Lets see if 20W50 makes a difference.. Chevy 355 oil pressure issue.

[@curlynigero6417]

My 96 suburban been reading low oil pressure since I had it bout a year and it still runs really good

[@Brunoguzman602]

I have same problem with my 98 f150 I was changing the oil pressure sensor and checked the presión and everything is good!! But reading low pressure on idle and still running very well!!

Ive got those same junky summit gauges in our 90 buick estate wagon. They work good but you cant see the needles at night.

[@beeterolds]

I wired the lights so its not so bad

[@UsefulEntertainment]

@@beeterolds mine light up too, i can see the numbers clear as day but i have to turn on the captans light above to see. Maybe mine are defective lol

[@ReIics1970]

Better oil pressure when you stop using detergent motor oil.... Non detergent motor oil is the best Especially for old gm v 8s.... my 388 gets 45 lbs at 200 f. 900rpm

[@steelavocado1]

God, maybe this’ll solve my issue. Got little to no oil pressure at idle on a fresh 327. Could possibly be cam bearings but everything else is new!

[@beeterolds]

Mine was a bad oil pump. Right out of the box

[@thomaslitty7874]

7 to 14 psi idle for some sbc is normal my 305 I freshly built ran around 10psi till you gave it gas and it would hold 40

[@adamlong54]

Run berrymans b12 chemtool for 20 min at 2k idle then drain and change oil . it will clean it out aka motor flush breaks down all the varnish sludge grit grime and dirty oil system deposits.

[@syafiqwawa4403]

My dmax 2007 also oil light will appear when i started my car…but if i step on oil pedal it will go off…it will appear again if i dont step on my pedal…after driving for 20-30 minutes, it will go off

[@cool62chev]

Thats a bummer!

[@HeadFlowInc]

Never mind, went back and watched the assembly video, you used the colored STP oil treatment style assembly lube. You’re right I think there’s a problem, sorry man. Hey, if you used engine assembly lube with High Pressure Moly Lube it will make the oil look contaminated. It will take several oil changes to flush out all the Moly. 😉👍

[@beeterolds]

Cut the filter apart last night.. There is zero metal in the filter media... Im going nuts here lol

[@trentdawg2832]

Tired small blocks love that thick 20/50.....I swore by that shit before the LS bug bit me!!!!......but that motor doesn't sound or look tired. ....what gives??

[@beeterolds]

Probably something stupid.. I truthfully dont even feel like messing with it

[@waylonmccrae3546]

You only need about 8 psi. Per 1000 R.P.M. in those older Bowties - It'll be just fine !! 🙂

[@Ryanblake86]

Did you ever get to the bottom of it?

[@beeterolds]

Ya i sold it lol

[@priestthurmond754]

Carb flooding

[@CSXT8250]

No.. Not another wiped out cam. 😡

[@strangehappenings8961]

Looked silvery, probably cam bearings amigo.

[@beeterolds]

Sold it over a yr ago

[@roberthanna4400]

Damn😿
