Oil leaking on starter bolts 2003 Silverado 2500HD

In this video, I’m troubleshooting my oil leak. I found oil leaking from the top of my starter. With further investigation it was the crank shaft sensor located just above the starter. If you have an oil leak and you have oil dripping near the starter bolts check out this sensor. It just might be the fix.

Have the same leak, above the starter, took 2003 Tahoe to a shop and they said oil pan. Replaced oil pan gasket for $950.00 and STILL have same leak. Thanks for the video.

Good luck👍🏻

I have same oil leak on my 2003 Tahoe 5.3L with 148k miles. I thought it was main seal. But then found this video.

[@Reserector]

I have this exact year and model with the same leak. I had no idea there was a sensor there! Thank you for posting this.

[@HighRidgeHandyman]

Good luck👍🏻

Hey that help with the leak

[@joeldelaney5769]

Mine is leaking from the same spot. I at first thought it was the oil pan gasket ,put new on, then figured id try the valve cover gaskets, put new ones on, then I replaced this sensor. And still have a leak. It does seem a bit less of a leak than before which is good. Looking above the starter, it doesnt look like it is coming from any higher up the engine. Thinking its got to be rear cover or rear main seal.

[@RussellBooth1977]

I have heard of them leaking from the camshaft position sensor as well but in my 15 years of owning a 5.7 litre Chevrolet LS1 V8 powered Holden VY SS Commodore I have never had then leak on me. The car is 21 years old now &: the engine has done almost 394,000 kilometres (245,000 miles) & I have replaced the front & rear main oil seals, hydraulic lifters, front & rear crankshaft oil seal carrier gaskets,oil pan gasket,etc.. So,it had been leaking from the tear main oil seal up until 7 years ago when I replaced it !

Yo High Ridge Handyman stumbled across this video my 2004 6.0 Escalade Ext was/is a mess progress is incremental but I am achieving success in areas anyways thanks because this is definitely one of my leaks the other is above oil filter on the oil coolant line block and galley plug thanks for video and time taken to show this to the world $68 at O’Reilly’s

[@HighRidgeHandyman]

Good luck Devil Doc. Thank you much appreciated👍🏻

[@DonBMW]

Cool! Thanks for sharing. Ran the UV fluid and it pointed me right to the starter and had me scratching my head. Had already checked the valve covers, and oil pan which were nice and dry. Now its either this o ring or the RMS. Will change out the o-ring on this sensor this week.

[@HighRidgeHandyman]

Good luck Don👍🏻 let me know how it works out for you. Take care bro

[@victor_beltran]

Hope you can give update on your situation did replacing this part fox the leak for you or did it end up being rear main seal

[@DonBMW]

@@victor_beltran It was the rear main seal after all. The sensor was dry. The RMS was not that bad to change. Took a weekend and used a Victor Reinz kit from O’Reily. Been nice and dry ever since.

Also followed these dudes here for removing the trans and also documented some good tips. m.kzbin.info/www/bejne/nZ29Y59sfrSairc

Always use oil UV dye from auto parts store with the black light whenever you can't find exactly where the leak is

[@thehandymancan9187]

If the oil leak is your only problem you can get a replacement o ring from rock auto for 3 bucks

[@HighRidgeHandyman]

If it were only that easy. Rock Auto is definitely the site for all your auto part needs👍🏻

Thanks man.

[@cellujuegos7844]

Great video thanks

[@HighRidgeHandyman]

Good luck. Thanks for watching 👍🏻👍🏻

[@clintonbirdsr.8598]

was it the crankshaft sensor? in the end? I have oil leaking too from above oil filter and starter. On 2001 gmc sierra 6.0

[@HighRidgeHandyman]

Unfortunately no. That had a small leak but it turned out to be the rear main seal most likely. I waited for a call back from a mechanic and in the mean time I tried that AT 205 reseal. Believe it or not it did the job so far. Check out my latest video on it. Thanks for watching Clinton👍🏻👍🏻

[@MrTheman18]

@@HighRidgeHandyman do have to put it in everytime you change your oil.

[@20tea]

@@MrTheman18 No, just occasionally. Could be every few months. You'll notice the leak returns once and a while. Just add it when you notice leaks. If it's too big a leak, may end up replacing the seal.

[@MrSilvernblackblood]

@@HighRidgeHandyman what did it end up being? The rear main seal? Valley pan gasket?

[@brendanokeefemusic-]

@@HighRidgeHandyman is that AT 205 still working?

[@franciskersher8576]

Did this turn out to be your problem and not the main seal?

[@HighRidgeHandyman]

Value cover gasket

[@chachifeere]

Mine is leaking in same spot. But looks like the oil pan. But I might be the sensor

[@HighRidgeHandyman]

Try the sensor first. Mine ended up being the valve cover gasket from above😡

[@chachifeere]

@@HighRidgeHandyman ya I checked min they not leaking at the back. This leak it too quickly. Coming from the crank sensors or oil pan at the back corner below starter, just did tranny swap and rear main and stop leaking now we have this leak

[@roltyd22]

How is it possible these leak oil if they're not under any pressure?

[@HighRidgeHandyman]

It’s not leaking out of the actual starter bolts but the sensor located on the top side where the starter sits. The crankshaft sensor

[@roltyd22]

@@HighRidgeHandyman Oh ok So that sensor is in an open hole into the block or whatever and it gets oil inside on the sensor the o ring goes bad it blows out..hope i got that right

[@roltyd22]

@@HighRidgeHandyman If that's the case i hope i can find a compatible o ring instead of buying a new sensor

[@brendanokeefemusic-]

@@roltyd22 did the o ring work?

[@roltyd22]

@@brendanokeefemusic-Found out its the rear main..bummer..it wasn't the sensor plus a small leak at back of passenger valve cover

[@martywoodlee2939]

WHY CANT YOU JUST REPLACE THE O-RING ?

[@HighRidgeHandyman]

It needed to be replaced. I was getting faulty readings at the gauge.

[@zabodyn1]

why not just put a new O Ring on the old sensor for .57 cents

[@HighRidgeHandyman]

Would have but the sensor was actually defective giving me false readings

[@MegaHowtoMan]

Where do you find the o ring?

[@chrisg1364]

What if its not the sensor, valve cover or sensor up top smh

[@HighRidgeHandyman]

Could be rear main seal. Turned out I have slow leak in valve cover gasket on the backside that would find it’s way down
