Friday I started my plenum repair. as well as a planned lifter, pushrod, HS 1.7's were already in..timing chain and water pump install.. ( whew!) Along with the essentials.. plugs, wires, cap, rotor, thermostat, I also went ahead and changed the ECT's, and the IAT.. Well, got it down to the lifters in about 3 hours...strange.. but when getting ready to unbolt the manifold.. they all werent there.. one was missing... the one passenger side.. last one under the firewall.. HMMM strange I thought.. and this truck never lost a drop of fluid...well lo and behold.. when I pulled the intake off.. there was what was left of the bolt sitting there.. it had broke off who knows when justwhere the head would have been.. luckily.. sprayed some rust buster.. grabbed it with vise grips.. just a bit of back and forth.. then broke it free and out it came.. ( whew #2 )so took my time today ( Saturday ) cleaning, painting and reassembling the intake, then installed lifters, rods and rockers.....decided to do the install of the intake tomorrow...
I went down to the local Fishers to get the sensors I decided to replace.. 2 ECT's and the IAT.. and wanted to find something to try to clean up the injectors before putting them back in the intake and buttoning up the fuel rail....had a talk with the master builder in the maching shop in back.. he was saying he only RTV's around the water jackets when hes doing the lower intake gaskets.... ( intake to head gaskets..) I had told him.. I have two sets of gaskets.. felpro.. and a set that came with the Hughes kit.. Victor Reinz set.. they are identical...except the FelPro kit came with all cork front and back gaskets.. the Reinz kit came with the rubber/metal type... either way I had told him I was thinking of RTV'ing around all the ports and jackets on both sides of the gasket... RTV the head..place the gasket.. RTV the manifold... place the manifold in place....he said first.. most RTV isnt resistant to fuel..so it may not be good for use around the ports where the injectors are going to be spraying.. second.. the metal gaskets for the intake are meant to be fairly rigid and RTV might cause some gapping.... (??? )
So heres my question.. for the guys who have done it... Are you RTV'ing when you do these gaskets.. and where? I have always done a small ( 1/8 inch ) bead around every port and perimeter.. both sides...if so.. what kind are you guys using.. ultra black? ultra gold? I'm ready to put this thing back on tomorrow.. ( we're supposed to have some crappy weather so we'll see...) then start the timing chain and water pump... Thanks in advance for any replies guys....

 

when i did mine, the only rtv i used on the manifold was a generous glob where the front and rear rubber gaskets meet the head. (this is the intersection of the 4 gasket pieces).

if i had a choice of cork vs rubber/metal, i'd use the rubber/metal, but would not put rtv anywhere except an intersection.

on the water pump and timing chain, i put a light coat of rtv on both sides of everything, surrounding every bolt hole and water jacket. i use the higher-heat version.

 

I use RTV for coolant exposed surfaces. For surfaces where there is a possibility of fuel or oil, go with the black stuff made for that purpose. We're not talking about a big price difference, and the black can be used for coolant and petroleum resistance.

 

Thanks for the replies guys..

 

That's how i do it too. I also let it tac up for a few minutes before placing the intake.

 

Used those crap cork gaskets & black rtvunder my m1 with my first cam. Leaked.Id only use the rubber ones across the valley. Water pump didnt leak giving bothsides a light coat as mentioned above.
Hear a lot of guys say the Right Stuff is really good and better than the black rtv though i havent tried it (yet).

 

Thanks again for the replies.... the lifters, pushrods, rockers, intake, plugs wires and cap and rotor are in... got the timing chain and water pump off as well today.

Thanks again....

 

Lucky you, I was planning on crawling under mine today but barely hit 40deg today and had a pool of water in the garage (under the truck) after yesterdays storm. Still waiting for spring to arrive [:@]

 

Yeah.. I took time off of work to get all this done... Monday it was 42 and windy as hell, today its flurrying a few miles away..( in alittle higher altitude..) but I still went out and started putting things back together..I ordered a timing set that hasnt arrived so I was busy cleaning the engine compartment.... and hooking everything that I could back up hoping that damn timing set would show... nope... I have a new stock set from Napa.. but its direct replacement.. single chain type... I am going to put off the timing cover for one more day...hopingthe timing setwill show.. then bolt it up and get the accessories back on and turn it over to see if I screwed up anything.. ( leaks!!!! )
