    Cam Angel Sensor! Timing

    It should look like this: Make sure the crank is pointing at "zero" and both cam gears are aligned to the index mark on the back plate.

    can this be done?

    The real question is what if there was a way to bypass the knock sensors? Would you do it vs paying for the kit? If the answer to that question is "yes", you are in for a tough time keeping this engine running well. It indicates a willingness to take short cuts...the 7M will bite you hard...

    can this be done?

    I thought that's what you were getting at...so, following that logic: Bypass the pesky coolant temp sensor...no more code 22. And, how about the O2 sensor too...no more code 21 Two more less things to "worry about". See where I'm going with this? Instead of looking for ways to bypass...

    can this be done?

    And why would you want to do that?

    boost cut

    That's the problem with reading stuff off a forum...the written word is imperfect when it comes to what is trying to be communicated. No voice inflection, tone, etc...not to mention some of the grammer/spelling I've seen around here ;) (87mgte, I don't mean you...just in general)

    engine bogging down

    You're not listening ;) An ECU re-set is not going to do squat if you have a code 52. In fact, what other codes do you have?

    I was referring to this ;)

    Flat Tappets, old motors and ZDDP

    Or the 1J or 2J motors...and the amount of ZDDP in modern oils have little to no impact as to why there's no issue in these motors ;)

    Flat Tappets, old motors and ZDDP

    That's my whole point Shredder...the forces exerted against a flat tappet is far more due to the design. The rocker arm, seat pressures, and valve size/weight make a huge impact. If you look at it in a very narrow way, the cam lobe pushing against a flat shim on a 7M is the only comparison...

    Flat Tappets, old motors and ZDDP

    You're leaving a couple minor things out...like the spring pressures. On a 7M spring pressures range: Stock - 35 lbs Comp Cams - 55 lbs BC - 60 lbs Ferrea - 67 lbs (std dual spring) On a SBC the pressures range from 85 lbs stock to 130 lbs on a built motor...this greatly increases the...

    Flat Tappets, old motors and ZDDP

    Lack of oil supply is the cause...no amount of ZDDP is going to help that (hence the TSB). I'm still waiting on the explanation of these "similarities" between the valve train in a flat tappet engine and the 7M. Sorry...just don't see it. Like I said, if you want more ZDDP run a diesel...

    Flat Tappets, old motors and ZDDP

    The only thing similar is the shim surface is flat...that's it. Unless you would like to educate me on how the 7M valve train set-up is similar to the way flat tappets work in a SBC ;) And I'd like to see a set of 7M, 1J or 2 J cams with excessive wear on the lobes.

    Flat Tappets, old motors and ZDDP

    Yes it is...if you want more ZDDP in your oil, use diesel oil. There are also additives available. For a Supra, the ZDDP levels are not as critical.

    Conventional Oil Filters

    Nick - From what I understand, the old Denso filters were pretty good...I've never had one though and did not have the opportunity to cut one open. All the ones I've seen in the US as of late are made in Thailand.

    Any aviation lovers in the house?

    As long as it's correctable, you should have no problem getting an FAA medical John ;)

    Need help with 1.5jz build

    Hmmm...not possible it was the owner and pushing the motor past the tune huh? ;)

    So, I'm going to full coverage insurance on my car....

    That's exactly what he's saying...correctly too. That is if you want to get above what "market valve" for the car is if it's totaled.
