  3. Low oil pressure after highway trip

    in KExx Corolla Discussion

    Posted

    The only reason why I suggested the oil, from past experience rallying the Christ out of the little k motors with cheap oil it couldn't hold pressure at idle even with a freshly rebuilt motor, when you look into different brand oils with their technical charts, a lot of conventional oils have a particular temperature threshold when hot before the physical integrity of the oil starts to fail, more specific/quality brands have a higher temperature threshold thus hold up far better/ don't thin out as much,

    Yeah true, I've noticed in the past, presumably the engine was in good running order before stored, when I've used a motor that has been sitting a while with poor compression, when being used again, rust deposits from valve seats and any gunk contained in the piston ring grooves (causing the rings not to expand) eventually blow their way out which certainly give better results down the track,

  22. Rough 3K Idle

    in General Mechanical

    Posted

    so the secret places ive found vacuum leaks are inside the carby!! which take air from within the normal airflow so you can't test for them.

    1. hot idle compensator rubber valve under the little plate with 3 screws on the side of the carb (stuck open or simply leaking)

    2. 2ND barrel butterfly valve

    3. Power valve piston air bleed port due to worn power piston or walls

    4. gasket between the bottom plate and main carby body leaking into the manifold area.

    5. PCV valve itself, it may shake and appear corret based on the standard tetsing procedures, but i managed to only solve my biggest idling issue by creating a plastic seat inside my dissmantle-able PCV valve, which gives a near perfect seal under high vacuum idle conditions. The standard PCV valve does not. This is especially useful (required) if running a 3K carb on a bored out 3k block, or a 4K block.

     

    And if you're really unlucky you will have what i had, where the intake valve guides and seals have been destroyed at the same time from use of a synthetic oil in this ʞ©$ɟing engine. This will be evident pretty soon with blue smoke out the exhaust. HOW IS THIS POSSIBLE YOU ASK?

    Synthetic oil does 2 bad things for this engine,

    1. looses pressure to the top of the engine dramatically, and

    2. warps the valve stem seals.

    those two things cause 2 severe issues,

    1. no oil pressure at top end means hot as top end and also a lateral force applied to the valves by the rocker arms, du e to shit lubrication, which causes valve shafts to expand and damage the guides

    the ability for synthetic oil to move more freely ( do not tell me it doesn't you are wrong) for a given viscosity compared to mineral oil, makes it loose pressure in the journals of stock engines. These engines have relatively loose bearing journals from factory.

    2. synthetic oil will warp valve stem seals if they are allowed to be expanded lateraly from the above issue

     

    Agreed!
