    Tahoe idle oil pressure

    They're supposed to idle warm at around 40psi, I'm getting around 28psi. So not great but itll due for the immediate future

    Tahoe idle oil pressure

    Great to hear, thanks. I'll still get it done asap but at least I know it's okay for the immediate future.

    Tahoe idle oil pressure

    I may overfill or I may just throw the parts in ASAP. May start removing the front diff in the morning. Do you think the truck is safe to drive still without any damage in the near future?

    Tahoe idle oil pressure

    I think the next step for me is going to be to drop the oil pan and replace that o ring along with the pan gasket. It's worth it either way because after visual inspection its leaking a bit

    Tahoe idle oil pressure

    Actually managed to get it in, this is warm idle. So pressure is actually low. this gauge shows very slightly higher than the built in one

    Tahoe idle oil pressure

    Theres no way I'm fitting this tester into the port. Is there any easier spot to test this?

    Tahoe idle oil pressure

    For the oil pickup tube o ring, does the color matter? I know theres red, green, and black. Not sure what's in mine but no matter the color would this Fel-Pro one work?

    Tahoe idle oil pressure

    For changing oil do yall think a PF46E will be fine? They have a PF61E that is longer, but I realized that after I bought the P46E. I also may throw in some 10w40 or something that'll help increase the oil pressure a bit.

    Tahoe idle oil pressure

    I think I'll buy an adapter on Amazon.... lol. I'm also considering just running a thicker oil like 10w40 for now to buy me some time because I'm low on funds at the moment.

    Tahoe idle oil pressure

    So I got the oil pressure tester. But I dont believe any of these are the right size? Reading online it seems like it's a 16mm male into the threads where the oil pressure sending unit goes.

    Tahoe idle oil pressure

    Let me know what you guys think. I'm on a budget and I'm thinking about catching the oil that is in the engine, putting in a better filter and reusing the oil for now, as it's not very old at all. The oil looks okay on the dipstick so I see no reason not to unless theres like metal chunks in it.

    Tahoe idle oil pressure

    Diagnosis is going to happen ASAP, oil pressure at idle is down to about 21 today, was like 27 yesterday. Did a rev test to see how high I could possibly go, at 5k rpm I had just below 50psi oil pressure, so definitely going to keep it at 4k rpm or below. As for an oil filter, how do you guys...

    Tahoe idle oil pressure

    Wow that sucks for that Sierra! Were you able to salvage the engines lower half without any major troubles? Also I never tow with the Tahoe at all, it has a hitch receiver so the previous owner before 2019 when my mother owned it probably did, but not in years now. Would this oil pressure...

    Tahoe idle oil pressure

    I'll check with a mechanical gauge ASAP. I will also change the oil and filter with high quality stuff if it actually has low oil pressure. From there I'll test the o ring if needed. As for the cracked head theory this truck has never used any coolant whatsoever, I've never had to even top off...

    Tahoe idle oil pressure

    I think it may have a Supertech right now, not sure why I cheaped out on it a few months ago. I plan on changing it soon, 3500 miles into a full synethetic change, but the oil looks pretty dark brown so I'll change sooner than later with probably a Mobil 1 or ACDelco filter.

    Tahoe idle oil pressure

    I haven't verified with hooking a gauge up yet, just going off of the one on the dash, and yeah I'm not sure I believe it either.

    Tahoe idle oil pressure

    Hi so my 05 tahoe with the 5.3 seems to have lowish oil pressure while idling. At idle it has around 25-27psi of oil pressure, compared to a few months ago where it was a steady 35-40psi. Oil was low the other day and I topped it off, but the oil pressure stayed the same.

    Suspension Rebuild

    Hi I'm looking into rebuilding the entire front and rear suspension of my 05 Tahoe. With it being such an old truck I dont want to spend the money on expensive parts. What cheaper brands from RockAuto would you guys recommend? I was looking and SKP and their parts don't look terrible. Also...

    2005 Tahoe Ticking

    So today I was going to remove the plugs and I wanted to pull the dipstick tube out, bit the bracket broke. But I still got the tube out with a struggle. However now without the bracket with it back in its loose, I think its fully seated. With it moving like this will I be able to get an...

    2005 Tahoe Ticking

    But coincidentally while still a low lean, the drivers side(bank 1) is still higher than the passenger side at 0.0% ST and LT, its got me thinking a small vacuum leak.

    2005 Tahoe Ticking

    Definitely the intake ports then, took the PCV line off and its fine. What about on the passenger side? I know the EVAP Purge solenoid can cause a vacuum leak too. But my fuel trims seem good so it must not be a huge leak.

    2005 Tahoe Ticking

    Update, cleaned throttle body and it's running the same except with a small vacuum leak coming back to idle from revving because one of the throttle body studs broke. Its idling at 490-500rpm, feels low to me and I'm wondering that's why its stumbling, because when I forgot a vacuum hose it was...

    2005 Tahoe Ticking

    I got copper ACDelcos from rockauto, the gap was way off when I got them. But I'm wondering if I gapped them too far.
