  1. Realized I never came back an posted updates.... ended up resurfacing the heads and block decks by hand lapping. I used bluing dye to monitor progress on each. The fire ring imprints were still on the block decks from the first set of head gaskets, so I think that is why they failed after only 60k miles.

     

    Here is what the block deck looked like on disassembly...

  2. just over 11y here and you guyz still haven't told me what the best oils is for my LGT.

    After my 05 wagon was no longer sustainable, the spec b became DD and a '20 Stinger GT1 is the new garage queen.

     

    16 Years here...

     

    Shell Rotella T6 5W-40. You're welcome! :lol:

  3. I just ordered the updated 11044AA770 Subaru EJ257 gaskets for the rebuild. Going to pull the engine, pull the heads off and try to determine the failure mode. After I clean the head and block, I plan to check for flatness and finish. Probably will lap the head. Not sure about the block.

     

    While I'm at it, going to do the timing belt and idlers along with the release bearing for the clutch.

  4. Argh.... 65K miles (4.5 years) on the rebuild and it looks like I've got an internal head gasket failure, again. I heard sloshing in my coolant system on cold start last week and verified this weekend that the engine is slowly pushing coolant to the overflow reservoir.

     

    It's frustrating. I did everything right, I thought. Machined the heads, had the block checked, installed heads with ARP head studs, etc. I used Fel-Pro MLS gaskets. Could this be the issue? This is the same failure mode I had the first time (combustion gasses leaking into the coolant).

     

    Just trying to get some ideas before I decide on what to do going forward. Thanks.

  5. ......the gap on the plug had been reduced to almost nothing even though there was no evidence or witness marks that something had impacted it. Swapped in a new plug just out of curiosity and my misfire was gone, obviously still knocked though.

     

    Cylinder heads came off today and the ringland failed on cyl 3 so I am assuming a piece of the piston impacted the plug and then exited via exhaust valve.

     

    :icon_sad:

  6. Bump from the dead.... to answer a question from earlier in this thread and ask a new one.

     

    Are H-tech springs on stock OEM struts hard on the struts and will they impact the life?

     

    Um... NO! I am at 232K miles and I think I just lost one (or both) of my rear struts in the past 3 weeks. The tail of the car seems to hop to the right on bumps and feels "floaty" at speed. As soon as the weather cools down, I'm putting new struts on all 4 corners. Shocking how long the OEM struts lasted.

     

    Going to put H-techs back on the front, but thinking of putting the stock OEM springs on the rear. The rear has always looked/sat too low for me.

     

    Has anyone else done this?
