Timing cover or intake oil leak?

[1998 K1500 Bubbles]

I was crawling under my 1998 k1500 today and found a ton of oil leaking down the passenger side of the block and on the front diff. I followed it up and it was running out from behind the accessory drive down the front bottom side of the passenger head. It also looks pretty oily behind the accessory drive but don’t know if it’s the timing cover leaking or intake leaking?

The factory plastic intake gaskets are junk. That's where I'd check first.

Go to a do-it-yourself "high pressure" car wash.

CLEAN the engine. Start it up, let it dry off. Drive around for awhile.

Blow baby powder all over the front of the engine. The oily baby powder will show you where it's leaking.

OR

After you've cleaned and dried the engine, dump some fluorescent dye in the oil, and buy the blacklight and glasses that help you see the glowing trail of oil.

But there's cheap-crap knockoffs on Amazon starting at about $17.

No need to clean the engine if you're using dye to find the leak. The oil already leaked lacks the dye so won't reveal under the light. And you don't need a kit. Get a quality dye and a quality light. I used AutoPro UV dye and an UltraFire 502B flashlight and they were perfect together.
