Thanks for the detailed video. I did this on my 1991 C1500 4.3 with your video. Turned out great.

[UberGringo]

Guy at the shop told me it would take his guy about 4 hours to do this job. It's gonna be 4 hours cleaning!

[obs_vell]

I need to change mine. I know i can do the job, I just dont want to mess up the timing but wish me luck

Excellent tutorial. Subscribed. Have watched it about ten times in my own intake gasket journey.

I tried my best to label the various cables and took pictures, too, but I don’t know how it’s going to work out, lol.

What grit sandpaper were you using?

[randyization]

giving socket sizes need would have been a big plus.

Cool vid, thanks for making it. Do you recommend replacing the quick-release heater hose fitting at the back of the intake with a normal hose fitting? I've heard they leak as they age. Also, the workshop manual I saw said intake bolts are torqued to 35 ft pounds and not 25? UPDATE: My heater hose snapped off so easily while trying to unscrew it, definitely replace it.

and always check timing after job is complete does take much to throw it out. just done one today even though it lined right back i still was 2 degrees -

I see you didn't speak about the egr valve portion of the intake gasket. I replaced my engine and noticed that the egr ports on the passenger cylinder head between 6 and 8 don't exsist. I'm trying to figure out why I keep getting a code 32 for the egr valve and the only thing I've figured is that my old engine never had the holes in the cylinder head and my reman engine does not have them either. is there something you can let me know regarding this? I've looked at all sorts of reman engines and none of them have these 2 ports on the passenger cylinder head. I can't find reman cylinder heads that show these ports either. I'm just trying to figure out my problem. my engine seems to run fine. but I still get the code 32. looking for some insight as to why this is being over looked.

The rear water ports being blocked off causes these engines to overheat. The correct gaskets have all 3 ports for each side fully open.

[mike-bjdk]

bolts are backward on the bracket you showed stud should be toward fron of engine with bracket off ac area

[joekamer]

out of curiosity what type of racket was that you using seems to be battery i didn't notice a hose

[miguelplascencia]

How common is it for these intake manifold to warp or crack I swear I have a intake manifold leak on my 91 k1500 did it once ran great for 1 month then started missing at idle again

[JosePerez-ofoi]

Will this cause coolant leak into oil pan??

[jorgequintanilla]

Do the two covered sides of the gasket go to the back?

[pauleyedwin]

Could have demonstrated adjusting distributor one notch. Still a good video.

Ok so I for sure have top dead center set but my rotor isn't facing forwards. The number 1 piston is up, timing mark is at 0 on harmonic balancer but dist isn't right.

When bought the truck #1 on cap started at like 7-8ish o'clock . Timing mark was about 180° from 0.

Am I missing something or did previous owner mess up? 🤔

[hootframes]

Can somebody please help me and tell me the dimensions of the nut that holds down the map sensor bracket. Before I lose my

[Nykstudio]

what is the compnent called that the radeator hose attaches too? the one with the gasket that you need to replace if you take it off

[kgbreviews]

I just found an oil leak on the upper driver side lf my 5.7. And god i hope it isn't coming from the intake.. Because that doesn't look like a cheap repair..
