    @Bansheeboy11 Před 5 lety +94

    Just to add a quick note, the LH cam gears that are loaded are easy to mess up and bend the valves, they didnt do it the right way. The intake gear needs to be spun clockwise, the exhaust gear needs to be spun counter clockwise. Most of the time you can get away with doing it like they did but theres enough spring pressure that if one of the gears slips it will catch the edges of the valves and will easily bend them, and no one ever checks after they do it which can lead to the car running like crap, or turning the valves into a tossed salad.

    • @island03z
      @island03z Před 5 lety +3

      isnt it the other way around? for unloading the cams the intake goes counterclockwise exhaust goes clock wise

    • @ericbarney5036
      @ericbarney5036 Před 4 lety +6

      I don't think they are that easy to bend. I believe it's more of a precaution, so you don't take a impact or a breaker bar to the bolts. I'm picturing some ding dong kicking the breaker bar like he/she is trying to crack lugnuts on the side of 95.

    • @Natedoc808
      @Natedoc808 Před 4 lety +18

      the Key being to make sure the crank alignment mark and oil pump mark are lined up so the pistons are mid stroke and you don't bend the valves.

    great video , I've always been curious about how the block is parted thanks , removing the piston clips & pins was an eye opening , only flat 4 I've done was a VW this is way different obviously due to water cooling and overhead camshafts & cambelts and with VW the bores/barrels can be slide out of the crankcasing , knowledge and being methodical clearly is the only way to go with the Scooby engine, doesn't appear too difficult to dismantle I'm sure the rebuilding has lots of do's and don'ts that aren't so obvious at first ,cheers

    For the Cam gears: when you shear off a hardened 3/4” drive Allen trying to break it free, the factory may be fucking up putting them on that tightly. Strangely enough my USDM EJ205T had the hex shank to secure the cam from spinning but there is no way these bolts being so insanely difficult were torqued at the factory to the spec outline in the FSM. Edit: be very very careful with the cam bolts if doing HGs in the car, have to use a shallow, 6 point 10mm socket and be sure to tap the socket on deeply as the cam bolt heads are quite prone to stripping.

    Put this motor in a Factory Five 818 C . I am going for a WRX STI in the coupe I am building. 1900 lbs pushed by 310 horsepower. What a rocket.

    Looking at the complexity of this boxer engine, no wonder why Suby's engine repair cost usually more than a traditional inline 4.

    Seems that the cause of the burnt valveseat is either a bent valve or a damaged valve guide, as nam seems to need way more force than normal to pull this one valve out.

    The crank pulley in my instance does not want to pull off without a fight. Will see how it goes tomorrow

    Question: Nam said that on the USDM engines, there are no hex on the camshafts to put a wrench on to and if you don't have a special tool, there is another way to loosen the bolts. I have a stock US motor and no special tool. What is "the other way" to loosen and remove the cam gear bolts?

    I worked with cars for several years but nothing like replacing piston rings and seals. I got 2010 subaru forester 2.5l and I probably need to do that soon. I already got low compression on cylinder 4 @70psi. I didn't try the restore lubricant yet but if I try to rebuild the engine with new piston rings and seals and learning as I go with repair guide and some help... How long would it take me. I want to learn this stuff, do it right and use my subaru to learn it.
