    5.3 Tick/Knock?

    Surprised there is no seal. Does that mean it is a tapered thread ? Sorry I'm weak on metric stuff. If it is tapered thread, you don't need much torque, you just need it tight. It should be easy enough to install the old one back on when you are ready, check for leaks.. then decide corrective...

    5.3 Tick/Knock?

    If the original plug is in good shape and you can get it back in with the seal intact, I'd just do that... no point replacing a plug that won't ever hopefully come out.

    SOLVED: Need to drop the fuel tank but it is currently 80% full

    Another idea to drop the fuel tank is to use a transmission jack or 2... Anytime I see a Harbor Freight jack on Facebook used "1 time only" for $50, I buy that sucker! It is a lifesaver. On a large tank like this, you can definitely use 2 jacks

    SOLVED: Need to drop the fuel tank but it is currently 80% full

    That's just my game, lol... (coming from the kludgy world of dual fuel tanks + selector valve).. What I usually do is hook up my spare transfer pump to the sending unit and siphon out all the fuel.... I have an Edelbrock 17301 spare (which I run on my carbureted trucks.) I imagine the fuel...

    5.3 Tick/Knock?

    Yeah I saw the working room there it is bad. Check this video below. Looks like another location to tap...... maybe the same place you were referring to... it does track the gauge closely though, so if this tap location shows 20 PSI when cold, I'd say you need more drastic measures

    You want to tap into where the oil pressure gauge is to compare vs gauge... will a kit like the one below help with better access ? It also comes with adapters...

    5.3 Tick/Knock?

    Well before you conclude that, try a manual oil pressure gauge. If 20psi oil pressure is confirmed, you can say the bearings are about done.

    5.3 Tick/Knock?

    Well... if the pan has been dropped for the first time ever, what you are seeing is well within norm for 200K miles!!! Unless you changed the oil every 3000 miles you will build non-zero sludge over time. Didn't the valve train look clean ??? In extreme cases you will even see sludge in the...

    5.3 Tick/Knock?

    What you are seeing is probably within realm of what is normal for a high mileage engine. By no means an example engine, but the bottom end is usually nasty and sludge does end up there, so do metal shavings. If your oil pressure returns to where it needs to be, you are probably fine. But I'd...

    5.3 Tick/Knock?

    It is a high mileage engine. It does appear to have had some poor oil change habits resulting in sludge. Sludge in oil pick-up tube filter can also drop the pressure, so hope you cleaned out the pick-up tube filter as well.

    Rear Main Seal OEM or Felpro

    That's really proximate to Summit Racing and Copart. I'm in North Dallas, specifically Richardson Y'all hit me up if there are any truck/car meets... Where in Dallas are you @S33k3r ? Really hope OP doesn't mind his thread getting hijacked!! Is that pretty common around here ? I'm on another...

    Rear Main Seal OEM or Felpro

    No problems. I’m convinced this tool is needed. When they transitioned to 1 piece rear main seals, the seal design became more durable but the difficulty of replacement also increased. So I’d definitely want to be equipped with all the arsenal!! Well if/when I may do this job (hopefully on...

    Rear Main Seal OEM or Felpro

    Ok I was wondering, why would it be necessary to remove the metal cover if you are only doing the RMS. Is the metal cover containing oil pressure and therefore the seals need to be done at the same time ? Again, I have no idea what the purpose of the metal cover is… just trying to understand...

    Rear Main Seal OEM or Felpro

    Thanks. Nice tool. Just a couple of dumb questions since I've never put my hands on a GM LS gen small block before. Wouldn't it be possible to remove the old seal and the cover together... then reinstall it together so the old seal works as a centering implement. If its not possible to remove...

    5.3 Tick/Knock?

    20PSI on cold idle is definitely not good (if true). I would definitely suspect the gauge itself... Again sending units can be bad as well. I always use OE parts so in this case an AC Delco or GM part. One below sounds like the correct one. I assumed you used this one...

    5.3 Tick/Knock?

    Sounds good. Interested to see what you find. Take pics of where you tap into for the mechanical gauge, etc..... and not sure if your plan is to have a gauge permanently, if so, I'd definitely use this instead of the cheap plastic tubing that comes with the mechanical gauge...

    02 Yukon Climate control gremlins

    Hi there! I got a few grelims on the climate controls on the 02 Yukon, nothing outrageous. I don't know how these work yet, do they run off vacuum or if they electrically actuated... (well I think I have figured out that part... sounds like electric) ? Issues: 1) Few weeks ago when I plugged...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Great point… probably the reason for wear from the previous owner. I have never used more than just the key(s) for the vehicle on the ignition cylinder. I have replaced many ignition switches on my 80s pickups I bought used … a heavy keychain will certainly accelerate wear on both the cylinder...

    5.3 Tick/Knock?

    I would suspect the gauge as well on such a drastic drop.... what you have there I'm sure is no perfect gauge... on all my old trucks I have a mechanical oil pressure gauge installed. If you are worried about that o-ring, by all means drop that pan and change it. No big deal.

    5.3 Tick/Knock?

    That is plenty of oil pressure in my opinion. When you rev it are you over 50PSI ? Didn't you say your engine has 200K miles ? If so you are in good shape for the miles.

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Oh I gotcha... I think we figured out the parasitic loss. It happens when the vehicle is turned off, key removed, and dinging won't stop with the door open. What I end up doing is re-inserting the ignition key, moving the key to run position, bringing it to off again. It's almost like the...

    Stalling while driving.

    If you have a frame mount fuel filter, if it’s clogged it could affect pressure… the clog may be intermittent depending on the particulates and where they are … when you turn off the vehicle any backflow can temporarily unclog .. similar to any filter in oil pickup tubes in engine/trans

    Thanks, how about the rear audio/radio controls ? They seem inactive except the Power button.

    Rear Main Seal

    What can the GM trucks do that the Fords cannot? Fire up the engine without a transmission!! Very cool !!
  25. viven44

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Yes there are some buttons back there. Power is the only thing that does anything (enables and disables radio). No response from any of the other buttons.... not sure what I am doing wrong.
