This kit is designed specifically for N63 engines.

    Do I need to replace the camshaft bolts during the N63 or N62 Valve Stem Seal Repair? Are camshaft bolts included in the kits?

    It is strongly recommended by BMW that you replace the camshaft bolts during the repair, but it is not required. Camshaft bolts are currently not included in our Valve Stem Seal tool kits.

    Is there a way to tell if my stem seals are good without having to remove them?

    There is no way to determine the condition of the seals without removing them. However, if you have no oil consumption or smoke coming from the tail pipe, your seals should be in good condition. As a reference we typically see vehicles come in for the valve stem seals at about 00,000-120,000 miles, when the car is smoking.

    Can the valve stem seal repair be completed without removing the engine?

    The only major component that needs to be removed is the valve covers. This is what makes the repair so affordable!
