    It’s funny I haven’t used that hand pump since 2020 when I filled my 5spd B1H diff and I can’t remember if it came with a bottle or a straw to reach the bottom of the bottle, so I improvised with the Gatorade bottle and some heater hose, it workedLOL

    Oof, I am not an expert with DSM's by any means but I have heard that these should have a sealed catch can...I have heard that people run vented without issue though. Are you running MAF or Speed Density?This was super helpful for me: You must...

    No. I havnt had any issues with the dipstick so far. The last upgrades and dyno was 7 years ago so I’m seeing some rotted caps here and there. I’m also struggling with fluctuating afr. It was idle hunting and running lean at idle…. Around...

    No. It’s a Magnus intake. Not sure on what throttle body it is but there are a few ports on the top that are all capped. Is that where I should run the hose to?

    True dat! Which may explain the setup...19eclipse90, would he be able to connect to another intake nipple? Does it have to be that specific one that is intend for the PCV. Like if he were to t off of the brake booster line, would that work?
  • 19Eclipse90 replied to the thread PCV valve.

    Ah, I didn’t notice that.It should be connected by a hose to the intake plenum. Kinda hard to see but it does not appear that you have an original intake manifold, though, so maybe easier said than done.

    If I were you I would take that cap off. Check to ensure the PCV only blows air one way (out of engine). Connect a hose from it to the big nipple that is down behind the fuel rail right behind the PCV. Then, like 19eclipse90 point out, take that...

    I've replaced crank sensor, pigtail, and checked continuity of all wires. All seems fine
  • Maple guy replied to the thread PCV valve.

    The valve is capped not open. Is it just supposed to blow the cap off if there is too much pressure buildup?

    This is your PCV valve.You must be registered to see element.The port with the filter on it is a breather. It should be connected to the intake pipe by a hose to pull gases out of the crankcase.

    Public track? Never heard of that. The way you access these tracks is by finding a club that offers admission.
