A little help with a chevy 350

Stock type Melling brand lifters are $10 each at Autozone.

Yeah, I knew they could be had for a lot less than 350 bucks like was mentioned earlier.........I have Crane SBC lifters in my Twin Cam Harley....yeah, they are direct replacements....I paid 200 bucks for a set of 16 shipped from Summit. That was enough for 4 of us to do cam swaps/engine builds.

I think those torque values were for the non-vortec cast iron intake.
30 ft pounds sounds like way too much.

The gasket set is Felpro# MS 98000T
Use black or orange Permatex gasket sealant on the front and rear lip.
The aviation sealant is too thin...DO NOT USE.
Run a thick bead and extend it up onto the intake gasket just a bit.

Just found the torque specs..i wrote them on my gasket box,
First round tighten them to 44 inch pounds,then go back and tighten to 89 inch pounds.
That info came from my local Chevy dealer.

That gasket set includes the gaskets to remove the plastic part or plenum of the upper intake.
You do not need to do that.Pull the intake and fuel injection all as one piece.

Also all of the wire connections are different so its east to get everything plugged back in to the right place.

My neighbor and i done the whole job in 8 hours start to finish.

The gasket set comes with only one valve cover gasket because that is all that is needed to remove the intake.(remove drivers side valve cover)
I ended up just buying a set and replacing both valve cover gaskets with the thick blue rubber Felpro set.

Hey Gary,
I am ordering the parts to do this fix.
Which version of the Permatex sealent to use exactly.
Autozone has several Permatex brand sealants but they do not say what color they are.

I am guessing it is a silicone sealent verus a brush on sealant.
Thanks

Correct, in fact the gasket kit my buddies used, which was the better, more expensive kit, came with a small tube of RTV silicone. Just enough to do the job.

The truck is now running great again!

Good luck with yours.

Cool, did not realize that.
Thanks

Re: A little help with a chevy 350

Anti freeze is very corrosive to engine bearings, literally will eat them because of the material they are made from. Look to be replacing/rebuilding engine in the not distant future if the engine was run very long with the oil contaiminated. The bearings get eaten away causing too much clearance between rods and caps and crankshaft and their caps..this results in lower oil pressure. Eventually the clearance issues will become bad to the point there is very little to no oil pressure which will cause the engine to seize. Its basically the same thing that happens when an engine is worn out and in need of bearings...the anti freeze destroying the bearings only hastens the process quite a bit. Good luck friend.

As an afterthought I will add that I'm assuming the orange anti freeze has the same corrosive properties as the normal green stuff.. I've never had any experience with the orange. Hopefully it doesn't.

Well, I hope the engine in my buddies truck keeps going. It has been running great last I heard.

why would antifreeze be so corrosive to the bearings, yet act as an anti-corrosive in the engine cooling system?

A chemical reaction to the bearing material is what causes the damage. Its not like its abrasive.The engine block and other components the coolant is in contact with on a regular basis is not the same material the bearings are constructed from. Keep an eye on oil pressure the next couple months and listen for any increase in rod tapping. Hope all stays well.

Re: A little help with a chevy 350

I am finally in the middle of tearing down the 5.7L in my 99 Tahoe.
How many bolts hold the intake to the heads?
There are two at each corner about 2inches apart.
Seems like a lot of distance to have none more from front to back.
Does the plastic upper half have to come off to get to more intake to head bolts?

And how does the dang rad fan come off? Used to be four small bolts and then you tapped it off of a pilot.

You only have the two bolts at each corner of the intake.

The fan doesn't need to come off.

Sorry for the short answer but I've got to run.

Good luck!!
